A cosmic power — and ours. An analogy of capacity: as TERMthe nature of the Whole (the manuscripts have ἡ τῶν λογικῶν φύσις, "the nature of rational beings"; Rogovin and Long read τῶν ὅλων) has endowed rational beings with all their other powers, so it has given this one too — to turn a hindrance to one's own use. The model is the cosmos itself: "everything that resists and opposes" (πᾶν τὸ ἐνιστάμενον καὶ ἀντιβαῖνον) it "turns about" (ἐπιπεριτρέπει), TERM"orders into fate" (εἰς τὴν εἱμαρμένην), and makes a part of itself. No resistance stays outside the world-order — it is absorbed as material.
The obstacle as fuel. Hence the ethical conclusion: the rational animal "can make every obstacle (κώλυμα) its own material (ὕλη) and use it" — for the very end it was set upon (ἐφ’ οἷον ἂν καὶ ὥρμησεν). This is the exact formula of MOTIFthe fire that turns a hindrance into its food (4.1; 5.20 — "that which is a hindrance is made a furtherance to an act; and that which is an obstacle on the road helps us on this road"). A pair to 8.32: there a thwarted act is replaced by another; here the metaphysical guarantee is given — the power to transform the hindrance is inherited from the nature of the Whole, which does just this with everything. DOGMAAcceptance is thereby not passive: to accept is to convert into the material of virtue. The governing discipline is desire (to accept the hindrance as material), the sustaining one action (to put it to use).
