Wisdom is knowing when you don't know

In all of us, even in good men, there is a lawless wild-beast nature, which peers out in sleep.

We are what we think we are

YOU ARE NOT ONLY GOOD TO YOURSELF, BUT THE CAUSE OF GOODNESS IN OTHERS

Pride divides the men, humility joins them.

I will not yield to any man contrary to what is right, for fear of death, even if I should die at once for not yielding.

Antiphon, as another man gets pleasure from a good horse, or a dog, or a bird, I get even more pleasure from good friends. And if I have something good, I teach it to them, and I introduce them to others who will be useful to them with respect to virtue. And together with my friends I go through the treasures of wise men of old which they left behind written in books, and we peruse them. If we see something good, we pick it out and hold it to be a great profit, if we are able to prove useful to one another.
