Literature and criticism as discipline of knowledge reflect the omnipresence of life. Historically, the phenomena of unity of knowledge is very old. The industrial needs of modern societies promoted the trend of specialization in various sciences to drive the industry. The classification of sciences as isolated disciplines, instead of assisting in the revelation of reality, made it more obscure. In this situation, the concept of interdisciplinarity emerged with the idea that the sciences are personally related to each other and can support each other in the understanding of facts. Interdisciplinarity insists on the interconnectedness of sciences. In this paper, the interrelationship between literature and environment has been explained based on the philosophical point of view of the unity of knowledge. Examples from Urdu literature are given to explain this connection. Thus, not only the interrelationships between Urdu literature and environment have been revealed, but also the interdisciplinary potential of Urdu literary studies has been revealed.
