Try reading #15 again. If you need help with some or all of it, don't be afraid to ask.
Try reviewing Pinker's appearance on Dawkin's the genius of Charles Darwin and his appearance on newsnight as referenced.
Vis my usual complaint with Pinker.
It's his use of the statistics and the obtaining of them that is his trouble.
Since he goes back to middle ages where statistics were not scientifically kept but I think you are aware of the issues there.
He uses them to make a philosophical point and claim above and beyond even the realms of social science.
Any way it would be nice to hear him justify his methodology and claims in a context contradictory to his thrust about the enlightenment.
