"Linus, in a passage which has been preserved by Stobaeus, exactly expresses the notion afterwards adopted by Spinoza: 'One sole energy governs all things; all things are unity, and each portion is All; for of one integer all things were born; in the end of time all things shall again become unity; the unity of multiplicity.' Orpheus, his disciple, taught no other doctrine." According to Pythagoras, "an adept in the Orphic philosophy," "the soul of the world is the Divine energy which interpenetrates every portion of the mass, and the soul of man is an efflux of that energy. The world, too, is an exact impress of the Eternal Idea, which is the mind of God." John Scotus Erigena taught that "all is God and God is all." William of Champeaux, again, two hundred years later, maintained that "all individuality is one in substance, and varies only in its non-essential accidents and transient properties." Amalric of Bena and David of Dinant followed the theory out "into a thoroughgoing Pantheism." Amalric held that "All is God and God is all. The Creator and the creature are one Being. Ideas are at once creative and created, subjective and objective. God is the end of all, and all return to Him. As every variety of humanity forms one manhood, so the world contains individual forms of one eternal essence." David of Dinant only varied upon this by "imagining a corporeal unity. Although body, soul, and eternal substance are three, these three are one and the same being." Giordano Bruno maintained the world of sense to be "a vast animal having the Deity for its living soul." The inanimate part of the world is thus excluded from participation in the Deity, and a conception that our minds can embrace is offered us instead of one which they cannot entertain, except as in a dream, incoherently. But without such a view of evolution as was prevalent at the beginning of this century, it was impossible to see "the world of sense" intelligently, as forming "a vast animal." Unless, therefore, Giordano Bruno held the opinions of Buffon, Dr. Erasmus Darwin, and Lamarck, with more definiteness than I am yet aware of his having done, his contention must be considered as a splendid prophecy, but as little more than a prophecy. He continues, "Birth is expansion from the one centre of Life; life is its continuance, and death is the necessary return of the ray to the centre of light." This begins finely, but ends mystically. I have not, however, compared the English translation with the original, and must reserve a fuller examination of Giordano Bruno's teaching for another opportunity. Spinoza disbelieved in the world rather than in God. He was an Acosmist, to use Jacobi's expression, rather than an Atheist. According to him, "the Deity and the Universe are but one substance, at the same time both spirit and matter, thought and extension, which are the only known attributes of the Deity."
