Distinguished French sociologist Raymond Boudon presents here a critical theory history of the concept of ideology. His highly original and lucidly argued study addresses the core question of any account of ideology. How do individuals come to adhere to false or apparently irrational beliefs, and how do such beliefs become collectively accepted as true?

Boudon begins by providing an exhaustive and subtle critique of sociological explanations of ideology from early conceptions to its current usage in the works of Barthes, Foucault, Habermas, Sartre, and others. He then offers his own interpretation of the origins and emergence of ideological beliefs. In opposition to those views which associate ideology with irrationalism, Boudon shows that ideologies are a natural ingredient of social life; he develops a rationalist theory that helps to explain why certain ideas are believed by individuals and thereby effective in the social world. Finally, he examines case studies of two modern-day ideologies—developmentalism and Third Worldism.

Moving easily across disciplinary boundaries, Boudon's provocative contribution to a subject of growing significance will be of great interest to scholars in sociology and social theory, as well as philosophy, political science, and development studies.

This distinguished reference work is much more than a lexicon or ordinary dictionary. Each essay, complete with bibliographical references, presents a selective and critical discussion of some issue fundamental to sociology. Synthesizing American, British, French, and German, taken together these contributions provide a coherent and sophisticated critique of the sociological tradition.

Without Paul F. Lazarsfeld the social sciences would not be what they are today. In his ground-breaking work on unemployment, voting, consumer behavior, and social influence, among other subjects, his methodological emphasis on vigorously controlled scientific language and structures transformed social research worldwide.

Lazarsfeld's systematic criticism of observational, conceptual, and inferential procedures in sociology led to the the formation of universally applied observational and analytical techniques, such as the panel design of observation and contextual and multivariate analysis. His methodology for empirical social research had a profound effect on all the social sciences.

The eighteen essays in On Social Research and Its Language illustrate the diversity of Lazarsfeld's substantive, methodological, and organizational interests. Spanning the years 1933 to 1972, they encompass his own works of social research, as well as writings on methodology and the history and sociology of social research. Articles on methodology—observing, classifying and building typologies, analyzing the relations between variables, qualitative analysis, and macrosociology—form the bulk of the book. In addition, Raymond Boudon provides a revealing biography of Lazarsfeld and his influence on sociology.

These classic writings by a formative figure of modern social science will be an indispensable reference for scholars across the historical and social science disciplines.
