George Eliot: Legend of Jubal.
Nor must we childishly feel contempt for the study of the lower animals, since in all nature's work there is something wonderful. And if any one thinks the study of other animals despicable, he must despise the study of his own nature.
Aristotle.
VIRTUE.
Thus born alike, from virtue first began
The diff'rence that distinguished man from man:
He claimed no title from descent of blood;
But that which made him noble made him good.
Dryden.
