The phenomenal effects of LSD in medically supervised psychotherapy were apparent soon after its discovery in 1948. Since then, other new, equally effective psychedelics have been developed, and in sound therapeutic situations, their usefulness is now almost beyond dispute. The psychedelics free the mind to fantasize, and the vivid reliving of strong emotion, rather than the mere recall of it, is the hallmark of this "furious therapy."

The first part of Mr. Caldwell's book, based on the author's interviews and research, is a survey of modern drug treatment both in this country and abroad. The second part is devoted to the description and classification of basic, universal images and fantasies as they manifest themselves under the hallucinogens.

Mr. Caldwell points out that the psychedelic drugs are too strong to be safe for do-it-yourself experiments. But their ability to reach quickly to the deepest strata of the unconscious has become a challenge to all those interested in new ways of exploring and healing the human mind.
