There is much beauty in the superficial complexity of nature. But there is a deeper beauty in the simplicity of underlying processes that account for the external complexity. There is beauty in the intricacy of human thinking when an intelligent person is confronted with a difficult problem. But there is a deeper beauty in the basic information processes and their organization into simple schemes of heuristic search that make that intricate human thinking possible. It is a sense of this latter beauty—the beauty of simplicity—that we have tried to convey to you.
