        Languages are tools. There is no truth "out there".

        My view is that "true" means different things in different
        contexts.

        And in different modes (of self-reference). The platonists
        dis understand that the absolute truth requires faith in
        something beyond “my consciousness” or “consciousness” (to
        take into account Terren Suydam’ remark).


    Wittgestein up to now still has the upper hand with those old
    arguments over anybody proposing science based ontological
    packages metaphysically: language will seduce people to
    overgeneralize, to confuse personal mysticism with reality, to
    engage in false equivalencies between terms used in formal
    contexts and everyday use of language, scientism etc. Slowly,
    yours truly is coming around to the idea that folks agreeing on
    ontology/reality/religion, which would guide research in some
    allegedly correct direction; spilling over positive effects into
    the world... that Wittgenstein may prove correct in that this is
    a confused product of muddled armchair thinking, not because of
    his generally negative stance, but because there seem to be
    positive developments out there that he couldn't have informed
    those arguments with.

    I see/predict metaphysics shifting from the naive armchair forms
    of identity, reality, matter etc. practiced here on this list
    with profound erudition, walking in circles for 20 years now
    (Wittgenstein says thousands of years) to optimization and more
    efficient pursuit of value and benefit questions instead,
    through say orchestration of highly sophisticated forms of
    organization applied to education, governing, finance,
    technology, problem solving, applied or theoretical etc. that
    are permissionless, universally accessible, require no hierarchy
    of politics, charlatan experts, control freaks, their
    sycophants, and bibles of some Messiah achieving miracles such
    as eternal life, self-duplication etc.

    Metaphysical setups that place less emphasis on truth, trust,
    power, control, or proof and more emphasis on "can entities such
    as ourselves be highly organized, solve specific survival
    problems over short and long terms, without trusting each other
    + instead assuming that folks will be opportunistic and
    idealistic?" Example: we don't agree on what reality may be, but
    we do agree on the need for habitable living space in the long
    term, nutrition, water, health, limiting self-destruction,
    expensive wars, standards of living etc. quite clearly. There
    ARE more appropriate politics and economics on the horizon.
    Metaphysics here, shifting our old-school conceptions of what
    first principles are, and you'd refute Wittgenstein instead of
    running from him. Engineering incentive and not what the game is
    but /how/ the game of life on this planet could be.


        About this, it is clear to me that in “I think thus I am”,
        Descartes use the “first person” I. Indeed he start from the
        doubt. Dubito ergo cogito, cogito ergo sum. Descartes did
        not prove the existence of Descartes, bit of his own
        consciousness, hoping others can do the same reasoning for
        themselves. Consciousness always refer to a first person
        experience implicitly: like God (truth) it is not a thing.


    You concede to Terren that "true means different things in
    different contexts" but everyday like clockwork you still
    barrage the list with your use of "large truth, 3p, reality that
    cannot be named, mechanism is incompatible with physicalism" and
    all the rest of it. I used to wonder why you don't pursue
    contact with linguists, physicists, a wider audience, and
    philosophers but this has ceased to surprise me. PNGC


I think I finally got it -- what mechanism means for Bruno -- namely, that a human being can be perfectly simulated by a computer. But if that's what he means, how does it follow that mechanism is incompatible with physicalism?

Because all possible computations (in the Turing sense) are implicit in arithmetic.  And Bruno thinks arithmetic exists, and hence all threads of human (and non-human) consciousness exist in arithmetic.

What exactly does Bruno mean by physicalism?

That physics is the basic science; i.e. the ontology of physics, whatever it is, must give rise to everything else, including conscious thought.

Why the incompatibility? Bruno? TIA, AG

Bruno's a fundamentalist.  You can only have one, really real, true fundamental ontology.

Given the sense of “fundamentalism” in the religious (pseudo-religious) domain, it might be useful to make precise that I do not defend any theory or religion. I just say that IF we can survive with an artificial brain, then physics becomes the science of available predictions by universal machine implemented in arithmetic.

If arithmetic exists independent of physics.

Brent

And that this makes Mechanism Versus Materialism testable, and indeed confirmed by the observation, notably by QM without collapse. There is a "many-world" interpretation of arithmetic (in the head of all universal numbers), and we can test it. We can use any Turing universal formalism instead of arithmetic. They all lead to the same theology, and the same physics.
