It had its time of glory in the past. In ancient Greece, philosophy
    was not yet distinguished from the science of that time, thus we
    might say both were comparable in quality. Then they faced many
    centuries of near-absence during the dark ages of Christian
    domination, before resurrecting together and having their glory
    period in the time of Enlightenment.
    Enlightenment philosophy signed its good new insights of truth, by
    some valuable practical accomplishments (usefulness for mankind,
    that can be compared with the technical usefulness of science):
    
      - An initial impulse to the development of science
- Democracy, constitutions, separation of powers
- Declaration of human rights, the right of expression (outside
        religious dogmas)
- Criticism of religion, a limitation of the
        Church's domination, the separation of church and state
- Development of education and university
- More lately: the end of slavery, a criticism of the political
        & religious colonialism and of the arrogance towards
        other civilizations
However, the situation is now very different, as science made a
    tremendous lot of progress since that time, leaving philosophy far
    behind. Philosophy didn't make any comparable progress of
    methods or knowledge, and thus became a sterile discipline.
    
    Some attempts of reform to remodel philosophy after science
    have been made, such as the development of analytic philosophy
    by Bertrand Russel who also contributed to the new foundations of
    mathematics (set theory). It may be acknowledged that analytic
    philosophy is a bit less irrational than continental philosophy.
    But, apart from a few interesting clues such as his celestial teapot
    and other remarks on religion, much of the length of Russel's
    philosophy (such as his theory of the mind) remained of poor value
    (long developments on pointless details that cannot contribute to
    the progress of knowledge in any effective way). 
    
    For example, after the good fruits of democracy produced by the
    Enlightenment philosophy, what further political revolution did
    philosophy bring to mankind ? Well, it brought the Marxist
    revolution.
    Despite its claims, Marxism is not rational. Most philosophers did
    not notice the problem, and thus welcomed Marxism in their field.
    Only Karl Popper developed famous writings showing the
    discrepancy between Marxism and science, by observing the difference
    between the Marxist and the scientific way of testing a theory
    against experience (falsifiability), for example the way Einstein's
    general relativity made precise predictions to be tested. 
    
    Despite this, the community of so-called "intellectuals" (of
    humanities, not scientists) kept holding Marxism as a
    rational theory and valid philosophy. Of course if you measure
    a philosophy by its convincing power to the masses, then, Marxism is
    among the best, just in the same way religions previously were. In
    fact Marxism is itself a modern religion exploiting the newly
    fashionable claim of scientificity. But the success of a
    convincing power to the people (even to be taken as "scientific" by
    an unscientific class of self-proclaimed "intellectuals") hardly has
    anything to do with truth and rationality. 
    Now you don't need anymore to study and examine it in much details
    to find evidence for its lack of rationality: just look at its
    fruits (the Soviet Union). The combination of its convincing power
    with its utter falsity, just means it is at the antipodes of reason:
    it is powerfully misleading.
    We shall discuss this more closely in Part IV.
    
    The irrational character of philosophy, can be inferred from its
    inability to naturally converge to a consensus on given questions:
    many philosophers keep presenting opposite views on fixed issues,
    that remain unresolved for a very long time.
    
    Paul Graham's
      criticism of philosophy
     "When things are hard to
        understand, people who suspect they're nonsense generally keep
        quiet. There's no way to prove a text is meaningless. The
        closest you can get is to show that the official judges of some
        class of texts can't distinguish them from placebos.
      And so instead of denouncing philosophy, most people who
        suspected it was a waste of time just studied other things. That
        alone is fairly damning evidence, considering philosophy's
        claims. It's supposed to be about the ultimate truths. Surely
        all smart people would be interested in it, if it delivered on
        that promise.
      Because philosophy's flaws turned away the sort of people who
        might have corrected them, they tended to be self-perpetuating.
      "
      (and many other arguments worth reading too)
    
    
    Richard Feynman (physics Nobel laureate) made harsh criticisms of
    philosophy:
    
    
      
        
          | Richard
                Feynman wrote: | 
        
          | When I sat with the philosophers I listened to them
              discuss very seriously a book called Process and Reality
              by Whitehead. They were using words in a funny way, and I
              couldn’t quite understand what they were saying. (...) What happened [at the seminar] was typical—so typical that
              it was unbelievable, but true. (...). A student gave a
              report on the chapter to be studied that week. In it
              Whitehead kept using the words “essential object” in a
              particular technical way that presumably he had defined,
              but that I didn’t understand.
 After some discussion as to what “essential object”
              meant, the professor leading the seminar said something
              meant to clarify things and drew something that looked
              like lightning bolts on the blackboard. “Mr. Feynman,” he
              said, “would you say an electron is an ‘essential
              object’?”
 Well, now I was in trouble. I admitted that I hadn’t read
              the book, so I had no idea of what Whitehead meant by the
              phrase; I had only come to watch. “But,” I said, “I’ll try
              to answer the professor’s question if you will first
              answer a question from me, so I can have a better idea of
              what ‘essential object’ means. Is a brick an essential
              object?”
 What I had intended to do was to find out whether they
              thought theoretical constructs were essential objects. The
              electron is a theory that we use; it is so useful in
              understanding the way nature works that we can almost call
              it real. I wanted to make the idea of a theory clear by
              analogy. In the case of the brick, my next question was
              going to be, “What about the inside of the brick?”—and I
              would then point out that no one has ever seen the inside
              of a brick. Every time you break the brick, you only see
              the surface. That the brick has an inside is a simple
              theory which helps us understand things better. The theory
              of electrons is analogous. So I began by asking, “Is a
              brick an essential object?”
 Then the answers came out. One man stood up and
              said, “A brick as an individual, specific brick. That is
              what Whitehead means by an essential object.”
 Another man said, “No, it isn’t the individual brick
              that is an essential object; it’s the general character
              that all bricks have in common—their ‘brickiness’—that is
              the essential object.”
 Another guy got up and said, “No, it’s not in the bricks
              themselves. ‘Essential object’ means the idea in the mind
              that you get when you think of bricks.”
 Another guy got up, and another, and I tell you I have
              never heard such ingenious different ways of looking at a
              brick before. And, just like it should in all stories
              about philosophers, it ended up in complete chaos. In all
              their previous discussions they hadn’t even asked
              themselves whether such a simple object as a brick, much
              less an electron, is an “essential object.”

    "philosophy
        of science is about as useful to scientists as ornithology is to
        birds" 
    
    (forgetting that, in fact, ornithology has been useful to birds in
    some ways...) 
    
      People say to me, “Are you
          looking for the ultimate laws of physics?” No, I’m not… If it
          turns out there is a simple ultimate law which explains
          everything, so be it — that would be very nice to discover. If
          it turns out it’s like an onion with millions of layers… then
          that’s the way it is. But either way there’s Nature and she’s
          going to come out the way She is. So therefore when we go to
          investigate we shouldn’t predecide what it is we’re looking
          for only to find out more about it. Now you ask: “Why do you
          try to find out more about it?” If you began your
          investigation to get an answer to some deep philosophical
          question, you may be wrong. It may be that you can’t get an
          answer to that particular question just by finding out more
          about the character of Nature. But that’s not my interest in
          science; my interest in science is to simply find out about
          the world and the more I find out the better it is, I like to
          find out…
        (The Pleasure of Finding Things Out p. 23)
    
    From
this
      Feynman's text on science:
    
    ".
..what science is, is not what
        the philosophers have said it is, and certainly not what the
        teacher editions say it is. What it is, is a problem which I set
        for myself after I said I would give this talk.
        After some time, I was reminded of a little poem:
        A centipede was happy quite,
          until a toad in fun
          Said, "Pray, which leg comes after which?"
          This raised his doubts to such a pitch
          He fell distracted in the ditch
          Not knowing how to run.
        
        All my life, I have been doing science and known what it was,
        but what I have come to tell you--which foot comes after
        which--I am unable to do, and furthermore, I am worried by the
        analogy in the poem that when
          I go home I will no longer be able to do any research."
     From this
        Feynman's interview:
    "Philosophers, incidentally, say
        a great deal about what is absolutely necessary for science, and
        it is always, so far as one can see, rather naive and probably
        wrong. . . 
      My son is taking a course in
        philosophy, and last night we were looking at something by
        Spinoza--and there was the most childish reasoning! There were
        all these Attributes and Substances, all this meaningless
        chewing around, and we started to laugh. Now, how could we do
        that? Here's this great Dutch philosopher, and we're laughing at
        him. It's because there was no excuse for it! In that same
        period there was Newton, there was Harvey studying the
        circulation of the blood, there were people with methods of
        analysis by which progress was being made! You can take every
        one of Spinoza's propositions and take the contrary propositions
        and look at the world--and you can't tell which is right. Sure,
        people were awed because he had the courage to take on these
        great questions, but it doesn't do any good to have the courage
        if you can't get anywhere with the question.  
        It isn't the philosophy that gets me, it's the pomposity. If
        they'd just laugh at themselves! If they'd just say, "I think
        it's like this, but Von Leipzig thought it was like that, and he
        had a good shot at it too." If they'd explain that this is their
        best guess.... But so few of them do; instead, they seize on the
        possibility that there may not be any ultimate fundamental
        particle and say that you should stop work and ponder with great
        profundity. "You haven't thought deeply enough; first let me
        define the world for you." Well, I'm going to investigate it
        without defining it! "
      
    
    Another Physics Nobel laureate, Steven
        Weinberg, wrote (Chapter "Against Philosophy" of his book
      "Dreams of a final theory"):
    
