A person is an individual substance of a rational nature.

Balance out the good things and the bad that have happened in your life and you will have to acknowledge that you are still way ahead. You are unhappy because you have lost those things in which you took pleasure? But you can also take comfort in the likelihood that what is now making you miserable will also pass away.

So nothing is ever good or bad unless you think it so, and vice versa. All luck is good luck to the man who bears it with equanimity.

Good men seek it by the natural means of the virtues; evil men, however, try to achieve the same goal by a variety of concupiscences, and that is surely an unnatural way of seeking the good. Don't you agree?

Nothing is miserable unless you think it so.

Wretched men cringe before tyrants who have no power, the victims of their trivial hopes and fears. They do not realise that anger is hopeless, fear is pointless and desire all a delusion. He whose heart is fickle is not his own master, has thrown away his shield, deserted his post, and he forges the links of the chain that holds him.

If there is a God, whence proceed so many evils? If there is no God, whence cometh any good?
