leading doctrine of the Vedas and Puranas, the doctrine of Mâyâ, by which really nothing else is understood than what Kant calls the phenomenon in opposition to the thing in itself; for the work of Mâyâ is said to be just this visible world in which we are, a summoned enchantment, an inconstant appearance without true being, like an optical illusion or a dream, a veil which surrounds human consciousness, something of which it is equally false and true to say that it is and that it is not. But Kant not only expressed the same doctrine in a completely new and original way, but raised it to the position of proved and indisputable truth by means of the calmest and most temperate exposition; while both Plato and the Indian philosophers had founded their assertions merely upon a general perception of the world, had advanced them as the direct utterance of their consciousness, and presented them rather mythically and poetically than philosophically and distinctly. In this respect they stand to Kant in the same relation as the Pythagoreans Hicetas, Philolaus, and Aristarchus, who already asserted the movement of the earth round the fixed sun, stand to Copernicus. Such distinct knowledge and calm, thoughtful exposition of this dream-like nature of the whole world is really the basis of the whole Kantian philosophy; it is its soul and its greatest merit. He accomplished this by taking to pieces the whole machinery of our intellect by means of which the phantasmagoria of the objective world is brought about, and presenting it in detail with marvellous insight and ability. All earlier Western philosophy, appearing in comparison with the Kantian unspeakably clumsy, had failed to recognise that truth, and had therefore always spoken just as if in a dream. Kant first awakened it suddenly out of this dream; therefore the last sleepers (Mendelssohn) called him the “all-destroyer.” He showed that the laws which reign with inviolable necessity in existence, _i.e._, in experience generally, are not to be applied to deduce and explain _existence itself_ that thus the validity of these laws is only relative, _i.e._, only arises after existence; the world of experience in general is already established and present; that consequently these laws cannot be our guide when we come to the explanation of the existence of the world and of ourselves. All earlier Western philosophers had imagined that these laws, according to which the phenomena are combined, and all of which—time and space, as well as causality and inference—I comprehend under the expression “the principle of sufficient reason,” were absolute laws conditioned by nothing, _æternæ veritates_; that the world itself existed only in consequence of and in conformity with them; and therefore that under their guidance the whole riddle of the world must be capable of solution. The assumptions made for this purpose, which Kant criticises under the name of the Ideas of the
