Why Should One Act on Principle

Total Time: 1 hour, 31 minutes

In this path-breaking lecture, Dr. Leonard Peikoff contrasts the modern complexity worship with a life lived according to principles. He identifies what a principle is and how principles are essential for thinking and acting through all branches of philosophy. Rejecting the pragmatic approach of the moderns, Peikoff illuminates the uniquely human perspective that is gained by principles.
