Guthrie: Tratado 3,7 (III,1,7) — A opinião estoica do encadeamento das causas

RESTATEMENT OF THE STOIC DOCTRINE, AND THE HERACLITIAN.

7. There remains to be considered the (Stoic) doctrine which, concatenating and interrelating all things among each other, establishes “a single cause which produces everything through seminal reasons.” This doctrine reattaches itself to (Heraclitus’s) which deduces from the action of the universal Soul the constitution and the movements of the individuals as well as those of the universe.

ALEXANDER OF APHRODISIA’S POLEMIC AGAINST THE STOICS.

In this case, even if we possessed the power of doing something by ourselves, we would not be any the less than the remainder of the universe subjected to necessity, because Fate, containing the whole series of causes, necessarily determines each event. Now since Fate includes all causes, there is nothing which could hinder the occurrence of that event, or alter it. If then everything obeys the impulsion of a single principle, nothing is left to us but to follow it. Indeed, in this case, the fancies of our imagination would result from anterior facts, and would in turn determine our appetites; our liberty would then have become a mere word; nor would we gain any advantage from obeying our appetites, since our appetites themselves will be determined by anterior facts. We would have no more liberty than the other animals, than children, or the insane, who run hither and yon, driven by blind appetites; for they also obey their appetites, as fire would do, and as all the things which fatally follow the dispositions of their nature. These objections will be decisive for those capable of apprehending them; and in the search for other causes of our appetites they will not content themselves with the principles which we have examined.
