Cyropaedia

Now Cyaxares seemed to feel some little jealousy because the proposal came from them; at the same time, perhaps, he did not care to risk another engagement; then, too, he rather wished to stay where he was, for it happened that he was busily engaged in making merry himself, and he saw that many of the other Medes were doing the same. However that may be, he spoke as follows:[*](Cyaxares replies)

Well, Cyrus, I know from what I see and hear that you Persians are more careful than other people not to incline to the least intemperance in any kind of pleasure. But it seems to me that it is much better to be moderate in the greatest pleasure than to be moderate in lesser pleasures; and what brings to man greater pleasure than success, such as has now been granted us?

If, therefore when we are successful, we follow up our success with moderation, we might, perhaps, be able to grow old in happiness unalloyed with danger. But if we enjoy it intemperately and try to pursue first one success and then another, see to it that we do not share the same fate that they say many have suffered upon the sea, that is, because of their success they have not been willing to give up seafaring, and so they have been lost; and many others, when they have gained a victory, have aimed at another and so have lost even what they gained by the first.

And that is the way with us; for if it were because they were inferior to us in numbers that the enemy are fleeing from us, perhaps it might be safe for us actually to pursue this lesser army. But, as it is, reflect with what a mere fraction of their numbers we, with all our forces, have fought and won, while the rest of theirs have not tasted of battle; and if we do not compel them to fight, they will remain unacquainted with our strength and with their own, and they will go away because of their ignorance and cowardice. But if they discover that they are in no less danger if they go away than if they remain in the field, beware lest we compel them to be valiant even against their will.
