Beginning with the broadest philosophical issues--theories of existence, knowledge, and ethics--Landsburg then turns to a dazzling variety of specific applications. He gives us a mathematical analysis for arguments for the existence of God; explains the real meanings of the Heisenberg uncertainty principle and Gödel's incompleteness theorem; and carefully dissects the meaning of social responsibility on the playground, in the marketplace, and in the voting booth.

Stimulating, illuminating, and always surprising, The Big Questions reveals the relationship between the loftiest philosophical quests and our everyday lives.
