The Doors of Perception by Aldous Huxley is a key work in the never psychedelic non-fiction genre. It has inspired millions of readers and the book gave the name to the band The Doors. Huxley also wrote Brave New World, The Perennial Philosophy, The Devils of Loudon and more. From the book:
“I took my pill at eleven. An hour and a half later, I was sitting in my study, looking intently at a small glass vase. The vase contained only three flowers-a full-blown Belie of Portugal rose, shell pink with a hint at every petal’s base of a hotter, flamier hue; a large magenta and cream-colored carnation; and, pale purple at the end of its broken stalk, the bold heraldic blossom of an iris. Fortuitous and provisional, the little nosegay broke all the rules of traditional good taste. At breakfast that morning I had been struck by the lively dissonance of its colors. But that was no longer the point. I was not looking now at an unusual flower arrangement. I was seeing what Adam had seen on the morning of his creation-the miracle, moment by moment, of naked existence.”
