  • What is Dennett’s point against Strawson?
    for whatever reason.Srap Tasmaner

    E.g., possibly: our thinking in symbols.
  • What is Dennett’s point against Strawson?
    That an illusion of consciousness isn't necessarily consciousness.
  • A hybrid philosophy of mind
    If it could happen without “magic”, that would mean it was something that could be built up from non-conscious processes, and so would not be whatever the supposed difference is between a philosophical zombie and a real person.Pfhorrest

    Yes, but it doesn't have to be that specious and spurious difference. It only has to be the difference between an ordinary zombie such as a smart phone and a conscious machine such as one of us.
  • A hybrid philosophy of mind
    Phenomenal consciousness is defined in opposition to that kind of process. Nothing that the ordinary mechanical properties of matter can build up to, including the full complex and nuanced behavior of a human being, can constitute phenomenal consciousness by itself, as it is defined by the people who came up with the idea.Pfhorrest

    Pan-psychists' being wrong about zombies doesn't make them right about pan-psychism.
  • Would it be a good idea to teach young children about philosophy?
    It happens in any non-religious school as "Religious Studies". Which many such schools (sample of one) now call "Philosophy and Ethics".

    Not all matter is wet, even in the slightest degree, but liquids usually are.

    Not all matter is (phenomenally, of course) conscious, even in the slightest degree, but animals able to play a social game of pointing symbols at things usually are.

    some arbitrary line somewhere, the line between things that are held to be entirely without anything at all like phenomenal consciousness and things that suddenly have it in full,Pfhorrest

  • Hume's sceptical argument: valid and sound?
    Conclusion: it's not possible for us to gain or obtain knowledge about anything that goes beyond our senses, memory and testimony.Humelover

    Or is it?...

    But here it may be proper to remark, that though our conclusions from experience carry us beyond our memory and senses, and assure us of matters of fact which happened in the most distant places and most remote ages, yet [...]

    In a word, if we proceed not upon some fact, present to the memory or senses, our reasonings would be merely hypothetical; and however the particular links might be connected with each other, the whole chain of inferences :wink: would have nothing to support it, nor could we ever, by its means, arrive at the knowledge of any real existence.
    — Hume, Enquiry, section 37

    Had not the presence of an object, instantly excited the idea of those objects, commonly conjoined with it, all our knowledge must have been limited to the narrow sphere of our memory and senses; — 44

    Hence likewise the benefit of that experience, acquired by long life and a variety of business and company, in order to instruct us in the principles of human nature, and regulate our future conduct, as well as speculation. By means of this guide, we mount up to the knowledge of men’s inclinations and motives, from their actions, expressions, and even gestures; and again descend to the interpretation of their actions from our knowledge of their motives and inclinations. — 65

  • Midgley vs Dawkins, Nietzsche, Hobbes, Mackie, Rand, Singer...
    The bad science part is to assume that it's simple. For instance, there is probably some genetic basis for character traits, but there's no one-to-one relationship between genes and character traits. "The genes of love" or "the genes of selfishness" are gross simplifications of far more complex realities.Olivier5

    To be fair:

    The bogey of genetic determinism needs to be laid to rest. The discovery of a so-called ‘gay gene’ is as good an opportunity as we'll get to lay it.

    [...]

    Genes, in different aspects of their behaviour, are sometimes like blueprints and sometimes like recipes. It is important to keep the two aspects separate. Genes are digital, textual information, and they retain their hard, textual integrity as they change partners down the generations. Chromosomes — long strings of genes — are formally just like long computer tapes. When a portion of genetic tape is read in a cell, the first thing that happens to the information is that it is translated from one code to another: from the DNA code to a related code that dictates the exact shape of a protein molecule. So far, the gene behaves like a blueprint. There really is a one-to-one mapping between bits of gene and bits of protein, and it really is deterministic.

    It is in the next step of the process — the development of a whole body and its psychological predispositions — that things start to get more complicated and recipe-like. There is seldom a simple one-to-one mapping between particular genes and ‘bits’ of body. Rather, there is a mapping between genes and rates at which processes happen during embryonic development. The eventual effects on bodies and their behaviour are often multifarious and hard to unravel.

    The recipe is a good metaphor but, as an even better one, think of the body as a blanket, suspended from the ceiling by 100,000 rubber bands, all tangled and twisted around one another. The shape of the blanket — the body — is determined by the tensions of all these rubber bands taken together. Some of the rubber bands represent genes, others {105} environmental factors. A change in a particular gene corresponds to a lengthening or shortening of one particular rubber band. But any one rubber band is linked to the blanket only indirectly via countless connections amid the welter of other rubber bands. If you cut one rubber band, or tighten it, there will be a distributed shift in tensions, and the effect on the shape of the blanket will be complex and hard to predict.

    [...]

