 One way then to charge that age is an arbitrary means of distinguishing those qualified and those not qualified to have rights is that there is, in fact, no real division of capacities. (Cohen 1980, 48) However another way to make the charge of arbitrariness in turns on the idea that dividing lines as such—‘any’ lines—are arbitrary. Thus, either it will be said that this age is the wrong dividing point or that using any age is wrong. The first objection may concede that there is a better age to be used, just as the second objection may concede that there is a way, better than using age, to mark the division. The initial and obvious reply to the second objection is that age as such is not the issue but rather the reliable correlation of age with the acquisition of those capacities that qualify a person for the attribution of rights. Some liberationists may thus not dispute that there should be a threshold age—one beyond which adult rights are acquired—but think that the conventional or orthodox threshold is fixed too late. Liberationists may also simply deny that there should be any threshold on the grounds that there just is no difference between children and adults in respect of their respective capacities for any threshold age to mark. This version of the arbitrariness claim concedes that if age functions as a threshold it does so only inasmuch as it reliably correlates with the acquisition of capacities which are necessary qualifications for the possession of rights. In sum, the arbitrariness claim amounts either to the denial that the acquisition of the specified capacities does correlate with the threshold in question or to the denial that there is any age at which the capacities are acquired.
