Let us be well persuaded that everyone of us possesses happiness in proportion to his virtue and wisdom, and according as he acts in obedience to their suggestion.
Happiness does not consist in amusement. In fact, it would be strange if our end were amusement, and if we were to labor and suffer hardships all our life long merely to amuse ourselves.... The happy life is regarded as a life in conformity with virtue. It is a life which involves effort and is not spent in amusement.
One kind of justice is that which is manifested in distributions of honour or money or the other things that fall to be divided among those who have a share in the constitution ... and another kind is that which plays a rectifying part in transactions.
