If the empirical. philosophers have hitherto failed to prove the progress of moral conceptions (which may be inciple of evolution), the fault lies to a great extent with the speculative, i.e., the . nonscientific philosophers. They have so strongly denied the empirical origin of man's moral feelings; they have gone to such subtle reasoning in order to assign a supernatural origin to the moral sense; and they have spoken so much about "the destination of man," the "way of his existence," and "the aim of Nature," that a reaction against the mythological and metaphysical conceptions which had risen round this question was unavoidable.

Let us, then, dwell a little longer upon the results obtaine...
