Does God Exist?

The classical theistic proofs come in three flavors: ontological (from the very concept of God — Anselm, Descartes), cosmological (from the existence of anything contingent — Aquinas, Leibniz), and teleological (from the apparent design of the world — Aquinas, Paley). Hume's Dialogues Concerning Natural Religion devastated the design argument; Kant showed the ontological argument illegitimately treats existence as a predicate; Russell publicly debated the cosmological argument with Father Copleston in 1948. The arguments still have defenders. They still have critics. Nobody has knocked the other side out.
