Vegetative Psyche and Sexuality

The three traditional divisions of the human Psyche can be conceived as interacting as follows--the Vegetative reproduces Life, e. g. replacement cells, the Locomotive secures the means to that reproduction when not immediately available, e. g. walking to where food can be gotten, and the Calculative determines the best means to that end.  Accordingly, the Vegetative is the primary motivator of behavior.  Now, Aristotle classifies sexual reproduction as Nutritive, i. e. his Vegetative, and, so, might accept Freud's concept of it as a fundamental Psychological principle.  However, granting that, the Aristotelian challenge to Freud is to explain the privileging of sexual reproduction over other Vegetative processes, e. g. eating, for which Freud seems to have no clear answer.  One explanation might be that the privileging reflects a general affluence in which the other needs are routinely satisfied, thus exaggerating one that has been long repressed on predominating theological grounds.  That explanation also exposes the distortion involved in Marcuse's reduction of the dehumanization of the worker to the repression of the sex drive.
