Eugenics and Superhumanism

Only barely inferrable from the texts is the influence of the concept of Human Eugenics on the arc of Nietzsche's oeuvre.  It is clearly relevant to his projection of a transition from Human to Superhuman, and it explains the supplanting of the Will to Live by the Will to Power as his elucidation of the Dionysian principle.  Indeed, he is aware that the mastery of the former by Eugenic techniques might constitute not a transcendence of a Species drive to propagate itself, but, to the contrary, evidence that Will to Power, not Will to Live, has been the true character of that drive all along.  Eugenics thus distinguishes Nietzschean from Darwinian Superhumanism.
