A Transdiscursive Man
Foucault gave us the term transdiscursive, which describes how, for example, Foucault is not simply an author of a book, but the author of a theory, tradition or discipline.
We can at least say that he was the instigator of a method of historical inquiry which has had major effects on the study of subjectivity, power, knowledge, discourse, history, sexuality, madness, the penal system and much else. Hence the term, "Foucaldian".
There are many "Foucaults" - whether they are all texts, or features in a network of institutional power, a regime of truth and knowledge, or the discourse of the author and his works. Let's explore the many layers of Foucault.
