Plain Theism is the view that ‘God exists’ is a logically contingent proposition. ‘God exists’ is neither necessarily true nor necessarily false. In contrast, necessitarian theism holds that the proposition, ‘God exists’ is necessarily true. In other words ‘it is false that God exists’ is a contradiction.

What does it mean to say that God does not have necessary existence or that ‘necessarily, God exists’ is necessarily false? Most theists contend that if ‘God exists’ is true, it is true necessarily. The answer, I think, lies in some of Dr. Yandell’s theistic argumentation.

In this argument, he teases out an assumption that works for the argument but entails plain theism. Due to the length of the argument, let me present a ‘supplemental’ argument for the conc...
