Genre and place in the book. The second passage of Book II, coming immediately after the programmatic morning meditation. If 02-01 prepares one for the meeting with others, 02-02 prepares one for the meeting with oneself: what am I, once social roles and habitual self-identifications are stripped away. The passage is the master-key of the whole corpus on Hadot's reading: its closing three imperatives cover all three disciplines (assent, action, desire) — which is why it became the basis of La Citadelle intérieure.

Structure of the argument. It unfolds in two movements — analytical and normative.

1. Analytical. "Whatever this thing is that I am, it is TERMa scrap of flesh, TERMa little breath, and the TERMruling part." A threefold division marked by deprecatory morphological diminutives (σαρκία, πνευμάτιον, then ὀστάρια, πλεγμάτιον). Each part is then stripped to its material:

• σαρκία → λύθρος καὶ ὀστάρια καὶ κροκύφαντος (the exercise of EXERCISEphysical definition, the image MOTIFflesh-as-network);
• πνευμάτιον → ἄνεμος ἐξεμούμενον καὶ ῥοφούμενον ("a breath, exhaled and inhaled again");
• what remains is τὸ ἡγεμονικόν — the only thing to which the "I" can be applied (see the doctrine DOGMAself-is-hegemonikon).

1. Normative. "You are an old man" (γέρων εἶ — the posture of EXERCISEthe memory of death). Three μηκέτι ("no longer"):

• μηκέτι δουλεῦσαι — let the ruling part no longer be enslaved (the general posture of DOGMAthe dichotomy);
• μηκέτι καθ' TERMὁρμὴν ἀκοινώνητον MOTIFνευροσπαστηθῆναι — the discipline of action: do not let an unsocial impulse twitch you like a puppet on strings;
• μηκέτι τὸ TERMεἱμαρμένον … δυσχερᾶναι … ὑπιδέσθαι — the discipline of desire: be not vexed at your present lot, nor fear what is to come (DOGMAamor-fati).

All three disciplines in a single passage. This is the reason Hadot chose precisely 02-02 as the "map" of Marcus's philosophy. In one paragraph:

• assent: correct self-identification (I am only the TERMruling part);
• action: the social quality of the TERMimpulse;
• desire: acceptance of TERMfate.

Stylistics. Deprecatory morphology: σαρκία, πνευμάτιον, ὀστάρια, φλέβια, πλεγμάτιον — five diminutives in a single sentence. The method is not rhetorical but analytical: the morphology itself draws the line between "I" and "not-I." In parallel runs the verbal chain νεῦρα → νευρόσπαστον: the material of the body (sinews, veins) and the material of the puppet (the strings on which it is twitched) are the same word; the only question is who is pulling whom (see the images MOTIFflesh-as-network and MOTIFpuppet).

A terminological subtlety. In Stoic orthodoxy the human being is bipartite: body and pneuma (where rational pneuma ≡ ἡγεμονικόν). Marcus's triad "flesh / breath / ruling part" is not a doctrinal division but a methodological move: to isolate the dense matter (σάρξ), the subtle matter (πνεῦμα in the narrow sense of "breath"), and the rational element proper (ἡγεμονικόν). The triad recurs at Med. 3.16 and 12.3 — it is to be read as a meditative device, not as an ontological scheme.

Parallels. The programmatic formula "what belongs to me" — Epictetus Disc. 1.1 and Ench. 1; the famous «ψυχάριον εἶ βαστάζον νεκρόν» ("you are a little soul carrying a corpse"), which Marcus ascribes to Epictetus at Med. 4.41. The posture "as one already dying" — Sen. Ep. 26 ("the daily preparation for death"), Ep. 76, Ep. 101; Plat. Phd. 64a (philosophy as μελέτη θανάτου, the practice of dying). The image νευρόσπαστον — Plat. Leg. 644d–645a (but positively in Plato: god pulls the "golden string"); in Marcus, the inversion.
