It has thus been shown that every attribute predicated of God either denotes the quality of an action, or—when the attribute is intended to convey some idea of the Divine Being itself, and not of His actions—the negation of the opposite. Even these negative attributes must not be formed and applied to God, except in the way in which, as you know, sometimes an attribute is negatived in reference to a thing, although that attribute can naturally never be applied to it in the same sense, as, e.g., we say, “This wall does not see.” Those who read the present work are aware that, notwithstanding all the efforts of the mind, we can obtain no knowledge of the essence of the heavens—a revolving substance which has been measured by us in spans and cubits, and examined even as regards the proportions of the several spheres to each other and respecting most of their motions—although we know that they must consist of matter and form; but the matter not being the same as sublunary matter, we can only describe the heavens in terms expressing negative properties, but not in terms denoting positive qualities. Thus we say that the heavens are not light, not heavy, not passive and therefore not subject to impressions, and that they do not possess the sensations of taste and smell; or we use similar negative attributes. All this we do, because we do not know their substance. What, then, can be the result of our efforts, when we try to obtain a knowledge of a Being that is free from substance, that is most simple, whose existence is absolute, and not due to any cause, to whose perfect essence nothing can be superadded, and whose perfection consists, as we have shown, in the absence of all defects. All we understand is the fact that He exists, that He is a Being to whom none of His creatures is similar, who has nothing in common with them, who does not include plurality, who is never too feeble to produce other beings, and whose relation to the universe is that of a steersman to a boat; and even this is not a real relation, a real simile, but serves only to convey to us the idea that God rules the universe; that is, that He gives it duration, and preserves its necessary arrangement. This subject will be treated more fully. Praised be He! In the contemplation of His essence, our comprehension and knowledge prove insufficient; in the examination of His works, how they necessarily result from His will, our knowledge proves to be ignorance, and in the endeavour to extol Him in words, all our efforts in speech are mere weakness and failure!
