that there is nothing wrong with human nature, only something wrong with human
culture- By nature, humans are as harmless (which is not to say "noble" in any romantic sense) as skunks, bears, or wolves. True, human culture has been created only
by humans- but firstly, all humans have not contributed to it equally (it's disproportionatley the work of a small ruling class- what Gramsci talked about re: hegemony) and secondly- it's a snowball effect. Take some primates that ordinarilly act in a way that works for them, and put them in a setting that's totally incompatible with their native biological inclinations- one in which the social groups they organize themselves into are fragmented, torn apart, and dissolved on a regular basis, in which they follow not whatever rules work for them, enforced if at all by a "cheif" alpha who stays in power through a basic group consensus, but rules that are imposed by a remote economic elite, and in which the young are not allowed to explore and learn about their surroundings naturally but are forced to spend the bulk of their time in buildings sitting down learning rote facts- and soon you will have a bunch of very dysfunctional chimpanzees.
Fear and insecurity are natural, are human, are actually quite healthy responses to many situations- I would argue that it is not by shedding these, but by shedding economic class (which will of course be a long battle against entrenched interests- I don't expect I'll live to see it) that we'll be able to live in a socially healthy and ecologically sustainable way. And then, well, maybe as a species we'll still die with the sun, or maybe not. Who knows?
And I tend to agree with Walt Whitman- we already are divine. We come from the beautiful uncut hair of graves.
