through knowing its effect, even though it is an intellect? Intellection, which is knowledge, is more fitting for it than action.
They know—as does every rational person—that the human soul does not grow weary from knowledge as it does from action. The same applies to the human body: if we can conceive of an action that involves no transformation or change, then we can all the more readily conceive of knowledge of it that involves no transformation or change. And if we can conceive of an action that entails no spatial motion, then it is all the more fitting and appropriate that knowledge of it should not entail such motion.
In short, whatever someone imagines to be a deficiency in knowledge—such as acquiring perfection through another, undergoing change, or being wearisome—applies all the more to its producing the other thing that is known. If action involves no deficiency but is instead a perfection, the same holds for knowledge. Moreover, the other thing mentioned is its effect and creation, which it itself has originated.
If it is said that its perfection comes through that other thing, then its perfection comes only through itself, since it is that thing’s originator. Its essence has therefore not depended on anything other than itself. We understand that, when something has no need of us, our knowing it is more perfect than our not knowing it, even though it has no need of us. Thus, even if something were supposed to exist that was not its effect, its knowing it would be more perfect than its not knowing it. How much more so, then, when that thing is its own effect?
Can it be said that someone who knows things through newly arising acts of knowledge—indeed, who comes to know them after they exist—is less perfect than someone who does not know them at all? How, then, could one who knows them neither before nor after they exist be more perfect?
Even if someone were to call knowledge of changing things change, motion, or the acquisition of perfection through another—whatever such label he might give it—when one who knows things is compared with one who does not, the former is more perfect in every case.
