Foucault's achievement in so quickly building such an enthralling account of the operation of power in society is all the more remarkable when one remembers the dominant hold that Marxist and neo-Marxist accounts had in the Anglophone academy in the 1970s and even into the 1980s. The key to his success probably lies in the fact that he did not initially present his insights in abstract terms but instead allowed them to emerge from his painstaking histories of various knowledge endeavours, or sciences, particularly psychiatry, psychology, penology, and sexology. Without bludgeoning his readers, Foucault allowed them to see mostly power where others would see mostly science.
