Will, Thinking, Theology

While 'Free Will vs. Determinism' is typically categorized as a 'Metaphysical' debate in contemporary Philosophy, it is actually a vestige of a Theological problem.  For, what is originally, for Aristotle, a situational Psychological nuance--Voluntary vs. Involuntary--becomes exaggerated as the solution to the following Theological conundrum: 1. God is omnipotent; 2. God is good; 3. Evil exists.  That is, divinely bestowed human 'Free Will' accounts for #3 without compromising either #1 or #2.  Now, as Descartes explains, in the Fourth Meditation, God, too, possesses Free Will.  But, God is incorporeal.  Therefore, in this scheme, the source of Free Will can only be Mind, which clarifies why Descartes classifies Will as a species of 'Thinking', even as he opposes it to another species, 'Understanding'.  So, in two respects, his concept of Will is determined by Theological systematic exigency, rather than by perceivable characteristics of actual human motivation, as it is for Aristotle.  Also in contrast, Spinoza denies #3, leaving no need to posit the existence of a 'Free Will' that is separate from what Descartes calls 'Understanding'.
