In this section of Chapter Two - ‘Proletarians and Communists 23’ - the Manifesto contains two important Marxist ideas: (1) that “conditions determine consciousness” and (2) how the State can finally ‘wither away’ once classes have disappeared.
The paragraphs continue on from those highlighted in the previous lessons:
(The content has been abridged to give a more concise selection of quotes)
The ruling ideas of an age are the ideas of its ruling class
“Does it require deep intuition to comprehend that man’s ideas, views, and conception, in one word, man’s consciousness, changes with every change in the conditions of his material existence, in his social relations and in his social life?
What else does the history of ideas prove than that intellectual production changes its character in proportion as material production is changed? The ruling ideas of each age have ever been the ideas of its ruling class.
When people speak of the ideas that revolutionise society, they do but express that fact that within the old society the elements of a new one have been created, and that the dissolution of the old ideas keeps even pace with the dissolution of the old conditions of existence”.
“… The history of all past society has consisted in the development of class antagonisms, antagonisms that assumed different forms at different epochs. But whatever form they may have taken, one fact is common to all past ages, that is the exploitation of one part of society by the other. The Communist revolution is the most radical rupture with traditional property relations; no wonder that its development involved the most radical rupture with traditional ideas”.
Building a classless society
[… jumping ahead to the very final paragraphs of the chapter:] “When, in the course of development, class distinctions have disappeared, and all production has been concentrated in the hands of a vast association of the whole nation, the public power will lose its political character. Political power, properly so called, is merely the organised power of one class for oppressing another. If the proletariat … by means of a revolution … makes itself the ruling class, and, as such, sweeps away by force the old conditions of production, then it will … have swept away the conditions for the existence of class antagonisms and of classes generally, and will thereby have abolished its own supremacy as a class. In place of the old bourgeois society, with its classes and class antagonisms, we shall have an association, in which the free development of each is the condition for the free development of all”.
