Here is an excerpt:
Galileo, as it were, stripped the physical world of its qualities; and after he’d done that, all that remained were the purely quantitative properties of matter—size, shape, location, motion—properties that can be captured in mathematical geometry. In Galileo’s worldview, there is a radical division between the following two things:
- The physical world with its purely quantitative properties, which is the domain of science,
- Consciousness, with its qualities, which is outside of the domain of science.
What do these 17th century discussions have to do with the contemporary science of consciousness? It is now broadly agreed that consciousness poses a very serious challenge for contemporary science. Despite rapid progress in our understanding of the brain, we still have no explanation of how complex electrochemical signaling could give rise to a subjective inner world of colors, sounds, smells and tastes.
Although this problem is taken very seriously, many assume that the way to deal with this challenge is simply to continue with our standard methods for investigating the brain. The great success of physical science in explaining more and more of our universe ought to give us confidence, it is thought, that physical science will one day crack the puzzle of consciousness.
