Subjectivity is the mother of all social sciences. There is no universal truth, there is no objective reality and there is no finality in social sciences. Final truth belongs to heaven, not to this world and none of the theories can claim finality or objectivity. Nonetheless, theories try to explain the truth, holding water, either more or less. Theories, highlighting the intrinsic nature of humans [good & bad], the structure of international system (anarchic)or class struggle[bourgeois & proletariat]are both researchable and discernible. Social Constructivism, on the other hand labels all the theories as social constructions and itself constructs an endless desert of ideas, develops absurdity, and makes the truth less accessible and more mythical. Social Constructivism, instead of explaining the truth is making it blurred and doubtful. Instead of ensuring clarity, its own assumptions are constructing a mythical world. This analytical paper critically analyzes the social constructivists' assumptions and their critique on all the established beliefs in general and mainstream perspectives in particular.
