The subject of power as it plays out in the therapeutic situation has come rather late to the psychoanalytic literature (Leffert, 2010a, especially chapters 1 and 7 ). However, its relevance to the wider areas of the treatment of people termed mentally ill and its presence in social relations generally has been a subject of inquiry and discourse in other disciplines for many decades. Foucault (1961/2006a), in his monumental work History of Madness , offers a history of society’s dealings with both madness ( folie ) and the mad ( fou ) from the 17th to the beginnings of the 19th century. Trained as a clinical psychologist as well as a philosopher, he portrays the relationship in terms of power and fear of contagion. The fou are to be corrected, linking them to the second of Foucault’s (1979/1995) great concerns, the prison and the imprisoned.
