Upon recommendation by Ginsberg, Olson participated in two psychedelic drug sessions with the Leary crew at Harvard’s Center for Research in Personality in December 1960 and February 1961. Despite Olson biographer Ralph Maud’s insistence that “These are strictly peyote sessions,” Olson himself refers to them as mushroom trips, and the Leary crew’s experiments during this time revolved around jars of synthetic psilocybin pills that they’d derived from Sandoz Laboratories in Switzerland. My sense, then, is that we can assume that synthetic psilocybin is what Olson received during his sessions. Each of these sessions was, in the poet’s own words, “a true love feast and a truth pill” (Muthologos, p. 24). “The startling & unbelievable first impression of going under the mushroom,” he stated, “is that everyone & everything is nothing but itself so that all — everything — is therefore well, and there’s no push, there’s no fuss, there’s nothing at all to worry about, or press at, no sweat of any sort called for, it’s all too real and way beyond any attitude or seeking some greater or bigger answer” (Olson, as quoted in Conners 106). A few years later, as Maud notes, “Olson gave to the Psychedelic Review for its third issue (1964) his long “MAXIMUS, FROM DOGTOWN—IV” (160). Psychedelic Review was a journal published by members of the Leary crew from 1963 to 1971. Olson saved in his library the first four issues of the magazine. In what follows, I’ll attempt to show how, when read in light of where it was published, Olson’s poem reveals itself to be a commentary on psychedelic experience.
