Freedom is an abstract concept which is more understandable by its limitations. The question is that, is there a comprehensive concept of freedom in western idealism? For this purpose, this study created some conceptual research in the poles of western idealism. Accordingly, freedom in framework of Socratic philosophy had no context except virtue orientation. Then, it was reduced to security and property in the new period. The present study used the discourse analysis of freedom to show why and how the concept of freedom has an underlying and philosophical concept in old and new schools. Thus, a single and undeniable attitude to freedom in western idealism is non-scientific and non-historical. The present study selected the analytical comparative method to discuss the concept of freedom discourse in western political thought in old and new periods, indicating why and how freedom is a discourse concept; or at least belongs to its specific community, and cannot be necessarily compared in a generalized, universal way.
