Freud and Nietzsche: Where's the Vulnerability?...that other 1/2 of our Nature?

Where Nietzsche sees the perversion of the authentic human instinct to express its will as occurring at the moment where individuals subjugated their autonomous powers in the form of contracts with each other, the psychological insights of Sigmund Freud become relevant. In Future of an Illusion, Freud sites that such a contract between individuals would constitute a society and that all societies are “built up on coercion and renunciation of instinct.” As implied by Nietzsche, and made explicit by Freud, societies, by their very definition, force their constituents to renounce their instinctual drives by subjugating personal autonomy to an external will. Freud’s psychoanalysis contends that the act of subjugation by society is accomplished through a “prohibition,” which is a regulation that disallows the “satisfaction of an instinct.” When an instinct is not allow to be satisfied, it “frustrates” the individual leading to conditions of “privation” which are internalized as “kernels of hostility toward civilization.” Though Nietzsche’s polemic devices are intended to warn humanity that it risks sterilizing its own will to power, thus providing for its own extinction, he can also be seen as agreeing with Freud in that, underneath the centuries of synthetic moral practice, the future health of humanity depends on the ability for a generation of human animals to “conquer God” through the work of the same psychological devices that subjected us to him. Freud and Nietzsche essentially want the same thing. Freud, too, would like to free humanity from its slave-like adherence to religious morality by absolving the human psyche in the realization that religion, and god, are psychological illusions.
