Karl Marx was born at Trier on 5 May 1818, the child of Jewish parents with a long rabbinical tradition on both sides. His grandfathers were rabbis; … - Leszek Kołakowski

To prevent the starving peasants from fleeing to the towns an internal passport system was introduced and unauthorized change of residence was made punishable with imprisonment. Peasants were not allowed passports at all, and were therefore tied to the soil as in the worst days of feudal serfdom: this state of things was not altered until the 1970s. The concentration camps filled with new hordes of prisoners sentenced to hard labour. The object of destroying the peasants’ independence and herding them into collective farms was to create a population of slaves, the benefit of whose labour would accrue to industry. The immediate effect was to reduce Soviet agriculture to a state of decline from which it has not yet recovered, despite innumerable measures of reorganization and reform. At the time of Stalin’s death, almost a quarter of a century after mass collectivization was initiated, the output of grain per head of population was still below the 1913 level; yet throughout this period, despite misery and starvation, large quantities of farm produce were exported all over the world for the sake of Soviet industry. The terror and oppression of those years cannot be expressed merely by the figures for loss of human life, enormous as these are; perhaps the most vivid picture of what collectivization meant is in Vasily Grossman’s posthumous novel Forever Flowing.

Of the radical and iconoclastic ideals preached in the early years of the revolution, all were discarded except those which helped the state to exert absolute control over the individual. Hence the idea of collective education and reduction of parental authority to the minimum continued to hold sway, but an end was put to “progressive” educational methods designed to promote initiative and independence. Strict discipline became once more the rule, and in this respect Soviet schools differed from Tsarist ones only in the immensely increased emphasis on indoctrination. In due course, puritanical sexual ethics were restored to favour. (pg. 53)

I do not know what postmodern is and how it differs from the premodern, nor do I feel that I ought to know.
