Of the sources of pleasure, some are necessary, and others are desirable in themselves but admit of excess: “necessary” are the bodily processes, such as nutrition, the propagation of the species, and generally those bodily functions with which we said that profligacy and temperance have to do; others, though not necessary, are in themselves desirable, such as victory, honour, wealth, and other things of the kind that are good and pleasant. 187
Now, those who go to excess in these latter in spite of their own better reason are not called incontinent simply, but with a qualifying epithet, as incontinent with respect to money, or gain, or honour, or anger—not simply, since they are different characters, and only called incontinent in virtue of a resemblance—just as the victor in the last Olympic games was called a man; for though the meaning of the name as applied to him was but slightly different from its common meaning, still it was different. 188
