Communicative Action Theory (lifeworld and System) and Social-Political Critique.

Evaluation of different aspects of modern society by using two concepts of “lifeworld” and “system” is one of the most important social-philosophical efforts made by Jürgen Habermas during 1970s. The main argument here is the fact that every social system needs a minimum of cohesion without which it will face crisis.However this social cohesion is not merely a product of system requirements. It also must be regarded as a language-culture phenomenon in which language and culture play a role. Expanding of the system in a variety of social spheres has shaken the foundations for such a cohesion. The article suggests that with a few modifications too this theory one can study the current Iranian society.
