Vivere est cogitare. (To think is to live)

No tempest or conflagration, however great, is harder to quell than mob carried away by the novelty of power.

The purpose of education is to free the student from the tyranny of the present.

No wise man has called a change of opinion in constancy.

For out of such an ungoverned populace one is usually chosen as a leader, someone bold and unscrupulous who curries favor with the people by giving them other men's property. To such a man the protection of public office is given, and continually renewed. He emerges as a tyrant over the very people who raised him to power.

It is better to receive than to do injury.

He removes the greatest ornament of friendship who takes away from it respect.
