Letters 66.48

We therefore find mentioned, even by Epicurus, those goods which one would prefer not to experience; which, however, because circumstances have decided thus, must be welcomed and approved and placed on a level with the highest goods. We cannot say that the good which has rounded out a happy life, the good for which Epicurus rendered thanks in the last words he uttered, is not equal to the greatest.
