Aldous Huxley - As Portas da Percepção

On a bright May morning in 1953, Aldous Huxley took four-tenths of a gram of mescaline for the first time, dissolved in half a glass of water, and sat down to await its effects.

Shortly thereafter, everything around him transformed. This was the genesis of "The Doors of Perception" (1954), one of the most inspiring texts of the American counterculture of the 1960s. A meticulous record of sensory alterations and a philosophical essay exploring the liberating effects of this hallucinogenic substance, it is a visionary work on the workings of the mind and the human desire for transcendence. This edition also includes "Heaven and Hell" (1956), which explores the history and nature of transcendental experiences.
