Abstract
Even while still in Germany, Karl Mannheim was famous for his work in the “Sociology of knowledge.” After he sought political asylum in the United Kingdom, he introduced psychology and policy science into his theoretical framework and analyzed characteristics of mass society. Meanwhile, he was changing his focus from “diagnosing society” to “planning a new society.” As a result, he created a “social planning” concept. This paper investigates how Mannheim developed his ideas of “social planning.” What attracts me most is his idea of “coordination of social technique.” Through analyzing his works, I would like to point out a common theoretical basis in Mannheim's Britain-era thinking.
