text: Why do you bore me with that which you yourself call the "liar" fallacy, about which so many books have been written? Come now, suppose that my whole life is a lie; prove that to be wrong and, if you are sharp enough, bring that back to the truth. At present it holds things to be essential of which the greater part is superfluous. And even that which is not superfluous is of no significance in respect to its power of making one fortunate and blest. For if a thing be necessary, it does not follow that it is a good. Else we degrade the meaning of "good," if we apply that name to bread and barley-porridge and other commodities without which we cannot live. The good must in every case be necessary; but that which is necessary is not in every case a good, since certain very paltry things are indeed necessary. No one is to such an extent ignorant of the noble meaning of the word "good," as to debase it to the level of these humdrum utilities.
