I'm speaking on human nature and socialism next week. Could be interesting. I'll post up the gist of it afterwards. Not done one of these for a while so it'll be interesting to see if I can remember how to speak to a room half-full of very argumentative people. Come along if you've got nothing better to do, why don't you?
I've not finalised what I'm going to say yet, but it'll probably have a bit of Vygotsky, a bit of John Molyneux, a splash of Wittgenstein, and some Toy Story 3 for good measure.
