 So it's been a long time since I'd read it really from start to finish. And I had never really read it from start to finish with a view to thinking seriously about its philosophical argument. But when you're reading very slowly sentence to sentence with a group of deeply engaged students, you can't help but do that. And so the fact that it does convey a coherent philosophical view is what came through to me. And so I was sort of bowled over by the coherence of the view and by how powerful it is.
