"What then, Marcia, is it that grieves you? is it that your son has died, or that he did not live long? If it be his having died, then you ought always to have grieved, for you always knew that he would die. Reflect that the dead suffer no evils, that all those stories which make us dread the nether world are mere fables, that he who dies need fear no darkness, no prison, no blazing streams of fire, no river of Lethe, no judgment seat before which he must appear, and that Death is such utter freedom that he need fear no more despots. All that is a phantasy of the poets, who have terrified us without a cause. Death is a release from and an end of all pains: beyond it our sufferings cannot extend: it restores us to the peaceful rest in which we lay before we were born. If anyone pities the dead, he ought also to pity those who have not been born. Death is neither a good nor a bad thing, for that alone which is something can be a good or a bad thing: but that which is nothing, and reduces all things to nothing, does not hand us over to either fortune, because good and bad require some material to work upon. Fortune cannot take hold of that which Nature has let go, nor can a man be unhappy if he is nothing. Your son has passed beyond the border of the country where men are forced to labour; he has reached deep and everlasting peace. He feels no fear of want, no anxiety about his riches, no stings of lust that tears the heart in guise of pleasure: he knows no envy of another's prosperity, he is not crashed by the weight of his own; even his chaste ears are not wounded by any ribaldry: he is menaced by no disaster, either to his country or to himself. He does not hang, full of anxiety, upon the issue of events, to reap even greater uncertainty as his reward: he has at last taken up a position from which nothing can dislodge him, where nothing can make him afraid."