      "The insights of philosophers have occasionally benefited
        physicists, but generally in a negative fashion—by protecting
        them from the preconceptions of other philosophers.(...) without
        some guidance from our preconceptions one could do nothing at
        all. It is just that philosophical principles have not generally
        provided us with the right preconceptions.
      Physicists do of course carry around with them a working
        philosophy. For most of us, it is a rough-and-ready realism, a
        belief in the objective reality of the ingredients of our
        scientific theories. But this has been learned through the
        experience of scientific research and rarely from the teachings
        of philosophers.
      This is not to deny all value to philosophy(...). But we should
        not expect [the philosophy of science] to provide today's
        scientists with any useful guidance about how to go about their
        work or about what they are likely to find.
      After a few years' infatuation with philosophy as an undergraduate
      I became disenchanted. The insights of the philosophers I studied
      seemed murky and inconsequential compared with the dazzling
      successes of physics and mathematics. From time to time since then
      I have tried to read current work on the philosophy of science.
      Some of it I found to be written in a jargon so impenetrable that
      I can only think that it aimed at impressing those who confound
      obscurity with profundity. (...) But only rarely did it seem to me
      to have anything to do with the work of science as I knew it.
      (...)
      I am not alone in this; I know of no one who has participated
      actively in the advance of physics in the postwar period whose
      research has been significantly helped by the work of
      philosophers. I raised in the previous chapter the problem of what
      Wigner calls the "unreasonable effectiveness" of mathematics; here
      I want to take up another equally puzzling phenomenon, the
      unreasonable ineffectiveness of philosophy.
      Even where philosophical doctrines have in the past been useful to
      scientists, they have generally lingered on too long, becoming of
      more harm than ever they were of use.(...)
      Mechanism had also been propagated beyond the boundaries of
      science and survived there to give later trouble to scientists. In
      the nineteenth century the heroic tradition of mechanism was
      incorporated, unhappily, into the dialectical materialism of Marx
      and Engels and their followers (...) and for a while dialectical
      materialism stood in the way of the acceptance of general
      relativity in the Soviet Union
      (...) We are not likely to know the right questions until we are
      close to knowing the answers.(...)
      The quark theory was only one step in a continuing process of
      reformulation of physical theory in terms that are more and more
      fundamental and at the same time farther and farther from everyday
      experience.

    "But… many introductory books on
        philosophy take the tack that “philosophy is not so much a set
        of answers as a way of asking questions: the important thing
        about philosophy is not specific answers, but rather the
        philosophical way of thinking”
        Yeah – that is because the answers that philosophers have come
        up with over the centuries have been almost uniformly bad!
        (...)
        Ethics is too important to be left to the philosophers.
        (...)
        children should also be taught not to think “philosophically,”
        in the manner of current and recent academic and professional
        philosophers. On the contrary, they should be explicitly told
        that, for at least the last two centuries, the philosophical
        enterprise as carried out by professional philosophers has been
        an obvious failure and that the vast increase in our knowledge
        of reality during the last several centuries has been due not to
        philosophy but to natural science."

Science, philosophy, and religion all make claims to have a

        they arrive at differ dramatically.
        It would be quite surprising if three such radically different
        approaches to confronting reality were to give compatible
        pictures of reality.
        Of course, they do not.

    Other philosophers try to justify philosophy's flaws through empty
    arguments:
    
    How pitiful it is to observe how philosophers
are
        not even able to give a decent answer to a simple question.
    They try to justify their inability of finding decent answers
      by claims such as : the value of philosophy would be to focus
      on asking the right questions (or eliminating the wrong questions)
      and eliminating some wrong answers (a sort of intellectual garbage
      collecting). But these are just blind unjustified beliefs,
      as the real effect of their work is just the opposite: to
      multiply and preciously accumulate wrong questions and wrong
      answers (intellectual garbage collectioning).
      This reminds me the joke
      "How many Microsoft engineers does it take to screw in a light
        bulb? None. They just define darkness as an industry standard."
      and other "It's not a bug, it's a feature".
    
    In reply to the criticism that philosophy lost its usefulness
      since the Enlightenment time, philosophers often react by
      glorifying themselves of their uselessness, by the straw man
      argument that, well, optimized financial productivity is not the
      right ultimate value, and thus should not be the exclusive purpose
      of public school curricula. 
      But, while I agree that numerical measure of the short-term
      financial profit should not be the final and exclusive criteria of
      value for an intellectual discipline, the trouble is that
      philosophers seem to have no other meaningful alternative criteria
      of value either, except the very negation of the usefulness
      criteria (together with their intimate but unjustified
      conviction). Namely, they seem to be raising wastefulness
      (uselessness) as their ultimate value, as if the very fact
      something brings no fruit, could serve as an evidence that it must
      surely be very spiritual. This reminds me the Shadoks'
      insights : 
    
    "
I
          pump, therefore I am
        It is better to pump even if nothing happens, than risk that
        something is going worse by not pumping...
        their rocket was not highly developed, but they had
        calculated that it still had 1 chance over 1 million to work.
        And they hurried to fail the 999 999 first tests to ensure
        that the millionth works."
    With wastefulness as their ultimate value, their work victoriously
    turns out to be universally wasteful, for whatever purpose including
    the development of the mind and critical thinking itself. The belief
    they must be good for the spirit or whatever undefinable ideal just
    based on the observation of their worthlessness for financial
    profit, is but a superstition among others. They may of course
    reject this criticism as straw man too, as this description is not
    exactly their claim, but it does not matter what they exactly claim:
    this is what they are doing in practice anyway.
    
    How to explain the failure of philosophy ? Well, once cause is the
    general dumbness of its members as will be illustrated by below
    examples, another important cause (maybe a corollary, the only
    remaining kind of thing dumb people have the ability to think about
    instead of serious issues) is its traditional obsession for essentialism (focusing on the ultimate
    nature of everything - well, by the way, this is precisely a usual
    character of cranks), to be contrasted with science's
      non-essentialism. Science has its own care for essences when
    needed; it is just not an obsession. Philosophy just failed to
    follow this model.
    We might also describe the difference between science and philosophy
    in this way:
    Science is the practice of rationality, while philosophy has
    theories of rationality. And these theories are usually wrong
    because disconnected from practice, because, in fact, there is no
    better way to understand rationality, than by practicing it. Which
    philosophers usually utterly fail at, despite their claims.
    
    But... is this really awful if philosophy is dominated by cranks ?
    Well, not necessarily. After all, in order for idiots to stop
    bothering scientists, they need to go somewhere else and find
    another public. So, philosophy can be considered useful for its
    social role of a huge intellectual bin where idiots can gather,
    while science on its own side can stay somewhat cleaner.
    
    OK, philosophy is so diverse that it may also be possible to find
    there a minority of decent approaches: a
      possible example (I only looked briefly) 
    Remarks on logical positivism and falsificationism
    As philosophers can easily notice, there is a flaw in the way
    Weinberg take the example of logical positivism and its unfortunate
    consequences for criticizing philosophy. Indeed, logical positivism
    was rather made by scientists themselves, precisely as a movement
    against philosophy, and was popular among scientists but not among
    philosophers, who quickly rejected it. Thus, philosophers cannot be
    responsible for these troubles.
    Let's explain this issue in more details.
    
    Once understood well, the statement of the principles of science,
    including the "logical positivism" principle, is not affected by
    Weinberg's criticism of logical positivism: the troubles only
    come from a caricatural form of logical positivism not balanced
    by other principles (conceptual reconstruction of reality).
    
    The difference made by philosophers between verificationism (as
    stated by logical positivists) and Popper's falsificationism (that
    was later widely taken as a reference of scientificity) is a
    mistake.
    Once analyzed well, these are more or less two ways of popularizing
    the same logical concept. Well, the details of the formulation of
    logical positivism can have been imperfect and deserve a few
    corrections. But the main difference is not about what they really
    mean, which is the same, but a difference of "how they feel", how
    they might be misinterpreted by irrational people.
    To the eyes of a large public as well as many philosophers, Marxism
    and Psychoanalysis made an impression of being "verified", thus
    scientific. But this impression of "verification" was a mere
    illusion, obtained by emptying of meaning the concept of
    "verification". Then, Karl Popper discovered that another phrasing,
    "falsificationism", was better suited and efficient to explain how
    Marxism and Psychoanalysis are false sciences, as they do not stand
    to the practice of verification used in real science. This was okay,
    but then he went to wrong conclusions by mistaking this
    difference of usefulness (for irrational people to more easily
    notice the lack of scientificity of some ideologies) for a deep
    conceptual difference. The result is that he replaced the
    initial misinterpretation of the nature of science, by another
    misinterpretation, that does not carry the same risks of misuse but
    can carry some too.
    As Weinberg said, the main possible value of philosophy is to refute
    some errors of other philosophers. So, Popper was good for warning
    against Psychoanalysis and Marxism as pseudo-sciences, while David Stove
    was good for warning against the irrationality of Popper and other
    science philosophers (Feyerabend, Kuhn...). Among his writings see
    for example Popper
        and After: Four Modern Irrationalists and What
        is Wrong with Our Thoughts? 
    
    Now some philosophers can still feel proud about all these remarks,
    putting forward that this is all a philosophical debate about the
    foundations of science which do not seem clear, so that philosophers
    are needed to warn people about this lack of clarity. Sorry, I still
    disagree. This problem is a problem for philosophers just because
    they have the wrong language to approach it. As I explained there,
    the solution requires some mathematics, namely the concept of information
      entropy. This is essentially equivalent to the approach of
    Bayesian inference, just generalized to any amount of complex,
    structured data with its correlations, while Bayesian inference
    focuses on only one observation or a repetition of uncorrelated
    instances of the same observation. (Now I am aware that just a
    mathematical formula like this does not solve all problems about
    verification/induction/falsification as remains the interpretation
    problem commented below). 
    So, what is the contribution of philosophers on this topic then ? It
    is essentially to mislead and turn into ridicule in the eyes of
    proper thinkers and scientifically aware people, some amateur thinkers such
      as those evangelists ("Inspiring Philosophy" youtube channel -
    as they tried to argue to me in private conversation, sorry I have
    not published the relevant excerpts) who went to follow and mistake
    as serious the courses they attended of "philosophy of science"
    given by philosophers and then proudly claim in debates with
    scientists that logical positivism is no more a basis of science,
    referring for this to the current fashion among philosophers. As if
    in matters of the foundations of science, the opinions of
    philosophers mattered Wouahahahaaaaaa
    
    So, what is logical positivism, and how alive is it, really ? I will
    tell you. Not that I studied any philosophical works about it. There
    would be no point to do so, really. Because, again, philosophical
    works hardly have any interest in general. The question, instead, is
    about which really are the features of the foundations of science in
    general, and the logical positivism aspect of these in particular.
    You won't find these in any philosophical work, because philosophers
    are not scientists and have no clue what they are talking about, any
    more than you can learn to become a good soldier just by reading any
    books about war, no matter how good such books may be. You need
    actual training. So, to get proper ideas on this, what you need
    instead is genuine experience as a scientist. 
    So:
    
    The true understanding of logical positivism, is the intimate
    personal experience of having carefully reviewed hundreds of
    doctrines, theories and speculations, and having drawn from this an
    intimate familiarity with the empirical observation of a strong
    general correlation between failures of verifiability/falsifiability
    of claims (in principle and/or in practice), and failures of
    meaningfulness of the terms in which these claims are expressed.
    
