Meditations 6.23

As to the animals which have no reason, and generally all things and objects, do thou, since thou hast reason and they have none, make use of them with a generous and liberal spirit. But towards human beings, as they have reason, behave in a social spirit. And on all occasions call on the gods, and do not perplex thyself about the length of time in which thou shalt do this; for even three hours so spent are sufficient.

Marcus Aurelius, Meditations 6.23, translated by George Long

Conduct thyself with magnanimity and freedom towards irrational creatures and, generally, towards circumstances and objective things, for thou hast reason and they have none. But men have reason, therefore treat them as fellow creatures. And in all cases call upon the Gods, and do not concern thyself with the question, How long shall I do this? Three hours are enough so spent.

Marcus Aurelius, Meditations 6.23, translated by C. R. Haines
