So we will assert our own old-fashioned notion boldly; and more: we will say, in spite of ridicule, that if such a God exists, final causes must exist also. That the whole universe must be one chain of final causes. That if there be a Supreme Reason, He must have a reason, and that a good reason, for every physical phenomenon. We will tell the modern scientific man--You are nervously afraid of the mention of final causes. You quote against them Bacon's saying, that they are barren virgins; that no physical fact was ever discovered or explained by them. You are right as far as regards yourselves; you have no business with final causes, because final causes are moral causes, and you are physical students only. We, the natural theologians, have business with them. Your duty is to find out the How of things; ours, to find out the Why. If you rejoin that we shall never find out the Why, unless we first learn something of the How, we shall not deny that. It may be most useful, I had almost said necessary, that the clergy should have some scientific training. It may be most useful, I sometimes dream of a day when it will be considered necessary, that every candidate for ordination should be required to have passed creditably in at least one branch of physical science, if it be only to teach him the method of sound scientific thought. But our having learnt the How, will not make it needless, much less impossible, for us to study the Why. It will merely make more clear to us the things of which we have to study the Why; and enable us to keep the How and the Why more religiously apart from each other. But if it be said: After all, there is no Why; the doctrine of evolution, by doing away with the theory of creation, does away with that of final causes--let us answer, boldly: Not in the least. We might accept all that Mr. Darwin, all that Professor Huxley, has so learnedly and so acutely written on physical science, and yet preserve our natural theology on exactly the same basis as that on which Butler and Paley left it. That we should have to develop it, I do not deny. That we should have to relinquish it, I do. Let me press this thought earnestly on you. I know that many wiser and better men than I have fears on this point. I cannot share in them.