    This may not imply any absolute or necessary equivalence between
    both. After all, so many rules have exceptions. But, it means that
    it is healthy to keep an alarm signal ready to ring whenever some
    claims depart from verifiability concerns, so as to remember the
    need to take great care to check the meaningfulness status of claims
    in this circumstance, because experience shows that a lot of
    research efforts went astray due to failures to consider this
    warning seriously.
    
    Let me just give two examples below, and with this disclaimer : are
    they representative of the general case ? Well, how could they ? You
    cannot explain biodiversity by showing 2 animals or 2 plants as
    representative examples. Every example is different. The real point
    is that there is a wide diversity of them, but it is not possible to
    account for this in a few paragraphs. Everyone is responsible for
    one's own intellectual adventures.
    
    First example: the claim "There is no available evidence for the
    supernatural" which I discussed here in
    details. While this claim naively seems readily falsifiable, and
    even one of the most clearly falsifiable claims in the world, a much
    closer examination leads to seriously question this falsifiability
    assumption. But then, once one gets familiar with the serious
    reasons to question this quality of falsifiability, it happens that
    the same reasons also lead to question the meaningfulness of the
    terms that make up this claim by the same move.
    
    Second example is the simulation theory. It fails to be falsifiable
    for the reason that whatever the laws of physics may look like, it
    is always possible to write down an algorithm to simulate them, so
    as to lose any observable difference between the behavior of the
    universe following those laws, and the outcome of said algorithm.
    Now, the meaningfulness of this theory is highly questionable,
    despite naive appearances. I mean that reasons for the lack of
    meaningfulness of this theory (the lack of meaningful differences
    between the concepts of "real structures" and "simulated
    structures") may be very unobvious but still appear to a good
    thinker, especially after getting familiar with the completeness
    theorem of first-order logic introduced here. Precisely,
    I'd be very curious to see a proponent of the simulation theory give
    a proper account of what they oppose: what it could mean for the
    universe to NOT be a simulation... this negation seems to coincide
    with the so-called thesis of "scientific realism". So, well, indeed,
    I cannot see what "scientific realism" may have to do with science,
    since after careful consideration, both supposedly opposite views of
    "scientific realism" and "simulation hypothesis" seem to me equally
    lacking any clear scientific meaning, any clear concept of what it
    might mean for the one to be true against the other. Especially when
    there is no concept of "physical object" in quantum field theory, to
    which the question of its reality would be applicable.
A link on this topic - a special question about it
    The interpretation problem
    As philosophers like to point out, non-trivial facts of science
    usually do not come naked but require some skills for properly
    interpreting observations. I'm just not convinced that philosophers
    would be well placed to bring the needed skills, which I'd rather
    see as more often, depending on cases, matters of common sense
    (which not all people have), accuracy of thinking (logical
    intuition), or scientific expertise (having a large enough body of
    knowledge in some field).
    About clarifying scientific concepts
    An example of a "philosophical subject" of interest for Jean-Marc
      Lévy-Leblond (if I remember well ; but he is physicst before
    being philosopher) is about noticing that modern theories such as
    relativity and quantum physics, failed to go through a work of
    cleaning up their fundamental concepts and vocabulary to a
    comparable extent as classical physics had succeeded before. So they
    are still often presented inside the language, intuition and even
    mathematical parameters of classical physics. This conflict between
    the modern intended theories and the classical intuitions and
    language still used to expressed them, brings these theories an
    unfortunate reputation of being counter-intuitive.
    
    That's right, but: what's the use of making a philosophy about it ?
    This is not a genuine subject for philosophy. This is just a task
    for science professors to clean up existing knowledge. And this is
    an administrative problem to pay attention to this question, and
    provide incentives to:
    - publish better courses cleaning up each possible subject, once for
    all in the world (or several times, of course, but each time caring
    to do better again than previously);
    - For each subject where such a work was already done by someone in
    the world, take the new view and reform teaching after it.
    
    Unfortunately, while such works exist (as I'm caring myself to do
    some), the education system is so conservative that the necessary
    changes are not done (because professors are usually so busy
    repeating over and over again the same old teachings in boring old
    ways, and are so "the best in their fields", that they have no time
    to seriously care whether a better way might already have been
    produced by somebody else).
    
    But hopefully, in a future time when the cleaning up will have been
    done, what will remain of the philosophy whose thesis was to claim
    that the cleaning up is not done yet ? Rather do the cleaning up,
    than philosophize on its lack.
    About consciousness and animals
    It is really terrifying to see so many philosophy teachers insane
    enough to proclaim that only humans would be conscious while animals
    would not, without even any question, while both science and common
    sense demonstrate the opposite (not to speak about NDEs telling
    about meeting again deceased pets in the beyond).
    About identities
    Once I visited a philosophy course which claimed to prove that no 2
    objects can be identical. However this reasoning was invalid, but to
    find the error there it would be necessary to understand quantum
    physics, and how the mathematical structure of quantum physics
    proves that 2 particles of the same kind are absolutely identical,
    i.e. they do not and cannot have any hidden identity that makes them
    2 different objects. But philosophers cannot understand this,
    because they're not good mathematicians, thus can't follow the
    proof. Instead they'll keep their strong faith that such a proof is
    impossible because they believe their little reasoning to be
    correct... So official philosophy keeps presenting and claiming the
    correctness of some arguments, long after they were refuted by
    quantum physics.
    Discussion on determinism
    Once I saw a seminar on determinism. The possibility/impossibility
    of determinism or indeterminism...
    The whole discussion consisted in exploring some kind of range of
    theoretically possible universes. i.e. laws of evolution to wonder
    if they can be deterministic or indeterministic... after which I had
    a little attempt to discuss with him and other present
    philosophers... 
    Seriously, where did that approach of the "range of possible
    universes" come from, if not from pure blind prejudice ? Where is
    the justification why we should accept that it even makes any sense
    to regard these presumed "possible universes" as possibilities at
    all, not to speak about why exclude the possibility of further
    possibilities beyond that given range ?
    Of particular interest in this "range of possibilities", was a class
    of differential equations like those of classical physics. So some
    partial descriptions of phenomena that could be expressed in the
    19th century was in this "range of possibilities", as well as a kind
    of invocation of statistical thermodynamics in a kind of reference,
    again, to its 19th century understanding (and there was no room for
    discussion or possible mutual understanding as their view of seemed
    to be fixed, as non-physicists at ease in their absolute confidence
    to perfectly understand this 19th century baby attempt to approach
    thermodynamics, while I cared
      to clarify the topic on a modern basis).
    But at no point of the discussion did the speaker ever seem
    interested in the question whether modern physics, i.e.
    quantum physics, that is the kind of laws of physics which was
    scientifically found to be the case or at least somehow closer to
    the truth than his 19th century example, could be found to actually
    fall anywhere in his a priori "range of possibilities". Problem :
    how the *** could I take seriously a reasoning based on some a
    priori "range of possibilities" where our particular universe does
    not seem able to fit ?
    Compatibilism
    What a crap ! sounds like "1=1 and 1≠1 do not contradict each
    other". And it is reported to be very popular among philosophers !
    This "solution" to how humans could have free will if the universe
    was deterministic (which is known to not be the case) consists in
    redefining "free will" into... nothing that makes any sense,
    actually.
    Ignorance of quantum physics, again
    Quote from Quantum
      Mechanics and the Hard Problem by Lennart Warnemyr
    When I studied Philosophy of mind by Kim (2011)
        during an introductory course in Philosophy of Mind I was struck
        by how classical Kim’s view of the physical was. He wrote things
        like “mere configurations and motions [...] of material
        particles, atoms and molecules” , “bits of matter” and “the gray
        matter of your brain”. Kim mentions non-classical concepts like
        “electrons [...] quarks, [...] spin”, but he never uses them as
        they are used in the theory they belong to and thus treats them
        as classical physical concepts. 
    A famous philosopher : Wittgenstein
    I once happened to visit a university course of philosophy, the
    teacher was presenting some views which, he said, he took from
    Wittgenstein, who he agrees with. And what was the claim ? It
    essentially meant that there does not exist such a science as
    mathematics with any open problems, since by nature, all
    mathematical propositions are tautologies (mere ridiculously useless
    combinations, or rather repetitions, of the same trivialities).
    Well, my question is : why would people believing such idiocies be
    worth the care to explain why they are wrong ? Just have a look at
      Godel's speedup theorem, for example, and more generally, all
    known facts about incompleteness such as Chaitin's work on
    randomness in mathematics... during that course I tried to mention
    Godel's incompleteness theorem as an illustration of the falsity of
    this philosophy. He dismissed my point, claiming to know the topic
    and denying that any point could be made there (the discussion was
    too short to enter any detail) so that the conversation ended
    without any common understanding. It turns out to be a well-known
    fact that Wittgenstein
      himself never understood the incompleteness theorem. A
      discussion about it.
    Another example of what I see as a logically necessary but quite
    non-trivial fact : Communism
    Cannot Work. Both this logical fact and its non-obviousness had some
    concrete consequences...
    See also the testimony
      of how his attitude has nothing to do with reason.
    Apart from this, well, it can be true indeed as he denounced, that
    many people commit the error of trying to speak the unspeakable in
    such a way that it is not going anywhere. Nevertheless the problem
    is not that there is any well-defined absolute limit to
    expressibilility. I don't see one. Rather, what I generally see in
    the world is a lack of imagination in the people's thoughts and use
    of language to express any wise and interesting ideas. Because not
    only the pure language of maths is already able to express a lot of
    things, the ordinary use of language being not strictly
    mathematical, remains open to the possibility of stimulating diverse
    thoughts beyond pure maths, thus escaping any well-defined boundary.
    Here I mean not only the possibility to tell lots of sterile
    bullshit as so often happens, but also, eventually, to develop high
    intelligent thoughts as well. I experienced this myself as I found
    some non-standard ways of using ordinary language to explain things
    in diverse texts...
    Postmodernism and "science studies"
    A community of ideological flaws can be seen between Marxism, which
    dismisses its opposing theories (economic liberalism) as a mere
    matter of social forces rather than of truth (so as to use ad
    hominem as an excuse to not bother arguing rationally), and the
    postmodernist "science studies".
    
