 Supersubstantivalists will deny that exact location is a fundamental relation. Others might take aim at McDaniel's recombination principle. Let F be the property being round and let G be the property not being square. These may seem to be accidental and intrinsic. But if they are, and if exact location is fundamental, then McDaniel's principle tells us that it is possible for a round object to be exactly located at a square region, which some might take as a reductio of (7). McDaniel (2007b) and Skow (2007), however, take this to show that the given shapes are not intrinsic properties. For a more detailed discussion of recombination principles such as (7), and a defense of the view that shapes are intrinsic, see Kleinschmidt (2015).
