LONDON MACMILLAN AND CO., LIMITED NEW YORK: THE MACMILLAN COMPANY 1905 _First published elsewhere_ _New Edition 1886. Reprinted 1891, 1897, 1905_ PREFACE. The present work closes a series of studies on the literary preparation for the French Revolution. It differs from the companion volumes on Voltaire and Rousseau, in being much more fully descriptive. In the case of those two famous writers, every educated reader knows more or less of their performances. Of Diderot and his circle, such knowledge cannot be taken for granted, and I have therefore thought it best to occupy a considerable space, which I hope that those who do me the honour to read these pages will not find excessive, with what is little more than transcript or analysis. Such a method will at least enable the reader to see what those ideas really were, which the social and economic condition of France on the eve of the convulsion made so welcome to men. The shortcomings of the encyclopaedic group are obvious enough. They have lately been emphasised in the ingenious and one-sided exaggerations of that brilliant man of letters, Mr. Taine. The social significance and the positive quality of much of their writing is more easily missed, and this side of their work it has been one of my principal objects, alike in the case of Voltaire, of Rousseau, and of Diderot, to bring into the prominence that it deserves in the history of opinion. The edition of Diderot's works to which the references are made, is that in twenty volumes by the late Mr. Assezat and Mr. Maurice Tourneux. The only other serious book on Diderot with which I am acquainted is Rosenkranz's valuable _Diderot's Leben_, published in 1866, and abounding in full and patient knowledge. Of the numerous criticisms on Diderot by Raumer, Arndt, Hettner, Damiron, Bersot, and above all by Mr. Carlyle, I need not make more particular mention. _May, 1878._ NOTE. Since the following pages were printed, an American correspondent writes to me with reference to the dialogue between Franklin and Raynal, mentioned on page 218, Vol. II.:--"I have now before me Volume IV. of the _American Law Journal_, printed at Philadelphia in the year 1813, and at page 458 find in full, 'The Speech of Miss Polly Baker, delivered before a court of judicature in _Connecticut_, where she was prosecuted.'" Raynal, therefore, would have been right if instead of Massachusetts he had said Connecticut; and either Franklin told an untruth, or else Silas Deane. _September, 1878._ CONTENTS OF VOL. I.
