In a recently published volume on classical apologetics, three defenders of classical Christian theism offer what they believe is a new and valid form of the ontological argument. I The argument proceeds by a number of steps. It is not impossible that a necessary being exists. This may be formulated as "A necessary being may exist." However, such an expression is absurd, for a necessary being by
... [Show full abstract] definition must exist." In discovering the possibility of God, we have discovered the certainty of God, unless it can be shown that the argument is done by mirrors, by linguistic legerdemain. ''s At this stage however nothing has been established. It is self evident that a necessary being cannot possibly exist, if it exists necessarily. But, the question remains, does it exist? Sproul, Gerstner and Lindsley now go on to develop what is the most interesting part of what they claim is a demonstrative proof for the existence of God. In reviewing Anselm's form of the ontological argument, as is contained in the Proslogion 1-4, the authors accept the criticism that this particluar expression does not move out of the realm of idea. However, this is only because Anselrn did not state the argument fully. "The full argument would include the implicit observation that we cannot think of the nonexistence of God. That proves God's existence, inasmuch as the inability to think of or conceive of an entity's nonexistence is the most compelling type of proof. We know we now exist because, while we are existing, we cannot think of our not now existing. The same is true of the chair on which we are now sitting. This is implicit in Anselm's argument. ''3 This addition to the ontological argument in its oldest form is meant to get around the objection of Kant that this type of argument can never get beyond concepts. 4 The idea of a perfect triangle implies the idea of the existence of a perfect triangle and nothing more. Likewise the idea of a perfect being implies merely the idea of an existing perfect being. There is, it is claimed, a crucial difference between these two ideas. "We can think of the nonexistence of a perfect triangle, but we cannot think of the nonexistence of a perfect being. We cannot think
