"Humane nature I always thought the most useful object of humane reason, and to make the consideration of it pleasant and entertaining, I always thought the best employment of humane wit: other parts of philosophy may perhaps make us wiser, but this not only answers to that end, but makes us better too. Hence it was that the Oracle pronounced Socrates the wisest of all men living, because he judiciously made choice of human nature for the object of his thoughts; an enquiry into which as much exceeds all other learning, as it is of more consequence to adjust the true nature and measures of right and wrong, than to settle the distance of the planets, and compute the times of their circumvolutions."
