Abstract

THOMAS AQUINAS IS WELL-KNOWN for having defended the view that truth consists of an adequation between the intellect and a thing. Perhaps no discussion of this within his literary corpus is better known than that offered in qu. 1 of his Disputed Questions on Truth. Even so, in addition to describing truth as an adequation of the intellect and a thing, he there considers a number of other definitions. Most importantly, he develops a notion of truth of being along with truth of the intellect. As various scholars have pointed out, prior to Thomas's time two general traditions regarding the nature of truth had already appeared. One is heavily neoplatonic and emphasizes truth of being. It was known to Aquinas especially through the writings of Augustine, Anselm, and Avicenna. The other, more Aristotelian, stresses truth as an adequation of mind and reality, or truth of the intellect. Both of these traditions deeply influenced Aquinas's own thinking, as we shall see. But he could and did appeal to a variety of earlier definitions of truth in developing his own view, and this suggests that the two traditions were not so opposed to one another in Thomas's mind as one might think.
