This paper is about the Bergsonian synchronization of the perpetual present or memory with the passing present or the body. It shows how forgetting narrows and focuses consciousness on the needs of action and how motor memory allows the imagining of the useful side of memory. The paper highlights the strength of Bergson’s analysis by respectively confronting classical theories of memory, the highly regarded perspective of the phenomenological school, Deleuze’s interpretation of Bergsonism, and Sartre’s theory of mental imagery.
