Meditations 1:14

[MY BROTHER] SEVERUS

To love my family, truth and justice. It was through him that I encountered Thrasea, Helvidius, Cato, Dion and Brutus, and conceived of a society of equal laws, governed by equality of status and of speech, and of rulers who respect the liberty of their subjects above all else.

And from him as well, to be steady and consistent in valuing philosophy.

And to help others and be eager to share, not to be a pessimist, and never to doubt your friends' affection for you.

And that when people incurred his disapproval, they always knew it. And that his friends never had to speculate about his attitude to anything: it was always clear.
