I am an unhappy man. I am haunted by my inability to express the inexpressible, to come to terms with the unknown. The pursuit of beauty is, of course, a major psychological drive. In its various guises -- which is to say, the urge to perfection, the yearning to merge with the eternal, the explorer's restlessness, the realization of an Absolute created by ourselves, yet larger than our totality -- it is perhaps the most single important human thrust.
