How « the Father » became the cause of the pathologies affecting the family. When, in the 1960s, fathers lost their control over procreation and their control over women and children, some cracks started to appear in the edifice of patriarchal domination. There followed a reaction in which all the disorders today troubling the order of the family came to be traced back to this eclipse of the father figure. From this there emerged a veritable « State psychological apparatus » (...) whose aim was the sanctification of the traditional domestic functions : the father as the figure of authority, the mother as carer. Indifferent to its social and historical dimensions, Oedipus assumed the status of a, presumably universal, « symbolic order », dominated by the father and master. MT here calls into question the entire conceptual order of Lévi-Strauss and Lacan : the idea that the foundation of power and reason is naturally a masculine prerogative. Above all else, the article calls into question the interpretation put forward by Pierre Legendre, which assigns to a (patriarchal) juridical order the task of structuring the psyche. (shrink)
