This is a stand-alone Q&A session given by Leonard Peikoff as part of the course Moral Virtue. In addition to questions on general philosophy, Peikoff extensively discusses his article “Fact and Value,” which deals with the cognitive basis of evaluation.

This lesson consists of a recorded lecture that Peikoff gave in 1989, based on thinking he did for his book Objectivism: The Philosophy of Ayn Rand, published in 1991.
