2.276-277 (tr. Richmond Lattimore):
For few are the children who turn out to be the equals of their fathers, and the greater number are worse; few are better than their father is.
Euripides, Children of Heracles
327-328 (tr. David Kovacs):
Only one man out of a great multitude can be found who is not inferior to his father.
3.6.45-48 (tr. John Conington):
What has not cankering Time made worse?
Viler than grandsires, sires beget
Ourselves, yet baser, soon to curse
The world with offspring baser yet.
damnosa quid non inminuit dies?
aetas parentum, peior avis, tulit
nos nequiores, mox daturos
My children are exceptions to this rule; I am not.
