Anselm's Neglected Argument


Brian Leftow 

Abstract

Anselm is commonly credited with two a priori arguments for God's existence, the non-modal argument of Proslogion 2 and a modal argument some find in Proslogion 3. But his Reply to Gaunilo contains a third. The argument as Anselm gives it has flaws, but they are not fatal, and its main premise can serve as the basis of a simpler, stronger argument.
