There is nothing so especially exalted therefore in the Natural Laws in themselves as to make one anxious to find them blood relations of the Spiritual. It is not only because these Laws are on the ground, more accessible therefore to us who are but groundlings; not only, as the "Unseen Universe" points out in another connection, "because they are at the bottom of the list--are in fact the simplest and lowest--that they are capable of being most readily grasped by the finite intelligences of the universe."[26] But their true significance lies in the fact that they are on the list at all, and especially in that the list is the same list. Their dignity is not as Natural Laws, but as Spiritual Laws, Laws which, as already said, at one end are dealing with Matter, and at the other with Spirit. "The physical properties of matter form the alphabet which is put into our hands by God, the study of which, if properly conducted, will enable us more perfectly to read that great book which we call the 'Universe.'"[27] But, over and above this, the Natural Laws will enable us to read that great duplicate which we call the "Unseen Universe," and to think and live in fuller harmony with it. After all, the true greatness of Law lies in its vision of the Unseen. Law in the visible is the Invisible in the visible. And to speak of Laws as Natural is to define them in their application to a part of the universe, the sense-part, whereas a wider survey would lead us to regard all Law as essentially Spiritual. To magnify the Laws of Nature, as Laws of this small world of ours, is to take a provincial view of the universe. Law is great not because the phenomenal world is great, but because these vanishing lines are the avenues into the eternal Order. "It is less reverent to regard the universe as an illimitable avenue which leads up to God, than to look upon it as a limited area bounded by an impenetrable wall, which, if we could only pierce it would admit us at once into the presence of the Eternal?"[28] Indeed the authors of the "Unseen Universe" demur even to the expression _material universe_, since, as they tell us "Matter is (though it may seem paradoxical to say so) the less important half of the material of the physical universe."[29] And even Mr. Huxley, though in a different sense, assures us, with Descartes, "that we know more of mind than we do of body; that the immaterial world is a firmer reality than the material."[30]
