It’s fine to say, “There’s a brain, and it’s obviously conscious. If I hit you with a sledge-hammer, you will no longer be conscious. Therefore, the brain, an evolved organ, is immediately responsible for your consciousness; and the process of evolution in general, being responsible for the brain, includes the evolution of consciousness.”
But that’s a bit of a dodge. The question is why ANY material system, including the Universe as a whole, would allow for the existence of consciousness, rather than a total lack of it. And when I say consciousness, I don’t mean the ability of a physical system to take in data, process it, and output a behavior. I’m talking about qualia, the capacity to experience subjectively what things are like.
So far as I know, there’s nothing about a material world view in general, or about a scientific world view specifically, which even BEGINS to explain why such a thing as consciousness exists in the Universe.
So far, we have:
- The Big Bang
- ???
- Consciousness!
Keep in mind that I declare as agnostic, not as Christian or Catholic. But given that the existence of physical states implies previous physical states, I think it’s not unreasonable to suppose that the existence of mental states implies previous mental states.
If you had a mental singularity which unfolded into all the conscious entities in the Universe, I’d say you could reasonably call that God. The Bible says, “I am the alpha and the omega,” which means the beginning and the end are one, which I think reasonably represents a conscious singularity.
