What then are the truths taught us in these chapters? The first is that there has been a creation, that things now existing have not just grown of themselves, but have been called into being by a presiding intelligence and an originating will. No attempt to account for the existence of the world in any other way has been successful. A great deal has in this generation been added to our knowledge of the efficiency of material causes to produce what we see around us; but when we ask what gives harmony to these material causes, and what guides them to the production of certain ends, and what originally produced them, the answer must still be, not matter but intelligence and purpose. The best informed and most penetrating minds of our time affirm this. John Stuart Mill says: "It must be allowed that in the present state of our knowledge the adaptations in nature afford a large balance of probability in favour of creation by intelligence." Professor Tyndall adds his testimony and says: "I have noticed during years of self-observation that it is not in hours of clearness and vigour that [the doctrine of material atheism] commends itself to my mind--that in the hours of stronger and healthier thought it ever dissolves and disappears, as offering no solution of the mystery in which we dwell and of which we form a part." There is indeed a prevalent suspicion, that in presence of the discoveries made by evolutionists the argument from design is no longer tenable. Evolution shows us that the correspondence of the structure of animals, with their modes of life, has been generated by the nature of the case; and it is concluded that a blind mechanical necessity and not an intelligent design rules all. But the discovery of the process by which the presently existing living forms have been evolved, and the perception that this process is governed by laws which have always been operating, do not make intelligence and design at all less necessary, but rather more so. As Professor Huxley himself says: "The teleological and mechanical views of nature are not necessarily exclusive. The teleologist can always defy the evolutionist to disprove that the primordial molecular arrangement was not intended to evolve the phenomena of the universe." Evolution, in short, by disclosing to us the marvellous power and accuracy of natural law, compels us more emphatically than ever to refer all law to a supreme, originating intelligence.
