Should the analyses of Taine and Lewes prove successful at last, and be accepted by the authorities in speculative philosophy, idealism, as a philosophy, must disappear. The days of metaphysics in the old sense, will be numbered; the German schools from Kant to Hegel will become obsolete; Jacobi's doctrine of faith, Fichte's doctrine of the absolute Ego, Schelling's doctrine of intellectual intuition, will be forgotten; Cousin's influence will be gone; the fundamental ideas of Transcendental teachers, French, English, American, will be discredited; and the beliefs founded on them will fade away. There will, however, be no cause to apprehend the personal, social, moral or spiritual demoralization which the "Sensualist" doctrines of the last century were accused of encouraging. The attitude of the human mind towards the great problems of destiny has so far altered, the problems themselves have so far changed their face, that no shock will be felt in the passage from the philosophy of intuition to that of experience. Questions respecting the origin, order and regulation of the world, the laws of character, the constitution of society, the conditions of welfare, the prospects and relations of the individual, are put in new forms, discussed by new arguments, and answered by new assurances. The words atheism and materialism have passed through so many definitions, the conceptions they stand for have become so completely transformed by the mutations of thought, that the ancient antipathies are not longer excusable; the ancient fears are weak. The sanctities that once were set apart in ideal shrines will be perfectly at home among the demonstrated facts of common life.
