This chapter traces to what extent dialectics is an epistemological concern in Wilhelm Dilthey, E. Husserl, Georg Simmel and Max Weber. For Simmel, dialectics is a sort of methodological fragmentation, in the manner of the individual and society. By evaluating (implicitly) dialectics and (explicitly) scientific intersubjectivity, Simmel assesses the essence of his dual schema of forms and concepts, where both constitute the scientific criteria of the humanities. From a study of methodology, Dilthey proceeds to the philosophical contribution of epistemology and the epistemological contribution of philosophy to science. Philosophy and epistemology are pivotal parts of his theoretical concerns, without ever losing their conceptual equality in his work. Phenomenology's hermeneutic turn was inaugurated by Martin Heidegger. To be more precise, the hermeneutic turn that Heidegger introduced was an ontological turn of phenomenology, probably against Husserl's epistemological transcendentalism of the eidetic reduction.
