Two Never's: No matter what kind of social form, it will never die before all the productive forces it can accommodate are brought into play; In the embryo of the old society, the new and higher relations of production will never appear before the conditions for its material existence are ripe.
The scientific conclusions of Marx and Engels on "Two Inevitabilities" pointed out the direction for the proletarian revolutionary struggle. Under the guidance of this scientific conclusion, the world proletariat won the victory of the world socialist revolution through hard struggle.
Extended data:
Whether the historical inevitability of socialism replacing capitalism can become a reality depends, in the final analysis, on the development level of productive forces and the maturity of corresponding production relations.
Capitalism will not retreat from the historical stage until the development level of productive forces and the corresponding production relations are fully developed. * * * Materialism will not be realized overnight.
Only on the basis of full and highly developed socialist society can it be realized. It will be a society with great material wealth, great improvement of people's spiritual realm and free and all-round development of everyone.
The realization of such a society is bound to be a long and tortuous historical development process. This laid a theoretical foundation for putting forward the highest and lowest programs of proletarian political parties.
