La Naturaleza De La Racionalidad

Repeatedly and successfully, the celebrated Harvard philosopher Robert Nozick has reached out to a broad audience beyond the confines of his discipline, addressing ethical and social problems that matter to every thoughtful person. 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. In Nozick's view, misconceptions of rationality have resulted in many intractable philosophical problems.

For example, the Kantian attempt to make principled behavior the sole ultimate standard of conduct extends rationality beyond its bounds. In this provocative volume, Nozick reformulates current decision theory to include the symbolic meaning of actions in areas from controlling impulses to fighting society's war against drugs. The author proposes a new rule of rational decision, "maximizing decision-value," which is a weighted sum of causal, evidential, and symbolic utility.
