Wertham and Bleuler, Inconstancy of the Formal Structure of the Personality. The general thesis of these experimenters was that personality types might be studied as they were exteriorized in mescaline intoxication via the Rorschach test. One of the observers described two personalities in a normal subject in two periods of intoxication, not knowing that it was the same person. They conclude, interestingly: “It is suggested that these observations indicate that the form of a personality is not a constant, but that it may be influenced by outer circumstances, and that the usual psychologic ‘type’ of a person does not necessarily exhaust the description of the formal structure of his personality.”
