 The bundle theory is a theory about objects according to which objects are composed of items of a different kind or category (namely,  properties).[26]  So the bundle theory suggests that object has a contrast or complement. The bundle theory also suggests this broad answer to the Extension Question: whenever there is a bundle of coinstantiated universals (or, alternatively, compresent tropes), there is an object. The extension of object includes all and only the bundles, and what bundles there are is determined by which immanent universals or tropes stand in the coinstantiation or compresence  relation.[27]
