The aim of this paper is to offer a novel reconstruction of Sartre's theory of motivation. I argue for four related claims: (a) Sartre's theory of motivation revolves around the Schelerian-inspired notion of affectivity and the peculiar way affectivity provides us access to evaluative properties of the objects in our environment; (b) according to Sartre, the structure of intentional action, and in particular the act of choice and commitment to projects, is inextricably linked with “affectivity”; (c) the inextricable link between intentional action and affectivity is to be analysed in terms of the fundamental structure of consciousness as being self-present thus making the agent non-positionally aware of her choices and commitments; (d) an agent is motivated to act when her affective disclosure of value is in part constituted by the awareness of her commitments to relevant projects.
