This paper explores two models using which we might understand Heidegger's notion of ‘Eigentlichkeit’. Although typically translated as ‘authenticity’, a more literal construal of this term would be ‘ownness’ or ‘ownedness’; and in addition to the paper's exegetical value, it also develops two interestingly different understandings of what it is to have a judgment of one's own. The first model understands Heideggerian authenticity as the owning of what I call a ‘standpoint’. Although this model provides an understanding of a number (...) of key features of authenticity, it also invites an important objection—which I call ‘the closure objection’—that can be found in, for example, the work of Steven Galt Crowell and Tony Fisher. Although I argue that this objection can be met, the response for which it calls reveals that the feat of authenticity as understood through the standpoint model rests upon a further feat, and one which may itself have a stronger claim to be identified with Heideggerian authenticity. I develop this thought, introducing what I call the ‘all-things-considered judgment model’ of authenticity, the basis of which lies in, among other sources, Heidegger's appropriation of themes from Aristotle's discussion of phronesis. I explain the exegetical benefits of adopting this model and consider some objections that it invites, before closing with a discussion of how the two models understand the notion of ‘a judgment of one's own’.
