An Enquiry Concerning the Principles of Morals (HPC Philosophical Classics Series)
A splendid edition. Schneewind's illuminating introduction succinctly situates the Enquiry in its historical context, clarifying its relationship to Calvinism, to Newtonian science, and to earlier moral philosophers, and providing a persuasive account of Hume's ethical naturalism. --Martha C. Nussbaum, Brown University
