In 1952 Aldous Huxley became involved in the now legendary experiment to clinically detail the physiological and psycho-logical effects of the little known drug used by Mexican and Native American elders in religious practices. The drug was Peyote-now commonly know as mescalin. By the standards of the time, Huxley was a hard working, respected, and reserved intellectual from a highly intelligent, well-know, and eccentric British family. By any standards, the results of the experiment were remarkable. The Doors of Perception and Heaven and Hell detail the practic-alities of the experiment and give Huxley's vivid account of his im-mediate experience and the more prolonged effect upon his sub-sequent thinking and awareness. At first, the reader is drawn in by the sheer naivety and tom-foolery of the proposal but is soon caught in a finely woven net by the juxtaposition of Huxley's formidable intellect, his remarkable ability to convey the experience in such acute and truthful detail, and his incredible modesty.
