  Heidegger's analysis of truth also countenances a third manifestation of the phenomenon, one that is perhaps best characterized as being located between original truth and propositional truth. This intermediate phenomenon is what might be called Heidegger's instrumental notion of truth (Dahlstrom 2001, Overgaard 2002). As we saw earlier, for Heidegger, the referential structure of significance may be articulated not only by words but by skilled practical activity (e.g., hammering) in which items of equipment are used in culturally appropriate ways. By Heidegger's lights, such equipmental activity counts as a manifestation of unconcealing and thus as the realization of a species of truth. This fact further threatens the idea that truth attaches only to propositions, although some uses of language may themselves be analysed as realizing the instrumental form of truth (e.g., when I exclaim that ‘this hammer is too heavy for the job’, rather than assert that it has the objective property of weighing 2.5 kilos; Overgaard 2002, 77; cf. Being and Time 33:199–200).
