Marcus Aurelius and his attitude toward various kerfluffles. From the Meditations Book Nine.

 "Today I have got out of all trouble, or rather I have cast off all trouble, for it was not outside, but within and in my opinions."

*He is bound to accept the universe or suffer through a contrarian opinion within himself.  He believed in a guiding principle to the universe, and could to some extent trust that.

"All things are the same, familiar in experience, and ephemeral in time, and worthless in the matter.  Everything now is just as it was in the time of those whom we have buried."

"The stone which has been thrown up it is no evil to come down, nor indeed any good to have been carried up.

Penetrate towards into men's leading principles, and thou wilt see what judges thou art afraid of, and what kind of judges they are of themselves.

All things are changing: and thou thyself art in continuous mutation and in a manner in continuous destruction, and the whole universe, too."

*We need not, according to the good emperor, know not fear or anger at bad acts or judgements, but put them perspective and attempt to focus our attention within, focus our jealousies and guiles, not on things without, but things within.

"Not in passivity but in activity lie the evil and the good of the rational social animal, just as his virtue and his vice lie not in passivity, but in activity.

It is thy duty to leave another man's wrongful act there where it is."

*We see so often and are told of "sins of omission" or "sins of inaction" in which so much of the world's evil comes forward and must be stopped, but here Aurelius threads the needle, notwithstanding his own military campaigns and incursions.
