Übermensch as a goal

Zarathustra first announces the Übermensch as a goal humanity can set for itself. All human life would be given meaning by how it advanced a new generation of human beings. The aspiration of a woman would be to give birth to an Übermensch, for example; her relationships with men would be judged by this standard.
Zarathustra contrasts the Übermensch with the last man of egalitarian modernity, an alternative goal which humanity might set for itself. The last man appears only in Thus Spoke Zarathustra, and is presented as a condition that would render the creation of the Übermensch impossible.
According to Rüdiger Safranski, some commentators associate the Übermensch with a program of eugenics. This is most pronounced when considered in the aspect of a goal that humanity sets for itself. The reduction of all psychology to physiology implies, to some, that human beings can be bred for cultural traits. This interpretation of Nietzsche's doctrine focuses more on the future of humanity than on a single cataclysmic individual. There is no consensus regarding how this aspect of the Übermensch relates to the creation of new values.
