Marcus Tullius Cicero

For no phase of life, whether public or private, whether in business or in the home, whether one is working on what concerns oneself alone or dealing with another, can be without its moral duty; on the discharge of such duties depends all that is morally right, and on their neglect all that is morally wrong in life.

Not to know what happened before you were born is always to remain a child. For what is a man's life if it is not linked with the life of future generations by memories of the past.

Quod est ante pedes nemo spectat: coeli scrutantur plagas.
(No one sees what is before his feet: we all gaze at the stars.)

No sane man will dance.

Times are bad. Children no longer obey their parents, and everyone is writing a book.

All splendid things are rare.

In the very books in which philosophers bid us scorn fame, they inscribe their names.

There is nothing so absurd but some philosopher has said it.

Wise men are instructed by reason; men of less understanding, by experience; the most ignorant, by necessity; the beasts, by nature.

An unjust peace is better than a just war.
