Abstract
This essay armies that Kant's philosophy provides a justification for free markets. The myths about Kant are that he was a recluse, knew nothing about business, and that his epistemology divorced reason from reality, while his primary interest was metaphysics. Yet Kant's categorical imperative demands obedience even in the face of uncertainty about the external world. Adam Smith described this principle as the inward testimony of an impartial observer. Smith and Kant put individual decisions at the center of morality, but agreed that people have a tendency to make morally inferior choices. Those who propose to regulate the economy are as troubled by this tendency as those they regulate. The self-sacrifice prescription is economically, psychologically, and morally unstable. In recommending market competition. Smith was unconsciously applying a Kantian formula. Market decisions are individual decisions. Individuals prefer to do business with those they trust: this is an incentive to honesty. A morality that depends upon incentives is imperfect but superior to a morality imposed by force.
