Pat was being a whiny, entitled bitch, so he made Ben explain the "philosophy" of famous novelist/cult leader Ayn Rand. Pat learns how she used her turgid, hackneyed, pedantic novels as a platform for her ideology, Objectivism. Objectivism is a half-baked philosophy for petulant toddlers emphasizing selfishness as a virtue and rapacious capitalism as the best economic system. Her followers are insufferable. Don't ever talk to them.
