 The main objections to the ‘universals’ form of the theory rest on its apparent commitment to the Identity of Indiscernibles, for if an object is no more than a bundle of properties, then if a and b have exactly the same properties, they are the same bundle. Whether it does carry this commitment may depend on whether one allows spatial points as particulars, in addition to the properties that are universal. If one did, then the universal theories would not entail the identity of indiscernibles, for the same universals could be in two bundles by being at two different locations.
