Interdisciplinarity is a new epistemological structure which enjoys its own linguistic characteristics and emanates from internal relations among elements of an epistemological system, theoretical structures and social rules of the new discourse of knowledge.

The necessity of interdisciplinarity stems from mysterious spaces, conditions and circumstances which govern social spheres of human life in the age of communications in “knowledge-based” societies and “virtual” worlds
