Marcus Aurelius
Meditations 12.5
How can it be that the gods, after having arranged all things well and benevolently for mankind, have overlooked this alone, that some men, and very good men, and men who, as we may say, have had most communion with the divinity, and through pious acts and religious observances have been most intimate with the divinity, when they have once died should never exist again, but should be completely extinguished?
But if this is so, be assured that if it ought to have been otherwise, the gods would have done it. For if it were just, it would also be possible; and if it were according to nature, nature would have had it so. But because it is not so, if in fact it is not so, be thou convinced that it ought not to have been so: for thou seest even of thyself that in this inquiry thou art disputing with the Deity; and we should not thus dispute with the gods, unless they were most excellent and most just; but if this is so, they would not have allowed anything in the ordering of the universe to be neglected unjustly and irrationally.
Marcus Aurelius, Meditations 12.5, translated by George Long
How can the Gods, after disposing all things well and with good will towards men, ever have overlooked this one thing, that some of mankind, and they especially good men, who have had as it were the closest commerce with the Divine, and by devout conduct and acts of worship have been in the most intimate fellowship with it, should when once dead have no second existence but be wholly extinguished? But if indeed this be haply so, doubt not that they would have ordained it otherwise, had it needed to be otherwise. For had it been just, it would also have been feasible, and had it been in conformity with Nature, Nature would have brought it about. Therefore from its not being so, if indeed it is not so, be assured that it ought not to have been so. For even thyself canst see that in this presumptuous enquiry of thine thou art reasoning with God. But we should not thus be arguing with the Gods were they not infinitely good and just. But in that case they could not have overlooked anything being wrongly and irrationally neglected in their thorough Ordering of the Universe.
