 The solution points to another difference between integral wholes and universals. As Abelard puts it, every integral whole “draws together” (comprehendere) some quantity (Dialectica, 546.21–27). The suggestion is that when some items compose an integral whole, that whole will be measurable with respect to some quantity or other. The integral whole that is measured by some quantity need not be composed out of material elements. Consider the mereological sum of the angel Gabriel and the angel Michael. If this sum is a whole (and there seems to be no reason to deny this), it seems it is an integral whole. However, there are some integral wholes which do not seem to embrace any quantity, namely, thoughts and actions. So there is need to locate yet another difference between universal wholes and integral wholes.
