Providence or atoms — again. The same disjunction as at 9.28: either all is "from one intelligent source" (μία πηγὴ νοερά) and coheres DOGMA"as in one body" (ὡς ἑνὶ σώματι) — and then DOGMAit does not befit the part to blame what is done for the sake of the Whole; or DOGMAatoms, "a jumble and a scattering" (κυκεὼν καὶ σκεδασμός). Under either outcome the disturbance is groundless.
A shout to the ruling part. The close is a set of sharp questions to the TERMἡγεμονικόν: "are you dead? corrupted? turned beast? playing a part? grazing in the herd?" If the ruling part is alive and rational, it has nothing to be disturbed by; if it has given way, the questions strike at its torpor and rouse it to its own nature. The governing discipline is desire (to accept the order of the Whole), the sustaining one assent.
Textual note. The editions print τῷ ἡγεμονικῷ λέγειν — an imperatival infinitive ("say to the ruling part"); both Long ("Say to the ruling faculty") and Rogovin ("Скажи руководящему началу") follow it. The indicative λέγεις ("you say"), found in part of the tradition, severs the sentence from both translations; λέγειν is printed here.
