ABSTRACT
This chapter assumes that the individuals exemplify the supervenient properties are composed of physical entities that exemplify the base properties. SPS is a very strong supervenience claim. It is, for example, stronger than the weak supervenience doctrine mentioned by Boghossian, stronger than global supervenience, and stronger than a thesis that is sometimes called “nomological supervenience.” Jerry Fodor appreciates that strong supervenience claims are in need of explanation. If intentional properties are physical properties or logical constructs out of physical properties, then that explains their supervenience on the physical. Fodor thinks that intentional properties are real and figure in scientific laws and therefore supervene on physical properties. The chapter provides the argument that Paul Boghossian asks for and thus an explanation of why we ought to believe in the supervenience thesis.
