"The work is celebrated among Marxists for being one of Marx's most detailed pronouncements on programmatic matters. It offers his most extensive statements on the nature of a hypothetical future communist society, the strategy for achieving it, and the principles that would govern it. The Critique outlines the "two phases of communist society" as predicted by Marx: a lower phase where individuals receive goods equivalent to their labour contribution, and a higher phase in which society operates on the principle, "from each according to his ability, to each according to his needs". It also contains Marx's only sustained discussion of the "dictatorship of the proletariat" as the posited form of governance during the projected transition period between capitalism and communism." <

"The document was originally suppressed by the party leadership, who feared it would disrupt the unity congress, and was not published during Marx's lifetime. Friedrich Engels, who shared Marx's objections to the programme, published the Critique in 1891, as the newly formed Social Democratic Party of Germany (SPD) was drafting a new programme. Its publication was controversial within the party but helped to solidify its theoretical basis. The text became a foundational work for later Marxist thinkers, particularly Vladimir Lenin, whose book The State and Revolution is in large part an elaboration of the ideas in the Critique of the Gotha Programme."<



"What we have to deal with here is a communist society, not as it has developed on its own foundations, but, on the contrary, just as it emerges from capitalist society; which is thus in every respect, economically, morally, and intellectually, still stamped with the birthmarks of the old society from whose womb it emerges. Accordingly, the individual producer receives back from society – after the deductions have been made – exactly what he gives to it. What he has given to it is his individual quantum of labor. For example, the social working day consists of the sum of the individual hours of work; the individual labor time of the individual producer is the part of the social working day contributed by him, his share in it. He receives a certificate from society that he has furnished such-and-such an amount of labor (after deducting his labor for the common funds); and with this certificate, he draws from the social stock of means of consumption as much as the same amount of labor cost. The same amount of labor which he has given to society in one form, he receives back in another."
