My second selection is from the "Principia" of Sir Isaac Newton, a work which, by the general consent of the scientific world, is the greatest contribution ever made to science. Sir Isaac Newton was a Physicist rather than a Metaphysician; he will therefore represent to us the conception of God entertained by the scientific Theist. At the close of this his great work he writes: "The true God is a living, intelligent, powerful Being, and, from His other perfections, it follows that He is Supreme, or most perfect. He is eternal and infinite, omnipotent and omniscient; that is, His duration reaches from eternity to eternity, His presence from infinity to infinity. He governs all things, and knows all things that are or can be done. He is not eternity and infinity, but eternal and infinite. He is not duration or space, but He endures and is present. He endures forever, and He is every where present; and by existing always and every where, He constitutes [or causes] duration and space. Since every particle of space is _always_, and every indivisible moment of duration is _every where_, certainly the Maker and Lord of all things can not be _never_ and _nowhere_.... God is the same God, always and every where. He is omnipresent, not _virtually_ [potentially] only, but also substantially; for virtue can not subsist without substance. In Him all things are contained and moved, yet neither affects the other. God suffers nothing from the motion of bodies; bodies find no resistance from the omnipresence of God. It is allowed by all that the Supreme God exists necessarily; and by the same necessity exists _always_ and _every where_.... We know Him only by His most wise and excellent contrivances of things and final causes; we admire Him for His perfections; but we reverence and adore Him on account of His dominion. A God without dominion, providence, and final causes is nothing else but Fate and Nature. Blind mechanical necessity, which is certainly the same always and every where, could produce no variety of things. All that diversity of natural things which we find suited to different times and places could arise from nothing but the _ideas_ and _will_ of a Being necessarily existing." My last selection is from the "Grammar of Assent," by John Henry Newman, formerly a Protestant, now a Catholic divine. Prior to his change of theological position he published a remarkable work "On the Development of Christian Doctrine in Aid of a Grammar of Assent," the design of which is to exhibit the influence of philosophic thought upon the evolution of Christian doctrine, and to bring it into harmony with the theories of Cosmical, Physiological, and Historical development, which seem for the present to be in the ascendant. For this reason I choose to employ his words, as setting forth the conception of God which is generally entertained by thoughtful men. At page ninety-seven of his last work, "The Grammar of Assent," I read:
