Proper correction will come from one "actuated by good will, devoting himself intelligently and diligently to philosophy, steadfast in principle, careless
of what people think of him, immune from any tendency to demagoguery, free from spitefulness, saying only what fits the occasion,
and not likely to be carried away so as to revile, jeer, belittle, injure
feelings, or resort to tricks of wanton acquiescence or flattery (Ib,
2-13)." The opposite will be expected of one "with an unbridled
tongue, prone to blame others, light-minded so as to be incensed at
slight affronts, bickersome, truculent, or bitter (IIb, 1-7)."
