Whereas the platonists tended to posit the existence of an ideal Form by which all the things under it are made intelligible, Aristotle critiques this position due to its apparent failure to account for the various senses of the word “good”. For Aristotle, good is an analogous term—meaning that it has many meanings according to its uses across different categories of thing.
