Moksha is an impressive compendium of Aldous Huxley's texts about hallucinogenic drugs, their effects, their possibilities, their risks, etc. In this complete anthology, letters with scientists and researchers alternate, popular articles and short excerpts of essays and scenes from some of his novels in which drugs play an important role (The Island, A Happy World). In this field, Huxley became in his time (and continues to be) one of the most authoritative, acute, unprejudiced and lucid voices, which earned him the respect of both the scientific community and those who in the late 1950s began to experiment with LSD.
