Book 4.19

No sane man fears the gods; for it is madness to fear what is beneficial, and no man loves those whom he fears. You, Epicurus, ended by making God unarmed; you stripped him of all weapons, of all power, and, lest anyone should fear him, you banished him out of the world. There is no reason why you should fear this being, cut off as he is, and separated from the sight and touch of mortals by a vast and impassable wall; he has no power either of rewarding or of injuring us; he dwells alone half-way between our heaven and that of another world, without the society either of animals, of men, or of matter, avoiding the crash of worlds as they fall in ruins above and around him, but neither hearing our prayers nor interested in us. Yet you wish to seem to worship this being just as a father, with a mind, I suppose, full of gratitude; or, if you do not wish to seem grateful, why should you worship him, since you have received no benefit from him, but have been put together entirely at random and by chance by those atoms and mites of yours? "I worship him," you answer, "because of his glorious majesty and his unique nature." Granting that you do this, you clearly do it without the attraction of any reward, or any hope; there is therefore something which is desirable for itself, whose own worth attracts you, that is, honour. Now what is more honourable than gratitude? the means of practising this virtue are as extensive as life itself.
