Abstract
I think there are no quality individuals which, in the way required, have the characteristics they ascribe to them. Without these features quality individuals will not serve the purpose for which Matthews and Cohen introduce them. So quite apart from the difficulties there are in Plato's account of predication, not only is Aristotle's account unacceptable as it stands, but also Matthews and Cohen's alteration offers no improvement. Indeed, it seems to me that no account of predication can be constructed which will avoid a distinction between individuals and qualities which are not individuals, which some philosophers seem to find so distasteful. Matthews and Cohen's introduction of quality individuals is just one further attempt to avoid this distinction. In order to bring out what is wrong with the notion of quality individual I shall describe the context in which it is introduced and then discuss the mistakes I find in it.
