text: For although the body needs many things in order to be strong, yet the mind grows from within, giving to itself nourishment and exercise. Yonder athletes must have copious food, copious drink, copious quantities of oil, and long training besides; but you can acquire virtue without equipment and without expense. All that goes to make you a good man lies within yourself. And what do you need in order to become good? To wish it. But what better thing could you wish for than to break away from this slavery, – a slavery that oppresses us all, a slavery which even chattels of the lowest estate, born amid such degradation, strive in every possible way to strip off? In exchange for freedom they pay out the savings which they have scraped together by cheating their own bellies; shall you not be eager to attain liberty at any price, seeing that you claim it as your birthright? Why cast glances toward your strong-box? Liberty cannot be bought. It is therefore useless to enter in your ledger the item of "Freedom," for freedom is possessed neither by those who have bought it, nor by those who have sold it. You must give this good to yourself, and seek it from yourself.
