Note 880 — Chapter II · : STATE SOCIALISM

There has been no dispute concerning the French origin of Rodbertus’s ideas since the evidence was sifted by Menger in his Das Recht auf den vollen Arbeitsertrag (1st ed., 1886). But Menger only mentions two sources of inspiration, Proudhon and the Saint-Simonians. The text will sufficiently indicate his indebtedness to the Saint-Simonians, but we think that Sismondi might well have been substituted for Proudhon. The only Proudhonian doctrine that is discoverable in Rodbertus is the theory concerning the constitution of value. But in the second of the Soziale Briefe (Schriften, vol. ii, p. 46, note) he states definitely that the idea was not a borrowed one, and that he himself was the first to formulate it, although he omits to state in what connection. He may be referring to a passage in his Forderungen, where the idea is quite clearly expressed. Speaking of Ricardo’s theory of value, he says: “That theory comes to grief on a single issue, namely, in regarding a thing as existing when it only exists in the mind, and treating a thing as a reality when it only becomes real in the future.” (Schriften, vol. iii, p. 120.) It is clearly pointed out that the task of the future is to determine what value is. The Forderungen, where all the master ideas of Rodbertus may be studied, was published in 1837, nine years before the Contradictions économiques was published by Proudhon, who made his first reference to the question in that work.
