These two principles, as they exist in the world, are not antagonistic, but reciprocal. Home is the center from which men go forth to business; and business is the field from which they go home with the spoil. Home is the charm and stimulus of business; and business provides material for the comfort and beauty of home. This is the present practical relation between Communism and Joint-stockism every-where. And these two principles, thus working together, have had a wonderful expansion in modern times. Every body knows what progress has been made in Joint-stockism, from the old-fashioned simple partnership, to the thousands of corporations, small and great, that now do the work of the world. But Communism has had similar progress, from the little family circle, to the thousands of benevolent institutions that are now striving to make a home of the world. Every hospital and free school and public library that is comforting and civilizing mankind, is an extension of the free, loving element, that is the charm of home. And it is becoming more and more the fashion for men to spend the best part of their lives in accumulating millions by Joint-stockism, and at last lay their treasures at the feet of Communism, by endowing great public institutions of mercy or education. As these two principles are thus expanding side by side, the question arises, Which on the whole is prevailing and destined to prevail? and that means, which is primary in the order of truth, and which is secondary? The two great socialistic inventors seem to have taken opposite sides on this question. Owen believed that the grand advance which the world is about to make, will be into Communism. Fourier as confidently believed that civilization will ripen into universal Joint-stockism. In all cases of reciprocal dualism, there is manifestly a tendency to mutual absorption, coalescence and unity. Where shall we end? in Owenism or Fourierism? Or will a combination of both keep its place in the world hereafter, as it has done hitherto? and if so which will be primary and which secondary, and how will they be harmonized? We do not propose to answer these questions, but only to help the study of them, as we proceed with our history.
