Things are meaningful to us in terms of their use in certain contexts, which are defined by social, that is mainly practical, norms. However, all of these norms are radically contingent. Their contingency is revealed in the fundamental phenomenon of Angst, in which all norms fall away and beings show up as nothing in particular, in their essential meaninglessness. (Contrary to some existentialist interpretations of Heidegger, this does not mean that all existence is absurd; rather, it means that existence always has the potential for absurdity.) The experience of Angst reveals the essential finitude of Dasein.
