Genre and place in the book. A memento mori in the form of self-reproach (the same device as Med. 5.1): "you will soon die — and you are still not…". Death here is not an object of contemplation (as in 04-14/04-21) but a spur: the nearness of the end exposes how little ground has been covered, and demands haste (EXERCISEno-more-delay).
Five unfinished goals. The list is a compact portrait of Stoic maturity ex negativo: (1) ἁπλοῦς — simple, single, without a double bottom; (2) ἀτάραχος — undisturbed (the concept of apatheia); (3) ἀνύποπτος τοῦ βλαβῆναι ἔξωθεν — without suspicion of harm from outside; (4) ἵλεως πρὸς πάντας — kindly to all; (5) τὸ φρονεῖν ἐν μόνῳ τῷ δικαιοπραγεῖν — placing wisdom only in acting justly. An almost verbatim twin of the self-exhortation at Med. 6.30 ("be simple, good, a friend of justice, kind").
Harm from outside. "Not to suspect the possibility of harm from outside" (ἀνύποπτος τοῦ βλαβῆναι ἃν ἔξωθεν) rests on the doctrine that nothing external can harm the good person (no-harm-to-virtuous; cf. 04-08 — where there is no moral hurt, there is no harm). So long as you fear it, the doctrine is not yet internalised.
Wisdom only in just action. The emphatic μόνῳ: the good and wisdom lie only in virtuous (just) action, all else being indifferent (DOGMAvirtue-is-sufficient; cf. Med. 12.1 — "direct the present only to piety and justice").
Why the terms are empty. No lexeme with a card appears in the text: δικαιοπραγεῖν ("to act justly") is not δικαιοσύνη/δικαιότης (the dikaiosyne card declares only that form; cf. the rule δίκαιος ≠ δικαιοσύνη from 04-10); ἀτάραχος is not ἀπάθεια (and the term ἀπάθεια is itself not used in Marcus). Strictly, there is nothing to tag.
The disciplines. The principal one is assent: the condition of the ruling faculty (integrity, imperturbability, the right judgement about harm and about where the good lies). The secondary is action: kindliness to all and just deeds.
Parallels. The memento-mori self-reproach — 02-04; 04-17; Med. 5.1; 12.1 (cf. EXERCISEno-more-delay). Be simple, just, kind — Med. 6.30; 12.1 (cf. DOGMAvirtue-is-sufficient). Nothing external harms the good — 04-08 (cf. no-harm-to-virtuous; dichotomy-of-control).
