In summing up the results to which an examination of the facts of consciousness conducted him, Mr. Mansel utters the following psychological error: "But a limit is necessarily conceived as a relation between something within and something without itself; and the consciousness of a limit of thought implies, though it does not directly present to us, the existence of something of which we do not and cannot think." Not so; for a limit may be seen to be wholly within the being to whom it belongs, and so _not_ to be "a relation between something within and something without itself." This is precisely the case with the Deity. All relations and limits spring from within him, and there is nothing "without" to establish the relation claimed. This absence of all limit from without is rudely expressed in such common phrases as this: "It must be so in the _nature of things_." This "nature of things" is, in philosophical language, the system of _a priori_ laws of the Universe, and these are necessary ideas in the Divine Reason. It appears, then, that what must be in the nature of things, finds its limits wholly within, and its relations established by the Deity. With these remarks the author would close his criticism upon Mr. Mansel's book. We start from entirely different bases, and these two systems logically follow from their foundations. If Sir William Hamilton is right in his psychology, his follower is unquestionably right in his deductions. But if that psychology is partial, if besides the Understanding there is the Reason, if above the judgment stands the intuition, giving the final standard by which to measure that judgment, then is the philosophical system of the Divine utterly fallacious. The establishment of the validity of the Pure Reason is the annihilation of "the Philosophy of the Unconditioned." On the ground which the author has adopted, it is seen that "God is a spirit," infinite, absolute, self-conscious, personal; and a consistent interpretation of these terms has been given. We have found that certain objects may be seen as out of all relation, plurality, difference, or likeness. Consciousness and personality have also been found to involve no limit, in the proper sense of that term. On the contrary, the one was ascertained to be the light in which any or all objects might be seen under conditions of Time, or at once; and that this seeing was according to the capacity with which the being was endowed, and was not determined by any peculiarity of the consciousness; while the other appeared to be the highest possible form of existence, and that also in which God had revealed himself. From such a ground it is possible to go forward and construct a Rational Theology which shall verify by Reason the teachings of the Bible. REVIEW OF MR. HERBERT SPENCER'S "FIRST PRINCIPLES."
