Did Marx have a particular way of thinking of 'power', be that communist power, proletarian power, or bouregois power, in particular before the international revolution? The communist manifesto begins and ends
I. Communism is already acknowledged by all European powers to be itself a power... The Communists disdain to conceal their views and aims. They openly declare that their ends can be attained only by the forcible overthrow of all existing social conditions. Let the ruling classes tremble at a Communistic revolution. The proletarians have nothing to lose but their chains. They have a world to win.
Is this just rhetorical or is he suggesting that, in matters of class struggle at least, the working class is powerless and the communist vanguard are ascendant? If so, in what way?
