- Author’s conclusion:-
- Similarly1 with all mental phenomena, including both access and phenomenal consciousness. Even though there is nothing spooky about it (bye-bye to any form of dualism), specific numbers and arrangements of neurons seem not to be sufficient to generate those phenomena. The involved neurons also need to be made of (and produce) the right stuff: it is not just how they are arranged in the brain that does the trick, it also takes certain specific physical and chemical properties that carbon-based cells have, silicon-based alternatives might or might not have (it’s an open empirical question2), and cardboard, say, definitely doesn’t have.
- It follows that an explanation of phenomenal consciousness will come (if it will come – there is no assurance that, just because we want to know something, we will eventually figure out a way of actually knowing it) from neuroscience and evolutionary biology, once our understanding of the human brain will be comparable with our understanding of the inner workings of our own computers. We will then see clearly the connection between the underlying mechanisms and the user-friendly, causally efficacious representations (not illusions!) that allow us to efficiently work with computers and to survive and reproduce in our world as biological organisms.
- The analogy is with the emergence of wetness from appropriate aggregates of water molecules in appropriate conditions.
- While I’m sympathetic to this claim, just what empirical data would validate the claim?
