There has never been a poet or orator who thought another better than himself.

Philosophy is the true mother of science.

It is not a virtue, but a deceptive copy and imitation of virtue, when we are led to the performance of duty by pleasure as its recompense.

It is difficult to persuade mankind that the love of virtue is the love of themselves.

All the arts, which have a tendency to raise man in the scale of being, have a certain common band of union, and are connected, if I may be allowed to say so, by blood-relationship with one another.

All action is of the mind and the mirror of the mind is the face, its index the eyes.

It is not enough merely possess virtue, as if it were an art; it should be practiced.
