It is in the same way theoretically understandable that mental illness may, in its turn, be linked with some bodily accident; consciousness projects itself into a physical world and has a body, as it projects itself into a cultural world and has its habits: because it cannot be consciousness without playing upon significances given either in the absolute past of nature or in its own personal past, and because any form of lived experience tends towards a certain generality whether that of our habits or that of our 'bodily functions'.
