 If Lewis’s three characterisations concerning intrinsicality characterise different notions, the three characterisations described in section  1.2  concerning having a property in an intrinsic fashion also characterise different notions. In order to distinguish these notions, we may employ these characterisations to define having a property in a duplication preserving fashion, having a property in an interior fashion (relative to different entailment relations), and having a property in a local fashion.
