Metaphysics

In the debate about philosophical universals, Quinton defended a variety of nominalism that identifies properties with a set of "natural" classes. David Malet Armstrong has been strongly critical of natural class nominalism: Armstrong believes that Quinton's 'natural' classes avoid a fairly fundamental flaw with more primitive class nominalisms, namely that it has to assume that for every class you can construct, it must then have an associated property. The problem for the class nominalist according to Armstrong is that one must come up with some criteria to determine classes that back properties and those which just contain a collection of heterogeneous objects.
Quinton's version of class nominalism asserts that determining which are the natural property classes is simply a basic fact that is not open to any further philosophical scrutiny. Armstrong argues that whatever it is which picks out the natural classes is not derived from the membership of that class, but from some fact about the particular itself.
While Quinton's theory states that no further analysis of the classes is possible, he also says that some classes may be more or less natural—that is, more or less unified than another class. Armstrong illustrates this intuitive difference Quinton is appealing to by pointing to the difference between the class of coloured objects and the class of crimson objects: the crimson object class is more unified in some intuitive sense than the class of coloured objects.
In Quinton's 1957 paper, he sees his theory as a less extreme version of nominalism than that of Willard van Orman Quine, Nelson Goodman and Stuart Hampshire.
