Accordingly, as has already been urged, in regard of this question we are precisely where men have always been,--dependent upon arguments such as satisfied philosophers like Cicero, who declared that when we regard the starry heavens the existence of a Deity of surpassing intelligence must appear no less obvious than that of the sun in the sky.[146] That scientific enlightenment is not incompatible with such reasoning, we have sufficient evidence in the fact that amongst those whose conclusions are wholly in accord with Cicero's, men are to be found standing in the very front rank of Science. Like the Roman orator, Sir Isaac Newton declared that the existence of a Being endowed with intelligence and wisdom is a necessary inference from a study of celestial mechanics, and that to treat of God is therefore a part of Natural Philosophy.[147] We assume, as absolutely self-evident [say Professors Stewart and Tait][148] the existence of a Deity, who is the Creator and Upholder of all things. When we contemplate the phenomena of vision, [says Sir G. G. Stokes,][149] it seems difficult to understand how we can fail to be impressed with the evidence of design thus imparted to us. But design is altogether unmeaning without a designing mind. The study then of the phenomena of nature leads us to the contemplation of a Being from whom proceeded the orderly arrangement of natural things that we behold. Lord Kelvin's recent declaration is even more vigorous.[150] I cannot say that with regard to the origin of life Science neither affirms nor denies creative power. Science positively affirms creating and directive power, which she compels us to accept as an article of belief. Thirty years earlier Clerk-Maxwell in concluding his famous lecture before the British Association[151] thus spoke concerning Molecules: They continue this day as they were created, perfect in number and measure and weight, and from the ineffaceable characters impressed on them we may learn that those aspirations after accuracy in measurement, truth in statement, and justice in action, which we reckon among our noblest attributes as men, are ours because they are essential constituents of the image of Him who in the beginning created, not only the heaven and the earth, but the materials of which heaven and earth consist.
