Crisis has become such a ubiquitous word that its discriminatory power is diminished across various disciplines. It challenges the word-concept relationship inasmuch as it is associated with a host of partner words that imbue crisis with divergent meanings. Not least, it stretches between major upheavals and minor disturbances, often employed with calculating or rhetorical dramatic effect. This article explores both professional and vernacular usages of “crisis” and notes the distinction between theories of crisis and ideologies of crisis. It then turns to examining two domains closely linked to the language of crisis: Marxist analyses of capitalism, and legitimation problems. The latter is explored particularly through Seymour Martin Lipset and Jürgen Habermas. The role of crisis as filtered through different ideological families is indicated. Finally, the relationship between the tipping-point connotations of crisis and the finality drive of political decisions is considered.
