The assertion of the priority of contemporaneity, the celebration of the present, defines the politics of periodization. It is either a matter of our present, defined as the vanguard of historical progress, or it is the historical present of the objects of study, presumed to be fully grounded in that single, isolated moment of time. In either case, the classificatory impulse inherent in periodization tends to proscribe the more complex temporalities of tradition and anticipation.
