In the previous lecture Professor Swinburne discussed arguments for the existence of God. I do not propose to put forward arguments for the non-existence of God, precisely. Rather I want to discuss the view that the whole enterprise of putting forward arguments for the existence of God is misguided. Moreover, I hold that it distorts the nature of religious belief. This in turn raises the question of the rationality of religious belief. A belief that cannot be based on argument, however broadly understood, does not seem to be a rational belief. Is religious belief, therefore, irrational, contrary to reason? We shall see. This, at least, is my programme.
