Under these circumstances, it has become an impossibility for religion and the moral interest as guardians of the highest and most sacred acquisitions of mankind, and still more for theology and ethics as the scientific representations of religion and morality, to remain idle spectators. It would certainly be more agreeable to them, and more profitable, if they could delay their judgment until the question became better cleared up. For the whole question presented by Darwin has not yet passed beyond the stage of problems and attempts at solution; and there is always something unsatisfactory in being compelled to deal with theories which in their fundamentals are still hypotheses. But since all tendencies of the present which are hostile to Christianity and to the theistic view of the world, from the most extreme materialism up to the most sublime monism (as pantheism and materialism of to-day have begun to call themselves), seemingly with the confidence of complete victory, take possession of Darwinism as the solid ground from which they hope to destroy all and every belief {20} connected with faith in a living creator and master of the world, it has also become impossible for those to whom the religious and ethical acquisitions of mankind are a sacred sanctuary to take any longer a reserved and expectant position. Silence now would be looked upon only as an inglorious retreat; and thus nothing remains but openly to face the question: What position must religion and morality take in reference to the Darwinian theories? In order to treat of the question with that objectivity which it requires, we have to begin with a synopsis of the theories themselves. In this representation we have to discriminate strictly between the merely scientific theories and the naturo-philosophical and metaphysical supplements and conclusions which have been brought into connection with them. For precisely in the mixing of the most different problems which are to be considered here, lies the main cause of the confused and superficial judgment which is so often heard upon these questions. * * * * * {21} PART I. * * * * * THE THEORIES OF DARWIN. * * * * * {23} BOOK I.
