The Doors of Perception┬áis a philosophical essay, released as a book, by Aldous Huxley. First published in 1954, it details his experiences when taking mescaline. The book takes the form of Huxley’s recollection of a mescaline trip that took place over the course of an afternoon in May 1953. The book takes its title from a phrase in William Blake’s 1793 poem The Marriage of Heaven and Hell.

The lines appear at the end of the poem (full poem below this):

As Zoomologists, we are on a “trip” to open the Doors of Perspective.
