Carefully reifying the differential-geometric pushforward and pullback operators as forward and reverse AD clarifies the relationship between forward and reverse AD, and allows the formalization of AD of higher-order functions. We discuss the relationship between the differential-geometric constructs and the usual practice of just lifting all reals to duals, focusing on how they differ in the case of higher-order functions.
