One line on the boundary of power. A miniature aphorism, the direct sequel to 8.3: the conqueror is "slave" to many because he strains to govern the ungovernable. Here is the DOGMAdichotomy of control at its most compressed: the conduct of others (τὰ αὐτὰ ποιήσουσι — "they will do the same things") is not in your power, and your indignation will not alter it. The verb διαρραγῇς — "though you should burst" (literally "be torn apart"): anger at others' acts only ruptures you, leaving them untouched. Cf. Med. 8.56 (another's ruling mind is nothing to me), 9.42 (do not marvel that the shameless man is shameless). Rogovin's «как ты ни бейся» renders κἂν σὺ διαρραγῇς exactly. The governing discipline is desire (not to will the impossible — to remake others), the sustaining one assent (not to pass the judgment "this is unbearable").
