If virtue were its own reward, it would no longer be a human quality, but supernatural.

All grand thoughts come from the heart.

One can not be just if one is not humane.

Few people are modest enough to be estimated at their true worth.

Sometimes a lengthened period of prosperity melts away in a moment; just as the heat of summer flies before a day of tempest.

Whatever affection we have for our friends or relations, the happiness of others never suffices for our own.

If our friends do us a service, we think they owe it to us by their title of friend. We never think that they do not owe us their friendship.
