On the foundation of a supposed elevation of organisation in the whole living population of any epoch, as compared with that of its predecessor, and a supposed complete difference in species between the populations of any two epochs (neither of which suppositions has stood the test of further inquiry), the author of this speculation based his conclusion that the Creator had, so to speak, improved upon his thoughts as time went on; and that, as each such amended scheme of creation came up, the embodiment of the earlier divine thoughts was swept away by a universal catastrophe, and an incarnation of the improved ideas took its place.  Only after the last such “wreck” thus brought about, did the embodiment of a divine thought, in the shape of the first man, make its appearance as the ne plus ultra of the cosmogonical process.

I imagine that Louis Agassiz, the genial backwoodsman of the science of my young days, who did more to open out new tracks in the scientific forest than most men, would have been much surprised to learn that he was preaching the doctrine of the Cabbala, pure and simple.  According to this modification of Neoplatonism by contact with Hebrew speculation, the divine essence is unknowable—­without form or attribute; but the interval between it and the world of sense is filled by intelligible entities, which are nothing but the familiar hypostatised abstractions of the realists.  These have emanated, like immense waves of light, from the divine centre, and, as ten consecutive zones of Sephiroth, form the universe.  The farther away from the centre, the more the primitive light wanes, until the periphery ends in those mere negations, darkness and evil, which are the essence of matter.  On this, the divine agency transmitted through the Sephiroth operates after the fashion of the Aristotelian forms, and, at first, produces the lowest of a series of worlds.  After a certain duration the primitive world is demolished and its fragments used up in making a better; and this process is repeated, until at length a final world, with man for its crown and finish, makes its appearance.  It is needless to trace the process of retrogressive metamorphosis by which, through the agency of the Messiah, the steps of the process of evolution here sketched are retraced.  Sufficient has been said to prove that the extremist realism current in the philosophy of the thirteenth century can be fully matched by the speculations of our own time.
