1. Scotus’ own Reason

30. I prove the first: taking some determinate grace, say a, I ask by way of progressive ascent: either there is a stand at some highest grace, and then the conclusion is gained; or there is no stand and an infinite process is possible. And then it follows, in the latter case, that the more some grace exceeds a certain grace a the more perfect it is; and so a grace that exceeds infinitely is more perfect infinitely and will thus in itself be intensively infinite; and since it would be seen by the divine intellect as a single creatable thing, it can be created in a single creation. And thus, setting aside what the inference shows to be impossible, namely that there does exist such an infinite grace [sc. a grace to which there can be no equal, n.28], the conclusion is gained that the highest grace can be created by a single act of creation [cf. n.16], just as it is seen by the divine intellect to be a single creatable thing.
