[It is a fallacy] that capital is produced (and reproduced in any sort of cycle) by labour or “primary factors” in any sense. This is palpably absurd; “labour,” “capital instruments,” and “land” are in the first place categories of no homogeneity within themselves and of extensive overlapping, and in the second place, however productive agencies may be classified, it is evident that each is produced and continuously reproduced (when at all) by the co-operation of all, including itself.
