critical theory any social theory that is at the same time explanatory, normative, practical, and self-reflexive. The term was first developed by Horkheimer as a self-description of the Frankfurt School and its revision of Marxism. It now has a wider significance to include any critical, theoretical approach, including feminism and liberation philosophy. When they make claims to be scientific, such approaches attempt to give rigorous explanations of the causes of oppression, such as ideological beliefs or economic dependence; these explanations must in turn be verified by empirical evidence and employ the best available social and economic theories. Such explanations are also normative and critical, since they imply negative evaluations of current social practices. The explanations are also practical, in that they provide a better self-understanding for agents who may want to improve the social conditions that the theory negatively evaluates. Such change generally aims at ’emancipation,’ and theoretical insight empowers agents to remove limits to human freedom and the causes of human suffering. Finally, these theories must also be self-reflexive: they must account for their own conditions of possibility and for their potentially transformative effects. These requirements contradict the standard account of scientific theories and explanations, particularly positivism and its separation of fact and value. For this reason, the methodological writings of critical theorists often attack positivism and empiricism and attempt to construct alternative epistemologies. Critical theorists also reject relativism, since the cultural relativity of norms would undermine the basis of critical evaluation of social practices and emancipatory change.
The difference between critical and non-critical theories can be illustrated by contrasting the Marxian and Mannheimian theories of ideology. Whereas Mannheim’s theory merely describes relations between ideas of social conditions, Marx’s theory tries to show how certain social practices require false beliefs about them by their participants. Marx’s theory not only explains why this is so, it also negatively evaluates those practices; it is practical in that by disillusioning participants, it makes them capable of transformative action. It is also self-reflexive, since it shows why some practices require illusions and others do not, and also why social crises and conflicts will lead agents to change their circumstances. It is scientific, in that it appeals to historical evidence and can be revised in light of better theories of social action, language, and rationality. Marx also claimed that his theory was superior for its special ‘dialectical method,’ but this is now disputed by most critical theorists, who incorporate many different theories and methods. This broader definition of critical theory, however, leaves a gap between theory and practice and places an extra burden on critics to justify their critical theories without appeal to such notions as inevitable historical progress. This problem has made critical theories more philosophical and concerned with questions of justification. See also FRANKFURT SCHOOL, LOGICAL POSITIVISM , MANNHEIM , RELATIVIS. J.Bo.
