The hope may be entertained that some practitioner of the "sociology of knowledge" will one day have an interesting story to tell about -why the work of Michel Foucault generated such wide enthusiasm among certain intellectual elites for several decades in the latter half of the twentieth century. One or two hypotheses of my own may be hazarded. What is interesting about Foucault's unique rhetoric is that he steadfastly resists pronouncing explicit moral-political judgments, yet of course he is judging all the time. Foucault refuses to come clean on his normative commitments, but rather "insinuates" them throughout his work. This constitutes a kind of radical-left positivism that is somehow potently attractive to what I will call the hyper-liberal ethos of late modernity. The idea here is that one must avoid at all costs spelling out a normative vision, since it would ineluctably become the ground for a repressive regime of "normalization." This is clearly connected to the negativism one associates with postmodern writers.
