Letters 120.2

This is what I mean: Some believe the Good to be that which is useful; they accordingly bestow this title upon riches, horses, wine, and shoes; so cheaply do they view the Good, and to such base uses do they let it descend. They regard as honourable that which agrees with the principle of right conduct —such as taking dutiful care of an old father, relieving a friend’s poverty, showing bravery on a campaign, and uttering prudent and well-balanced opinions.
