Genre and place in the book. After the philosophical culmination of 02-11 — the longest passage of Book II, with the theistic dilemma and the definition of ἀδιάφορα — Marcus shifts to the genre of meditative prompts. These are five self-standing question-prompts, each a separate object for analytic work. By form they resemble the working notes of a philosopher in practice: not a developed argument but a list of topics to return to in turn in a quiet moment. The genre is close to Epictetus' Διατριβαί in their compact formulations, but more interior — Marcus is not teaching here, he is reminding himself what he needs to think through.

Structure — five prompts. Each opens with πῶς / οἶα / τί / τί / πῶς (how / what kind / what / what / how):

1. πῶς πάντα ταχέως ἐναφανίζεται — "how quickly all things vanish": the bodies in the cosmos, the memory in eternity. EXERCISEThe memory of death in its broadest cosmological form (not my own death — but the transience of everything).
2. οἶά ἐστι τὰ αἰσθητὰ πάντα — "what kind of thing all sense-objects are." This is EXERCISEphysical definition applied to a category: look at sensory objects as they are, and especially at those that play upon the three principal false motives — TERMpleasure, pain, vainglory.
3. τί εἰσιν οὗτοι, ὧν αἱ ὑπολήψεις … — "what are these people, whose TERMopinions and voices create reputation?" An analysis of the source of the craving for fame: my εὐδοξία depends on the ὑπολήψεις of others, who in turn are people who do not distinguish good.
4. τί ἐστι τὸ ἀποθανεῖν — "what is dying?" The longest prompt: take death apart by EXERCISEμερισμός τῆς ἐννοίας (the division of the concept), shake off everything that has been imagined around it (TERMτὰ ἐμφανταζόμενα), and see it as TERMthe work of nature. To fear the work of nature is childishness.
5. πῶς ἅπτεται θεοῦ ἄνθρωπος — "how does a human being touch god?" The closing prompt about the divine portion in the human being: through what part of himself (TERMthe ruling part), and in what disposition.

The principal concept — TERMὑπόληψις. This is the first appearance of the term in Book II, and at once in two functions — as the source of false strivings (whose opinions create reputation?) and as the instrument of correct seeing (you will see, and cease to suppose otherwise). Marcus is preparing the ground here for the famous formula of 02-15: «πάντα ὑπόληψις» — "all is judgment." This is not relativism but the definition of the locus of work: with the world directly I can do nothing, but with my own judgments about the world — I can do everything. Epictetus' analogue (Ench. 5): "people are disturbed not by things, but by their δόγματα about things." For details see the card TERMhypolepsis.

Anatomy of the three false motives. Marcus lists the trio: τὰ ἡδονῇ δελεάζοντα ἢ τῷ πόνῳ φοβοῦντα ἢ τῷ τύφῳ διαβεβοημένα — "things that lure with pleasure, frighten with pain, or are puffed up by vainglory." This is the classical Stoic diagnostic: every wrong action runs along one of these three vectors. Pleasure (ἡδονή) and pain (πόνος) are the axes of the present; vainglory (τῦφος) is the axis of the social. Note: τῦφος literally means "smoke, vapour" — the image of an opacity in which the person fails to see reality; the Stoics love this word as a name for empty puffed-up self-magnification. All three motives are dissolved by one and the same therapy: apply the νοερὰ δύναμις (intellectual faculty), see things as they are.

Definitio as a universal method. This is the centre of the passage: the exercise EXERCISEμερισμός τῆς ἐννοίας ("division of the concept") is applied here twice — to sense-objects in general (point 2) and to death in particular (point 4). The method is the same: take the object of a passion, break it down into its material components, and cast off the impressions layered "around it" (τὰ ἐμφανταζόμενα). After the operation the passion loses its support, because its object no longer shines — it has been stripped to its physics. See Med. 6.13 — the most famous applications: Falernian wine, purple, sexual intercourse; each time the everyday-valued is reduced to its material base.

Death as the work of nature. The closing turn of the fourth prompt is elegant: death is not only φύσεως ἔργον (a work of nature), but συμφέρον αὐτῇ (a benefit to nature). This is no empty consolation, but a concrete Stoic thesis: the cosmos is reproduced through a cycle of transformations (see metabole), and individual death is a necessary link in the reproduction of the whole. The same move appears in 02-03: "the cosmos is preserved both by the changes of the elements and by the changes of compound bodies." In 02-12 it is compressed into a single formula.

Finale — the contact with god. The closing question: "how and through what part of himself does a human being touch god?" The Stoic answer is unspoken but implied: through the νοῦς / TERMruling part, which is the divine portion / effluence from the one cosmic Logos. The question is symmetrical with the first prompt about the universal transience: after Marcus has pointed to the finitude of all that is temporal (1) and to the work of nature in death (4), he points to what is not finite — to the rational part through which a human being participates in the divine.

A textual subtlety. The Greek closing «ὅταν πῶς ἔχῃ διακέηται τὸ τοῦ ἀνθρώπου τοῦτο μόριον» — "when this part of the human being is in what disposition" — allows two readings. (a) Long and most translators: "when this part is so disposed" (a cognitive disposition: on the state of the rational part). (b) Rogovin: "what happens with this part upon its separation" (post-mortem: on the fate of the soul after death). The difference turns on how one reads the verb διακείμενος — general "disposed-ness" or specific "separated-ness." The Greek allows both. Long and most modern translators (Hays, Hammond, Hard) choose (a): the passage then closes on the state of the living soul. Rogovin chooses (b): the passage then turns to the after-life. Contextually (a) is more consonant with the preceding clause about φύσεως ἔργον — the talk is of a living link with god, not the post-mortem. But Rogovin's reading is poetic, and it is preserved in the translation.

The disciplines. The principal one is assent: the whole quintet of prompts works on ὑπόληψις / φαντασία — correct perception. The secondary is desire: the false motives (pleasure / pain / vainglory) are motives of the desire-sphere. The discipline of action is not in the background of this passage at all; it is wholly about the seeing of the world.
