Imagine a society that subjects people to conditions that make them terribly unhappy, then gives them the drugs to take away their unhappiness. Science fiction? It is already happening to some extent in our own society... Instead of removing the conditions that make people depressed, modern society gives them antidepressant drugs. In effect, antidepressants are a means of modifying an individual's internal state in such a way as to enable him to tolerate social conditions that he would otherwise find intolerable.
Each sporadic burst of work, each minor success and disappointment, each moment of calm and relaxation, seemed merely a temporary halt on my steady descent through layer after layer of depression, like an elevator stopping for a moment on the way down to the basement.
