To be always seeking after the useful does not become free and exalted souls.

The soul becomes prudent by sitting and being quiet.

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

Man perfected by society is the best of all animals; he is the most terrible of all when he lives without law and without justice. If he finds himself an individual who cannot live in society, or who pretends he has need of only his own resources do not consider him as a member of humanity; he is a savage beast or a god.

The virtue of the good man is necessarily the same as the virtue of the citizen of the perfect state.

He who cannot see the truth for himself, nor, hearing it from others, store it away in his mind, that man is utterly worthless.

The duty of rhetoric is to deal with such matters as we deliberate upon without arts or systems to guide us, in the hearing of persons who cannot take in at a glance a complicated argument or follow a long chain of reasoning.
