Suppose, what is quite possible, that there is one so frugal and sparing in his diet, that, instead of gratifying his appetite or his palate, he refrains from eating twice in one day, and at supper takes a little cabbage moistened and seasoned with lard, just enough to keep down hunger; and quenches his thirst, from regard to his health, with two or three draughts of pure wine; and this is his regular diet: whereas another of different habits never takes flesh or wine, but makes an agreeable repast at two o’clock on rare and foreign vegetables, varied with a number of courses, and well sprinkled with pepper, and sups in the same style towards night; and drinks honey-vinegar, mead, raisin-wine, and the juices of various fruits, no bad imitation of wine, and even surpassing it in sweetness; and drinks not for thirst but for pleasure; and makes this provision for himself daily, and feasts in this sumptuous style, not because he requires it, but only gratifying his taste;—which of these two do you regard as living most abstemiously in food and drink? You cannot surely be so blind as not to put the man of the little lard and wine above this glutton!
