To those who fall off from their purpose
Consider as to the things which you proposed to yourself at first, which you have secured and which you have not; and how you are pleased when you recall to memory the one and are pained about the other; and if it is possible, recover the things wherein you failed. For we must not shrink when we are engaged in the greatest combat, but we must even take blows. For the combat before us is not in wrestling and the Pancration, in which both the successful and the unsuccessful may have the greatest merit, or may have little, and in truth may be very fortunate or very unfortunate; but the combat is for good fortune and happiness themselves. Well then, even if we have renounced the contest in this matter, no man hinders us from renewing the combat again, and we are not compelled to wait for another four years that the games at Olympia may come again; but as soon as you have recovered and restored yourself, and employ the same zeal, you may renew the combat again; and if again you renounce it, you may again renew it; and if you once gain the victory, you are like him who has never renounced the combat. Only do not, through a habit of doing the same thing, begin to do it with pleasure, and then like a bad athlete go about after being conquered in all the circuit of the games like quails who have run away.

"The sight of a beautiful young girl overpowers me. Well, have I not been overpowered before? An inclination arises in me to find fault with a person; for have I not found fault with him before?" You speak to us as if you had come off free from harm, just as if a man should say to his physician who forbids him to bathe, "Have I not bathed before?" If, then, the physician can say to him, "Well, and what, then, happened to you after the bath? Had you not a fever, had you not a headache?" And when you found fault with a person lately, did you not do the act of a malignant person, of a trifling babbler; did you not cherish this habit in you by adding to it the corresponding acts? And when you were overpowered by the young girl, did you come off unharmed? Why, then, do you talk of what you did before? You ought, I think, remembering what you did, as slaves remember the blows which they have received, to abstain from the same faults. But the one case is not like the other; for in the case of slaves the pain causes the remembrance: but in the case of your faults, what is the pain, what is the punishment; for when have you been accustomed to fly from evil acts? Sufferings, then, of the trying character are useful to us, whether we choose or not.
