A hymn of ones. Marcus's fullest formula of Stoic unity — an anaphora of seven "ones": one cosmos, one god, one substance, one law, one common TERMlogos, one truth, one perfection. It opens with the thesis of DOGMAuniversal interweaving: πάντα ἀλλήλοις ἐπιπλέκεται — "all things are woven into one another," and σύνδεσις ἱερά — "the bond is holy." Physics here acquires a liturgical register: the world's connectedness is not merely a fact but a sacred thing; to violate it (to secede, to be at enmity) is not an error but a sacrilege. The qualifier σχεδόν τι ("hardly anything") is Marcus's characteristic honesty: even a hymn he states with an observer's caution.
συγκοσμεῖ — co-adorns. All has been "ranged together" (συγκατατέτακται) and "jointly adorns the same cosmos": the verb plays on the double sense of κόσμος — "order" and "ornament." Every thing is at once a structural member and a touch of the adornment; there is no unsightly remainder. Cf. 06-38 (τονικὴ κίνησις, σύμπνοια — all things "breathe together"), 4.40 (the world as one living being), 12.30 (one sunlight, one substance, one reason).
One law — one city. The link "DOGMAνόμος εἷς" introduces into the physical hymn its political consequence: in 4.4 a syllogism is drawn from the community of logos — common reason → common law → fellow-citizens → the world as a city (κοινὴ πόλις). Here the same chain is given in compressed form, as a single link between "one substance" and "one logos." The closing "one truth" and "one perfection" extend the unity into epistemology and ethics: for beings of one kind, partaking of one logos, there can be neither "private truths" nor different measures of perfection. The discipline is desire: a contemplation of connectedness that dissolves the sense of anything being alien.
