The book’s Introduction addresses the ways in which the notion of crisis functions conceptually to name not only moments of economic and cultural rupture, which become normalized within capitalist modernity, but also moments of epistemological doubt, when the taken-for-granted relationship between language and the social is called into question and subjected to critique. The Depression represented not only a breakdown of the smooth functioning of modernity and its market-based social organization, but also a parallel breakdown in a collective investment in the idea that language can represent the social, as language came to be regarded with suspicion for its role in perpetuating forms of commodification and appropriation associated with a crisis-ridden modernity. In response to this crisis, poetic language was forced to reconfigure its relationship to a society that was itself always in flux. The book’s Introduction thus establishes a basis for its survey of a broad cross-section of the poetic idioms associated with the Depression as both critiques of the idea of market modernity as a progressive, developmentalist force, and efforts to shore up language’s efficacy as a social and cultural form.
