I’ll make it easy.
The ubermensch is an elite psychopath.
The EP only cares about furthering his (or her) own interests, his own freedom, health, happiness, wealth and power, and he has the smarts, and the strength, both physical, and emotional, to further them tremendously, he doesn’t care about other people, except for perhaps his immediate family.
He treats himself as an end, others as means.
While he may lie to others, he’s true to himself.
He may help others, but only insofar as he profits from it.
He enjoys the fine things in life, fine art, literature, music, clothes, food, wine and cars.
It doesn’t matter what career he has, so long as it’s something he enjoys and is good at (it’s more about how he approaches it than what it is).
He may be a brain surgeon, a criminal or even a janitor, but whatever he gets into, so long as some unforeseeable accident doesn’t befall him, he’ll rise to the top or near it.
If he’s a janitor, within a decade or two he’ll have his own janitorial company with dozens, hundreds or thousands of employees under him, whom he’ll have no loyalty to.
EPs are born, you either have talent and tenacity, or you don’t.
You can develop them, but you must have a lot to develop to begin with.
Nietzsche didn’t give step by step instructions on how to develop them, his only point was that people with them needn’t let things like God, democracy, human rights, liberty, equality or nation keep them from furthering their own interests ruthlessly.
A thing that seems to elude some people is, EPs will never tell the people what they are.
For them, it’s best the little people think highly of them, that they’re God fearing people, champions of democracy, human rights and so on, that their power mostly serves these ends.
Today’s EPs wear the emblems of the people, just as they have for centuries, but behind closed doors, with family and other EPs, they take off their masks, and engage in all manner of sordid conversation, and activities, the likes of which the vast majority of people can’t imagine.
Only a barbarous elite that doesn’t mean to rule for very long, like the sort of elites that ruled during the Greek or European dark ages, or the sort of elites that rule Africa today, reveals to the people exactly who they are, but even sophisticated elites can’t help but drop a few hints from time to time.
Closely related to the elite psychopath is the elitist.
The elitist, unlike the psychopath, is sometimes capable of caring for others besides himself (and his immediate family), on some level, but not much about people he considers beneath him, only about people he believes are on his level, and he believes he’s on a much higher level than most.
For him, most people are subhuman.
