To Prove that every Man who is virtuous is also free (16-20)

Slavery, then, is of two kinds; slavery of the soul and slavery of the body. Now, of our bodies, men are masters; but over our souls, wickedness and the passions have the dominion. And we may speak of freedom in the same manner. For one kind of freedom gives fearlessness of body in respect of any dangers which can come upon it from men of still more powerful body; while the other produces peace to the mind, by putting a check upon the authority of the passions.

Now, about the former kind, scarcely any one ever raises any question; for the chances of fortune which happen to men are infinite in number, and it often happens that men of the highest virtue have fallen into unexpected misfortunes, and so have lost the freedom which belonged to them through their birth. But there is room for inquiry about those manners which neither desires, nor fears, nor pleasures, nor pains, have ever brought under the yoke, as if they had come forth out of confinement, and as if the chains by which they had been bound were now loosened.

For, in real truth, that man alone is free who has God for his leader; indeed, in my opinion, that man is even the ruler of all others, and has all the affairs of the earth committed to him, being, as it were, the viceroy of a great king, the mortal lieutenant of an immortal sovereign. However, this assertion of the actual authority of the wise man may be postponed to a more suitable opportunity. We must at present examine minutely the question of his perfect freedom.
