The Stoics say, "Retire within yourselves; it is there you will find your rest." And that is not true. Others say, "Go out of yourselves; seek happiness in amusement." And this is not true. Illness comes. Happiness is neither without us nor within us. It is in God, both without us and within us.

Desire and force between them are responsible for all our actions; desire causes our voluntary acts, force our involuntary.
