Good breeding in cattle depends on physical health, but in men on a well-formed character.

Durant (1939), Ch. XVI, §II, p. 354; citing C. Bakewell, Sourcebook in Ancient Philosophy, New York, 1909, "Fragment 57"

Strength of body is nobility only in beasts of burden, strength of character is nobility in man. || In cattle excellence is displayed in strength of body; but in men it lies in strength of character.
