Thanks for your response, Nick. It hadn't occured to me to call Hitler's sweatiness enargeia (which I usually think of as vivid imagery in language, but why couldn't it be physical?), so thanks for that. I think you put your finger in particular on the problem of writing about Hitler generally--how do you balance the need to get close without falling into the trap of empathizing or even appearing to empathize? It's not a problem I've solved, and probably won't, but it's one I think about a lot. But even as I do, like you, I also worry that we won't learn the lessons.
