The proletariat wants to possess all its life, to possess it as life, as the totality of its possible realization.
Gianfranco Sanguinetti and Guy Debord, La véritable scission dans l'Internationale
The proletariat has not been eliminated. It remains irreducibly present within the intensified alienation of modern capitalism. It consists of that vast majority of workers who have lost all power over their lives and who, once they become aware of this, redefine themselves as the proletariat, the force working to negate this society from within.
Guy Debord, La société du spectacle §114
But when the proletariat discovers that its own externalized power contributes to the constant reinforcement of capitalist society, no longer only in the form of its alienated labor but also in the form of the labor unions, political parties, and state powers that it had created in the effort to liberate itself, it also discovers through concrete historical experience that it is the class that must totally oppose all rigidified externalizations and all specializations of power.
Guy Debord, La société du spectacle §114

The dictatorship of the proletariat is a relentless struggle, bloody and bloodless, violent and peaceful, military and economic, educative and administrative, against the forces and traditions of the old society.
