Abstract
This paper seeks to address two lacunae of the literature about French political theory in the second half of the 20th century. The first concerns the origins of the great Foucaldian thesis of the autonomy of power, and the second concerns the conceptual implications of the events of the 1950s surrounding the politics of communism on both sides of the Iron Curtain. There are many apparent responses to these questions in the existing literature. However, they are rendered insufficient by their refusal to address the need for a specifically intellectual history. With regard to Foucault’s thesis of the autonomy of power, philosophers seem happy to abstract Foucault’s insight from its context, resting on the implication that it may have come out of nowhere. Conversely, when it comes to the implications of historical developments on political philosophy, historians seem to satisfy themselves with wordplay: before so many histories of the intellectuals, who needs intellectual history? It is however rather obvious that both history and philosophy are set to benefit from a specifically intellectual history, that is to say, from an account neither of an idea nor of a context, but of how the historical context of the early fifties made the Foucaldian idea conceivable.
