Is the intelligible (Being) then so varied and manifold? It is indeed varied, but it is simultaneously simple; it is both one and manifold; for reason (which is the essence of the universal Soul), is both one and manifold. The universal (Being) is also one; though any difference in it (in this sense, that it contains different essences), results from its own constitution; the difference inheres in its nature, for it could not belong to non-being. The constitution of Essence is such as to be inseparable from unity; unity is present wherever essence is, and the one Essence subsists in itself. It is indeed possible that an essence which in a certain respect is separated from another essence, is, however, entirely present with it. But there are different kinds of presence; first, when sense-things are present with intelligible things, at least to those to which they can be present; second, when intelligible entities are present to each other; likewise, when the body is present to the soul; another, when a science is present to the soul; further, when a science is present to another science, and both coexist in the same intelligence; last, when a body is present to another body. HOW VARIOUS THINGS CAN PARTICIPATE IN THE SAME PRINCIPLE. 12. When a sound resounds in the air, and when it constitutes a word, the ear that is present hears and perceives this sound and this word, especially if the place be quiet. If another ear should come to be in this place, the sound and the word approach it likewise, or rather, this ear will approach the word. Suppose also that several eyes consider the same object; all are filled with its sight, although this object occupy a determinate place. Thus the same object will impress different organs with different perceptions, because the one is an eye, and the other is an ear. Likewise, all the things that can participate in the soul do participate therein, but each receives a different power from one and the same principle. The sound is everywhere present in the air; it is not a divided unity, but a unity present everywhere, entirely. Likewise, if the air receive the form of the visible object, it possesses it without division, for, in whatever place the eye should place itself, it perceives the form of the visible object; at, least, according to our opinion, for not all philosophers agree herewith. We give these examples to explain how several things may participate in one and the same principle. Besides, the example of the sound suffices to demonstrate what we here wish to explain; namely, that the entire form is present in the entire air; for all men would not hear the same thing, if the word uttered by the sound were everywhere entire, and if each ear did not likewise hear it entire. Now if in this case the entire word spread in the entire air, without some definite part of the word being united to a certain part of the air, and some other part of the word being united with another
