It is thus that we are led to the fundamental doctrine of Theism, to belief in an intelligent First Cause, according to whose design the universe has been fashioned; a cause which must have all that is found in the universe or any part of it, including man, and more--for it has of itself what all else derives from it--whose purposes necessarily transcend our mental grasp--but whose modes of thought are reflected in our own, by which they can in some measure be followed through a study of their results. If such a belief, so grounded, be unscientific, as is constantly assumed, there must be good arguments to the contrary. It should be demonstrable, either that Science has shown such a line of reasoning to be unsound, or that she has discovered within her own domain something which, at least conceivably, can do the work thus attributed to Intelligence--in which case the much-quoted dictum of Lord Kelvin will be in point,--that if a probable solution of any problem can be found which is consistent with the ordinary course of Nature, we must not go beyond Nature in search of one. If, on the other hand, the above line of reasoning cannot be invalidated, and if scientific methods can discover nothing competent to effect what has undoubtedly been effected, it is not easy to see how it can be unscientific to proceed by inference to what is confessedly beyond the scope of observation and experiment. That "Teleology," or the doctrine of Final Causality,[136] is unworthy of serious consideration, is without doubt a common assumption, and some writers seem to think that an argument is sufficiently discredited if it be styled "teleological." Yet this rather formidable term represents no more than the belief that the infinite adaptations of means to results observed in Nature are the effect of purpose, not of chance. And if we eliminate purpose, what is there left to furnish an explanation, beyond the indubitable fact that such adaptations have always been found in organic nature, and that we have learnt confidently to anticipate that they will appear generation after generation according to the "law of heredity"? But this obviously only tells us that they have been produced and are likewise transmitted, and throws no light whatever on the cause of the marvellous processes to which their production and their transmission are due. If we have any rational grounds for expecting that such processes will continue to occur, it cannot be merely that they have occurred before, but we instinctively infer that the cause to which they are ultimately due continues to operate. We are thus as far as ever from an answer to the question, What is that cause?
