 Composition. Grounding considerations and Bradley’s regress have found their application in the discussion of the problem of composition of objects. Brzozowski (2008) has recently posed the following question concerning the location of composite objects: does the location of a composite object derive from the location of its proper parts, or not? (Brzozowski 2008: 193). Either way, Brzozowski takes it that we get unappealing consequences. The first horn of the dilemma is that if indeed the location of composite objects is derived from their proper parts, the possibility of spatio-temporal gunk objects (composite objects whose parts are themselves composite objects) would have to be denied. If, on the other hand, the location of composite objects is not derived from their proper parts, then brute metaphysical necessities connecting the location of composite objects with the locations of their proper parts must be posited. Brzozowski argues in favor of the first horn of the dilemma, and part of his argument relies on applying a Bradley-type argument to the location of gunk objects. His main thought is that there would be a serious problem of location of gunk objects since “even though at each level of the series of decomposition we can explain the location of a composite object by appealing to the location of a proper part, it is left unexplained how any object in the series is located in space-time. Given the piecemeal story, there is no way for the totality of location relations to be grounded…” (Brzozowski 2008: 201).  As we can see, Brzozowski here relies on some version of Cameron’s WF principle described above.
