Consider this quote by Marcus Aurelius:
Art thou angry with him whose armpits
stink ? art thou angry with him whose mouth
smells foul ? What good will this anger do
thee ? He has such a mouth, he has such arm-
pits: it is necessary that such an emanation
must come from such things: but the man has
reason, it will be said, and he is able, if he
takes pains, to discover wherein he offends; I
wish thee well of thy discovery. Well then,
and thou hast reason: by thy rational faculty
stir up his rational faculty; show him his error,
admonish him. For if he listens, thou wilt
cure him, and there is no need of anger.
It confuses me. I have a commented, curated version of Meditations in which this is not included. But the sentiment in that version is that "take away then, when you choose, your opinion, and like a mariner, who has doubled the promontory, you shall find calm, everything stable, and a waveless bay." You can always take away you opinion and everything is opinion. Why, all of a sudden, is the perception of this smell not an opinion that can be taken away, and if that opinion can easily be taken away, why then admonish someone for something that it completely natural? Would it not be easier to choose one's set of opinions such that they agree with all things natural to this world?
