This reminds me of a Peter Geach quote: "The moral philosophers known as Objectivists would admit all that I have said as regards the ordinary uses of the terms good and bad; but they allege that there is an essentially different, predicative use of the terms in such utterances as pleasure is good and preferring inclination to duty is bad, and that this use alone is of philosophical importance. The ordinary uses of good and bad are for Objectivists just a complex tangle of ambiguities. I read an article once by an Objectivist exposing these ambiguities and the baneful effects they have on philosophers not forewarned of them. One philosopher who was so misled was Aristotle; Aristotle, indeed, did not talk English, but by a remarkable coincidence ἀγαθός had ambiguities quite parallel to those of good. Such coincidences are, of course, possible; puns are sometimes translatable. But it is also possible that the uses of ἀγαθός and good run parallel because they express one and the same concept; that this is a philosophically important concept, in which Aristotle did well to be interested; and that the apparent dissolution of this concept into a mass of ambiguities results from trying to assimilate it to the concepts expressed by ordinary predicative adjectives."
