Aurelius, Meditations §aur_06_xl: Whatsoever in any kind doth happen to any one, is expedient to the whole.

Whatsoever in any kind doth happen to any one, is expedient to the whole. And thus much to content us might suffice, that it is expedient for the whole in general. But yet this also shalt thou generally perceive, if thou dost diligently take heed, that whatsoever doth happen to any one man or men.... And now I am content that the word expedient, should more generally be understood of those things which we otherwise call middle things, or things indifferent; as health, wealth, and the like.
