This is good - I like 'devil's dictionaries' wherever they appear.
"Human nature: Fantasy. Fictitious entity, like Santa Claus or the tooth fairy or the free lunch. Humans have no nature, only culture; we can learn to fly, or live in the ocean, or echolocate, or pick things up with our trunks, if we will only concentrate."
I love this.
Glad you like it! Especially the human nature one. I did that, and I have to admit, it still makes me snicker.
Brilliant website - this article (http://www.lrb.co.uk/v25/n03/berr01_.html) examining Dawkins, Hamilton and the "Red Queen Process" is the best explaination I've yet seen for the existence of sex and altruism.