    Everyone should know about the Sokal affair, an episode of the Science Wars:
    "The physicist Alan Sokal
        submitted the article “Transgressing the Boundaries: Towards a
        Transformative Hermeneutics of Quantum Gravity” proposing that
        quantum gravity is a linguistic and social construct and that
        quantum physics supports postmodernist criticisms of scientific
        objectivity. Social Text published the article in the
        Spring/Summer “Science Wars” issue in May 1996. Later, in the
        May 1996 issue of Lingua Franca, in the article “A Physicist
        Experiments With Cultural Studies”, Prof. Sokal exposed his
        parody-article, “Transgressing the Boundaries” as an experiment
        testing the intellectual rigor of an academic journal that would
        “publish an article liberally salted with nonsense if (a) it
        sounded good and (b) it flattered the editors’ ideological
        preconceptions”
    
    However Sokal's hoax should not be overestimated, as it was only
    directed to a precise movement (postmodernism) that should not be
    confused with the whole of philosophy or social sciences: in this
      interview Alan Sokal said:
    
    "I should make clear that I don’t
        think my parody article settles anything. It doesn’t by itself
        prove much – that one journal was sloppy. So it wasn’t the
        parody itself that proved it, it was the things that I and other
        people wrote afterward which I believe showed the sloppiness of
        the philosophy that a lot of postmodernist literary theory types
        were writing. But again, I wasn’t the first person to make those
        criticisms. It was only after the fact that I went back into the
        literature and found philosophers had made many of these
        criticisms long before me. All I did in a certain sense was to
        find a better public relations method than they did."
    
    But he also expresses his skepticism on the possibility for
    philosophy of science to fulfill its goal of understanding the
    scientific method:
    
    "So I guess you’re right that I’m
        skeptical that there can ever be a complete over-arching theory
        simply because science is about rationality; rationality is
        always adaptation to unforeseen circumstances – how can you
        possibly codify that? But that doesn’t mean philosophy of
        science is useless, because all of these attempts that have
        failed as final codifications of scientific method nevertheless
        contributed something."
    
    Anti-Science
      Phenomenon
    "Practitioners of the social
        sciences have not learned, in their own disciplines, much that
        is operationally indisputable, readily reproducible, and
        internationally agreed to; so they cannot easily conceive such a
        thing to be possible in any field. Knowing in their own
        discipline that ideology governs "knowledge" as well as theory,
        they presume that must be so in all fields."
    
    
    Also, the end of the above quoted Weinberg's chapter "against
    philosophy" tells about the relations between science and
    "science studies" by sociologists.
    Some interesting observations are without problem: 
    
    "For instance, Sharon Traweek has
        spent years with elementary particle experimentalists at both
        the Stanford Linear Accelerator Center and the KEK Laboratory in
        Japan and has described what she had seen from the perspective
        of an anthropologist. This kind of big science is a natural
        topic for anthropologists and sociologists, because scientists
        belong to an anarchic tradition that prizes individual
        initiative, and yet they find in today's experiments that they
        have to work together in teams of hundreds. As a theorist I have
        not worked in such a team, but many of her observations seem to
        me to have the ring of truth, as for instance: The physicists
        see themselves as an elite whose membership is determined solely
        by scientific merit. The assumption is that everyone has a fair
        start. This is underscored by the rigorously informal dress
        code, the similarity of their offices, and the "first naming"
        practices in the community. Competitive individualism is
        considered both just and effective: the hierarchy is seen as a
        meritocracy which produces fine physics. American physicists,
        however, emphasize that science is not democratic: decisions
        about scientific purposes should not be made by majority rule
        within the community, nor should there be equal access to a
        lab's resources. On both these issues, most Japanese physicists
        assume the opposite."
    
    
    But other aspects present a strong opposition:
    "It
        is simply a logical fallacy to go from the observation that
        science is a social process to the conclusion that the final
        product, our scientific theories, is what it is because of the
        social and historical forces acting in this process. A party of
        mountain climbers may argue over the best path to the peak, and
        these arguments may be conditioned by the history and social
        structure of the expedition, but in the end either they find a
        good path to the peak or they do not, and when they get there
        they know it. (No one would give a book about mountain climbing
        the title Constructing Everest.) I cannot prove that science is
        like this, but everything in my experience as a scientist
        convinces me that it is. The "negotiations" over changes in
        scientific theory go on and on, with scientists changing their
        minds again and again in response to calculations and
        experiments, until finally one view or another bears an
        unmistakable mark of objective success. It certainly feels to me
        that we are discovering something real in physics, something
        that is what it is without any regard to the social or
        historical conditions that allowed us to discover it.
    Where then does
      this radical attack on the objectivity of scientific knowledge
      come from? One source I think is the old bugbear of positivism,
      this time applied to the study of science itself. If one refuses
      to talk about anything that is not directly observed, then quantum
      field theories or principles of symmetry or more generally laws of
      nature cannot be taken seriously. What philosophers and
      sociologists and anthropologists can study is the actual behavior
      of real scientists, and this behavior never follows any simple
      description in terms of rules of inference. But scientists have
      the direct experience of scientific theories as desired yet
      elusive goals, and they become convinced of the reality of these
      theories.
    There may be another motivation for
        the attack on the realism and objectivity of science, one that
        is less high-minded. Imagine if you will an anthropologist who
        studies the cargo cult on a Pacific island. The islanders
        believe that they can bring back the cargo aircraft that made
        them prosperous during World War II by building wooden
        structures that imitate radar and radio antennas. It is only
        human nature that this anthropologist and other sociologists and
        anthropologists in similar circumstances would feel a frisson of
        superiority, because they know as their subjects do not that
        there is no objective reality to these beliefs—no cargo-laden
        C-47 will ever be attracted by the wooden radars. Would it be
        surprising if, when anthropologists and sociologists turned
        their attention to studying the work of scientists, they tried
        to recapture that delicious sense of superiority by denying the
        objective reality of the scientists' discoveries?
        Relativism is only one aspect of a wider, radical, attack on
        science itself. (...) These radical critics of science seem to
        be having little or no effect on the scientists themselves. I do
        not know of any working scientist who takes them seriously."
    
    A delicious self-criticism article by Bruno Latour : "Why
      Has Critique Run out of Steam" (archived
      pdf - beginning + references in web
      archive), questioning the field of social studies he created
    himself, considering how it turned out to lead to conspirationism,
    denialism, and endangering our planet by the way it is used by
    political lobbies for denying scientific evidence on global warming:
    
    "...I myself have spent sometimes
        in the past trying to show the "lack of scientific certainty"
        inherent in the construction of facts. I too made it a "primary
        issue." But I did not exactly aim at fooling the public by
        obscuring the certainty of a closed argument–or did I? After
        all, I have been accused of just that sin. Still, I'd like to
        believe that, on the contrary, I intended to emancipate the
        public from a prematurely naturalized objectified fact. Was I
        foolishly mistaken? Have things changed so fast?
        In which case the danger would no longer be coming from an
        excessive confidence in ideological arguments posturing as
        matters of fact–as we have learned to combat so efficiently in
        the past–but from an excessive distrust of good matters of fact
        disguised as bad ideological biases! While we spent years trying
        to detect the real prejudices hidden behind the appearance of
        objective statements, do we have now to reveal the real
        objective and incontrovertible facts hidden behind the illusion
        of prejudices?

    Pathological absolutizing as a substitute for clarity, and some
      other bullshit
    Copy of discussion
      in youtube comments
    
