This course offers training in the logical and psycho-epistemological techniques of forming, organizing, and applying valid concepts-the areas where Ayn Rand's revolutionary discoveries.can most dramatically improve one's thinking. Topics covered include: the nature and axioms of logic, the practical meaning of "differentiation and integration," concept-formation, units and unit economy, conceptual hierarchy, how to avoid "floating abstractions," and how to determine essentials. The course is a combination of exposition and practical training, with class time approximately evenly divided between lecture and discussion of homework exercises, all of which are new.
