According to Heidegger's Being and Time, social relations are constitutive of the core features of human agency. On this view, which I call a ‘strong conception’ of sociality, the core features of human agency cannot obtain in an individual subject independently of social relations to others. I explain the strong conception of sociality captured by Heidegger's underdeveloped notion of ‘being-with’ by reconstructing Heidegger's critique of the ‘weak conception’ of sociality characteristic of Kant's theory of agency. According to a weak conception, (...) sociality is a mere aggregation of individual subjects and the core features of human agency are built into each individual mind. The weak conception of sociality remains today widely taken for granted. I show that Christine Korsgaard, one of the most creative contemporary appropriators of Kant, operates with a weak conception of sociality and that this produces a problematic explanatory deficiency in her view: she is unable to explain the peculiar motivational efficacy of shared social norms. Heidegger's view is tailor made to explain this phenomenon. I end by sketching how Heidegger provides a social explanation of a major systematic concern animating Korsgaard, the concern with the importance of individual autonomy and answerability in human life.

How can we understand the phenomena of loss and mourning in the Heideggerian framework? There is no established interpretation of Heidegger that gives an elaborate account of the phenomena of loss and mourning, let alone gauges its importance for our understanding and assessment of authentic existence in Heidegger. This paper attempts to do both. First, I give a detailed exposition of Heidegger’s analysis of the phenomena of mourning and loss and show that Heidegger’s analysis of mourning in his early and (...) late work is strikingly in line with his collectivist understanding of Being-with. This demonstrates, contrary to what some of his proponents argue, that Heidegger does not follow the kind of dynamic understanding of Being-with that places the other within fine-grained spaces of possibility. Second, with reference to Heidegger’s existential philosophy, I construct a phenomenology of mourning and grief. Though Heidegger himself fails to explain the relationships in which one mourns after a close other, we can develop a unique phenomenology of mourning with reference to Heidegger, which shows that each loss is singular and can be equiprimordial with one’s own death in opening one to the possibility of an authentic existence. In this new understanding of authenticity, loss is regarded as a powerful force, akin to death, in leading one toward their self-owned existence. (shrink)
