 There is a debate in the literature on properties between the abundant conception of properties, according to which there is a property corresponding to every natural language predicate and, more generally, every class of individuals, and the sparse conception of properties, according to which a predicate expresses a property only if the objects that predicate is true of resemble one another in an intrinsic way. If the abundant conception is true, then our first question may seem trivial: Existence is a property of individuals because sentences like ‘Bill Gates exists’ are grammatical and there is a class of all individuals and hence a corresponding property of existing. It seems, then, that our first question has bite only if the sparse conception is true. But appearances deceive. As we will see in section 1, there is a controversy as to whether the logical form of a sentence like ‘Bill Gates exists’ is really subject-predicate in structure and so whether the English verb ‘exists’ really is predicated of individuals. The question whether existence is a property of individuals is perhaps more straightforward on the sparse conception of properties. But the question can still be raised even on the abundant conception as the question whether existence is a property of individuals involved in our talk of what exists and what does not, which is then a question about the logical form of the sentences used in our existential discourse.
