  Aquinas’ balanced formula “equation of thing and intellect” is intended to leave room for the idea that “true” can be applied not only to thoughts and judgments but also to things or persons (e.g. a true friend). Aquinas explains that a thought is said to be true because it conforms to reality, whereas a thing or person is said to be true because it conforms to a thought (a friend is true insofar as, and because, she conforms to our, or God’s, conception of what a friend ought to be). Medieval theologians regarded both, judgment-truth as well as thing/person-truth, as somehow flowing from, or grounded in, the deepest truth which, according to the Bible, is God: “I am the way and the truth and the life” (John 14, 6). Their attempts to integrate this Biblical passage with more ordinary thinking involving truth gave rise to deep metaphysico-theological reflections. The notion of thing/person-truth, which thus played a very important role in medieval thinking, is disregarded by modern and contemporary analytic philosophers but survives to some extent in existentialist and continental philosophy.
