 We now turn to the notion of intrinsicality characterised by the characterisations listed in section  1.  Or perhaps better, we now turn to the notions of intrinsicality characterised by these characterisations, since, while Lewis thought that each of these characterisations characterise a single notion of intrinsically, it is plausible that they characterise different notions. In this subsection, we will discuss the notion characterised by the first characterisation which involves aboutness. In the next two subsections, we will discuss the notions characterised by the other two characterisations.
