Condorcet had suggested that the value of history lies in affording data for foreseeing the future. Saint-Simon raised this suggestion to a dogma. But prevision was impossible on Condorcet's unscientific method. In order to foretell, the law of the movement must be discovered, and Condorcet had not found or even sought a law. The eighteenth century thinkers had left Progress a mere hypothesis based on a very insufficient induction; their successors sought to lift it to the rank of a scientific hypothesis, by discovering a social law as valid as the physical law of gravitation. This was the object both of Saint-Simon and of Comte. The "law" which Saint-Simon educed from history was that epochs of organisation or construction, and epochs of criticism or revolution, succeed each other alternately. The medieval period was a time of organisation, and was followed by a critical, revolutionary period, which has now come to an end and must be succeeded by another epoch of organisation. Having discovered the clew to the process, Saint-Simon is able to predict. As our knowledge of the universe has reached or is reaching a stage which is no longer conjectural but POSITIVE in all departments, society will be transformed accordingly; a new PHYSICIST religion will supersede Christianity and Deism; men of science will play the role of organisers which the clergy played in the Middle Ages. As the goal of the development is social happiness, and as the working classes form the majority, the first step towards the goal will be the amelioration of the lot of the working classes. This will be the principal problem of government in reorganising society, and Saint-Simon's solution of the problem was socialism. He rejected the watchwords of liberalism--democracy, liberty, and equality--with as much disdain as De Maistre and the reactionaries. The announcement of a future age of gold, which I quoted above, is taken from a pamphlet which he issued, in conjunction with his secretary, Augustin Thierry the historian, after the fall of Napoleon. [Footnote: De la reorganisation de la societe europeenne, p. 111 (1814).] In it he revived the idea of the Abbe de Saint-Pierre for the abolition of war, and proposed a new organisation of Europe more ambitious and Utopian than the Abbe's league of states. At this moment he saw in parliamentary government, which the restored Bourbons were establishing in France, a sovran remedy for political disorder, and he imagined that if this political system were introduced in all the states of Europe a long step would have been taken to the perpetuation of peace. If the old enemies France and England formed a close alliance there would be little difficulty in creating ultimately a European state like the American Commonwealth, with a parliamentary government supreme over the state governments. Here is the germ of the idea of a "parliament of man." 3.
