Creativity involves the depth of a mind, and many, many depths of unconsciousness.
Creativity...involves the power to originate, to break away from the existing ways of looking at things, to move freely in the realm of the imagination, to create and recreate worlds fully in one's mind-while supervising all this with a critical inner eye.
I think there are dozens or hundreds of different forms of creativity. Pondering science and math problems for years is different from improvising jazz. Something which seems to me remarkable is how unconscious the creative process is. You encounter a problem, but can't solve it.
