Thomas Sowell's classic analysis of the opposing visions behind today's ethical and ideological disputes Controversies in politics arise from many sources, but the conflicts that endure for generations or centuries show a remarkably consistent pattern. This revised edition of a classic analyzes the centuries-long debates about the nature of reason, justice, equality, and power. It distinguishes between those with the "constrained" vision, which sees human nature as enduring and self-centered, and the "unconstrained" vision, in which human nature is malleable and perfectible. A Conflict of Visions offers a compelling case that these opposing visions are behind the ethical and ideological disputes of yesterday and today.,Provided by publisher.
