Abstract

This essay provides a comprehensive and critical introduction to ideology. It traces the origins and development of various conceptions of ideology, articulating both what they have in common and their differences. Among the distinctions that we develop are the contrasts between pejorative and nonpejorative conceptions, functionalist and causal conceptions, and conceptions that limit ideologies to supporting existing oppressive orders and those that allow for ideologies that challenge such orders. We also explain the role that ideologies can play in either preventing or facilitating social movements to overturn or improve existing institutions. The concluding section of this essay provides a list of important topics for future research on ideology and emphasizes that, in each case, an interdisciplinary approach is needed to understand them fully.
