Abstract
In this chapter, I will deal with the problem of second-order quantification . I distinguish two senses of ‘second-order quantification’: (i) metaphysically second-order quantification, which occurs whenever we quantify into the position of individual variables of a domain that includes properties or sets and (ii) logically second-order quantification, i.e. cases in which we quantify into the position of variables for first-order predicates. Both kinds of second-order quantification may be used to establish the existence of universals and thus should be discussed. In the first part of Chap. 6, I deal with metaphysically second-order quantification and argue that any metaphysically second-order sentence that seems to refer to properties, e.g., ‘humility is a virtue’ and ‘red resembles orange more than blue’, has an ontologically fundamental first-order paraphrase . I develop and apply what I call the ‘method of grounded paraphrase’. In the second part, I discuss logically second-order quantification. I explain and defend the plausibility of two arguments of the ostrich against the line of reasoning that derives the existence of properties from logically second-order quantification. The first argument aims to cast doubts on the very intelligibility of quantification into the predicate position, the second aims to show that predicates can play an important semantic role even when they do not ‘stand for’ extra-linguistic entities like properties. In the end, I will maintain that even when one rejects these last two arguments, the priority nominalist may not be concerned about logically second-order predication, because all second-order truths are grounded in first-order truths.

Notes
- 1.
Since red, orange and blue are clearly not the lowest determinate properties (and so, they are not sparse, but merely abundant properties), one could prefer (as does Rodriguez-Pereyra 2002) to substitute (2) by ‘scarlet is more similar to vermillion than to French blue’. Nothing relevant in the argument of this chapter depends on this point.
- 2.
Rodriguez-Pereyra (2015) follows a similar line of reasoning to defend his Resemblance Nominalism. He suggests that the truthmaker of ‘courage is a virtue’ should be expressed as ‘any courageous person is partially virtuous at least partly in virtue of being courageous’. I disagree with this suggestion, because I don’t think we need partial grounding if we accept the ‘partially virtuous’ predicate: if having one positive quality suffices for being partially virtuous, then a being courageous fully grounds a being partially virtuous.
- 3.
I thank Rodriguez-Pereyra for this counterexample. In fact, if we take the counterexample seriously, one option could be rejecting the truth of the original sentence. As a result, the priority nominalist would no longer be forced to offer a paraphrase.
- 4.
One could be sceptical about the use of grounding in the claim that ‘b is F in virtue of a being F’. As we stressed several times above, grounding is usually not conceived as a relation of causal determination. But it seems clear that inheritance is also not a kind of causation. It sounds odd to say that an organism causes its offspring to have a property. If a cat a has an offspring b, a does not ‘cause’ b to be a cat too. See the third example in Schaffer (2012) for a case of grounding applied to biological inheritance.
- 5.
However, as Rayo and Yablo (2001:77) have shown, even the Platonist could be interested in deflating the ontological consequences of second-order theories.
- 6.
This argument is very adequately explained and improved by A. Parisi (forthcoming).
- 7.
It is worth mentioning that the priority nominalist does not have to argue that predicative quantification must be interpreted substitutionally. Rayo and Yablo’s account of quantification e.g. is neither objectual nor substitutional.
