This course will be an introduction to the most influential and mind-boggling philosophical paradoxes, from ancient times to the present. Included will be paradoxes of space and time (Zeno's paradoxes, the twin paradox in relativity); paradoxes of decision-making (Prisoner's Dilemma, Newcomb's problem, two-envelope paradox); paradoxes of belief and knowledge (Sleeping Beauty paradox, the Doomsday argument, the Surprise exam, the Lottery paradox); and paradoxes of logic and set theory (Russell's paradox, the Liar paradox, the Sorites paradox).
