R.E.L. Masters and Jean Houston. 
 
Holt Rinehart Winston: 1966. First edition. Hardcover in a jacket. Octavo. Small tears and folds along the top of the jacket. A little soiling and fading to the jacket, easy to see because of the off-white. Very slight bumping to the crown and heel of the spine of the book. A small stain on the top edge of the text block. There's also a very small fold and tear at the bottom of the last few leaves. 326 pages. Very good. 
 
You know a lot about psychedelics. When, in the course of a trip, the levels of awareness increase until a personality change is catalyzed; how the rich inner life of a healthy person can be revealed; what a rigorous training for a psychedelic "guide" looks like. And academic power couple the Masters (sexual behavior psychiatrist and professor of philosophy, respectively) reflect on all of this, and more, after fifteen years of documented research on non-addictive psychedelic substances. So they'll have something unexpected and rich for even you, and in a great looking first edition. Includes as ephemera a pamphlet from the FDA on Drugs of Abuse: Stimulants, Depressants, and Hallucinogens. 
 
"We, the authors of this book,  do not agree that psychedelic drug research should be confined to medical and psychotherapeutic areas of use. And it is toward a much wider horizon of productive exploration and application that we intend our book to point."
