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. BOOK I. THE PURELY SCIENTIFIC THEORIES. THE SCIENTIFIC PROBLEM. The interesting problem which underlies Mr. Darwin's theories is the answer to the question: How did the different species of organic beings on the earth originate? We find ourselves in the midst of an endless variety of organic beings, animals and plants; we see ourselves, so far as regards the entire physical part of our being, in relationship with this organic world especially with the organization and physical functions of the animal body. The organic individuals come and go. They originate by being begotten by and born of individuals of the same kind, or they spring up through the formation of germs and buds; and they produce in the same way new individuals, that resemble them in all essential characteristics. Like always begets like, so far as our observations go. But not only the individuals, but even the species to which they belong, must -have originated at some definite period of time—and, indeed, as geology tells us, not all at once, but in a long series, which stretched through immeasurable epochs of the earth's history. Thus we come face to face with the question, already put, which we can now formulate more precisely: How did the first individuals of each organic species come into existence? No human being ever has observed, nor ever could observe, the origination of a new species, because man, as it seems, did not appear on the earth until all the For this reason, other organisms were in existence. the scientists for a long time thought it unprofitable to occupy themselves with this question; and even in our time a great many of them declare the question to be absolutely insolvable, and every attempt at answering it to be an unjustifiable use of hypotheses. But the impulse toward investigation admits of no limitation so long as there is any probability of extending its field of action. Especially in the province of nature, so many things which could not be discovered by mere observation have been traced indirectly, and so many important and established facts have been added to our stores of knowledge, by first starting from hypothetical premises, that man has again and again endeavored to approximate an answer to the question of the origin of species by taking the indirect course of hypothesis and induction, whenever the direct way of observation did not lead to any result. Religion of course gives a solution to the problem by stating that the species have been originated by the creative act of God. It is wrong to say that this solution is opposed to the above-mentioned impulse toward investigation; for this solution suffices for religion, whether a natural progress in the origination of species be established or not. For, to the believer in religion, the whole universe, with all its objective phenomena and growth, is the work of God as well as the individuals of the already existing species; and a |
