Opinion, judgement and what disturbs us
Passages from the Meditations on this theme.
A central Stoic idea is that it is not events but our judgements about them that disturb us. These passages repeat it: take away the opinion, and the harm goes with it.
Remember that all is opinion. For what was said by the Cynic Monimus is manifest: and manifest too is the use of what was said, if a man receives what may be got out of it as far as it is true.
Reverence the faculty which produces opinion. On this faculty it entirely depends whether there shall exist in thy ruling part any opinion inconsistent with nature and the constitution of the rational animal. And this faculty promises freedom from hasty judgment, and friendship towards men, and obedience to the gods.
Take away thy opinion, and then there is taken away the complaint, "I have been harmed." Take away the complaint, "I have been harmed," and the harm is taken away.
Do not have such an opinion of things as he has who does thee wrong, or such as he wishes thee to have, but look at them as they are in truth.
A man should always have these two rules in readiness; the one to do only whatever the reason of the ruling and legislating faculty may suggest for the use of men; the other, to change thy opinion, if there is any one at hand who sets thee right and moves thee from any opinion. But this change of opinion must proceed only from a certain persuasion, as of what is just or of common advantage, and the like, not because it appears pleasant or brings reputation.
Things themselves touch not the soul, not in the least degree; nor have they admission to the soul, nor can they turn or move the soul: but the soul turns and moves itself alone, and whatever judgments it may think proper to make, such it makes for itself the things which present themselves to it.
The text is George Long's English translation of 1862, in the public domain, and its old-fashioned English ("thou", "thy") is unchanged. The notes beside it are our own wording. Marcus Aurelius wrote these for himself; they are a diary, not a book of rules.
