Meta Ontology

Several authors have recently claimed that the distinction between intrinsic and extrinsic properties is hyperintensional, i.e., that there are cointensional properties P and Q, such that P is intrinsic, while Q is extrinsic. In this paper, I aim to defend the classical view that whenever P and Q are cointensional properties, then P and Q are either both intrinsic or both extrinsic. I first argue that the standard characterization of the intrinsic/extrinsic distinction involves dependence claims: intrinsic properties are those properties whose instantiation by x only depends on what x is like in itself, whereas extrinsic properties are those properties whose instantiation by x may also depend on what other individuals are like. I then consider a number of examples supposed to show that the intrinsic/extrinsic distinction is hyperintensional and argue that none of them succeeds if the dependence characterization of the distinction is taken seriously.
