To begin with, even the distinct title of "Atheist" may mean any number of things for any number of persons. Ill-informed and even some well-informed people commonly describe an Atheist as one who says "There is no God," and that "Things happen by chance." To say to such persons--as has been said a thousand times--that for an Atheist both phrases are meaningless, seems to give no help: we must begin at the beginning, and show how the dispute arose. And it is useful to keep in view that Bradlaugh's Atheism, in the evolution of English Freethought, is only a generation removed from the Deism of Thomas Paine, which is much the same as the Deism of Voltaire. Deism or Theism is to-day reckoned a quite "religious" frame of mind; but it was the frame of mind of men who in their day were hated and vilified by Christians as much as Bradlaugh in his. Explicit Atheism is only in our own day become at all a common opinion. The men so described in former ages, so far as we know (if we set aside the remarkable developments of the Italian Renaissance), have nearly always been Deists or Pantheists, of whom the latter of course tend logically to coalesce with Atheism, but who have in their own names alike professed to repudiate Atheism. Thus Hobbes and Spinoza, who last century were constantly called Atheists by Christians, always professed to have a God-idea; and the Freethinkers who showed head in England in the first half of the eighteenth century were all professing Deists. Systematic Atheism began to arise among the more penetrating or more trained thinkers of the latter half of the century. Thus Hume, after professing Deism throughout his life, left for posthumous publication his "Dialogues concerning Natural Religion," which amount to the surrender of all forms of Theism. Of Voltaire in his latter years, when he strongly attacked the Atheism of Holbach, it was said by the more high-flying talkers of the Paris drawing-rooms: "Why, he is a bigot; he is a Deist." But even Voltaire, as Mr Morley has shown, was somewhat less of a Deist after the earthquake of Lisbon; and "Candide" is not a good Theistic tract.[70] Diderot, again, reached explicit Atheism; and his friend Holbach wrote, in the "Système de la Nature," the first systematic and straightforward Atheistic treatise of modern times.[71] In England the movement was less rapid. Bolingbroke went pretty far towards a Lucretian or Agnostic Theism; and the upper-class Deism which on his lines held out against the opportunist orthodoxy of Butler, necessarily tended to make its Deity a very remote and inaccessible Power. But Freethought, to get any hold on the general mind in the thickening populations of the latter half of last century and the first half of this, had to begin again, and more effectively, on the lines of the first Deists. The incredibility of the sacred books had to be made clear before more abstract issues could be settled. In this task Voltaire, the pupil of the English Deists, was
