De Quincey’s wicked book
By Robert Morrison
In The Metaphysics of Morals (1797), Immanuel Kant gives the standard eighteenth-century line on opium. Its “dreamy euphoria,” he declares, makes one “taciturn, withdrawn, and uncommunicative,” and it is “therefore…permitted only as a medicine.” Eighty-five years later, in The Gay Science (1882), Friedrich Nietzsche too discusses drugs, but he has a very different story to tell.
