 So much, I think, of reading is that moment, like Arun said, of happening kind of in your head, figuring out whether you're digesting something. I don't want to say correctly, but maybe in the way that the author intended you to get it. And teaching, I think, is really kind of doing that move of holding a mirror up to the class to borrow a phrase from a critic whose name I'm forgetting awfully and help them understand what they're thinking, help them kind of work through all those miscellaneous threads and put them together. And I think hypothesis kind of allows you to do that, allows you to kind of bring those voices together, work through them. So I do think there is something vital that happens when you're having these conversations in live time, in a sense, while you're reading. I think that changes it entirely.