      [me] There is little sense to try defending philosophy "in the
      void", not knowing what can be the opposite view.(...) An
      important dimension of the problem you missed, is : can philosophy
      as it now stands, help someone to not tell some terrible nonsense
      in guise of argument ? I see Dave Yount defeated his own side in
      his article by committing this:
      "Here is a smattering of questions that remain to be answered
        or are still debated these days in disciplines other than
        philosophy: (...) Physics: What light exactly is (both a wave
        and a photon) and the essence of gravity;"
      No, this is not an open physics problem anymore since the
      discovery of quantum physics ! only a problem with popularization.
       [PhilosophyVajda] Thanks for your comment. I disagree about
        there being little sense in defending. This video is for an
        introductory course in philosophy. Most students need help with
        basic reasoning and argumentation. One skill I want my students
        to acquire is the ability to better navigate the common
        situation, when one's opponent does not make their own view
        clear and defend it well. The hope is that we can do a good job
        of reconstructing plausible (perhaps strong!) arguments on
        behalf of the opponent. It is a valuable skill to acquire: I
        need to understand my opponent's view, even if they can't
        articulate it well. This allows me to spot errors in my
        reasoning by considering legitimate objections. But it is also
        useful socially. Your opponent might not be articulate, and may
        get frustrated with debate. One way to help them is by
        identifying their reasoning better than they can. This is one of
        the first steps in steel-manning opponents, rather than (the
        tendency) to straw-man. Of course, we can look at more
        opponents. Many who would benefit from this lecture are just out
        of highschool.
        That said, your critique of Yount may have merit in making
        claims where one is not sufficiently qualified. My presentation
        of an author is not an endorsement of that author. Same goes for
        most any of my videos. But even so, Yount's point illustrative,
        even if it is not correct. One can find a functionally
        equivalent one (surely you can give an open question in
        physics?), and it would do the job in supporting his point.
        Would it not? 
      [me] No. Philosophy is supposed to be an art of thinking well
        and not telling too much bullshit. I do not see what else its
        goal might be. And I do not see a better way to argue for its
        success by showing how, as a philosopher, you actually succeed
        in not telling too much bullshit when you discuss something. The
        article of Yount failed at that on one of its very few aspects
        which can be readily and objectively checked. Did you notice
        this error yourself before I pointed this out ? Second, you put
        forward the idea that a given kind of modification would fix the
        point. Is that a good idea you have ? Well, still no. This
        illustrates another widespread flaw of philosophical thinking :
        the inability to think otherwise than in caricatural absolutes.
        The usual philosophical way of thinking about anything is : "Is
        this 100% white ? We can't be sure. So is this 100% black then ?
        well, we can't be sure of that either. So we cannot know
        anything about it then". That's all. So, the article of yount
        considers the stupidly absolutist claim : "Someone might say
        that philosophy is only concerned with questions that no one can
        answer". Well I don't know where is this claim from.
        Nevertheless, a big difference between physics and philosophy is
        that physics could solve over 99% of its problems, which are
        hugely high-skilled, while philosophy could solve less than 1%
        of its own, which are often ridiculously childish and/or
        nonsensical. And the main report I could see of a claimed
        "solved philosophical problem", was that it was so claimed only
        based on a growing consensus instead of genuine evidence, and
        this consensus was to the stupid incorrect answer (the supposed
        refutation of dualism). That big difference between >99% and
        <1% is all what matters to someone who can think sanely
        instead of philosophically, instead of an absolutist version of
        the question (whether an open problem exists in physics, and
        whether a solvable problem exists in philosophy). Of course
        unsolved physics problems still exist, so what ? Moreover, the
        argument of the article said "But there are myriad research
        projects going on in ... physics..." as if it implied something
        about the existence of open problems. It does not. First, in
        physics there are not myriads of research projects, there is
        mainly just one, that is the LHC, and it only succeeded to
        confirm at a high price what was conjectured long ago. Second,
        if there are research projects in physics it does not mean that
        there are open problems, only that there happened to be
        physicists hired for life in institutions and who desperately
        need to justify their jobs, so they need to make up some story
        of a research project. More comments.
      
    
The story of how philosophy happened to dismiss logical positivism,
    is another example of effect of pathological absolutizing, or straw
    man argument : misinterpreting an idea in caricatural ways to end up
    finding flaws in this caricature, then throwing the baby with the
    bathwater. Related article : Politically
        correct fanatics by Winston Wu.
    
    On the philosophy of logic
    Here is my answer to the request for feedback on this video,
      which probably reflects well enough the general view of
      philosophers about logic.
    
      You appear to misrepresent concept of "truth" as ideally
        something uniform, unique and universal, not well distinguished
        from the concept of omniscience, unreachable since it only
        belongs to God by definition; as something too abstract and
        general to, well, be applicable to any particular case. To this
        I'd oppose a view of truth as diverse with respect to the
        diversity of questions one may decide to investigate. There are
        easy questions, for which an absolute truth can be reliably
        reached. There are hard questions for which the answer or its
        proof may be inaccessible, yet or never. There are also
        ill-posed questions, either due to mistakes from the questioner,
        or because reality has qualitative aspects which escape the
        possibility of clear formal expression.
        Looking for a pure ideal concept of "logic", the one such limit
        I know is mathematical logic, that is essentially, pure math in
        general. This is a kind of reality field, with its range of
        questions, which (I think) only forms a part of reality, while
        more of reality may be approximated by it and thus analyzed by
        its tools with more or less success, and still more can't. That
        is a diversity of aspects of reality, which does not imply any
        room for controversy (so-called controversies seem to rather
        result from temptations to mistake one field of investigation
        with another, and misapply tools beyond their scope of
        relevance).
        Like many other philosophers, you seem obsessed with the
        question of whether someone reaches "absolute truth", as if that
        phrase meant something. Like probably the rest of scientists, I
        just don't see the sense of such a mythological concern. Healthy
        climbing sportsmen don't spend their life being upset that they
        are not standing on the tip of Mount Everest. The same goes for
        scientists with their search for truth. "Scientific realism"
        seems to me just a buzzword in the mouth of philosophers, and
        finally an oxymoron, since science rather works along the lines
        of logical positivism which dismisses the question of realism as
        nonsense.
      
    
    More notes
    
    After reviewing some of the existing philosophical papers on the
      growing block time theory (especially those from 2017 to 2021 from
      this
        list and both articles and both videos by Vincent
        Grandjean in Collège de France), I wrote the following
      (written in 2021; added here in 2022):
    
    The paradox of the heap
    I saw this "paradox" in the list of Vincent
Grandjean's
        paradoxes seminar. I also saw a version of it, presented as
      a case of "indetermination" of (the answer to a given question
      about) the future, in one of his articles about time. Whenever I
      see any philosopher mention this "paradox" as if it was anything
      serious, this seems to me so ridiculous, and a symptom of a more
      general thinking flaw typical of the academic philosophers
      community; explanations on this will then be used to explain some
      deep aspects of the contrast of approaches to the growing bloc
      theory of time.
    
     So, what is this thinking flaw. Caricaturally let me describe it
      by qualifying a philosopher as the opposite of a physicist :
    
      - A physicist is a master in the art of making and
        understanding, better than the common man, relevant
        approximations in order to get some numerical results about a
        given physical problem, correctly within a given desired margin
        of accuracy ;
- A philosopher, on the other hand, is a master in the art of
        artificially failing to understand the practices of
        approximations which the common man, so often (though not always
        of course), has great successes with.
Indeed, among the common man's practices of approximations, is
      the possible use of the word "heap" to describe something which he
      may need to speak about. However, like many other words and
      phrases used by the common man, this belongs to the language of
      approximation, which the philosopher seems to have big troubles
      with, as he visibly, quite often, keeps desperately searching for
      clear and rigorous meanings to all such words and possibly
      utterable propositions made out of them (as well as the possible
      words and propositions expressed by diverse scientists across
      their respective fields of investigation, whose useful technical
      languages sometimes keep a similar kind of fuzziness to that found
      in the language of the common man). So, the philosopher has
      problems with the use of the word "heap" which he fails to
      understand. He may, for example, put forward the complaint that
      the word "heaps" is lacking a precise definition, and try to play
      with this word to form with it some weird sentences and kinds of
      story-telling so as to test the limits of its meaningfulness, just
      like children may like to play putting things together in ways
      they were not designed for, curious of what will come out of that
      ; with the difference that, unlike children usually aware that
      they are just playing, philosophers often mistake their own games
      as if these could be a serious and productive form of
      investigation on the nature of reality.
      Now of course, the "paradox of the heap" has its clear and obvious
      solution, or rather, a natural reason why it never was a paradox
      in the first place, and which academic philosophers might be the
      only kind of people on Earth ignorant about; but which therefore I
      am now feeling ridiculously obliged to write down in case some
      academic philosopher reading this page would need it:
    
      - In the case when a common man happens to utter a sentence
        using the name "heap" in it, this usually means that, when he
        undertook to utter this sentence, he decided to do it this way
        because he happened to perceive this word as clear enough to be
        inserted that way in his sentence so as to be well enough
        understood by his intended listener(s) for his given purpose. In
        this case, therefore, it usually does not belong to the
        legitimate role of the philosopher to challenge the grounds and
        relevance of this decision, except of course in these special
        cases when, just like any ordinary listener, he would happen to
        really need some higher degree of accuracy of information than
        he perceives to have got from the given sentence, for any action
        or understanding aimed in the given context. In such an
        exceptional case, then, the listener may have (or not) the
        chance to react at this feeling of ambiguity by questioning the
        speaker, which drives the story to some equivalent of the
        following opposite case : 
 
- In the opposite case, then, of a common man having something
        to say, for which, during some fraction of a second, he may have
        considered the relevance of using the word "heap" as a part of
        his sentence, but then felt this option as unsatisfactory to
        convey to his sentence the desired level of accuracy to be well
        enough understood by his listeners for the given purpose, it is
        then up to him to very quickly undertake a comparison of
        relevance of this option against competing other possibilities,
        such as the possibilities to replace the word "heap" by phrases
        like "big heap", "small heap" and so on, up to any more complex
        detailed explanations, to finally try to select from there some
        hopefully optimal compromise between the needs of clarity and
        those of saving time and effort from explanatory works.
So, this was the clearly satisfactory, ultimate explanation of what
    the word "heap" really means, resolving for all practical purposes
    any "paradoxes" which philosophers could find in it. And the
    ultimate meaning of so many other words and phrases which
    philosophers could have troubles with can be also explained to them
    in the same manner.
    Improper future tense semantics
    Once so clarified this case of the "heap" which, I hope, could be
    seen rather simple (though it might still depend), we may hopefully
    be better equipped to address the slightly more subtle problem of
    trying to decipher the behavior of the common man who may happen to
    utter claims (predictions) about the future, and even to possibly
    utter some meta-claims about such claims, such as the claim that
    some sentence X "about the future" would be clear and meaningful, or
    claims that someone who previously made a given prediction "was
    right" or "was wrong" at the time that prediction was made,
    depending on whether the unfolding facts turned out to confirm or
    infirm the validity of that prediction.
    Indeed, I see natural to classify such claims as essentially similar
    to claims about "heaps", namely, that the whole role of such
    sentences, simply and satisfactorily, is to serve as convenient
    tools in the practice of approximative communication. Therefore, any
    elaborate attempt by the philosopher to take such sentences on
      word by trying to systematically analyze them, may this be in
    terms of a logical system, or a clear semantics of any kind,
    would be, purely and simply, a misunderstanding.
    Any ponderings on the kind of questions which may be relevant
    instead about such sentences, then, namely questions about their
    usefulness in given contexts so as to convey to their listeners some
    intended kinds of ideas and understandings while avoiding any
    wasteful cost of additional efforts that would be involved by trying
    to convey the same useful ideas by other means, will be here left as
    an exercise for the interested reader.
    
