An extremely interesting topic from a one-sided viewpoint. Zaehner’s use of derogatory phrases such as “apostles of the psychedelic cult” and “propagandists of psychedelic religion” to describe anyone who is interested in the possibility that entheogens could produce a mystical state…is a good example of his position. His tone is sometimes quite mocking and he seems entrenched in traditional religious thought. A serious work that we couldn’t take seriously.
