Endogénéisation des règles sociales et évolutionnisme culturel chez Friedrich A. Hayek
The aim of this text is first to propose a way to resolve the duality or the contradiction in Hayek's evolutionary theory as outlined by many commentators. Secondly we aim to underline the major problem that Hayek comes up against in his attempt to develop an endogeneous specification of the rules of just conduct which govern human interactions and induce a spontaneous social order. As we shall see, evolutionism is not a relevant method to explain the transformation of social order. Nonetheless, we conclude that Hayek's conception of human action as governed by "abstract patterns" retains a certain interest.
