Science fiction, outside of poetry, is the only literary field which has no limits, no parameters whatsoever. - Theodore Sturgeon

Live long and prosper

There is in mankind a deep and desperate necessity to feel superior. In any group there are some who genuinely are superior...but it is easy to see that within the parameters of any group, be it culture, club, nation, profession, only a few are really superior; the mass, clearly, are not.
But it is the will of the mass that dictates the mores, initiated though changes may be by individuals or minorities; the individuals or minorities, more often than not, are cut down for their trouble. And if a unit of the mass wants to feel superior, it will find a way. This terrible drive has found expression in many ways, through history—in slavery and genocide, xenophobia and snobbery, race prejudice and sex differentiation. Given a man who, among his fellows, has no real superiority, you are faced with a bedevilled madman who, if superiority is denied him, and he cannot learn one or earn one, will turn on something weaker than himself and make it inferior. The obvious, logical, handiest subject for this inexcusable indignity is his woman.
He could not do this to anyone he loved.

An ethic isn’t a fact you can look up. It’s a way of thinking.
