Just as German theoretical socialism will never forget that it rests on the shoulders of Saint Simon, Fourier and Owen, three men who, in spite of all their fantastic notions and utopianism, have their place among the most eminent thinkers of all time, and whose genius anticipated innumerable truths the correctness of which can now be scientifically proved, so the practical German labor movement must never forget that it has developed on the shoulders of the English and French movements, that it was able simply to utilize their dearly bought experience, and could now avoid their mistakes which in their time were mostly unavoidable.
