Could drugs offer a new way of seeing the world? In 1953, in the presence of an investigator, Aldous Huxley took four-tenths of a gramme of mescalin, sat down and waited to see what would happen. When he opened his eyes everything, from the flowers in a vase to the creases in his trousers, was transformed. His account of his experience, and his vision for all that psychedelics could offer to mankind, has influenced writers, artists and thinkers around the world.
