The overthrow of the St. Simonian School at Paris was the point, as is well known, from which the prevalence of Fourierism commenced. With the failure of its external success, the whole of the St. Simonian School came to an end, both what was true in it and what was false. The person, who was the first, and that after a period of nearly twenty years, to take a lively interest in the ideas of Charles Fourier, was Just Muiron, who in the year 1814 attempted to apply them to the “Communal Comptoir.” He was sincere and devoted, but did not possess the qualities to promulgate and defend the new system of society. It could not succeed, unless a man was found, combining profound convictions with ardent zeal, and the gift of eloquence, demanded by new ideas in order to secure the attention of the public to the question proposed. Such a man was Victor Considerant. His education in Polytechnic school had accustomed him not merely to follow a rigid calculation but to appropriate its results as actual truths; the demonstration in figures for Fourier’s statements of the subversion of the present social institutions as regards the total production was not to be set aside. It was then but a single step to the idea of an Agricultural Association leading to the practical side of Fourier’s theory. Considerant was convinced: he formed personal relations with Fourier himself; ideas were exchanged; and the chief points of the school, then in its infancy, were established. After Jules Lechevalier (now in exile in London) and Abel Transon were brought into the School, the former lecturing upon its principles in Paris and the other promulgating them by his pen, Considerant repaired to Metz, where he delivered a course on the theory of Fourier, and subsequently became one of the most active contributors to the _Phalanstère_ or _Réforme Industrielle_, which appeared at the beginning of 1832.
