Class (n.) is another name for the excess, the inherent division of each particular from itself.
Class (n.) is real, not symbolic. It is self-relating which is to say that it already takes its own denial or resistance into account.
Class (n.) is to be understood not in sociological terms, but as a rupture in the fabric of capitalist society that perpetually undermines any attempt at unity or coherence.
A Class (n.) that is truly upper shows itself by violating the code of honour, while the aspiring middle-class officer who follows the code doggedly produces only awkward ridicule.
Class (n.) is not a part of the social body but a category of the real of struggle cutting across the whole, preventing it from becoming a totality.
Class (n.) belonging is never a purely objective fact: Marx's Capital breaks off just where class was to be defined, because at that point analysis must give way to struggle.
