LEARY, Timothy. Multilevel Measurement of Interpersonal Behavior. Berkeley: Psychological Consultation Service. 1956.

4to. Original blue printed wrappers; pp. [viii], 110, with several in-text diagrams and graphs; wrappers slightly discoloured in places, with a few marks and light wear to extremities.

First edition of the scarce debut publication by the future icon of psychedelic counterculture.

Multilevel Measurement of Interpersonal Behavior marks Timothy Leary’s first foray into print, produced while he was still working as an assistant professor at Berkeley. Just a few years later, as a Harvard lecturer, he would become a central – and controversial – figure in the psychedelic movement. Fired in 1963 for his drug experiments, Leary became the “high priest of LSD”, champion of the “Psychedelic Renaissance”, and author of the legendary slogan: Turn on, tune in, drop out.

This early study on interpersonal dynamics belongs to Leary’s pre-psychedelic phase, but already reflects his deep interest in the structures of personality and human behaviour. He would later develop these ideas more fully in Interpersonal Diagnosis of Personality (1957), before taking a radical turn toward consciousness expansion.
