"From these reflections there arise intuitive insights of astonishing clarity, and because there is little difficulty in remembering them after the effects of the psychedelic have ceased (especially if they are recorded or written down at the time), the days or weeks following may be used for testing them by the normal standards of logical, aesthetic, philosophical, or scientific criticism. As might be expected, some prove to be valid and others not. It is the same with the sudden hunches that come to the artist or inventor in the ordinary way; they are not always as true or as applicable as they seem to be in the moment of illumination. The drugs appear to give an enormous impetus to the creative intuition, and thus to be of more value for constructive invention and research than for psychotherapy in the ordinary sense of “adjusting” the disturbed personality. Their best sphere of use is not the mental hospital but the studio and the laboratory, or the institute of advanced studies." quote by Alan Watts
