Murray Rothbard's The Ethics of Liberty is a sweeping treatise which creates nothing short of a normative political philosophy of liberty. Contra Hume, Rothbard attempts to derive an "ought" from an "is," using natural law precepts and rigorous logic. Professor Walter Block joins the show to discuss the first section of the book, and gives us his unstinting (and always deontological!) take on Rothbard's vitally important treatment of natural law philosophy as the foundation for a free society. There are also lots of great Blockean anecdotes you'll want to hear!
