We can do noble acts without ruling the earth and sea

Friends are an aid to the young, to guard them from error; to the elderly, to attend to their wants and to supplement their failing power of action; to those in the prime of life, to assist them to noble deeds.

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

Some men are just as firmly convinced of what they think as others of what they know

All human happiness or misery takes the form of action; the end for which we live is a certain kind of action.

A tragedy is the imitation of an action that is serious, and also, as having magnitude, complete in itself . . . with incidents arousing pity and terror, with which to accomplish its purgation of these emotions.
