It happens to be the case that we cannot, in our language, refer to the sensible properties of a thing without introducing a word or phrase which appears to stand for the thing itself as opposed to anything which may be said about it. And, as a result of this, those who are infected by the primitive superstition that to every name a single real entity must correspond assume that it is necessary to distinguish logically between the thing itself and any, or all, of its sensible properties. And so they employ the term “substance” to
refer to the thing itself. But from the fact that we happen to employ a single word to refer to a thing, and make that word the grammatical subject of the sentences in which we refer to the sensible appearances of the thing, it does not by any means follow that the thing itself is a “simple entity,” or that it cannot be defined in terms of the totality of its appearances. It is true that in talking of “its” appearances we appear to distinguish the thing from the appearances, but that is simply an accident of linguistic usage. Logical analysis shows that what makes these
“appearances” the “appearances of” the same thing is not their relationship to an entity other than themselves, but their relationship
to one another. The metaphysician fails to see this because he is misled by a superficial grammatical feature of his language.
