Techne and Superman

Superficially, Nietzsche's Superman and the Superman of American fiction are only nominally related--the superiority of the former is Psychological, while that of the latter is Physiological.  However, one more direct link is that one of the obstacles that Nietzsche's character overcomes, via Self-Affirmation, is "the Spirit of Gravity", expressed by conformist Morality.   So, it, like its correlate, in a sense can 'fly'.  But, a third type of flying, an actual one, arises in the decades in between the first appearances of the other two--that of a flying machine, which overcomes Physicist Gravity.  So, perhaps if Nietzsche were to live a few more decades, he might have witnessed a more profound overcoming, over a force long conceived to be insuperable, ascribable to not the merely Psychological Self-Affirmation, but to the Techne that empowers it, a Knowledge that, too, is beyond conformist Morality.
