Louis Althusser : mai 1968 et les fluctuations de l'idéologie
Louis Althusser, May 1968 and the Fluctuations of Ideology 
By examining the various statements made by Louis Althusser of his position on the student movement of May 69, the article seeks to reveal the remarkably complex and theoretically apposite 
character of his assessment. e article thus goes against usual interpretations of this issue. In 
particular, it points to the interest of the concepts of revolt and of mass ideological revolution, which 
were introduced in his writing of the period. By demonstrating that Althusser’s analysis of the 
function and status of ideology in the revolts of May validates the theses which he advanced in 
For Marx about the notion of overdetermination, the author’s intention is to assess the role played 
by this paradigmatic spectrum in the overall reconstruction of the problematic of ideology which 
Althusser was to formulate in the famous manuscript entitled On Reproduction. e principal 
interest of this manuscript is that, for the first time, it establishes a rigorously materialist conception of ideology and of the concrete mode of existence of ideas.
