 If, on the other hand, the problem is isolated to the case at hand, we are owed an explanation of what makes this case so special. MacBride complains that if the ‘explanatory task’ is that of accounting for the capacity of compresence to relate, being told that compresence has that capacity ‘by nature’, will not do. Perhaps he is right about this. But, then, the explanatory task is arguably not that one, but rather the task of accounting for the possible existence of concrete objects, (contingently) made up from tropes. If this is the explanatory task, it is far from clear why positing a special kind of (relational) trope that is ‘by nature’ apt to perform its relating function, will not do as an explanation.
