the multilinear relation be1ween concepts and evidences

concepts are considered as the tools of political analysis, and without recognition of the concepts, particularly the concept of state, there is no possibility for us to have knowledge of the world of politics. parallel to the external developments, concepts are also growing fatter and more dynamic in modern age. this development may be explained through two approaches: approach of interpretive sciences and approach of political thought. in the first approach, methods such as hermeneutics, modern phenomenology, linguistics, discourses and signifier-signified position, semiology, chronology and foundation breaking are employed. in this approach development in concepts is taken for granted. in the second approach, there is a kind of similarity between the ways of development in the concepts of the politics and the concept of state. this article discusses the matter of multilinear relation between concepts and evidences in political thought.
