"Nietzsche's importance to Foucault can be seen as 'correcting Marx', especially in relation to the linkage between power-knowledge-truth, and the functioning of knowledge as an instrument of power. As Alan Schrift (1993, p.40) notes, Nietzsche's influence drew attention away from 'substances, subjects and things, and focussed attention instead on the relations between these substantives'. In a related way, Foucault 'draws our attention away from the substantive notino of power and directs our attention instead to the multifarious ways that power operates through the social order'. For Nietzsche, such relations were relations of forces. Foucault thus focussed on new relations as the relations of forces that existed and interacted within social systems as social practices. These were forces of repression and production that characterised the disciplinary society: forces that enable and block, subjugate and realise, and normalise and resist. In this model, power is not a thing, but a process, a relation of forces." (Mason, 2008: 92)
