Leonard Peikoff discusses the “problem of seeming circularity”: if philosophy is a single, integrated whole, in which every point depends on every other point, where does the study of philosophy begin? How do you get started? Peikoff explains what gives rise to logical structure, thereby showing how Objectivism can have a definite hierarchical structure while nevertheless being an integrated system of ideas. Grasping this structure deepens one’s understanding and ability to prove philosophical points. Peikoff outlines the logical structure of Objectivism as presented in his book Objectivism: The Philosophy of Ayn Rand, contrasting it with the structure of his 1976 course, The Philosophy of Objectivism.
