This article seeks to rehabilitate the concept of ideology as a necessary tool of struggle against present-day capitalism. Post-structuralist epistemologies, by celebrating pluralism and the emergent character of knowledge and politics, have rendered the intellectual production of a unitary theory an obsolete remnant of a Modernist past. I contend that these well-meaning anti-authoritarian epistemologies unwillingly express the hegemony of a form that the Austrian school proposed for market competition in the first half of the 20th century. Based on ethnographic material of Spain, I acknowledge the need to develop a new conceptual framework that captures the singular experienced realities of the present but links them in a coherent unitary theoretical structure. The productive power of the 'hegemony of form' requires the construction of an ideology that may not only destroy it but also provide the basis of a counter-hegemony for producing a better future.
