facticity

This chapter explores the complex relationship between the body and consciousness, distinguishing between the body as it is experienced from within (being-for-itself) and the body as an object perceived by others (being-for-the-Other). Sartre argues that the body cannot be fully understood by merging these two perspectives, as they exist on different ontological levels, and critiques the reduction of bodily experience to purely physical or external descriptions. He also challenges traditional philosophical views, such as Cartesian dualism and the notion of 'double sensation,' emphasizing the irreducibility of the lived body to an objectified body.
