“The proletariat should not be viewed as a monolithic entity represented by a single party (a la the various currents of Marxism) but rather as a contested body whose unity is contingent on the freedom of its different parts to fight for their interests within it. The fight for women’s liberation or the recognition of the rights of various ethnic groups then are not battles to be put off until after the proletariat seizes power globally, but are necessary precursors to that seizure of power that clarify the revolutionary orientation of the proletariat.”
