γ. This is Bruno’s fundamental idea. He says: “To recognize this unity of form and matter in all things, is what reason is striving to attain to. But in order to penetrate to this unity, in order to investigate all the secrets of Nature, we must search into the opposed and contradictory extremes of things, the maximum and the minimum.” It is in these very extremes that they are intelligible, and become united in the Notion; and this union of them is infinite Nature. “To find the point of union is not the greatest matter; but to develop from the same its very opposite, this is the real and the deepest secret of the art.”[79] It is saying much if we speak of knowing the development of the Idea as a necessity of determinations; we shall see later how Bruno proceeded to do this. He represents the original principle, which is elsewhere known as the form, under the Notion of the minimum, which is at the same time the maximum—One, which at the same time is All; the universe is this One in All. In the universe, he says, the body is not distinguished from the point, nor the centre from the circumference, nor the finite from the infinite, nor the maximum from the minimum. There is nothing but centre point; or the centre point is everywhere and in everything. The ancients expressed the same by saying of the Father of the gods, that he really had his dwelling-place in every point of the universe. It is the universe that first gives to things true reality; it is the substance of all things, the monad, the atom, the spirit poured out on all things, the innermost essence, the pure form.[80]
