Friendship improves happiness and abates misery, by the doubling of our joy and the dividing of our grief.

Let each man have according to his deserts.

Friendship was given by nature to be an assistant to virtue, not a companion in vice.

I know not any season of life that is past more agreeably than virtuous old age.

Let arms give place to the robe, and the laurel of the warriors yield to the tongue of the orator.

It is not enough merely possess virtue, as if it were an art; it should be practiced.

Reason is the mistress and queen of all things.

The last day does not bring extinction to us, but change of place.

To know the laws is not to memorize their letter but to grasp their full force and meaning.

There is not only an art, but an eloquence in it.

Fewer possess virtue, than those who wish us to believe that they possess it.

No man in his senses will dance.

That last day does not bring extinction to us, but change of place.

We make allowance for necessity.

We are all excited by the love of praise, and the noblest are most influenced by glory.

Just what is the civil law? What neither influence can affect, nor power break, nor money corrupt: were it to be suppressed or even merely ignored or inadequately observed, no one would feel safe about anything, whether his own possessions, the inheritance he expects from his father, or the bequests he makes to his children.

I know that it is likely that as worship of the gods declines, faith between men and all human society will disappear, as well as that most excellent of all virtues, which is justice.

Anger should never appear in awarding punishment.

How great an evil do you see that may have been announced by you against the Republic?

Nature has planted in our minds an insatiable longing to see the truth.
