Context

“He is the son of a miserly oligarch, and has been taught by him to restrain the love of unnecessary pleasures. Perhaps I ought to explain this latter term:—Necessary pleasures are those which are good, and which we cannot do without; unnecessary pleasures are those which do no good, and of which the desire might be eradicated by early training. For example, the pleasures of eating and drinking are necessary and healthy, up to a certain point; beyond that point they are alike hurtful to body and mind, and the excess may be avoided. When in excess, they may be rightly called expensive pleasures, in opposition to the useful ones.” source
