I feel like Quintillian is the first rhetorician we're reading that I would really call a pedagogue. Especially in the sections we're reading- he doesn't defend rhetoric, he just tells people how to teach it. This seems obvious at first, but it's not- if we look closely, there are a lot of things that Quintillian's position in history allows him to take for granted: that there is at least some inherent value in speaking, writing, or reading, that rhetoric is a valid topic of study, that education is important, and that it is necessary to instruct people on the specifics of how to teach (exercises and whatnot). Perhaps it is for this reason that, reading Quint, a lot of his points felt obvious. I believe that makes him an example of an author whose work has been almost fully embraced by our practices in rhetoric (or by my practices, anyway).
