Abstract

Through a comparison of the phenomenological motif of the alien and the psychoanalytic motif of the unconscious, a critique is advanced against Cartesian dualism, which recurs today in the natural sciences and in the split of the contemporary individual, divided between spirit and nature, the proper world and the alien world, the inner sphere and the outer sphere. It is a matter of thinking of an original subtraction, an absent presence that begins with ourselves, in a slippage that achieves no synthesis.