    That was to answer the kind of wish (motivation) to make sense of
    claims about the future as expressed by Vincent Grandjean, namely,
    to fit with the common people's uses better than they themselves
    really meant. However there are other, more metaphysically serious
    discussions on the topic, which I will address.
    The source of mistakes
    Now will be a tentative explanation about where philosophers come
    from and what could lead them so astray into this kind of mistakes.
    Philosophers are people in research. They are not the only beings
      in research, though. Other people and even animals are also, quite
      often, beings in research. Now of course, there are differences. A
      first difference is that, while animals, for example, are usually
      searching for food for their stomach, philosophers are often
      rather searching for food for their mind. But the difference of
      concern, here, is that the latter appear quite less successful in
      their research than the former. Now if we focused on reviewing the
      philosophers research (as they did themselves of course... with
      even too much focus, I would say, to have any new chance of success) it could look hard
      to figure out where their failures come from, and more
      interestingly, how it might be possible to do much better. But
      some insights can be pointed out by checking the other side of
      this comparison : where the frequent success of animals and people
      in the search for food for the stomach comes from.
    So, how can animals and people so often succeed in their research
      ? Well, mainly based on their rich experience of previous success
      in the same research. They know how to find food because they
      already succeeded to find food before and they remember. Children
      learn how to find food as they are taught by their parents who
      know. Young animals also naturally find easily, guided for this by
      their genome which somehow represents an heritage of millions of
      years of experience of the same success.
    Now, what are philosophers searching for ? They are searching for
      new knowledge. Some deeper insights on life and the nature of
      reality than they ever heard anyone discovering before. Plain and
      simple, they just don't know what they are really searching for.
      Because, well, if only they already knew what this knowledge on
      the deeper nature of reality, which they are searching for, really
      is, then... by definition, their search would already be over. But
      since they don't know what they are searching for, how could they
      better know how to effectively search for it ?
    Consider another example : the police searching for a criminal.
      As they know very well, their search can be very difficult as long
      as they don't know what the criminal who they are searching for,
      looks like ; but it suddenly becomes easier once they got,
      hopefully a picture, or at least a robot portrait of him. But, how
      can they get such a robot portrait ? If they simply tried to draw
      a portrait themselves out of their imagination, based on their
      guesses of what a criminal doing some given crimes should look
      like, their chances to draw it correctly would be very small; now,
      hopefully, they are usually aware of this, which is why they do
      not proceed in this way. Instead, the only way is to have the
      testimony of someone who actually saw this person, and remembers
      what he looked like. Also, we need good reasons to trust that the
      given witness had a clear vision and memory, and also that it was
      indeed a vision of the criminal searched for, rather than of
      anyone else who might have been on the crime scene by accident.
    What about a similar risk with food : how can people and animals
      distinguish good food from anything which might look pretty but
      which would not be food ? It takes not only an experience of
      finding things before, as examples to follow, but also the
      condition that the things so found were confirmed to be good food,
      rather than misleading experiences of having found things that
      looked nice but were actually not proper food. Fortunately, this
      risk is usually avoided for a clear and powerful reason : if
      anyone once tried to feed himself with anything else than proper
      food, he would have quickly got sick, which would have probably
      forced him to recognize his mistake, and from there, no more eat
      the same another time. Or anyway if he still didn't, and also if
      any other people had been tempted to follow for any long time his
      bad example, then by the force of things such people would have
      probably not survived, so that, sooner or later, such a practice
      would have got an end anyway.
    Back to the case of philosophers. Disclaimer : I am not a historian
    of philosophy. I am thus not claiming to be faithful to any
    chronological order, but I will just use time metaphorically for
    what I only mean as an abstract, conceptual order.
    So, they were searching for some deeper understanding of stuff
      than the common man. Then by lack of having ever effectively found
      such a thing, they tried to focus their research by putting their
      imagination at work to imagine some robot portraits of what such a
      deeper understanding might look like. So, they first undertook to
      give it a name : they decided to call this "the essence" of
      things; and, in case such an essence of a given thing would not be
      unique, it might become different attributes : after all, it would
      be nice for a concept of "essence" to also take the job of
      explaining what makes things differ from each other, so that, for
      this, we probably need a multiplicity of essences as well.
      Therefore, it could look like, we may need to research multiple
      qualities or properties which would be "essential" to these
      things. 
    Now, once having got a pretty name "essence" for the concepts we are
    searching for, also declined in the form of an adjective "to be
    essential" for properties to qualify things, something more was
    lacking : some definitions for what these special words could
    actually mean. Then, whole philosophical theories have been
    developed to offer candidate definitions for these words. Doing so,
    they seemed to neglect that this is not the usual way known to be
    successful how to develop concepts and names, which usually starts
    with a familiarity with the examples, before developing an intuitive
    understanding and description (way of classifying things into given
    kinds, which will serve as their intuitive definitions), after which
    a name is given to refer to these already clear concepts and
    definitions with their known ranges of examples. Admittedly, this
    usual method to coin names and concepts does not ensure these
    concepts to have absolutely clear sense in the foundations of
    reality; but that is not its purpose anyway... and philosophers seem
    to be the only people in the room to strangely forget this
    sometimes. But this should anyway warn us that a great deal of care
    is needed when trying to proceed the creation of concepts in a
    different way. 
    Indeed, philosophers still had no examples for what could be
      "essences" and "essential properties" of things (since they still
      had no specially deep insights into reality). They only had some
      more precise expectations of what these should look like. And...
      no real way to check for sure that these more precise expectations
      could really match the mysterious ultimate target of their
      research.
      Later, a horrible news came and filled the philosophical community
      with dismay: their dear definition of what "essences" or
      "essential" meant, which had been taught to generations of
      students, turned out to not
be
        possibly the right one, since some ridiculous stuff was
      finally discovered to fit into this definition without possibly
      looking like their originally intended target, which this
      definition was meant to describe.
    
    Now, we can observe that this mistake with the words "essence"
      and "essential" is of the same kind as with with the word "heap" :
      a baseless expectation for words and sentences to make clearer and
      deeper sense than they were initially meant to. Some words and
      concepts from common language like "heap", and the "concrete" vs.
      "abstract" distinction, because they were designed and selected by
      experience to work for a fuzzy kind of semantics only ; some
      additional words introduced by philosophers for their own
      purposes, because, beyond pious wishes, these words like "essence"
      have never been properly designed to mean anything at all, i.e.
      may turn out to belong to the same category as what formerly
      respected names like "Zeus" or "phlogiston" are now generally
      recognized to be in.
      So, what happened: starting with a world where the language and
      concepts did not appear clear, they dreamed of a better world
      where language and concepts would be much clearer and deeper. But
      they did not know how to get there, so all they could find to try
      was to dream themselves there, and voila. They did not make any
      big and serious trip which could be effective to reach their
      destination, or possibly they tried to, and might even have put a
      lot of energy in there, but by lack of a good compass to reliably
      give them the right direction in doing so, they did not really
      succeed going anywhere worth it.
    
    Simply, there is a direct contradiction in this combination of
      attitudes or expectations which seem widespread in philosophy : to
      mainly keep the same language, concepts and basic experiences as
      the common man, and to directly and correctly give this
      all a much clearer and deeper semantics than the one known to fit.
      Indeed, if any deeper layer of reality is to be identified, then,
      at least, it should have a significant deal of differences from
      our usual one, so that any proper translation and explanation of
      the usual reality in terms of a deeper one, should require a deal
      of translation work, which would turn our familiar stuff into a
      more complex form than the form of its basic appearance. Such a
      complexity would be quite heavy to work with, if we tried to
      describe a lot of familiar stuff through such lenses. Since
      philosophers would anyway not have enough energy for such a task
      (ifever they had a clue how to do it right), one should admit that
      any reasonable hope of expressibility (to not mention
      discoverability) of a proper solution in any manageable amount of
      efforts, will at least require to discard a lot of our "familiar
      reality" and language, as out of subject. A condition which they
      seem traditionally far from being ready for. But, yes, I
      understand, in lack of a good compass to tell where to go, the
      mere request to go a long way would not have sufficed anyway.
    
    Metaphysics in free fall
    
    "Traditionally, quantum entities were thought to be
      indiscernible: two quantum entities share every property and every
      relation. That leads directly to a violation of the Principle of
      the Identity of Indiscernibles (PII) in quantum mechanics. The
      violation of PII, on its turn, leads immediately to two distinct
      possibilities on what concerns the metaphysical status of its
      entities: they are either non-individuals (i.e., entities without
      identity conditions) or else they are indiscernible individuals;
      that is, entities individuated by some Transcendental Principle of
      Individuality (TI), like bare particulars, primitive thisnesses,
      haecceities and the like (see French and Krause 2006, chap. 4).
      That much seems to be uncontroversial in the traditional
      metaphysical analyses of quantum entities. Still according to a
      more recent tradition, the fact that we have at least two options
      leads directly to a form of metaphysical underdetermination:
      quantum mechanics provides no hint as to which of the previous
      metaphysical packages should be preferred"

    The Popularity Battle
    Instead of an effective means to test their theories and
      arguments against reality, the main or perhaps only available
      criterion of quality they have, is their convincing ability, i.e.
      popularity, including peer-review, in the eyes of... other
      philosophers. These may be doing their best in trying to assess
      the quality of works from their own viewpoint, but anyway as
      people also ignorant of what the hoped for deeper insights on
      reality would look like... and even often without a strong
      scientific background when that would be needed : reviews by
      genuine scientists are not often at play there, for example. I
      guess even philosophy of science articles are usually reviewed
      mainly by other philosophers, rather than scientists of the
      involved fields. That is how :
    
    - Bohmian
        Mechanics, for example, can enjoy a large popularity among
      philosophers in contrast with its general unpopularity among
      quantum field theorists, whose own insights can be the basis of
      some deep reasons for them to dismiss this theory beyond the
      somewhat naive perspective of philosophers. 
    - Philosophers of physics, or of time theory, often refer to "causal
    set theory" as if it was a physical theory. It isn't. It is just a
    dream, a wish to invent some kind of theory that might someday be
    made compatible with known physics. But we are still far from there.
    There is no good reason to believe that a theory of this kind is
    actually conceivable, and there are good reasons to believe the
    opposite. Namely, it is a kind of synomym of superdeterminism, that
    is a class of theories known as having no possible member. Now if
    someone wants to be serious in referring to science as it now
    stands, rather than losing one's mind into science fiction
    fantasies, one should not refer to "causal sets" as a part of
    physics : it isn't. There are much better reasons to refer to
    parapsychology as a part of science, than to refer to "causal sets"
    as a scientific theory. This may be a side effect of the terrible
    ambiguity of the use of the word "theory" which may be used as well
    to name the most well-established facts, and the most hopeless,
    implausible hunches.
    - Some largely outdated or inaccurate elements from science do
      not seem exceptional among examples or references of philosophical
      articles. 
    
