September 12, 2001 The Problem of Evil Last time we considered the ontological argument for the existence of God. If the argument is cogent, then we have reason to be rational theists, i.e., to maintain that there are justifying reasons for belief in God's existence. Today we're going to consider an argument for atheism which purports to show that theism is incoherent, i.e., that theism entails a contradiction. If the argument works, then the only option available to the theist would be irrational theism: belief in God's existence in spite of justifying reasons supporting
