Do not peer into others' ruling parts. The opening imperative is against distraction: μὴ περιβλέπου ἀλλότρια TERMἡγεμονικά — "do not look around at others' ruling parts." Do not pry into what is in another's head (cf. 02-08 — unhappy is the one who does not attend to his own soul; 03-04 — do not spend life on thoughts about others; 04-18 — how much leisure he gains who does not look to his neighbor). Instead, a straight look (κατ’ εὐθύ) to where TERMnature leads: a double nature — that of the Whole (through what happens to me: the material of desire) and my own (through what must be done: the material of action).
A hierarchy by constitution (κατασκευή). The axiom of function: each does "what follows from its constitution" (τὸ ἑξῆς τῇ κατασκευῇ). The cosmic subordination: the irrational for the sake of the rational (lower for higher), but the rational DOGMAfor one another's sake (ἀλλήλων ἕνεκεν): the summit of the chain of ends is not egocentric but reciprocal. Hence three priorities in "man's constitution," laid out along the three disciplines:
- προηγούμενον — TERMthe social (τὸ κοινωνικόν): the leading thing in the human constitution — the discipline of action.
- Unyieldingness to the body (ἀνένδοτον πρὸς τὰς σωματικὰς πείσεις): DOGMAthe rational motion "circumscribes itself" (περιορίζειν ἑαυτήν) and does not let itself be overpowered by the sensory and impulsive motions — they are "animal" (ζῳώδεις); the νοερά "means to hold first place" — the discipline of desire.
- ἀπρόπτωτον καὶ ἀνεξαπάτητον — "un-precipitate and undeceivable": not to lurch into hasty assent, not to be taken in — the discipline of assent.
Holding fast to these three. The conclusion: the ruling part, "holding to these (τούτων ἐχόμενον), let it complete the straight line (εὐθεῖαν περαινέτω) — and it has what is its own" (ἔχει τὰ ἑαυτοῦ). The image of the straight line — 7.12 (ὀρθός), 03-05 (upright, not held upright): to fulfil the three priorities just is to hold one's course without swerving after others' ruling parts. The governing discipline is action; the sustaining one, assent.
