This paper considers how the experience of illness fits within Sartre’s account of embodiment in Being and Nothingness. Sartre makes some remarks about illness, but does not develop a full account. I show that the anti‐naturalistic ontological framework in which Sartre’s discussion of the body is placed, which opposes my ‘being‐for‐Others’ to my ‘being‐for‐myself’, imposes a revisionary account of illness, and how Sartre’s model of interpersonal relations affects his view of doctors, and their role in the illness experience. I note (...) and discuss the connection Sartre draws between illness and bad faith. I also point out that recent phenomenologically inspired criticisms of the medical establishment that draw on Sartre’s account of the body are limited by their failure to engage with Sartre’s ontology.
