I read On Human Nature because I've never read E.O. Wilson and wanted to better understand what he's about. I'm not a scientist; far from it.But this is pretty easily understandable to the layman. I think I'd have been aided by greater knowledge of the field in order to grasp the impact of social biology, but the language and concepts weren't over my head.What I love about this is that it's a 'big idea' book. I love that experience of the eyes reading along, catching a phrase that sends the brain off wandering somewhere else while the eyes keep covering pages. And then having to go back and find out where it was that your eyes and brain chose separate paths. Wilson provides several of these opportunities.
