Self-Sublimation, Self-Overcoming, Species

Nietzsche's concept of Self-Sublimation is a special case of that of the Will to Power, in its Self-Overcoming mode, in particular.  Such a concept is unthinkable on the basis of the Prudentialism to which Freud subscribes, i. e. of the combination of the Pleasure Principle, and the Reality Principle which re-directs it to acceptable gratifaction.  Notable in this textual sequence--188-9 of Beyond Good and Evil--is one of the rare attributions in Nietzsche's oeuvre of the Will to Power to the development of the species, rather than to the behavior of individual members.
