ABSTRACT
Bergson’s own dualism might be described, if rather puzzlingly, as one between perception and memory. That the dualism should be expressed not in terms of consciousness on the one hand and an external world on the other but in terms of two activities of consciousness itself is in keeping with the whole spirit of his philosophy, even though I know of no passage where the dualism is described point blank as one of perception and memory. It is between these terms that he insists time after time that there is a difference of kind, not of degree, though there are complications; perception and memory can in a certain sense be equated with matter and spirit respectively (MM, 325), but matter and spirit themselves are said to differ only in degree (MM, 296).
