Off-topic, but it just occurred to me that the "dialog" in this article between the author and the "Haskie" dog is a very traditional way of writing pedagogical works. Some historical examples of books written in this way are Galileo's "Dialogue Concerning the Two Chief World Systems" (the one that landed him in hot water), and "The Study of Counterpoint" by Johann Joseph Fux (also in the 17th century). A small excerpt from "The Study of Counterpoint": >Joseph.— Why did you leave out B between A and C? > Aloys.— Because it has no perfect fifth and therefore cannot be the final of a mode -- which we shall discuss more fully in its proper place. Both of these books are written as an entire discussion or argument, as was commonplace in teaching books. I honestly often find myself disliking it, but I think it is a great way to learn for many people.
