But for ''II)" I have some things to say. Logic is enough to accept that consciousness is either a. 100% reducible, b. not 100% reducible, or c. fundamental. — Eugen
According to him, consciousness is emergent (he says that "radical emergence" happens all the time, which I think is true), as is liquid from molecules who appear to lack this property in isolation.
You would perhaps reply by saying that this means consciousness must be reducible to particles, because if it is emergent, the reduction follows. Not quite. Consciousness arises in brains, which are a very specific arrangement of matter, as far as we can see 99.999999% of the universe doesn't have creatures with brains.
But saying consciousness is reducible to brains doesn't make any sense, how is that a reduction? I don't see how a brain is a "lower level" phenomena of mind, it seems to me to be a higher one, in terms of, we discover brains through consciousness, otherwise, we couldn't even postulate them.
So Chomsky would
invert the now classical slogan "the mental is the neurophysiological at a higher level." I believe he discusses this in
New Horizons in the Study of Language and Mind. Or if not, in the first essay of
Power and Prospects. Don't remember which one.
Q1. So by saying consciousness isn't reducible to matter, does Chomsky leave the room open for options b and c, or he is saying that there are other options that our mind cannot comprehend?
Q2. If the latter, why would he believe that? — Eugen
It's in the provided essay. We don't know what matter is, almost nothing about it. Physicists don't even agree on what a particle is - that's a problem. What we do know about matter quite intimately, are its (conscious) mental aspects, what we see, feel, talk with others, read, etc. That's as clear as anything could be for a human being.
Newton proved we don't understand motion: we provide descriptions for in our theories, but we don't have the capacity to understand it, which he made clear in his famous "It is inconceivable..." quote.
Understanding the world vs. understanding theories of the world, are very different things. The latter is a massive lowering of standards of understanding.
And what happened with the problem of motion? We simply got used to it, in fact, we take it for granted, forgetting we don't understand it, outside our theories.
If we can't understand motion, it is unlikely we will comprehend how matter can think. We know we are thinking matter, but we don't understand how it is possible. He quotes Locke and Priestley here, and several others, worth looking at the article.
