La Nozione di Verità tra Naturwissenschaften e Geisteswissenschaften.

The notion of truth is a central notion in most of the sciences, whether we refer to the Human Sciences, but also to the Natural Sciences. However, it transcends the ambit of any particular discipline, its analysis takes the form of a properly philosophical analysis. An analysis that have to be 'analytical' and 'critical' at the same time: it have to examine its limits and possibilities, formalizing them. it seems possible to assert that truth is co-originary with philosophy: philosophy starts from its intrinsic need to seek the first principle, in Heideggerian terms to un-veil the origin, to clarify the concept of truth. Not by chance the word “truth” corresponds, in ancient Greek, to ἀλήθεια: literally it can be translate as disclosure; “unveiling” which denotes the activity of the same philosophy: clarifying, unveiling what is hidden. This dissertation aims to analyze the notion of truth by a formal point of view, using the results of formal logic and the position of Martin Heidegger (strongly influenced by the concept of ontological difference).
