“And the great problem presented by such historical analyses is not how continuities are established, how a single pattern is formed and preserved, how for so many different, successive minds there is a single horizon, what mode of action and what substructure is implied by the interplay of transmissions, resumptions, disappearances, and repetitions, how the origin may extend its sway well beyond itself to that conclusion that is never given – the problem is no longer one of tradition, of tracing a line, but one of division, of limits; it is no longer one of lasting foundations but one of transformations that serve as new foundations, the rebuilding of foundations. What one is seeing, then, is the emergence of a whole field of questions, some of which are already familiar, by which this new form of history is trying to develop its own theory: how is one to specify the different concepts that enable us to conceive of discontinuity (threshold, rupture, break mutation, transformation)? By what criteria is one to isolate the unities with which one is dealing; what is a science? What is an oeuvre? What is a theory? What is a concept? What is a text? How is one to diversify the levels at which one may place oneself, each of which possesses its own divisions and form of analysis? What is the legitimate level of formalization? What is that of interpretation? Of structural analysis? Of attributions to causality?”
– Foucault, The Archaeology of Knwowledge, p. 5-6
It’s paragraphs like these that remind me why I am doing a PhD.
