The present investigation develops the notion of sociality based on Emmanuel Levinas’s thought, and proposes an understanding of sociality that resists becoming a common foundation: an un-common sociality which interrupts the reciprocal shared common, and thereby, paradoxically, makes it possible. By engaging in the larger debate on community, this work gives voice to Levinas on the question of community without a common ground, a topic and a debate where he has previously been underestimated. In this way, the aim is to reveal new directions opened up by Levinas’s philosophy in order to think an un-common sociality.
