It’s a major point of contention whether consciousness can be reduced to the laws of physics or biology. The philosopher David Chalmers has speculated that consciousness is a fundamental property of nature that’s not reducible to any laws of nature.
I accept that, except for the word “fundamental.” I argue that consciousness is a property of nature, but it’s not a fundamental property. It’s quite easy to argue that there was a big bang very long ago and long after that, there was an emergence of life. If Chalmers’ view is that consciousness is a fundamental property of the universe, it must have preceded even the emergence of life. I know there are people who believe that. But as a scientist, when you look at the weight of the evidence, it’s just so much less plausible that there was already some sort of elementary form of consciousness even at the moment of the Big Bang. That’s basically the same as the idea of God. It’s not really grappling with the problem.
