Oh, certainly (says some one); but we have assigned each form to its proper place by this time; and if you disregard that—even though there was no bad meaning in what you did say—you cannot fairly claim to have made no mistake; it is as though one should put a helmet on the shins, or greaves on the head. My dear sir (I reply), your simile would go on all fours if there were any season at all which did not require health; but in point of fact it is needed in the morning and at noonday and at night—especially by busy rulers like you Romans, to whom physical condition is so important. And again, the man who gives you Joy is only beginning auspiciously; it is no more than a prayer; whereas he who bids you Hail is doing you a practical service in reminding you of the means to health; his is more than a prayer, it is a precept.
