Perhaps they've reached a 'model' that has it right on Alpha Centauri. No telling how long it takes conscious beings to understand consciousness fully enough to 'model' it. We do have, however, various 'models' of perception and we have discussed them and disagreed about their validity. Perception is the 'without which nothing' [the
sine qua non] on the basis of which protoconsciousness evolves toward consciousness in living beings. Perception is the opening -- the openness -- that links us to the natural world from which we and species preceding us in evolution have evolved situated perspectives on the world
as we exist within it -- out of the natural affordances by which we sense, feel, and increasingly know our physical and temporal presence within it.
That's a very mystical idea, and perhaps Steve (
@smcder ) can identify it in one or more articulated texts of Eastern philosophy. I don't dislike the idea as an effort to understand what-is holistically. I do think that it is more interesting to explore the ways and means by which this idea becomes thinkable in Eastern mysticism and Western phenomenology.
There is more to being than perceiving.
As I read him, Chalmers was protesting both radical dualism and reductive materialism. What I meant by Hoffman's "going off the rails" is that he goes entirely off the rails of our empirical experience in and of the tangible and thinkable world in which we exist, which in my view (as in James and the phenomenologists) is what we have to work with in understanding the nature of 'what-is' as we confront it.
