The aim of this study is to specifically evaluate how hermeneutical consciousness as represented in Hans-Gadamer’s philosophical hermeneutics- is formed in some ways in reaction to Rene Descartes’s methodological consciousness. This consciousness indicates a concept of rationality which is based on subjectivity. According to the subject- based concept of wisdom, the origin of rationality is an abstract mind which is opposed to the objective world as a subject of knowledge. But from one point of view, hermeneutic consciousness- which seeks to establish the concept of rationality on the basis of an interpretation of intersubjectivity- is formed in reaction to the results of subject- based rationality. In addition, this paper discusses some results and political implication of philosophical hermeneutics.