    So, if you hate homosexuals or love them, if you want to lock them up or ‘cure’ them, your reasons had better have nothing to do with genes.

  • A Nice Derangement of Epitaphs
    A declarative sentence is the standard linguistic device for pointing a word at one or more objects.

    An assertion is the device in operation.

    Why is it hard to tell the difference? Because the operation is a fantasy.

  • A Nice Derangement of Epitaphs
    The creatures dominant on this planet hold a great many beliefs, beyond the findings of their excellent sciences. Perhaps most fundamental, deeper even than religion, is their belief in the reality of their symbol systems, such as language, art, and money. Prowess in such make-believe probably accounts for their dominance. Many other creatures attain sophistication in the conduct of some fairly fixed and innate system of communication, able to convey the location of food sources for example. But they are like Searle's Chinese room: automata. Humans alone seem equipped to entertain what we might call "passing theories" of reference, guessing and second-guessing possible novel (and completely pretended) correlations of symbols with objects: cave floor with tundra, rock with mammoth, pebble with bait, etc.

    In principle, we can imagine creatures able to maintain such theories in an entirely hypothetical mode: second, third and nth degree-guessing. (Lewis.) However, the utility of and need for belief (or suspension of disbelief) in this respect, is easy enough to credit. Shared enough, passing theories thus solidify into "conventions" or "prior theories". Solid enough, they obscure or trivialise the level of semantic skill attained, so that even philosophers are able to catch each other out taking them (and it) too literally or inflexibly.

  • Mathematicism as an alternative to both platonism and nominalism
    A visual map can be encoded in binary on a computer, and a human could read off those ones and zeros, even if they didn’t understand what they were reading. All the information in the picture would be retained in the sound of the human voice.
    — Pfhorrest

    So this seems to me an excellent example of the obvious differences to be found between an object (whatever it was, a still life?) and its representation or description (the vocalised bit map). The map is certainly not the territory.

    If that picture were to be perfectly detailed down to the subatomic level, it would have to be animated
    — Pfhorrest

    If you mean represent temporally successive states, gradients etc. then, sure. If you mean represent them by a temporal succession of symbols, then surely not? Why? (I know the bit map is vocalised as a succession, but thus far that aspect was irrelevant to what it described, and could continue to be so, I would have assumed.)

    or at least include temporal information in it like momentum, and all of the structural details that give a complete picture of its function,
    — Pfhorrest

    Sure, why not. We're on a flight of fancy as regards the level of precision achieved by the description, but that's ok. Bolt on another hard drive (or immortal chanter) to store the whole bit-map.

    and contain within it all the exact information that the physical thing the “picture” it is of does.
    — Pfhorrest

    (Interesting syntax... reminds me of "no head injury is too trivial to be ignored" ;) )

    Do you mean, "the physical thing that the picture is (a picture) of: the thing it depicts; the bowl of fruit?

    Ok, the picture/bit-map/description must be as complex as the physics of a bowl of fruit; but was this paragraph meant to show how the bit-map must become a replica of the bowl of fruit? That's what I'm not getting.
    bongo fury

    Talking about a literal map of a city is probably a clearer illustration.Pfhorrest

    Evidently not. How or why must the ever more elaborate vocal performance which is the bit-map become more and more like the bowl of fruit?

    Yes? When was the last time you saw a yurg?tim wood

    You wrote the puzzle :wink:

    No yurgs are green, or, all yurgs are blue, on the other hand, cannot be presumed to imply there are any yurgs.tim wood

    :up: Cool, e.g.,

    For all choices of x, not yurg without blue. (Could be zero yurgs.)

    you would have them as proof of the existence of yurgs.tim wood

    No, but their negations, yes. E.g.,

    For fewer than all choices of x, not yurg without blue... hence, for some one or more remaining choices of x, yurg without blue.

    ~∀x~(Yx & ~Bx) => ∃x(Yx & ~Bx)

    By the way, though, also the green:

    ~∀x~(Yx & Gx) => ∃x(Yx & Gx)

    Or even just non-yurg:

    ~∀x~(Yx) => ∃x(Yx)

    and

    ~∀x(Yx) => ∃x(~Yx)

    Also of course

    ∀x(Yx) => ∃x(Yx)

    I.e. a universally quantified conditional (just like a universal categorical) needn't imply existence ('import') of the type of object named in the antecedent; but the quantifier itself always refers to the whole universe of assumed entities, and hence always facilitates implication of some existential statement or other.
  • Are you a genius? Try solving this difficult Logic / Critical Reasoning problem
    if the false proposition were that no yurgs were not dinosaurs, then you're in the position of affirming the existence of yurgs.tim wood

    Yes, being asked to deny the non-existence of yurgs of a certain type is being asked to affirm their existence, surely?

    If you are disconcerted by that step, maybe you (like me, often) slipped into thinking the invitation was to deny, instead, some spurious inference to the existence of yurgs of the opposite type?
  • Are you a genius? Try solving this difficult Logic / Critical Reasoning problem


    I was reminded of this (for me) very embarrassing thread when quoting Quine here:

    But the configuration of prefixes '~∀x~' figures so prominently in subsequent developments that it is convenient to adopt a condensed notation for it; the customary one is '∃x', which we may read 'there is something that'.

    bongo fury



    the argument itself does not grant people.tim wood

    Doesn't it at least deny:

    1) ∀x~(Px & ~Dx)

    I.e. for all choices of x, no personhood without dinosaurhood?

    And wouldn't that denial:

    2) ~∀x~(Px & ~Dx)

    i.e. for fewer than all choices of x, no personhood without dinosaurhood

    ... seem to suggest that for some one or more remaining choices of x, personhood without dinosaurhood? ... i.e.,

    ∃x(Px & ~Dx)

    as per Quine's definition?

    Because only whole sentences can be true, whereas only parts of sentences can correspond to reality.

Or is the private language argument no more than a reductio on the hypothesis of qualia? Excuse my irony failure if so.



    et al

    For at least 20 years - confounding my assumption that it would inevitably worsen - I've been able to cure the occasional onset of a "tuning fork" tinnitus within a few seconds, apparently by calling its bluff: listening as carefully as possible to the tone as though it were produced by a musical instrument, comparing it with the rest of real and imagined sound with respect to pitch, volume, tone colour, partials etc. Either by complete coincidence or (I prefer to think) in consequence of a recalibration of the whole auditory system, it stops.

    I've seldom had the courage or presence of mind to withhold the procedure and thus test for coincidence. Too anxious to make it stop. Which is appalling superstition. I must henceforth attain more (haha, even the slightest semblance of) rigour in assessing the effect of the procedure. (But hey, this is the internet, so, take it from me, it really works!)

    But what is recalibration? Not necessarily correction of a mapping of (sets of matching) internals to (sets of matching) externals. (Qualia sets to stimulus sets.) Rather, perhaps, just the matching of externals: (re-)learning to recognise the same stimulus sets that others do.

    Same with pain, except the stimulus sets are types of bodily trauma and hence partly or wholly internal. But pains are (analogously) traumas as classified through public pain-talk.

  • The meaning of the existential quantifier
    I'm trying to think how Goodman and Elgin might solve your dogs vs. coyotes problem...

    Btw though:
    A place where we see a more trivial side of ontological relativity is in the case of a finite universe of named objects. Here there is no occasion for quantification, except as an inessential abbreviation; for we can expand quantifications into finite conjunctions and alternations. Variables thus disappear, and with them the question of a universe of values of variables. And the very distinction between names and other signs lapses in turn, since the mark of a name is its admissibility in positions of variables. Ontology thus is emphatically meaningless for a finite theory of named objects, considered in and of itself. Yet we are now talking meaningfully of such finite ontologies. We are able to do so precisely because we are talking, however vaguely and implicitly, within a broader containing theory. What the objects of the finite theory are, makes sense only as a statement of the background theory in its own referential idiom. The answer to the question depends on the background theory, the finite foreground theory, and, of course, the particular manner in which we choose to translate or imbed the one in the other. — Quine: Ontological Relativity

    Is the aforementioned problem (and other ordinary talk) posable as a finite one, and would it help?

    Also:

    The only tenable attitude toward quantifiers and other notations of modern logic is to construe them always, in all contexts, as timeless. — Quine: Mr Strawson

  • The meaning of the existential quantifier
    As you like, it's just that math never uses quantifiers that range over even all mathematical objects,Srap Tasmaner

    So thanks, because what I needed was to think of searching "range of quantification", and it turns out that @SophistiCat's drift, which I recognised as a (kind of a) thing, was into what's called "bounded quantification". Thing is, though, it is a mere abbreviation:

    The existential proposition can be expressed with bounded quantification as

    ∃x∈D P(x)

    or equivalently

    ∃x (x∈D & P(x))
    Wikipedia

    It's an abbreviation that supports your point of view, that the range of quantification is restricted, but it doesn't resist undoing (as shown here), so that ∈ is a binary predicate and ∃ ranges over the whole domain of discourse - which in a mathematical discourse is presumably all mathematical objects, no?



    Also supporting your point of view:

    A [..] natural way to restrict the domain of discourse uses guarded quantification. For example, the guarded quantification

    For some natural number n, n is even and n is prime

    means

    For some even number n, n is prime.
    Wikipedia

    So yes, you can (informally at least) use "existence" to highlight more and more predicates (sub-domains?) applying to the specific entities you are about to assign a predicate.



    And then I think I might get your whole agenda here: you want to separate the process of identifying and setting up a target (which is to be the subject for a forthcoming predication) from the actual predication, the 'firing' of the predicate at that target. Anything like that?
