Marxism conceives of the new system of socialism as the necessary outcome of all previous history made possible and necessary only by that previous history.

Marxism is an interpretation of history which explains the progress of society as a product of the expansion of the forces of production of the material means of life, that is, the development of economy.

Socialism is nothing more nor less than the social, political and ideological system which breaks the fetters upon economic growth created under capitalism and opens the way to a new period of economic and social expansion on a much larger scale.

I knew I could not maintain that leadership in open struggle against Moscow influence. Only two Communist leaders in history ever succeeded in doing this - Tito and Mao Tse-tung.

The stage of the development of the productive forces determines the political and ideological superstructure of society which are crystallized into a system of social organization.

The social system grows rigid but the productive forces continue to expand, and conflict ensues between the forces of production and the social conditions of production.
