Abstract
In this paper it is argued that, while the case that Antony Flew makes against philosophically invalid arguments for the existence of God is generally sound, he fails to comprehend the power and cogency of the ontological argument. Thus, his conception of the grounds of morality, separate from the biblical tradition of theology, is by no means compelling. This paper aims to show that the rational concept of morality that Flew rightly claims to uphold is not only consistent with but also presupposes, paradoxically, the ontological argument for the existence of God. Central ideas of Kant and, above all, of Spinoza are called upon to show that the nexus between morality and theology, between philosophy and God, is that central to the ontological argument. The conclusion of the paper is that, just as philosophy without God is empty, so God without philosophy is blind.
