 If the answer to the ontological question is ‘everything’, if there is a category under which all things fall and if that category is picked out by ‘object’ by definition (as per the Umbrella View), then there is one shared answer to both the extension and the ontological questions. This is one consequence of the Umbrella View. But it might turn out that every thing is an object, even if not by definition. A physicalism according to which every thing is a material object, for example, would appear to entail that every thing is an object. But this entailment need not hold because of the definition of ‘object’; it might hold, instead, on substantive and general theoretical grounds having nothing to do with definitions at all.
