The investigation of concept of “true” and “false” has long privileged in contemporary philosophy apophantic truth, that is, the truth of dicta (sentences or propositions). To which entities, though, beyond dicta, the predicate ‘true’ pertains? This paper sheds a light on the less frequently investigated cases where we speak of a truth of things, or res. We say, for instance, that a 17 euros banknote is not a true banknote, or that a true soldier ought to be brave. The paper, (...) thus, distinguishes, beside the concept of de dicto (apophantic) truth, the concept of de re truth and two of its subspecies: eidological truth and idiological truth. (shrink)
