Abstract

Suppose, then, we deny that there is a substrate for the various characteristics we associate with an ordinary object like a man or a table. The only option, it would seem, is to identify such objects with their characteristics. Put in another way, to reject the notion of bare substratum is to commit oneself to the claim that the constituents of objects are, one and all, characteristics. But if we are metaphysical realists, we want to say that characteristics are repeatable; and in the light of our claim that characteristics are the constituents of objects, this amounts to the view that the constituent of one object can be numerically identical with the constituent of another. But now we are forced to conclude that no two objects could ever have all their characteristics in common. Were two objects to exhibit precisely the same set of characteristics, all the constituents of one would be constituents of the other and vice versa; and where there is complete identity in constituents, we want to say, there are not two objects, but one.
