Juvenal, 10th Satire, The Vanity of Human Wishes

Is there nothing then for which men shall pray? If you ask my counsel, you will leave it to the gods themselves to provide what is good for us, and what will be serviceable for our state; for, in place of what is pleasing, they will give us what is best. Man is dearer to them than he is to himself. Impelled by strong and blind desire, we ask for wife and offspring; but the gods know ot what sort the sons, of what sort the wife, will be. Nevertheless that you may have something to pray for, and be able to offer to the shrines entrails and presaging sausages from a white porker, you should pray for a sound mind in a sound body; for a stout heart that has no fear of death, and deems length of days the least of Nature's gifts; that can endure any kind of toil; that knows neither wrath nor desire, and thinks that the woes and hard labours of Hercules are better than the loves and the banquets and the down cushions of Sardanapalus. What I commend to you, you can give to yourself; for it is assuredly through virtue that lies the one and only road to a life of peace. Thou wouldst have no divinity, O Fortune, if we had but wisdom; it is we that make a goddess of thee, and place thee in the skies.
