The denigration of anti-fragility is in a sentence that dominates Summa Theologiae; one variant: "Agen autem non movet nisi ex intentione finis", an agent does not move except out of intention for an end; in other words THAT AGENTS ARE SO RATIONAL THEY KNOW WHERE THEY ARE GOING.& who dominates this discourse on teleology? Not "the philosopher" (Aristotle), but the more pervasive "commentator", IbnRushd aka Averroes.
