I believe most things about us cannot be explained in chemical or physical terms, and this is where I disagree with most of my colleagues who study the human brain. They believe that at some point in the future, we will have studied every single neuron in the brain, and then we’ll be able to explain everything. My take on it is - no, we won’t. … Because there are things that cannot be explained through physiology or neural networks. To name a few, it’s anything that has to do with feelings, anything related to art, and other subtle matters.
