I have the same problem as TB - I get bits and pieces that seem to make sense, but then they get buried in incomprehensibility. There are quite a few areas he's touched on in various posts that interest me - a recent example is his (apparent) stance against Wilson's group selectionism. It's a fascinating topic, but I was terrified of commenting because I knew the response would be both long and totally incomprehensible. Brad seems to know what he's talking about (when I can understand it). I just wish there was some way of engaging him in a conversation.
