Strip the judge bare. Again the dissection of the one who appraises (cf. 9.18, 9.27): what are their TERMruling principles, on what are they intent, for what do they love and honour?

"What conceit." The coda — DOGMAὅση οἴησις: "what self-delusion" in their supposing that they "harm by blame or help by praise." Neither: the praise and blame of such people do not touch your good (which lies in your own action, not in their opinion). The governing discipline is assent.
