Whenever Ayn Rand met someone new—an acolyte who’d traveled cross-country to study at her feet, an editor hoping to publish her next novel—she would open the conversation with a line that seems destined to go down as one of history’s all-time classic icebreakers: “Tell me your premises.” Once you’d managed to mumble something halfhearted about loving your family, say, or the Golden Rule, Rand would set about systematically exposing all of your logical contradictions, then steer you toward her own inviolable set of premises: that man is a heroic being, achievement is the aim of life, existence exists, A is A, and so forth—the whole Objectivist catechism. And once you conceded any part of that basic platform, the game was pretty much over. She’d start piecing together her rationalist Tinkertoys until the mighty Randian edifice towered over you: a rigidly logical Art Deco skyscraper, 30 or 40 feet tall, with little plastic industrialists peeking out the windows—a shining monument to the glories of individualism, the virtues of selfishness, and the deep morality of laissez-faire capitalism. Grant Ayn Rand a premise and you’d leave with a lifestyle.
Stated premises, however, rarely get us all the way down to the bottom of a philosophy. Even when we think we’ve reached bedrock, there’s almost always a secret subbasement blasted out somewhere underneath. William James once argued that every philosophic system sets out to conceal, first of all, the philosopher’s own temperament: that pre-rational bundle of preferences that urges him to hop on whatever logic-train seems to be already heading in his general direction. This creates, as James put it, “a certain insincerity in our philosophic discussions: the potentest of all our premises is never mentioned?…?What the system pretends to be is a picture of the great universe of God. What it is—and oh so flagrantly!—is the revelation of how intensely odd the personal flavor of some fellow creature is.”
