Anselm of Canterbury (11th century) was the first to present the ontological argument, purporting to demonstrate God’s existence through a mere analysis of the definition of God. Aquinas rejected the argument, but Descartes revived it. Kant was thought by many to deliver it a death blow, but it continues to be resuscitated. This lecture is an exercise in philosophical detection: Dr. Mayhew will present the argument and then explain Objectivism’s unique reasons for rejecting it as not merely false, but as an absurd rationalization.
