"The proliferation of theories also produced a tendency to use the term "Theory" (with a capital T) to describe the wealth of conflicting critical theories. In this sense, Theory replaces philosophy as the most abstract and general model of theoretical discourse. Theory has emerged as an autonomous enterprise in many academic disciplines, giving rise to a tendency to do work in Theory, which engages various critical theories, problems, and concepts, or provides diagnosis of the nature and function of theory itself in the academic disciplines."
