We get but a very imperfect idea of the Owen and Fourier movements from the short-lived experiments whose remains are before us in Macdonald's collections. In the first place Macdonald, faithful as he was, did not discover all the experiments that were made during those movements. We remember some that are not named in his manuscripts. And in the next place the numbers engaged in the practical attempts were very small, in comparison with the masses that entered into the enthusiasm of the general movements and abandoned themselves to the idea of an impending social revolution. The eight thousand and six hundred that we found by averaging Macdonald's list, might probably be doubled to represent the census of the obscure unknown attempts, and then multiplied by ten to cover the outside multitudes that were converted to Socialism in the course of the Owen and Fourier revivals. Owen in 1824 stirred the very life of the nation with his appeals to Kings and Congresses, and his vast experiments at New Harmony. Think of his family of nine hundred members on a farm of thirty thousand acres! A magnificent beginning, that thrilled the world! The general movement was proportionate to this beginning; and though this great Community and all the little ones that followed it failed and disappeared in a few years, the movement did not cease. Owen and his followers--especially his son Robert Dale Owen and Frances Wright--continued to agitate the country with newspapers, public lectures, and "Fanny Wright societies," till their ideas actually got foot-hold and influence in the great Democratic party. The special enthusiasm for practical attempts at Association culminated in 1826, and afterwards subsided; but the excitement about Owen's ideas, which was really the Owen movement, reached its height after 1830; and the embers of it are in the heart of the nation to this day. On the other hand, Fourier (by proxy) started another national excitement in 1842. With young Brisbane for its cosmopolitan apostle, and a national newspaper, such as the _New York Tribune_ was, for its organ, this movement, like Owen's, could not be otherwise than national in its dimensions. We shall have occasion hereafter to show how vast and deep it was, and how poorly it is represented by the Phalanxes that figure in Macdonald's memoirs. Meanwhile let the reader consider that several of the men who were leaders in this excitement, were also leaders then and afterwards in the old Whig party; and he will have reason to conclude that Socialism, in its duplex form of Owenism and Fourierism, has touched and modified both of the party-sections and all departments of the national life.
