Diseases of the soul are more dangerous and more numerous than those of the body.

Read at every wait; read at all hours; read within leisure; read in times of labor; read as one goes in; read as one goest out. The task of the educated mind is simply put: read to lead.

The real friend is another self.

Every animal loves itself.

Justice consists in doing no injury to men; decency in giving them no offense.

Friendship embraces innumerable ends; turn where you will it is ever at your side; no barrier shuts it out; it is never untimely and never in the way.

The master sometimes serves, and the servant sometimes is master.
