that just as we do not say that there is something additional in his essence by which he created the heavens, something else with which he created the elements, and a third with which he created the Intel- ligences, so we do not say that he has one attribute with which he exercises power, another with which he wills, a third with which he knows, and so on, but his essence is simple and one. 277

Four things must be removed from God: (1) corporeality, (2) affection, (3) potentiality, (4) resemblance to his creatures. The first we have already proved. The second implies change, and the author of the change cannot be the same as he who suffers the change and feels the affection. If then God were subject to affection, there would be another who would cause the change in him. So all want must be removed from him; for he who is in want of something is po- tential, and in order to pass into actuality requires an agent having that quality in actu. The fourth is also evident; for resemblance in- volves relation. As there is no relation between God and ourselves, there is no resemblance. Resemblance can exist only between things of the same species. All the expressions including "existent" are applied to God and to ourselves in a homonymous sense (cf. above, p. 240). The use is not even analogical; for in analogy there must be some resemblance between the things having the same name, but not so here. Existence in things which are determined by causes (and this includes all that is not God), is not identical with the essence of those things. The essence is that which is expressed in the definition, whereas the existence or non-existence of the thing so defined is not part of the definition. It is an accident added to the essence. In God the case is different. His existence has no cause, since he is a necessary existent; hence his existence is identical with his essence. So we say God exists, but not with existence, as we do. Similarly he is living, but not with life; knowing, but not with knowledge; pow- erful, but not with power; wise, but not with wisdom. Unity and plurality are also accidents of things which are one or many as the case may be. They are accidents of the category of quantity. God, who is a necessary existent and simple cannot be one any more than many. He is one, but not with unity. Language is inadequate to express our ideas of God. Wishing to say he is not many, we have to say he is one; though one as well as many pertains to the accidents
