Book 6
1.11
And he held virtue to be sufficient in itself to ensure happiness, since it needed nothing else except the strength of a Socrates. And he maintained that virtue is an affair of deeds and does not need a store of words or learning; that the wise man is selfsufficing, for all the goods of others are his; that ill repute is a good thing and much the same as pain; that the wise man will be guided in his public acts not by the established laws but by the law of virtue; that he will also marry in order to have children from union with the handsomest women; furthermore that he will not disdain to love, for only the wise man knows who are worthy to be loved.
1.12
Diocles records the following sayings of his: To the wise man nothing is foreign or impracticable. A good man deserves to be loved. Men of worth are friends. Make allies of men who are at once brave and just. Virtue is a weapon that cannot be taken away. It is better to be with a handful of good men fighting against all the bad, than with hosts of bad men against a handful of good men. Pay attention to your enemies, for they are the first to discover your mistakes. Esteem an honest man above a kinsman. Virtue is the same for women as for men. Good actions are fair and evil actions foul. Count all wickedness foreign and alien.
