The Ontological Argument

Part of Philosophy>Philosophy of Religion

Overview

edit

The ontological argument proposes that God's existence can be proved a priori, that is, by intuition and reason alone. It was first put forward by Anselm of Canterbury in the Proslogium.

The argument works by examining the concept of God, and arguing that it implies the actual existence of God; that is, if we can conceive of God, then God exists — it is thus self-contradictory to state that God does not exist. This is obviously a controversial position, and the ontological argument has a long history of detractors and defenders.

The argument's different versions arise mainly from using different concepts of God as the starting point. For example, Anselm starts with the notion of God as a being than which no greater can be conceived, while Descartes starts with the notion of God as being maximally perfect (as having all perfections).
