In treating, again, of the Critical or destructive system of Metaphysics, and of the Positive or reconstructive system of the New Philosophy, he adduces no evidence to show that _the same element_ is negatived by the one and restored by the other; on the contrary, were his statement true in all respects, it would only serve to prove that the Theological element, which is slowly dissipated by Metaphysics, is formally and finally abjured by Positivism. He assumes and asserts, on very insufficient grounds, that there is a real, radical, and necessary contrariety between the facts and laws of Science and the first principles of Theology, whether natural or revealed; and he anticipates, therefore, that in proportion as Science advances, Theology must recede, and ultimately quit the field. He ought to have known that there are minds in every part of Europe as thoroughly scientific as his own, and as deeply imbued with the spirit of modern Inductive Philosophy, who, so far from seeing any discordance between the results of scientific inquiry and the fundamental truths of Theology, are in the habit of appealing to the former in proof or illustration of the latter; and who, the further they advance in the study of the works of Nature, are only the more confirmed in their belief of a Creative Intelligence and a Governing Power. It may be that, in his own immediate circle at Paris, there is a tendency towards Atheism; but, assuredly, no such tendency exists in the highest and most scientific minds of modern Europe. The faith of Bacon, Newton, and Boyle, of Descartes, Leibnitz, and Pascal, in regard to the first principles of Theology, is still the prevailing creed of the Sedgwicks, the Whewells, the Herschells, and the Brewsters of the present day.
