He took no part of any importance in the French Revolution, but amassed a little fortune by land speculation—not on his own account, however, as he said, but to facilitate his future projects. Accordingly, when he was nearly forty years of age he went through a varied course of study and experiment, in order to enlarge and clarify his view of things. One of these experiments was an unhappy marriage, which after a year’s duration was dissolved by the mutual consent of the parties. Another result of his experiments was that he found himself completely impoverished, and lived in penury for the remainder of his life. The first of his numerous writings, _Lettres d’un Habitant de Genève_, appeared in 1803; but his early works were mostly scientific and political. It was not till 1817 that he began, in a treatise entitled _L’Industrie_, to propound his socialistic views, which he further developed in _L’Organisateur_ (1819), _Du Système industrial_ (1821), _Catéchisme des Industriels_ (1823). The last and most important expression of his views is the _Nouveau Christianisme_ (1825). For many years before his death in 1825 Saint-Simon had been reduced to the greatest straits. He was obliged to accept a laborious post for a salary of £40 a year, to live on the generosity of a former valet, and finally to solicit a small pension from his family. In 1823 he attempted suicide in despair. It was not till very late in his career that he attached to himself a few ardent disciples. As a thinker Saint-Simon was entirely deficient in system, clearness, and consecutive strength. His writings are largely made up of a few ideas continually repeated. But his speculations are always ingenious and original; and he has unquestionably exercised great influence on modern thought, both as the historic founder of French socialism and as suggesting much of what was afterwards elaborated into Comtism. Apart from the details of his socialistic teaching, with which we need not concern ourselves, we find that the ideas of Saint-Simon with regard to the reconstruction of society are very simple. His opinions were conditioned by the French Revolution and by the feudal and military system still prevalent in France. In opposition to the destructive liberalism of the Revolution he insisted on the necessity of a new and positive reorganisation of society. So far was he from advocating social revolt that he appealed to Louis XVIII. to inaugurate the new order of things. In opposition, however, to the feudal and military system, the former aspect of which had been strengthened by the Restoration, he advocated an arrangement by which the industrial chiefs should control society. In place of the Mediæval Church, the spiritual direction of society should fall to the men of science. What Saint-Simon desired, therefore, was an industrialist State directed by modern science. The men who are best fitted to organise society for productive labour are entitled to bear rule in it.
