The view of things as above stated,--that all plurality is only apparent, that in the endless series of individuals, passing simultaneously and successively into and out of life, generation after generation, age after age, there is but one and the same entity really existing, which is present and identical in all alike;--this theory, I say, was of course known long before Kant; indeed, it may be carried back to the remotest antiquity. It is the alpha and omega of the oldest book in the world, the sacred *Vedas, whose dogmatic part, or rather esoteric teaching, is found in the *Upanishads.[2] There, in almost every page this profound doctrine lies enshrined; with tireless repetition, in countless adaptations, by many varied parables and similes it is expounded and inculcated. That such was, moreover, the fount whence Pythagoras drew his wisdom, cannot be doubted, despite the scanty knowledge we possess of what he taught. That it formed practically the central point in the whole philosophy of the Eleatic School, is likewise a familiar fact. Later on, the New Platonists were steeped in the same, one of their chief tenets being: _διὰ τὴν ἑνότητα ἀπάντων πάσας ψuχὰς mίαν εἶναι_. (All souls are one, because all things form a unity.) In the ninth century we find it unexpectedly appearing in Europe. It kindles the spirit of no less a divine than Johannes Scotus Erigena, who endeavours to clothe it with the forms and terminology of the Christian religion. Among the Mohammedans we detect it again in the rapt mysticism of the *Sûfi.[3] In the West Giordano Bruno cannot resist the impulse to utter it aloud; but his reward is a death of shame and torture. And at the same time we find the Christian Mystics losing themselves in it, against their own will and intention, whenever and wherever we read of them![4] Spinoza's name is identified with it. Lastly, in our own days, after Kant had annihilated the old dogmatism, and the world stood aghast at its smoking ruins, the same teaching was revived in Schelling's eclectic philosophy. The latter took all the systems of Plotinus, Spinoza, Kant, and Jacob Boehm, and mixing them together with the results of modern Natural Science, speedily served up a dish sufficient to satisfy for the moment the pressing needs of his contemporaries; and then proceeded to perform a series of variations on the original theme. The consequence is that in the learned circles of Germany this line of thought has come to be generally accepted; indeed even among people of ordinary education, it is almost universally diffused.[5] A solitary exception is formed by the University philosophers of the present day. They have the hard task of fighting what is called =Pantheism=. Being brought through the stress of battle into great embarrassment and difficulty, they anxiously catch now at the most pitiful sophisms, now at phrases of choicest bombast, so only they may patch together some sort of
