utopianism, he is precluded from all possibility of scientific progress. From 1842 until his death he turned in the same circle, reproduced the same ideas, already expressed or indicated in his preceding works, found himself misunderstood, found himself pillaged, when he had nothing of which to be robbed, and at last refused to accept the evidence that at bottom he had discovered nothing which had not already been established long before him.
It is scarcely necessary to remark that in this work the language is not identical with that of "Capital." In this work Marx still speaks of labor as a commodity, and of its purchase and sale, instead of labor power.
As appendices we have added to this work: 1st, a passage from Marx's work, "Critique de l'Economie Politique," Berlin, 1859, with reference to the first labor-notes utopia of John Gray; and 2nd, the discourse of Marx on "Free Trade" delivered in French at Brussels in 1847, which belongs to the same period of the author's development as the "Misère."
