Books like The Act of Creation

Startlingly lucid account of our most wondrous and irrational faculty: creativity. In the space of a few chapters, Koestler throws light on the question of humor: what makes a joke funny? And why do we, unlike every other animal, laugh? But this conception, while the most illuminating view of humor I've read, is only the start of a much grander theory of our most profoundly human activities. He finds the unifying thread of the three great creative acts of mankind: Humor, Art, and Scientific Inventiveness. One of those books that changes your understanding of consciousness forever.
