 Few have been led by the use of the words furniture or silverware to conclude that there is a category of stuff or matter which is distinct from things, nor have many others denied that there is such a strong distinction based on the interchangeability of phrases like ‘get your stuff off my desk!’ with ‘get your things off my desk!’ But, as we will discuss, the apparent metaphysical triviality of category (a) could very well undermine the contention that concrete mass nouns do in fact have metaphysical import, since there is little or no grammatical difference between terms in category (a) or  (b).[11]  This is discussed more in  Section 4  and in  Supplement: Non-Atomicity and its Relevance to the Mass/Count Distinction.
