Postulating logically compound properties accounts for our understanding of complex predicates and how they differ from simple ones

It is easy to construct complex predicates. But whether there really are corresponding properties of this kind is a much more difficult and controversial issue, tightly bound to the sparse/abundant distinction. In the sparse conception the tendency is to dispense with them. This is understandable since in this camp one typically postulates properties in rebus for empirical explanatory reasons. But then, if we explain some phenomena by attributing properties \(F\) and \(G\) to an object, while de
