Abstract
To reinvigorate the present inquiry into places of power by considering how heterotopias space out time, the session proposes an excursus into the history of contemporary thought : how, in 1966, was Michel Foucault able to integrate his proposals on " espaces autres " into a more general reflection on the body and utopia ? And why is this reflection inseparable from a deeper concern about the percussive powers of the voice ? This double questioning must undoubtedly be seen in the collective context of the great debates on phenomenology and historicity at the time of the structuralist effervescence. The publication of several previously unpublished works by Foucault dating from the same year 1966 (notably Le Discours philosophique) also complicates our idea of the internal chronology of his work. But the hypothesis we are defending here is that it is especially important to consider the radio form of Foucauldi's proposals on the utopian body and heterotopias, in order to better understand their intimate content and collective scope. For what is ultimately at stake here is to suggest how, without seeking to ventriloquize it, Michel Foucault's voice can be heard here, and how the work of history allows us to recognize the conceptual yield of a notion like heterotopia.
