From such principles atheism naturally proceeded. Atheism not of opinion merely, but of sentiment and feeling; for at that time "the potencies" of matter impressed no such awe upon the mind as they have done since; the "mystery of matter" was unfelt; physiology was an unexplored region; the materialist simply denied spirit, putting a blank where believers in religion had been used to find a soul; and had no alternative but to run sensationalism into sensualism, and to give the senses the flavor of the ground. With us the sensational philosophy has become refined into a philosophy of experience, and the materialist finds himself in a region where to distinguish between matter and spirit is difficult, to say the least. But a hundred years ago matter was clod, and the passion it engendered smelt of the charnel-house. The morbid insanities of the revolution, the orgies in which blood and wine ran together, the savage glee, the delirium that ensued when the uncertainty of life acting on the impulse to enjoy life while it lasted, made men ferocious in clutching at immediate pleasure, attest the consequences that ensued from such frank adoption of the sensational philosophy as was practised among the French. Locke was a man of piety, which even his warmest apologists will hardly claim for Voltaire. The English mind, grave and thoughtful, trained by religious institutions in religious beliefs, was less inclined than the French to drive speculative theories to extreme conclusions. The philosophy of sensationalism culminated, not in the French Revolution, as has been vulgarly asserted, but in the unbelief and sensual extravagance that marked one phase of it. In this there was nothing original; there was no originality in the reaction that followed, and gave to modern philosophy in France its spiritual character. Laromiguiére, educated in the school of Condillac, improved on the suggestion that Condillac had given, and deepened into a chasm the scratch he had made to indicate a distinction between the results of sensation and the faculties of the mind. In his analysis of the mental constitution he came upon two facts that denoted an original activity in advance of sensation--namely, _attention_ and _desire_: the former the root of the intellectual, the latter of the moral powers; both at last resolvable into one principle--attention. This discovery met with wide and cordial welcome, the popularity of Laromiguiére's lectures, delivered in 1811, 1812, 1813, revealing the fact that thoughtful people were prepared for a new metaphysical departure.
