But the final touch is provided by the 'popular', 'new and inexpensive' edition of Puttkamer and Muehlbrecht (1899). Some of the quarrelling editors collaborated on it but still continue their disputes in the introductions. Wagner's former vol. ii has become vol. i in this edition, yet Wagner still refers to vol. ii in the introduction to vol. i. The first _Letter on Social Problems_ is placed in vol. iii, the second and third in vol. ii and the fourth in vol. i. The order of the _Letters on Social Problems_, of the _Controversies_, of the parts of _Towards the Understanding_ ..., chronological and logical sequence, the dates of publication and of writing are hopelessly mixed up, making a chaos more impenetrable than the stratification of the soil after repeated volcanic eruptions. 1837 is maintained as the date of Rodbertus' earliest MS., probably out of respect to Professor Wagner--and this in 1899, although Mehring's rectification had been made in 1894. If we compare this with Marx's literary heritage in Mehring's and Kautsky's edition, published by Dietz, we see how such apparently superficial matters but reflect deeper connections: one kind of care for the scientific heritage of the authority of the class-conscious proletariat, and quite another in which the official experts of the bourgeoisie squander the heritage of a man who, in their own self-interested legends, had been a first-rate genius. _Suum cuique_--had this not been the motto of Rodbertus? _SECTION TWO_ HISTORICAL EXPOSITION OF THE PROBLEM THIRD ROUND STRUVE-BULGAKOV-TUGAN BARANOVSKI _v._ VORONTSOV-NIKOLAYON _CHAPTER XVIII_ A NEW VERSION OF THE PROBLEM
