Grammar suggests that you and I are more or less permanent entities with changing states, but the permanent entities are unnecessary, and the changing states suffice for saying all that we know on the matter. Exactly the same sort of thing applies to physical objects. If you go into a shop and buy a loaf of bread, you think that you have bought a "thing" which you can bring home with you. What you have in fact bought is a series of occurrences linked together by certain causal laws.
