Power is not founded on itself or generated by itself.Or we could say, more simply, that there are not first of all relations of production and then, in addition, alongside or on top of these relations, mechanisms of power that modify or disturb them, or make them more consistent, coherent, or stable.
Third, the analysis of these power relations may, of course, open out onto or initiate something like the overall analysis of a society.
The analysis of mechanisms of power may also join up with the history of economic transformations, for example.
What's more, in the different mechanisms of power intrinsic to relations of production, family relations, and sexual relations, it is possible, of course, to find lateral co-ordinations, hierarchical subordinations, isomorphic correspondences, technical identities or analogies, and chain effects.
This allows us to undertake a logical, coherent, and valid investigation of the set of these mechanisms of power and to identify what is specific about them at a given moment, for a given period, in a given field.
So, insofar as what is involved in this analysis of mechanisms of power is the politics of truth, and not sociology, history, or economics, I see its role as that of showing the knowledge effects produced by the struggles, confrontations, and battles that take place within our society, and by the tactics of power that are the elements of this struggle.
