I am never less alone than when alone.

The precept, 'Know thyself,' was not solely intended to obviate the pride of mankind; but likewise that we might understand our own worth.

We should measure affection, not like youngsters by the ardor of its passion, but by its strength and constancy.

The authority of those who teach is often an obstacle to those who want to learn.

Only those who are able to relax can create, and then ideas reach the mind like lightning.

A thankful heart is not only the greatest virtue but the parent of all virtues.

Any man can make mistakes, but only an idiot persists in his error.

He who acknowledges a kindness has it still, and he who has a grateful sense of it has requited it.

Gratitude is not only the greatest of virtues, but the parent of all others.

In men of the highest character and noblest genius there is to be found an insatiable desire for honor, command, power, and glory.
