ABSTRACT
All the arguments which we have looked at so far have been directly supporting theism, and one direct consequence has been that if they are sound, then atheism is false. The argument which we consider in this chapter has a different form: it is an argument for the conclusion that atheism and agnosticism are untenable, which (if the argument is sound) has as a consequence the conclusion that only theism is tenable. Although versions of the argument can be found in several writers, the most detailed presentation of it is by Plantinga, and we can therefore usefully take his version as canonical.1
