Catalog description

This course will survey a number of famous paradoxes about the nature of time, identity, logic, science, belief, decision, and value. Some of these paradoxes have widely accepted answers, but many do not. Paradoxes include (but are not limited to) Zeno's paradoxes, the sorites paradox, the liar paradox, paradoxes of probability, the doomsday and simulation arguments, Newcomb's puzzle, and the trolley problem. These paradoxes will be used as a stepping stone to deeper philosophical questions. Some of the questions we'll tackle include: Is time real? What is a person? Is infinity coherent? How is science possible? What is knowledge? What is it to be rational? What should we do? Does God exist? And finally, why is death bad?
