Interpreters generally understand Heidegger's notion of finitude in one of two ways: (1) as our mortality – that, in the end, we are certain to die; or (2) the susceptibility of our self‐ and world‐understanding to collapse – the fragility and vulnerability of human sense‐making. In this paper, I put forward an alternative account of what Heidegger means by ‘finitude’: human self‐ and world‐understanding is non‐transparently grounded in a ‘final end.’ Our self‐ and world‐understanding, that is, begins at the end, and authenticity requires us to interpretively appropriate the full range of this understanding. After laying out this view of finitude, via an analogical appeal to the Socratic account of action and desire in the Gorgias, I discuss its relationship to the two leading views of finitude mentioned above.
