This topic (and Science) are very much a continuation of Philosophy. It’s extending those basic ideas into the very relevant topic of the mind.
To start we need a foundational definition of consciousness because it’s the longest standing question of the mind (going back before science was given a name). Hofstadter is where you’ll find it.
Next I would go to Copies because it’s an intriguing, hopeful and yet possibly terrifying extension of that definition.
