Une nouvelle approche de l’idéologie en économie

In this paper we expose a new conception of ideology which is different from the sociological one, notably the one developped by Marx. As we know, Marx’s conception has several limits. The principal one is generally referred to as the Mannheim paradox. To avoid this difficulty, we propose a new conception of ideology based on cognitive specification of knowledge which distinguishes the major forms of learned discourse : the scientific, the philosophic and the ideological ones. These cognitive strategies of knowledge are called the pure forms of thought. The two main caracteristics of the ideological pure forms of thought are the followings : the first one is that the belief is (psycho)logically primary, its justification opportune ; the second one explicits an ontological principle deciding the essential articulation between two separate entities, man and society. This new approach of ideology allows us not only to forget about the Mannheim Paradox, but also to treat different applications in economic literature.
