Unremarkable lives are marked by the fear of not looking capable when trying something new.

It is a mark of a mean capacity to spend much time on the things which concern the body, such as much exercise, much eating, much drinking, much easing of the body, much copulation. But these things should be done as subordinate things: and let all your care be directed to the mind.

Truth is a thing immortal and perpetual, and it gives to us a beauty that fades not away in time, nor does it take away the freedom of speech which proceeds from justice; but it gives to us the knowledge of what is just and lawful, separating from them the unjust and refuting them.

The two powers which in my opinion constitute a wise man are those of bearing and forbearing.

Never depend on the admiration of others for self-satisfaction. It is a fact of life that other people, even people who love you, will not necessarily agree with your ideas, understand you always, or share your enthusiasms.

It doesn't take much to lose everything, just a little departure from reason

Some things are up to us [eph' hêmin] and some things are not up to us. Our opinions are up to us, and our impulses, desires, aversions–in short, whatever is our own doing. Our bodies are not up to us, nor are our possessions, our reputations, or our public offices, or, that is, whatever is not our own doing.
