"Two widespread assumptions lay behind such thinking, shared very broadly across the intellectual community of the time. The first was that power rested not—as most social thinkers since the Enlightenment had supposed—upon control of natural and human resources, but upon the monopoly of knowledge, knowledge about the natural world; knowledge about the public sphere; knowledge about oneself; and above all, knowledge about the way in which knowledge itself is produced and legitimized. The maintenance of power in this account rested upon the capacity of those in control of knowledge to maintain that control at the expense of others, by repressing subversive 'knowledges'. At the time, this account of the human condition was widely and correctly associated with the writings of Michel Foucault. But for all his occasional obscurantism Foucault was a rationalist at heart. His early writings tracked quite closely the venerable Marxist claim that in order to liberate workers from the shackles of capitalism one had first to substitute a different account of history and economics for the self-serving narrative of bourgeois society. In short, one had to substitute revolutionary knowledge, so to speak, for that of the masters: or, in the language of Antonio Gramsci so fashionable a few years earlier, one had to combat the 'hegemony' of the ruling class."
