One but not the Same

Abstract

The paper aims at identifying similarities and differences between two different ways of using the word “true”, on the one hand when it is used to refer to a property of what we say or believe, here called “words’ truth”, on the other when it is used to refer to a feature of things in general (as when we say “he is a true friend”), here called “things’ truth”. I will point out how such similarities and differences may be usefully described starting from the feature of truth called “transparency” which is often considered as exclusively pertaining to words’ truth. The upshot of the paper will be that Aquinas was right in considering the two kinds of truth as species of the unique genus “adaequatio rei et intellectus”, but that this conclusion can be reached without any commitment to the ideology (in the Quinean sense) of the correspondence theory of truth.
