In this year’s seminar, "Crisis, Population, Archive," we look at three inter-related problems: 1) the theory of historical repetition (Marx, Deleuze, Karatani); 2) Uno Kozo's Theory of Crisis, the theory of capitalist cycles, and the theory of stages of capitalist development; and 3) the question of the historical archive and historical writing. Developing Marxist traditions and straddling disciplines in both the social sciences and the humanities, we return to past investigations of a series of critical and theoretically productive concepts for the practice of "writing history": repetition and contingency; crisis and cycles; class and surplus populations; and state power and stages of capitalist development. The goal of this conceptual itinerary is to develop a method to approach the historical archive, and ultimately to transform existing archives, which, under the monopolization and despotism of the state, tend towards positivism ("facts") and quantitative abstractions ("statistics"). In transforming existing archives, we instead produce, document, and write what Lenin called "the concrete analysis of the concrete situation", or 現状分析. The analysis of the "concreteness" of the "situation," however, requires that we carefully analyze questions of materialism, ideology, the historical present, and the treacherous and dis-Orient-ing ideologies of capitalist, imperialist, and colonial modes of representation.
