Historical Knowledge as Perspectival and Rational: Remarks on the Annales School's Idea of History

There is an obvious parallel between foundationalism, which ignores history in working out the conditions of knowledge, and radical relativism, which contends that by virtue of its own historical character there is no way to choose among different interpretations, all of which are “equally good.” Might it not be, rather, that the recent historicist attack on the very idea of rationality is as damaging as foundationalist objections against the plurality of conceptual schemes or frameworks? Can philosophy maintain the traditional distinction between the form and content of knowledge, between rationality and historicity _ between doxa and episteme?
