It may, for instance, for all I know, be true that there are causal laws which insure that in the case of everything that is 'beautiful,' anything exactly like any of these things would, in this Universe, excite a particular kind of feeling in everybody to whom it were presented in a particular way: and if that were so, we should have a subjective predicate which satisfied the condition that, when a given thing possesses that predicate, it is impossible (in the causal sense) that any exactly similar thing should not also possess it.
