The main theme of this thesis is to study the textual interpretation with respect to language as the medium of Thinking and Being and its speculative structure in Gadamer’s Truth and method. Namely, in this thesis, there is an investigation of Greek metaphysics, modern science methodology and hermeneutical experience from the aspects of words, belonging, dialectic and speculativeness. This thesis also explores Gadamer’s criticism and transformation of the idea of Hegel’s dialetical philosophy.
