 There are, however, problems with Yablo’s defense of Vallentyne’s contractionist approach to intrinsicality. One problem, discussed in Parsons 2007 and Marshall 2014, is that, on Yablo’s version of contractionism, we need to be able to make sense of sentences like ‘In \(w\), Prince Philip is not a husband’, where \(w\) is the world consisting of just Prince Philip. Making sense of such sentences, however, is difficult without appealing to the distinction between intrinsic and non-intrinsic properties. Appealing to this distinction when interpreting Yablo’s account, however, would render it circular. Further criticism and discussion of Yablo’s account is given in Parsons 2007 and Marshall 2014. For further discussion of Vallentyne’s account, see Marshall 2013.
