Thomas Aquinas has long been understood to have reconciled faith and reason. Typically, he is understood as having provided justification for faith by means of proof, particularly, that the Five Ways prove the existence of God. Under this interpretation, faith becomes a species of justified belief, and the justification for faith rests upon the success of the Five Ways . In this dissertation, I argue that Aquinas' account of faith is not one of justified belief, at least as it is (...) understood in contemporary philosophy. Instead, I argue, faith has its own basis for epistemic "reasonableness"---a reasonableness that does not derive from ordinary evidence nor proof. Rather than requiring evidence accessible to the natural light of reason, Aquinas holds that faith has its own sort of "evidence"---that which results from the light of faith. Aquinas "Aristotelianizes" faith and argues that faith has the Aristotelian epistemic virtue of certitude, and in so doing reconciles faith and Aristotelian reason, at least as Aristotle was understood by Medieval philosophers. This reconciliation resolves important tensions between Aristotelian science and Christian doctrine. Further, I examine three contemporary accounts of what counts as an epistemically "responsible" belief and argue that under Aquinas' account, faith should be counted as rational, and in an important, though modified sense, as justified.

My article critically evaluates five key claims in Kerr’s interpretation of Aquinas’s De Ente et Essentia, ch. 4, proof for God. The claims are: the absolutely considered essence is a second intention, or cognitional being; à la John Wippel, the real distinction between essence and existence is known before the proof; contra David Twetten, Aristotelian form is not self-actuating and so requires actus essendi; the De Ente proof for God uses the Principle of Sufficient Reason; an infinite regress must be (...) eliminated before concluding to God. This author wonders if these questionable claims are traceable to the mindset of analytic philosophy which values precision and discreteness and so can fail to appreciate crucial paradoxes in Aquinas’s metaphysics.

A number of recent discussions of atheism allude to cosmological arguments in support of theism. The five ways of Aquinas are classic instances, offered as rational justification for theistic belief. However, the five ways receive short shrift. They are curtly dismissed as vacuous, arbitrary, and even insulting to reason. I contend that the atheistic critique of the Thomistic five ways, and similarly formulated cosmological arguments, argues at cross purposes because it misrepresents them. I first lay out the context, intent and (...) structure of Aquinas’ arguments, then show in what way recent discussions misrepresent them, and finally conclude with a comment on metaphysical orientation, which I take to be central, not only to a proper understanding of the Thomistic five ways but generally to the debate between atheism and theism on the existence of God.
