and to the other precepts which follow. Consider now the fiery and bitter horn of fornication, by which he casts down the incontinent; consider adultery, consider falsehood, covetousness, theft, and the other sister and related vices, which flourish by nature around his murderous heads, which if you root out with the aid of Christ, you will receive, as it were, divine heads, and will bloom with the crowns gained from the dragon. For it is our duty to prefer and to set forward the best things, who have received, above the earth-born, a commanding and voluntary mind, and one free from all necessity, so as to make choice like masters of the things which please us, not being in bondage to fate or fortune. And so no man would be master of himself and good, unless selecting the human example of Christ, and bringing himself to the likeness of Him, he should imitate Him in his manner of life. For of all evils the greatest which is implanted in many is that which refers the causes of sins to the motions of the stars, and says that our life is guided by the necessities of fate, as those say who study the stars, with much insolence. For they, trusting more in guessing than in prudence, that is, in something between truth and falsehood, go far astray from the sight of things as they are. Whence, if you permit me, O Arete, now that I have completed the discourse which you, my mistress, appointed to be spoken, I will endeavour, with your assistance and favour, to examine carefully the position of those who are offended, and deny that we speak the truth, when we say that man is possessed of free-will, and prove that
"They perish self-destroyed,
By their own fault," 
choosing the pleasant in preference to the expedient.
Arete. I do permit you and assist you; for your discourse will be perfectly adorned when you have added this to it.
