 These role-theoretic specifications of what it is to be an object will have consequences with respect to the Extension Question and the Contrast Question. If literally every thing at all is eligible for reference or quantification or thought, for example, then literally every thing would be an object, a thesis in line with the Umbrella View. If, on the other hand, some items are not eligible for reference or quantification or thought, then such items would fall under non-object, and the category object would turn out to have a contrast or complement. Similarly, if , say, both concrete material objects, abstract propositions are eligible for reference or quantification or thought, then items of both sorts would fall under the extension of  object.[22]
