Fine's account of the Argument from Relatives differs very much from that of G.E.L. Owen's account in his ‘A proof in the Peri Idēon’. In this chapter, Fine explores in more detail Owen's account, and the points on which they disagree. Fine argues that the Argument from Relatives assumes that the possibility of knowledge requires non-homonymous properties, and that Plato shares the assumption that F-ness can only be explained if there is some one thing F that is the same in all cases. Fine's conclusion reinforces that of Ch. 10, i.e. that neither Plato nor the Argument from Relatives posit forms for semantic reasons.
