"I performed the task of collecting the materials which form this volume, because I thought I was doing good. At one time, sanguine in anticipating brilliant results from Communism, I imagined mankind better than they are, and that they would speedily practise those principles which I considered so true. But the experience of years is now upon me; I have mingled with 'the world,' seen _stern reality_, and now am anxious to do as much as in me lies, to make known to the many thousands who look for a 'better state' than this on earth as well as in heaven, the amount (as it were at a glance) of the labors which have been and are now being performed in this country to realize that 'better state'. It may help to waken dreamers, to guide lost wanderers, to convince skeptics, to re-assure the hopeful; it may serve the uses of Statesmen and Philosophers, and interest the general reader; but it is most desirable that it should increase the charity of all those who may please to examine it, when they see that it was for Humanity, in nearly all instances, that these things were done. "Of necessity the work is imperfect, because of the difficulty in obtaining information on such subjects; but the attempt, whatever may be its result, should not be put off, since there is reason to believe that if not now collected, many particulars of the various movements would be forever lost. "It remains for a future historian to continue the labor which I have thus superficially commenced; for the day has not yet arrived when it can be said that Communism or Association has ceased to exist; and it is possible yet, in the progress of things, that man will endeavor to cure his social diseases by some such means; and a future history may contain the results of more important experiments than have ever yet been attempted. "I here return my thanks to the fearless, confiding, and disinterested friends, who so freely shared with me what little they possessed, to assist in the completion of this work. I name them not, but rejoice in their assistance. A.J. MACDONALD. "_New York City, 1854._" The tone of this preface indicates that Macdonald was discouraged. The effect of his book, if he had lived to publish it, would have been to aggravate the re-action against Socialism which followed the collapse of Fourierism. We hope to make a better use of his materials.
