Gratitude is a virtue disposing the mind to an inward sense and an outward acknowledgment of a benefit received, together with a readiness to return the same, or the like, as occasions of the doer of it shall require, and the abilities of the receiver extend to. He who receives a good turn, should never forget it: he who does one, should never remember it.

He that boasts of his ancestors confesses that he has no virtue of his own. No person ever lived for our honor; nor ought that to be reputed ours, which was long before we had a being; for what advantage can it be to a blind man to know that his parents had good eyes? Does he see one whit the better?

The true science and study of mankind is man.
