The term hermeneutics covers both the first order art and the second order theory of understanding and interpretation of linguistic and non-linguistic expressions. As a theory of interpretation, the hermeneutic tradition stretches all the way back to ancient Greek philosophy. In the course of the Middle Ages and the Renaissance, hermeneutics emerges as a crucial branch of Biblical studies. Later on, it comes to include the study of ancient and classic cultures.

With the emergence of German romanticism and idealism the status of hermeneutics changes. Hermeneutics turns philosophical. It is no longer conceived as a methodological or didactic aid for other disciplines, but turns to the conditions of possibility for symbolic communication as such. The question “How to read?” is replaced by the question, “How do we communicate at all?” Without such a shift, initiated by Friedrich Schleiermacher, Wilhelm Dilthey, and others, it is impossible to envisage the ontological turn in hermeneutics that, in the mid-1920s, was triggered by Martin Heidegger’s Sein und Zeit and carried on by his student Hans-Georg Gadamer. Now hermeneutics is not only about symbolic communication. Its area is even more fundamental: that of human life and existence as such. It is in this form, as an interrogation into the deepest conditions for symbolic interaction and culture in general, that hermeneutics has provided the critical horizon for many of the most intriguing discussions of contemporary philosophy, both within an Anglo-American context (Rorty, McDowell, Davidson) and within a more Continental discourse (Habermas, Apel, Ricoeur, and Derrida).
