 Furthermore, there is a significant difference between Aristotle’s overviews (which we know much better than those of Theophrastus, so for the sake of clarity one may restrict oneself to Aristotle) and the corresponding passages and sections in Aëtius and his family. Aristotle’s purpose was to make a choice and to find a solution, and many later authors also wanted this. But numerous chapters in the Placita literature when taken at face-value seem to make a decision impossible, because the bald diaeretic contrast between the tenets listed in the lemmata results in a logjam, or diaphonia (‘discordance’), as the ancient Skeptics called it. It might be concluded from this stalemate that the only remaining option is to suspend one’s judgment. It was at the time impossible, for instance, to find out whether there is one cosmic system, or more. It is an attractive idea that at least part of the material (in the course of time naturally updated by the inclusion of post-Aristotelian tenets) was adapted by Academic Skeptics to induce the tranquillity of mind which follows upon suspension of judgment.
