XXIV. These cases are not alike, Cato. For in these instances, though you may have made a good deal of progress, still you are in exactly the same evil from which you wish to be free, till you have entirely escaped. For a man does not breathe till he has entirely emerged, and puppies are just as blind till they have opened their eyes, as if they were never going to open them. I will give you some instances that really are like. One man’s eyes are bad, another is weak in his body; these men are both gradually relieved by the daily application of remedies. The one gets better every day, and the other sees better. Now these men resemble all those who study virtue. They are relieved of their vices; they are relieved of their errors. Unless, perchance, you think that Tiberius Gracchus, the father, was not happier than his son, when the one laboured to establish the republic, and the other to subvert it. And yet he was not a wise man. For who taught him wisdom? or when? or where? or whence did he learn it? Still, because he consulted his twin glory and dignity, he had made great progress in virtue. But I will compare your grandfather, Drusus, with Caius Gracchus, who was nearly his contemporary. He healed the wounds which the other inflicted on the republic. But there is nothing which makes men so miserable as impiety and wickedness. Grant that all those who are unwise are miserable, as, in fact, they are; still he is not equally miserable who consults the interest of his country with him who wishes for its destruction. Therefore, those men are already a great deal relieved from their vices who have made any considerable advance towards virtue. But the men of your school admit that advance towards virtue can be made, but yet assert that no relief from vices takes place in consequence.
