turning"
Though not in the Burke we read, he does make a point that between Cicero and Augustine, there's a meaningful shift in Rhetoric from "to move" (movere) to "to bend" (flectere). Muckelbauer adding the Presocratic "to turn" makes for an interesting track between the three. Turning and bending both leave the subject in the same "place," but a bent subject is changed while a turned one pivots. Although, I am also open to the possibility that translation from Ancient Greek and Latin to English might be leading me down a less-than-useful path.
