I am therefore sorry to see this absurd argument approvingly incorporated in Professor Flint's work. He says, "I believe that no reply to these words of Professor Clark Maxwell is possible from any one who holds the ordinary view of scientific men as to the ultimate constitution of matter. They must suppose every atom, every molecule, to be of such a nature, to be so related to others and to the universe generally, that things may be such as we see them to be; but this their fitness to be built up into the structure of the universe is a proof that they have been made fit, and since natural forces could not have acted on them while not yet existent, a supernatural power must have created them, and created them with a view to their manifold uses." Here the inference so confidently drawn would have been a weak one even were we not able to see that the doctrine of natural evolution probably applies to inorganic nature no less than to organic. For the inference is drawn from considerations of a character so transcendental and so remote from science, that unless we wish to be deceived by a merely verbal argument, we must feel that the possibilities of error in the inference are so numerous and indefinite, that the inference itself is well-nigh worthless as a basis of belief. But when we add that in Chapter IV. of the foregoing essay it has been shown to be within the legitimate scope of scientific reasoning to conclude that material atoms have been progressively evolved _pari passu_ with the natural laws of chemical combination, it is evident that any force which the present argument could ever have had must now be pronounced as neutralised. Natural causes have been shown, so far as scientific inference can extend, as not improbably sufficient to produce the observed effects; and therefore we are no longer free to invoke the hypothetical action of any supernatural cause.
