Aristotle, Nicomachean Ethics
H. Rackham, Ed.

The following considerations also will show that perfect happiness is some form of contemplative activity. The gods, as we conceive them, enjoy supreme felicity and happiness. But what sort of actions can we attribute to them? Just actions? but will it not seem ridiculous to think of them as making contracts, restoring deposits and the like? Then brave actions—enduring terrors and running risks for the nobility of so doing? Or liberal actions? but to whom will they give? Besides, it would be absurd to suppose that they actually have a coinage or currency of some sort! And temperate actions—what will these mean in their case? surely it would be derogatory to praise them for not having evil desires! If we go through the list we shall find that all forms of virtuous conduct seem trifling and unworthy of the gods. Yet nevertheless they have always been conceived as, at all events, living, and therefore living actively, for we cannot suppose they are always asleep like Endymion. But for a living being, if we eliminate action, and a fortiori creative action, what remains save contemplation? It follows that the activity of God, which is transcendent in blessedness, is the activity of contemplation; and therefore among human activities that which is most akin to the divine activity of contemplation will be the greatest source of happiness.
