I found a line in my book which says something like this:
Michael Foucault's main job is to historicize discourse and textualize history.
The context of this quote is the following (from a course book by K.P Subedi and Subhas Giri):
After discovering the rules of a particular discourse, Foucault relates them to the study of knowledge and power. His job is to historicize discourse and textualize history. Foucault refuses to see history in terms of linearity and development. He sees history in terms of a kind of power struggle of particular time. According to Foucault, power is not repressive and tyrannical rather it is generative and productive force. Power binds together the disparate forces of a society. every event is the product of a vast network of signification and power rather than originating from a single, coherent cause.
I couldn't quite get this concept.
Does he want to say that discourse created history and history is created through text? I couldn't understand the concept, please make it clear to me.
