There is a foolish corner in the brain of the wisest man.

Plato is dear to me, but dearer still is truth.

Those who are not angry at the things they should be angry at are thought to be fools, and so are those who are not angry in the right way, at the right time, or with the right persons.

We praise a man who feels angry on the right grounds and against the right persons and also in the right manner at the right moment and for the right length of time.

The man who is isolated, who is unable to share in the benefits of political association, or has no need to share because he is already self-sufficient, is no part of the polis, and must therefore be either a beast or a god.

If it is better to be happy as a result of one's own exertions than by the gift of fortune, it is reasonable to suppose that this is how happiness is won.

Criticism is something we can avoid easily by saying nothing, doing nothing, and being nothing.

Happiness is the exercise of talent, along the lines of excellence.

It is just that we should be grateful, not only to those with whose views we may agree, but also to those who have expressed more superficial views; for these also contributed something, by developing before us the powers of thought.

Some kinds of animals burrow in the ground; others do not. Some animals are nocturnal, as the owl and the bat; others use the hours of daylight. There are tame animals and wild animals. Man and the mule are always tame; the leopard and the wolf are invariably wild, and others, as the elephant, are easily tamed.

Thus we must advance from generalities to particulars; for it is a whole that is best known to sense-perception, (25) and a generality is a kind of whole, comprehending many things within it, like parts.

It is during our darkest moments that we must focus to see the light.

Courage is a mean with regard to fear and confidence.

The more you know, the more you know you don't know.
