Here Nozick continues his search for the connections between philosophy and "ordinary" experience. In the lively and accessible style that his readers have come to expect, he offers a bold theory of rationality, the one characteristic deemed to fix humanity's "specialness." What are principles for? asks Nozick. We could act simply on whim, or maximize our self-interest and recommend that others do the same. As Nozick explores rationality of decision and rationality of belief, he shows how principles actually function in our day-to-day thinking and in our efforts to live peacefully and productively with one another.

Rationality of belief, according to Nozick, involves two aspects: support by reasons that make the belief credible, andgeneration by a process that reliably produces true beliefs. A new evolutionary account explains how some factual connections are instilled in us as seemingly self-evident, thus reversing the direction of Kant's "Copernican Revolution." Proposing a theory of rational belief that inc
