It is a puzzle that Marx did not write about class consciousness. His emphasis, in The Communist Manifesto and elsewhere, is about organizations and communication. To understand Marx’s views about the proletariat as a revolutionary agent, it is necessary to understand his views about class, about consciousness, and about unity. The discussion raises subtle but critical questions about individual and collective interpretations. It also leads to important questions about organization.
