We live in a universe of apparent dualities: light and darkness, reason and romance, order and chaos. Exploring the interplay of form and energy, David Wade takes the reader on a journey through the world of successive ages--from Plato's conception of the ideal form and the ancient Chinese philosophy of change to the modern scientific view of structure and indeterminacy as embodied in the laws of physics. The author shows us how perceptions about the nature of the universe are reflected in the art of of a given period. He details the form and fluidity of prehistoric art, the crystalline order of Islamic patterns, and the subtlety and vitality of Chinese landscapes and calligraphy.
