I have always held a dim view of human nature. In many ways, that is the view out of which my conservatism grows,contra progressives who like to think that we get "better " with time. It is no accident that the belief in the perfectibility of Man comes from the left.
"Man isn't a noble savage, he's an ignoble savage. He is irrational, brutal, weak, silly, unable to be objective about anything where his own interests are involved-that about sums it up. I'm interested in the brutal and violent nature of man because it's a true picture of him. And any attempt to create social institutions on a false view of the nature of man is probably doomed to failure."
