 Since [Aristotle’s] purpose is to inquire about the first mover, he begins by inquiring about motion, whether it is eternal or innovated, that is, according to the genus, and that which precedes this treatise, either is necessary to this section, or is for the sake of better. And when he said “Whether motion”, he did not mean any specific (proprium) motion, but he wanted to know whether those motions existent in the parts of the universe came to be, after no part of the universe moved at all, etc. (LC 338FG TC1; MC Glasner 94–95)
