Suddenly, the revolutionary movement and the workers' movement were no longer identical, revealing theImaginary Party as an excess relative to the latter. The motto, 'class against class,' which from 1926 had become hegemonic, only reveals its latent content if we note that it predominated exactly at the moment when all classes began to disintegrate under the effect of the crisis. 'Class against class' actually means 'classes against the non-class'; it belies the determination to reabsorb, to to liquidate this evermore massive remainder, this floating, socially unaccountable element that threatens to undermine every substantialist interpretation of society, be it bourgeois or Marxist.
