Genre and place in the book. An extended treatment of the question "what is worth valuing (τίμιον)?" by elimination: the supposed values are run through and discarded until one true value remains. The principal discipline is desire (the right estimate of what deserves pursuit); the sustaining one is assent (reverence for one's own mind). Kin to 06-14 (the hierarchy of value).
Cutting away the false values. Not valuable is what a human shares with the lower grades of life: breathing (as in plants and animals), TERMthe receiving of impressions, and movement by TERMimpulse — "MOTIFtwitched like a marionette on strings" (νευροσπαστεῖσθαι) — herding, feeding (this last "no better than voiding the residue of food"). Nor is fame valuable: applause is only a "clapping of tongues" (κρότος γλωσσῶν), the acclaim of the crowd. Let the "scrap of glory" (δοξάριον, dismissive) go too.
What remains valuable. The one valuable thing is "to move and to hold oneself still according to one's own constitution (κατὰ τὴν ἰδίαν κατασκευήν)" — the end toward which all arts and cares lead. An argument from function: as every art fits its product to its work (the vine-dresser the vine, the horse-breaker the horse, the trainer the dog), and education the human being, so the good of a human being lies in performing its own function, the activity of the rational nature.
The cost of false valuations. If you value much else, "you will be neither free (ἐλεύθερος), nor self-sufficient (αὐτάρκης), nor TERMfree of passion": envy, jealousy, suspicion, plots against those who hold the desired thing, turmoil, and reproach of the gods necessarily follow. Here the doctrine of the DOGMAsufficiency of virtue is given by contraries: to fasten the good onto the external destroys freedom, self-sufficiency, and ἀπάθεια alike.
Reverence for one's own mind. The resolution: "TERMreverence (αἰδώς) and honour (τιμή) for one's own mind (διάνοια)" makes you pleasing to yourself, attuned to your kind (κοινωνοῖς), and in accord with the gods — "praising all that they assign and ordain" (the acceptance of providence). To value one's own mind = DOGMAto identify oneself with the ruling part; from this come at once inner freedom, social harmony, and agreement with the Whole.
Disciplines and parallels. The principal one is desire (what to value); the secondary is assent (reverence for one's own mind). Parallels: 06-14 (the hierarchy of value — its summit in the rational-social soul); 06-08 (the ruling part determines itself); 05-16 (the good of a rational being is fellowship); the MOTIFmarionette image — Med. 2.2; 3.16; 7.3; 12.19. The doctrines — DOGMAthe sufficiency of virtue, DOGMAthe self as the ruling part.
