Whilst the greatest effort has been made to ensure the quality of this text, due to the historical nature of this content, in some rare cases there may be minor issues with legibility. I am not unmindful that there have been hundreds, perhaps thousands of author-heroes and heroines. Bacon, Locke, Lu ther, Voltaire, * Fourier, and Robert Owen were prominently of the former, and Mary Wollstonecraft and Frances Wright were decidedly among the latter. But it appears to me, that none of their writings have been quite such text-books of revolution, as those of Rousseau and Paine were, and those of Comte now are.
