I argue that Sartre's Transcendence of the Ego draws on Kant's theory of spontaneity to articulate its metaphysical account of consciousness's mode of being, to defend its phenomenological description of the intentional structure of self‐consciousness, and to diagnose the errors that motivate views of consciousness qua person or substance. In addition to highlighting an overlooked dimension of Sartre's early relation to Kant, this interpretation offers a fresh account of how Sartre's argument for the primacy of pre‐personal consciousness works, and brings (...) the extent of his proximity to idealist models of mind into greater relief. It also affords Sartre the resources to respond to criticisms that his account of self‐consciousness relies on a spurious distinction and that his view of freedom cannot explain how consciousness is conditioned by its world.
