Sankarâchârya, an axiom in accordance with the dogmas of the sacred books. Matter exists [say these philosophers], but not of an existence such as is imagined by the vulgar; it exists but it has no essence independent of intellectual perceptions; for existence and perceptibility are, in this case, convertible terms. The sage knows that appearances and their exterior sensations are purely illusory and that they would vanish into nothingness, if the Divine energy which alone sustains them was for an instant suspended.[504] I beg the disciples of Kant to give attention to this passage, and to remember what Plato has said of the same, that, sometimes matter exists and sometimes it does not exist[505]; as Justin the martyr, and Cyril of Alexandria have reproached him for it; and as Plutarch and Chalcidius have strongly remarked it,[506] in seeking to excuse this apparent contradiction. Let us endeavour now to call attention to the point where Kant is led astray. This point, in the philosophical course that this savant meant to pursue, seemed at first of very slight importance; but the deviation that it causes, although small and almost imperceptible at the first instant, determines none the less a divergent line, which, turning aside more and more from the right line proportionably as it is prolonged, is found to strike at an enormous distance from the mark where Kant hoped it would arrive. This deviating point――who would have believed it――is found in the misinterpretation and the misapplication of a word. All the attention of the reader is required here. What I am about to say, in demonstrating the error of the German philosopher, will serve to supplement all that I have said pertaining to the doctrine of Pythagoras.
