One of the most notable economists and social philosophers of the twentieth century, Ludwig von Mises, in the course of a long and highly productive life, developed an integrated, deduct­ive science of economics based on the fundamental axiom that in­dividual human beings act purposively to achieve desired goals. Even though his economic analysis itself was “value-free” — in the sense of being irrelevant to values held by economists — Mises concluded that the only viable economic policy for the human race was a policy of unrestricted laissez-faire, of free markets and the unhampered exercise of the right of private property, with government strictly limited to the defense of person and property within its territorial area.
