Tool and nature. The passage builds a contrast: a made thing (ὄργανον, ἐργαλεῖον, σκεῦος) is "well" if it does its work — but its maker (ὁ κατασκευάσας) is already outside it (ἐκποδών), detached from the product. In TERMthings of nature (τὰ ὑπὸ φύσεως συνεχόμενα) it is otherwise: the building power (ἡ κατασκευάσασα δύναμις) does not leave its product but abides within (ἔνδον). The governing discipline is desire (to live by the will of that power); the sustaining one is assent (to reverence and acknowledge it).

The immanent maker. Here lies the watershed between craft and Stoic physics: the god-Logos is not an external Demiurge but an inner formative might that "holds together" (συνέχειν) its creations. Therefore it is all the more to be TERMreverenced (αἰδεῖσθαι): it has not departed, it is here.

To live by its will. The practical upshot: "if you keep yourself according to the will (βούλημα) of this power, everything for you is TERMaccording to intelligence (κατὰ νοῦν)." DOGMATo live according to nature = to attune oneself to the inner will of the formative Logos; then discord vanishes. And a cosmological rhyme: "so too the Whole holds its own DOGMAaccording to intelligence" (τῷ παντὶ κατὰ νοῦν τὰ ἑαυτοῦ): the order of the microcosm (my life by nature's will) mirrors the order of the macrocosm (all in the world is rationally arranged).

Parallels. DOGMALiving according to nature as concord with the will of the Whole; DOGMAprovidence (all κατὰ νοῦν); the immanence of the Logos — 06-01 (the reason governing the Whole); Med. 8.50; 10.1; cf. the image of the power "holding together" (συνέχουσα) — 4.40. The reverence of the inner principle — cf. TERMαἰδώς toward the ruling part in oneself.
