The Reign of Law has gradually crept into every department of Nature, transforming knowledge everywhere into Science. The process goes on, and Nature slowly appears to us as one great unity, until the borders of the Spiritual World are reached. There the Law of Continuity ceases, and the harmony breaks down. And men who have learned their elementary lessons truly from the alphabet of the lower Laws, going on to seek a higher knowledge, are suddenly confronted with the Great Exception. Even those who have examined most carefully the relations of the Natural and the Spiritual, seem to have committed themselves deliberately to a final separation in matters of Law. It is a surprise to find such a writer as Horace Bushnell, for instance, describing the Spiritual World as "another system of nature incommunicably separate from ours," and further defining it thus: "God has, in fact, erected another and higher system, that of spiritual being and government for which nature exists; a system not under the law of cause and effect, but ruled and marshaled under other kinds of laws."[9] Few men have shown more insight than Bushnell in illustrating Spiritual truth from the Natural World; but he has not only failed to perceive the analogy with regard to Law, but emphatically denies it. In the recent literature of this whole region there nowhere seems any advance upon the position of "Nature and the Supernatural." All are agreed in speaking of Nature _and_ the Supernatural. Nature _in_ the Supernatural, so far as Laws are concerned, is still an unknown truth. "The Scientific Basis of Faith" is a suggestive title. The accomplished author announces that the object of his investigation is to show that "the world of nature and mind, as made known by science, constitute a basis and a preparation for that highest moral and spiritual life of man, which is evoked by the self-revelation of God."[10] On the whole, Mr. Murphy seems to be more philosophical and more profound in his view of the relation of science and religion than any writer of modern times. His conception of religion is broad and lofty, his acquaintance with science adequate.