    Examples: the possibility of a Big Crunch ; the confusion between
      
    
    
      - the conflict of the Hidden Variables and Spontaneous collapse
        interpretations of quantum physics with Special Relativity, 
- and the conflict of Quantum Field theory (which is
        relativistic), with our theory of gravitation (General
        Relativity). 
This last mistake is committed around the note 61 of the thesis "Structure
and
        transition: towards an accretivist theory of time"); there
      are genuine speculations that the solutions to both conflicts may
      be linked, but it is another topic. 
    While this relatively unfavorable condition for the development of
    philosophical research could be excused as an external necessity to
    deal with, such an excuse begins to lose validity when the issue of
    popularity of ideas across the philosophical community, moves from
    its basic unfortunate role of the only available compass driving the
    direction of philosophical works as a cause, into also
    taking this role as a target. 
    To be more precise, when strategical concerns towards matters of
    popularity (the word "marketing" would be clearer, just probably too
    strong here) happen to be explicitly stepping into the concepts and
    arguments of philosophical works themselves at the expense of purely
    rational concerns (the main point of Vincent Grandjean: Symmetric
    and asymmetric theories of time), that is starting to look quite
    terrible from a scientist's viewpoint.
    More notes (added later)
     A long quote explaining some of this
    About a traditional ridiculous mistake I see as specific to academic
    philosophy and a few other fields, against common sense : the
    mistake of giving unfounded confidence in tentative strict, literal,
    rational categories where these are inappropriate and not actually
    justified on rational grounds (sorry I can't even qualify as
    rational anyone who goes on publishing or referencing claims of
    rational analysis of something without double-checking their
    appropriateness). I mean I do not see this trouble in hard sciences
    precisely insofar as these focus on specific issues where hard
    rational analysis can find its genuine field of validity. I mean of
    course, for those scientists who are not mistaking their field of
    research as if it was "everything" of reality ; if there are such
    hard scientists mistaking their field of research as if was the
    whole reality, or applying a priori given rational categories
    without proper checking, then I would say it is their personal
    philosophical mistake and not a trouble with hard sciences
    themselves, abstractly taken in their own right.
    
    I found a nice expression of the situation expressed in William
    James' Afterdeath Journal. I mean that is what can be expected from
    a dead philosopher indeed, i.e. someone who had been familiar with
    philosophers fallacies, then could get out and see some of what was
    wrong with this (yet I would not say he sees it all). In his
    description he seems to dismiss all hard rationality as irrelevant,
    but I guess it mainly comes from two factors:
    
      - It sounds like he just recently discovered what it means for
        someone to NOT try to talk about metaphysics, and appears
        somewhat excited about it, but still not everything about it
        seems clear to him just yet. Indeed he appears to keep the
        exclusive obsession towards the topic of metaphysics which is
        typical of philosophers (and for which I may agree that many
        such attempts of rational categorization by philosophers fail)
        as if it was the only topic of interest in life; he does not
        happen to be interested in hard sciences (which is not only
        physics but also mathematics, and other possibilities of
        properly using deep rationality that I will not detail here);
        that is his choice.
- He is concerned with materialist scientists, i.e. skeptics, who may
        be loud in scientific popularization indeed, and some wild
        pseudo-scientific speculations which popularization can also be
        biased for, but I do not consider them representative of science
        or rationality.
 
So here is the quote :
    For while the physical world is operationally
        predictable (and then, only generally speaking), that
        predictability is operative only when inner components of the
        mind act upon physical properties in a certain very precise
        fashion. The physical world must be "turned on." Only then does
        it appear with its predictable elements. Only then do objects
        have reality, flowers grow, seas turn with their tides, and the
        splendid sun's heat warms the land. 
      So far, science has only examined results. By its
        insistence upon the priority and superiority of matter's
        dominance, it ties its own hands. The very focus of its beliefs
        leads it toward an endless categorizing in which it follows
        minute particles into a deepening invisibility. The hypothetical
        discovery of each new minuscule particle exerts an
        ever-deepening hypnotic effect, leading the scientist down a
        road that is self-defeating if he hopes to delve into those
        phenomena that exist beneath the world's operating reality.
      The mind, so entranced by these matters, so led astray,
        itself possesses the abilities to perceive the inner structure
        of life, but in a different fashion. The old methods of
        measurement do not apply to a nonphysical reality; yet the mind
        has its own values, its own methods and measurements, and the
        mind's very existence is its own evidence. To that evidence,
        science remains blind.
      The scientist often says impatiently, "I deal with the true
        or false world. A phenomenon exists or it doesn't. An object is,
        or isn't. I deal with provable facts." This attitude alone shuts
        out from science's province the very unpredictability, the very
        creativity from which the predictable world emerges.
      Modern science rightly rebelled against the excesses,
        exaggerations, and superstitions of religion and against a rigid
        system of beliefs that encouraged man to interpret the natural
        world only in the light of its own dogmas. Yet science went
        overboard to prove itself, adopting many of those authoritative
        characteristics and denying the existence of any phenomenon that
        is not observable according to its own set of limited
        measurements, or that does not agree with its basic theories.
      In whatever erroneous a fashion, however, religion did
        attempt to categorize inner realities, for it numbered its
        "species" with as much vigor and self-righteousness and
        determination as any scientist pinpointing the number and kinds
        of rocks, birds, gases, or particles. The demons, minor gods,
        mythological creatures, hells and heavens were all in their way
        the results of this same kind of specification, misapplied; for
        in the inner reality, such methods are ludicrous.
      Both religion and science seek "truth," but the literal
        interpretation, physical reality is as limiting as the literal
        interpretation of the Bible. There are fundamentalist scientists
        quibbling over whether the universe is forever expanding, or is
        endlessly expanding and contracting—and that is as much an
        exercise in futility as medievals debating how many angels can
        sit on the top of a pin. The attitudes of mind, the childish
        literal interpretations are the same; equally absurd, if the
        greater issue of truth is to be involved. 
      The very definitions of truth are at fault.
      Science and psychology owe their birth to religion's
        failure in conducting that search [for truth]. They are
        split-offs from religion, each with their own methods, yet they
        have to a large extent converged. For all of psychology's stated
        interest in man's subjective nature—held while still maintaining
        its basic objective stance— psychology is de- pending more and
        more upon technology and scientific instruments to measure the
        mind's products and behavior; a new futility also perpetuated
        because of limited concepts and misunderstandings concerning the
        pursuit of truth itself.
      For what does truth mean? In scientific terms, it means a
        provable fact such as "Today is Wednesday" or "An apple is a
        fruit." These facts are operational; one categorizes time, and
        the other, an object. Neither tells us anything about time or
        objects, however.
      In fact, the belief that today, Wednesday, is followed by
        Thursday, while operationally true, also leads to drastic
        misconceptions about the nature of time itself, couching it in
        the consecutive terms of everyday experience. This discrepancy
        goes quite unnoticed when you meet a friend for a Wednesday
        appointment, and the convenient use of time is to be maintained
        in any orderly physical world.
      Scientists know, however, that time is relative, and if the
        dictum "Time is relative" is a fact or truth, then is the fact
        of consecutive time true or false? If false, then no day is
        Wednesday, whether the statement is operationally true or not.
        For that matter, Wednesday does not exist in the same way that
        our apple does. In that regard, the statement that an apple is a
        fruit is the "truer" of the two statements. But even the apple's
        fruitness tells us nothing of the origin of fruits, or explains
        how the apple has fruit rather than animal characteristics; and
        no matter how far you go with this kind of truth finding, you
        will ultimately be led to a point where one fact contradicts
        another, or another framework of facts, or where you simply run
        into ignorance—a point of no answers. 
      The reason is astonishingly simple. The overemphasis upon
        categorization leads to an infinitely larger and ever-increasing
        number of facts, each considered true; and with this
        multiplication, the discrepancies collected along the way also
        multiply. You end up with various disciplines, each with their
        fact-truths, and under examination the facts of one discipline
        too often do not apply to those of another field--a "fact" that
        those in all disciplines often conveniently overlook.
      Within any one school of knowledge these discrepancies are
        invisible, and overall people operate in a fairly predictable
        environment regardless, eating delicious apples and secure in
        the knowledge that each Wednesday is followed by a Thursday. It
        would serve no purpose, either, to say that apples are not
        fruits; a statement that is false if you accept the apple's
        fruitness. But the truth or falsehood of such statements are
        beside the point of basic truth, which should deal with the
        innate nature of time or with the innate nature of objects
        rather than with their specifics. Under what conditions is an
        apple a fruit or a chair a chair? Under what conditions do we
        experience time as Wednesday, or as a series of consecutive
        moments, and under what conditions might time behave elsewise?
        Do any of these phenomena exist independently of our perception
        of them? 
    How academic philosophy is just a religion among others
    Like Christianity and probably many other religions, academic
    philosophy fooled itself by developing and falling into its own
    vocabulary traps.
    
