Ivan Ascher University of California, Berkeley Department of Political Science ascher@socrates.berkeley.edu Theory, Practice and Theater Insofar as practice is that which defies and defines theory, the Marxian project of critical-revolutionary Praxis runs the risk of being aporetic. That is why Marx, this paper argues, deploys distinctly theatrical tropes and metaphors in an effort to steer clear of the contradiction while working to resolve it once and for all. Without following the Althusserian line, one can readily distinguish in Marx two forms of theorizing, two theoretical practices: one, displayed in the German Ideology or the 1844 Manuscripts, is parasitic on the discourses it critiques, and suffers from the same shortcomings it identifies in others. The other is a theatrical form, encountered in the Eighteenth Brumaire of Louis Bonaparte, the Manifesto of the Communist Party, and in Capital; it is less obviously aporetic, partly because it is cast in terms that accommodate both the distinction of theory and practice and their fundamental connection. Ultimately, however, even the theatrical model of critique cannot sustain or accomplish the project of revolutionary Praxis, if only because it necessarily relies on generic categories of Tragedy and Comedy, which, inherited from a Hegelian tradition, both precede and outlast what resolution they promise.
