The notion of corporeal difference lies at the heart of political phenomenology. It refers to the existential situation of a bodily ambiguity which is characterized by a threefold tension: between the lived body (Leib) and the material/corporeal body (Körper), the bodily self and the exposure to others, and between being situated in the world and positioned towards the world. Ambiguity is understood as a fundamental ontological category of existence; it is essential and irreducible. However, the ambiguity of the corporeal difference can be disturbed in its engagement in the world and with others. This creates an awareness of the body as finite, material object and an in-difference to the intercorporeal and intersubjective self. In the end, the talk argues for a concept of corporeal non-indifference that recognizes a sensitivity to human practices of plurality and justice.