    For example, Christianity uses the phrase "the Word of God" to mean
    the Christian Bible ; "knowing God" to mean having learned the
    Christian doctrine, having faith in it, and practicing prayer ;
    "testimony" to mean someone's personal story of having arbitrarily
    chosen to believe in Jesus without due evidence, and then
    arbitrarily believed this to have meant "knowing Jesus personally"
    no matter how baseless that belief could be, as if any other kind of
    story could not deserve to be seen as an authentic testimony ;
    "mission" to mean going to preach the Gospel, as if no other kind of
    mission could be a legitimate and worthy mission in God's eyes, etc.
    It is by the force of such fallacies that Christians made it
    inconceivable for themselves how anyone could make sense of life and
    fulfill its deepest purpose otherwise than by being Christian and
    dedicating their efforts to their religion. 
    So doing, they completely miss the fact that they are far from the
    only ones, since so many other religions equally lead their
    followers to believe their other religion is the only one that can
    be followed when caring about the sense of life in the right way.
    One of the crucial tools of this delusion consists, for each group,
    in forming its own bubble of collective thought, inside which unanimity
      appears to be reached. They only admit like-minded people
    inside their own bubble, or, even if they are not aware of doing it,
    it automatically happens anyway by nature due to the fact they have
    a specific label under which they believe that proper thinkers
    should join, after which they only consider those people who endorse
    this label, as voices to be counted in the consensus to be formed.
    Then, they use the consensus reached inside it as an implicit
    argument to consider their religion as the necessary conclusion of
    "all serious people", at least in good approximation, and thus
    dismiss as insane, hubristic, extremely insulting and thus not
    deserving any consideration or reply, any view which strongly
    diverges from this "consensus". I have commented elsewhere about the
    deluding sport of humility
      contests and complaints
      against the perceived "insulting" attitude of one's opponent,
    and so I will not repeat here all what still applies here from
    there.
    
    So, the followers of every given religion are usually mainly
    familiar with the arguments for their own specific religion, rather
    than those for another religion, or those against their own; and it
    is based on this context that "everything objectively looks as if"
    this clearly was the one possibly serious religion, and it would
    have to be a conspiracy of God or the universe if reality turned out
    to be otherwise. Now, who would care spending one's time criticizing
    a specific religion, and why ? Few people care for such a dirty
    work, but if someone cared, those targeted by the criticism would
    just wonder what is wrong personally with him, instead of trying to
    understand the actual arguments (which will be hard to understand
    anyway).
    Consider this : if the rest of people are not criticizing your
    religion, but just stay away from it and keep silent about it, then
    this silence is objectively the worst possible insult against it,
    since it means they regard it as not even worth any attention or
    reply. If you really understand this, then you should welcome and
    praise as one of the most respectful and generous acts in the world,
    anyone's devastating criticism against your view, because doing this
    means considering you worth their care to explain to you what a
    really different viewpoint looks like, and why it is that not
    everyone is following you, an explanation which you might waste your
    life missing otherwise. But, things are more often perceived quite
    differently : an attitude of silence and avoidance towards a given
    religion, feels like the polite way (unlike explicit criticism),
    because it is the way to leave the devout members in peace with
    their solipsism. 
    
    Now, academic philosophy is just a religion among others in the
    sense just described : it starts with an abuse of its holy word
    "philosophy" to confuse itself (the study of its specific
    literature) with, well, just the same general care for the sense of
    life which is the obsession of any other religion, making it
    inconceivable for them that anyone else might try to distinguish
    both.
    
    Of course, it has it excuses to "justify" this confusion it makes.
    Namely, it may insist that its own approach would be the
      rational approach to the sense of life, as if this sufficed to
    make it the only valid one.
    You know what ? Every other religion also sees itself as the
      rational approach to the sense of life. And they have their
    own respective excuses to see themselves that way. For example,
    Muslims insist that there would be scientific evidence for the truth
    of Islam... Buddhists or similar teachings like to insist that they
    are not teaching any doctrine but just inviting their followers to
    make their own "scientific research" about the effects of
    meditation... fundamentalists Christians have their "logical proof"
    of the resurrection of Jesus, so that one cannot deserve to be seen
    as a rational thinker unless one devoutly follows and accepts the
    validity of their argument.
    Even if you try to strengthen the requirement in terms of the
    concern for a rational approach so as to exclude most religions,
    this remains unlikely to exclude another competing ideology with its
    different literature and many followers : the so-called "scientific skeptics" (who are not always
    friends with academic philosophy, especially as they usually support
    logical positivism unlike philosophers), claiming to combine the
    authority and reliability of science (which was itself not a real
    threat for philosophy due to the division of topics), with a concern
    for topics close to human life (which philosophy was supposed to be
    the voice of). Now, how do philosophers respond to this challenge ?
    It seems, they often ignore it: unless I missed something, they are
    objectively direct competitors, yet they managed to ignore each
    other just by the magic of using different holy keywords to
    virtually separate their agendas. What I could see from philosophers
    often looks like the story of "skepticism" started with Xenophanes
    and Pyrrho of Elis, and almost ended with Hume. The modern movement
    of scientific skepticism almost did not seem to appear on their
    radar screen, despite its recent huge impact on society as an
    ideological basis of health policies. The concern seems to have been
    more often expressed by the keyword "scientism"... which seems to be
    often confused with experimentalism as opposed to theoretical and
    deductive approaches, a confusion promoted by the "scientific
    skeptics" themselves... but unless I miss something, the arguments
    appeared to be quite superficial; in particular, distinctions
    between scientific skepticism and genuine science may have been
    often overlooked.
     Social observations show the simple and devastating reason why
      the "most rational approach" argument has no weight : who is the
      judge of what is genuinely rational and what isn't ? Anyone can
      always qualify himself as following the "most rational way". Thus,
      as long as philosophers are their own judges, their argument from
      how rational they think they are, remains void.
      This can explain why science and technology could progress, while
      philosophy didn't : science and technology (as well as most fields
      of human work, including arts), have some verdict/feedback
      from an external reality to decide what works and what doesn't,
      what is effectively valid and useful and what isn't; math has its
      rigorous validity criteria; in arts you cannot meaningfully
      dismiss the public as mistaken about whether something is good for
      them or not. These do not remain hopelessly subjective and
      fanciful as happens for philosophy, whose only feedback, that is
      peer-review, can well be completely misguided.
      
      Academic philosophers keep observing and complaining that their
      works are not taken seriously by scientists, but visibly could not
      decipher the real reasons for this fact, since they keep absurdly
      trying to defend their discipline out of the point, never
      questioning their basic ridiculous misuse of the word
      "philosophy", trying to argue that scientists "need philosophy" or
      "are trying to do philosophy anyway", and therefore should need
      the works of philosophers for this reason. No, of course, the
      claim (rather, the ridiculous presupposition) of academic
      philosophers for having their favorite literature being taken as
      the necessary reference for any act of serious thinking and
      exploration on the sense of life or other big questions, is not
      legitimate. However, they keep forever keeping their defense out
      of the point, since maybe scientists did not waste their time
      insisting on the exact terms of the disagreement (or even, some of
      the most visible ones did not provide the proper explanations),
      and anyone who would dare expressing the divergence in the correct
      way would be dismissed as insane, ridiculous, arrogant,
      insulting... and thus not deserve any reply.
    What else ? That scientists would owe something to philosophers
    because historically, science was born from philosophy. Well, humans
    descend from apes also, but this does not mean that apes have
    lessons to teach to humans about how to live.
    
    So, it is possible to express academic philosophy as a specific
    belief or faith like the faith of any religion : the belief that its
    specific literature is, in average, the best available literature
    which anyone needs to study, and will then hold as relevant, to
    properly try to explore the sense of life. Obviously, this statement
    of the philosophers faith, is only believed by less than 0.1% of the
    world's population, and thus rejected by more than 99.9%. Yet this
    definition of the point of the value of philosophy has largely been
    missed, with philosophers focusing on claiming to defend their jobs
    by ruminating trivialities of the form "it is better to try thinking
    about the sense of life than not", just like Christians trying to
    defend their faith by ruminating arguments of the form "it is better
    to follow God's will than not", and remaining clueless about why
    this does not suffice to get the rest of the world to run up and say
    Amen !
    I would even suspect this mistake to be linked with the above
    mentioned mistake of denying the consciousness of animals : a kind
    of confusion between the experience of consciousness and the
    practice of academic philosophy. Indeed how is it possible to
    determine whether animals are conscious if not from the observation
    whether they are able to read and write some philosophical
    literature ? 
    If you ask : if that literature is not the best, then, what can be
    better ? This is out of topic, as the point here is not my own
    suggestions, but the general fact of the unpopularity of the
    philosophers references; different people would bring their own
    references (or a denial of the need to refer to any specific
    literature), and that is what philosophers fail to address. Yet, out
    of topic thus, I would suggest the literature on Near Death
    Experiences (though of course some fraud or nonsense may also exist
    there sometimes such as Eben Alexander and the Urantia book) and the
    channeled books from Jane Roberts. Indeed after a lot disappointment
    and debunking of fallacies from diverse religious teachings I
    happened to find and see these as globally good, though I do not
    mean the study of this specific literature to be necessary either :
    as this literature itself states, there is no necessity to study any
    specific literature at all for finding the sense of life, as the
    experience of life itself with its endless diversity, is its own
    purpose (and it is up to everyone to find the sense of one's own
    life, which may differ from that of others) with no general need of
    doctrinal expression.
    
    One of the worst possible arguments : that academic philosophers
    should be held as the reference because they are the ones having
    jobs in academia, unlike religions. This would be taking things
    upside down. There were times and places (and there still are) where
    theologians of specific religions were the ones having jobs in
    academia, and so they assumed having the right for their respective
    teachings to be held as the truth reference for this reason. Then it
    happened to require bloody revolutions for taxpayers to kick these
    out from their positions and declare
      that "The Republic does not recognize, pay, or subsidize any
    religious sect". Now how much blood may it require to manage
    similarly putting back "philosophy" to its right place ?
