Ayn Rand embraced Aristotelian logic but took it much further. This course, through lectures and homework exercises, reviews the three most important ideas of Aristotelian logic and then focuses on the new principles of proper thinking developed by Ayn Rand. Topics will include: concept-formation, axioms, the syllogism, the need for and rules of proper definition, hierarchy, context-holding, thinking in principles, thinking in examples, and logical fallacies from equivocation to the stolen concept.
