Marcus Aurelius
Meditations 1.14
From my brother Severus, to love my kin, and to love truth, and to love justice; and through him I learned to know Thrasea, Helvidius, Cato, Dion, Brutus; and from him I received the idea of a polity in which there is the same law for all, a polity administered with regard to equal rights and equal freedom of speech, and the idea of a kingly government which respects most of all the freedom of the governed; I learned from him also consistency and undeviating steadiness in my regard for philosophy; and a disposition to do good, and to give to others readily, and to cherish good hopes, and to believe that I am loved by my friends; and in him I observed no concealment of his opinions with respect to those whom he condemned, and that his friends had no need to conjecture what he wished or did not wish, but it was quite plain.
Marcus Aurelius, Meditations 1.14, translated by George Long
From my 'brother' Severus, love of family, love of truth, love of justice, and (thanks to him!) to know Thrasea, Helvidius, Cato, Dion, Brutus; and the conception of a state with one law for all, based upon individual equality and freedom of speech, and of a sovranty which prizes above all things the liberty of the subject; and furthermore from him also to set a well-balanced and unvarying value on philosophy; and readiness to do others a kindness, and eager generosity, and optimism, and confidence in the love of friends; and perfect openness in the case of those that came in for his censure; and the absence of any need for his friends to surmise what he did or did not wish, so plain was it.
