Thus, upon the whole, it may be said, without danger of reasonable dispute, that as the argument from Order has hitherto derived its immense weight entirely from the fact that Intelligence appeared to be the one and only cause sufficient to produce the observed integration of the cosmos, this immense weight has now been completely counterpoised by the demonstration that other causes of a strictly physical kind must have been instrumental, if not themselves alone sufficient, to produce this integration, So that, just as in the case of Astronomy the demonstration of the one natural principle of gravity was sufficient to classify under one physical explanation several observed facts which many persons had previously attributed to supernatural causes; and just as in the more complex science of Geology the demonstration of the one principle of uniformitarianism was sufficient to explain, without the aid of supernaturalism, a still greater number of facts; and, lastly, just as in the case of the still more complex science of Biology the demonstration of the one principle of natural selection was sufficient to marshal under one scientific, or natural, hypothesis an almost incalculable number of facts which were previously explained by the metaphysical hypothesis of supernatural design; so in the science which includes all other sciences, and which we may term the science of Cosmology, I assert with confidence that in the one principle of the persistence of force we have a demonstrably harmonising principle, whereby all the facts within our experience admit of being collocated under one natural explanation, without there being the smallest reason to attribute these facts to any supernatural cause. But perhaps the immense change which these considerations must logically be regarded as having produced in the speculative standing of the argument from teleology will be better appreciated if I continue to quote from Professor Flint's very forcible and thoroughly logical exposition of the previous standing of this argument. He says:-- "To ascribe the origination of order to _law_ is a manifest evasion of the real problem. Law is order. Law is the very thing to be explained. The question is--Has law a reason, or is it without a reason? The unperverted human mind cannot believe it to be without a reason." I do not know where a more terse and accurate statement of the case could be found; and to my mind the question so lucidly put admits of the direct answer--Law clearly has a reason of a purely physical kind. And therefore I submit that the following quotation which Professor Flint makes from Professor Jevons, logical as it was when written, must now be regarded as embodying an argument which is obsolete.
