Sec. 44. To this question, then, let us next address ourselves. From the theistic pleading which we have just heard, it is abundantly manifest that the formal conditions of a metaphysical teleology are present: the question now before us is as to whether or not any actual evidence exists in favour of such a theory. In order to discuss this question, let us begin by allowing the theist to continue his pleading. 'You have shown me,' he may say, 'that a scientific or demonstrable system of teleology is no longer possible, and, therefore, as I have already conceded, I must take my stand on a metaphysical or non-demonstrable system. But I reflect that the latter term is a loose one, seeing that it embraces all possible degrees of evidence short of actual proof. The question, therefore, I conceive to be, What amount of evidence is there in favour of this metaphysical system of teleology? And this question I answer by the following considerations:--As general laws separately have all been shown to be the necessary outcome of the primary data of science, it certainly follows that general laws collectively must be the same--_i.e._, that the whole system of general laws must be, so far as the lights of our science can penetrate, the necessary outcome of the persistence of force and the indestructibility of matter. But you have also dearly shown me that these lights are of the feeblest conceivable character when they are brought to illuminate the final mystery of things. I therefore feel at liberty to assert, that if there is any one principle to be observed in the collective operation of general laws which cannot conceivably be explained by any cause other than that of intelligent guidance, I am still free to fall back on such a principle and to maintain--Although the collective operation of general laws follows as a necessary consequence from the primary data of science, this one principle which pervades their united action, and which cannot be conceivably explained by any hypothesis other than that of intelligent guidance, is a principle which still remains to be accounted for; and as it cannot conceivably be accounted for on grounds of physical science, I may legitimately account for it on grounds of metaphysical teleology. Now I cannot open my eyes without perceiving such a principle everywhere characterising the collective operation of general laws. Universally I behold in nature, order, beauty, harmony,--that is, a perfect _correlation_ among general laws. But this ubiquitous correlation among general laws, considered as the cause of cosmic harmony, itself requires some explanatory cause such as the persistence of force and the indestructibility of matter cannot conceivably be made to supply. For unless we postulate some one integrating cause, the greater the number of general laws in nature, the less likelihood is there of such laws being so correlated as to produce harmony by their combined action. And forasmuch as the only cause that I am
