Query: Masterpiece of Pop-Philosophy

Nozick's A, S, and U is a great work of philosophy; not merely for its clear and forceful arguments, but because of its ability to act like a textbook. With ASU, you get a broad coverage of political theories, ethical theories, theories about argument, economics, government and more. Highly recommended for anyone who is doing philosophy at an undergraduate level.
