understanding of matter is the analysis of mind, through which all matter _is_ and is _constructed_. Without this first step, all other steps are simply a stumble in the dark--the blind-man's buff of children. Or we may say, with a little more dignity, perhaps, that every material law of the cosmos is subject to "The Law of Scientific Idealism." Now scientific idealism, pursued to the end, merges in absolute idealism. The source and substance of the universe is Intelligent Spirit; or, as the Bible and its Theologians say, this is the All-In-All. For fifty years--from the publication of Kant's _Critique_ in 1781, along through Fichte, and Schelling, to the death of Hegel in 1831--the vast illumination of thought that has been summed up as "German Transcendentalism" strove to unify natural theology and practical science in "Absolute Idealism." It will yet be seen that the work was done, however ill-comprehended. The good old Kant still had his whole head with him when he said, in 1787, "the danger, in this case, is not that of being refuted, but of being misunderstood." The Comtes, the Hamiltons, the Mills and Spencers--with no end, too, of their German brothers--are illustrious examples in proof of Kant's remark, however greatly they may be respected within the limits of their own work. Once and for good, the history of philosophy, when understood, and the history of science, when understood, have joined in the proof that the principle of all life--we may say God if we like--is Spirit Principle.
