Why I cringe when someone says "Human Nature"

It's not because such a thing couldn't exist, it almost certainly does. There is nothing magic about our species, after all, we are just a strange electric topology that dreams. No, I cringe at the phrase because it's forever bandied about as if "human nature" could be contained in a slogan, an axiom, maybe a philosophy. This is absurd. Human nature is the novel of novels, the story of billions of people over the course of thousands of years. It is the phase space of every story ever written.
