Our next witness is Horace Greely, Editor of the Tribune, and Napoleon of the Press. His first distinction was won by his espousing and elaborately propagating the Social Philosophy of Charles Casimir Fourier. This he did, some twenty years since, in a long controversy with the Courier & Enquirer: the latter paper sustaining the conservative side. The correspondence was afterwards published in book form, and we regret that we have not been able to possess ourselves of a copy. The whole edition, we learn, was burnt at the Harpers. Consigned by Providence, not by a human Censor, to the flames. Should we misrepresent our witness, it will be because we have tried in vain to get this book. We think he was the first, in America, to assert, and maintain by arguments and proofs, the inadequacy and injustice of the whole social and governmental organization at the North. He, not ourselves, is the American author of the theory of the Failure of Free Society. His remedies, though not as radical and scientific as those of Proudhon and Mr. Andrews, did very well for a beginning. He, we think, proposed at once to coop mankind up in Phalansteries, where, in a few generations, all the distinctions of separate property, and of separate wives and children, would be obliterated and lost, and society would gradually and gently be fused and crystalized into a system of pure and perfect Communism. The Tribune has to minister to a variety of tastes, all agreeing in their destructive tendencies, but differing widely as to the manner in which they shall attain their conclusions; hence, it is hard to deduce any well defined system of philosophy from its columns. Mr. Andrews intimates, that our witness is no philosopher at all. Be it so. Yet all must admit that no man of the age has the organ or faculty of Destructiveness so fully developed. The Tribune has been, from the time of the controversy of which we have spoken, to the present day, the great Organ of Socialism, of Free Love, and of all the other isms which propose to overthrow and rebuild society and government, or to dispense with them altogether. Steadily pursuing this destructive course, the Tribune has for years become the most popular paper in the North, and, 'tis said, has more readers in Europe and America than any paper in the world; and yet its only peculiar thought, its whole intellectual, moral, social and political stock in trade, consists of the one idea, variously expressed, illustrated and enforced, "The Failure of Free Society;" or, as Carlyle phrases it, "We must have a new world, if we are to have any world at all."
