This article discusses the tension between social relationality and self-relationality central to Heidegger’s ontology of Dasein and the possible ways of reconciling this tension. Arguing that this is a tension between communicability and existential commitments, the article poses the question: How are existential commitments responsive to communication? After problematizing the quasi-Kantian and communitarian ways of settling the tension, the article uses Heidegger’s early reading of Aristotle to develop a third hermeneutic model of ethical relationality according to which existential commitments are (...) shareable in communication, since ethos – the existential posture towards the good – arises out of pathos that exposes Dasein to coexistence. The account of ethical relationality found in Heidegger’s interpretation of Aristotle thus takes the world to be a shared and dynamic ontological condition and emphasize that the world constitutes selfhood in a way that is constantly at stake in ethical communication.
