Retire into thyself. The rational principle which rules has this nature, that it is content with itself when it does what is just, and so secures tranquility.

We must press on then, in haste; not simply because every hour brings us nearer to death, but because even before then our powers of perception and comprehension begin to deteriorate.

That which makes the man no worse than he was makes his life no worse: it has no power to harm, without or within.

The true worth of a man is to be measured by the objects he pursues.

The noblest kind of retribution is not to become like your enemy.

You exist but as a part inherent in a greater whole. Do not live as though you had a thousand years before you. The common due impends; while you live, and while you may, be good.

In the end, what would you gain from everlasting remembrance? Absolutely nothing. So what is left worth living for? This alone: justice in thought, goodness in action, speech that cannot deceive, and a disposition glad of whatever comes, welcoming it as necessary, as familiar, as flowing from the same source and fountain as yourself.
