At every point when it is alive.

That's not true, does a single neuron has an opinion ? two ? a thousand ?

We may not call them opinions

Don't switch subject.

    because
    we use that word to refer to an entire human being's experience, but
    the point is that being a living cell makes it capable of having
different capacities than it does as a dead cell.

Yes and so what ? a dead cell *does not* behave like a living cell, that's enough.

    When it is dead,
    there is no biological sense going on, only chemical detection-
    reaction, which is time reversible. Biological sense isn't time
    reversible.

No, because there is no such thing as absolute simulation,

There is no need for an "absolute" simulation... what do you mean by "absolute" ?

    there is
    only imitation. Simulation is an imitation


no, simulation is not imitation.

    designed to invite us to
    mistake it for genuine - which is adequate for things we don't care
    about much, but awareness cannot be a mistake. It is the absolute
    primary orientation, so it cannot ever be substituted. If you make
    synthetic neurons which are very close to natural neurons on every
    level, then you have a better chance of coming close enough that the
    resulting organism is very similar to the original. A simulation
    which
    is not made of something that forms a cell by itself (an actual
    cell,
    not a virtual sculpture of a cell) probably has no possibility of
    graduating from time reversible detection-reaction to other
    categories
    of sense, feeling, awareness, perception, and consciousness,
    just as a
    CGI picture


A CGI picture *is a picture* not a simulation.

    of a neuron has no chance of producing milliliters of
    actual serotonin, acetylcholine, glutamate,etc.


Is it needed for consciousness ? why ?

Hi,

How would your reasoning work for a virus? Is it "alive"? I think that the notion of "being alive" is not a property of the parts but of the whole.

Which is the very basic idea sustaining comp. But Craig seems to defend the opposite idea. He believes that life, sense, and consciousness must be present in the part to sum up in the whole. A mechanist will insist that it is the property of the whole which is responsible for the higher order aptitude, like being able to play chess, or having a private experience.

Hi Bruno,

No. Craig can be considered to be exploring the implications of Chalmer's claim that consciousness is a fundamental property of the physical, like mass, spin and charge, i.e. it is not emergent from matter. His concept of "sense" is not much different from your 1p or the content of a "simulation".


Yet, the case of "living" and "conscious" are not entirely equivalent, and should be treated differently. The definition of life seems to me conventional, but being conscious is everything but conventional.

We agree on that! "Living" does seem to be 3p definable while "conscious" is only 1p definable.

Onward!

Stephen
