 Instead of analysing intrinsicality in terms of perfect naturalness, one might try to analyse it in terms of non-disjunctivity, where non-disjunctivity is regarded as an objective metaphysical feature of properties rather than merely a syntactical feature of predicates. The most prominent attempt to do this is the account of Langton and Lewis 1998. (A similar theory is in an appendix to Zimmerman 1997.)
