This paper examines the conundrum within which the discipline of Korean sociology finds itself, then offers a new direction for sociology going forward. The objective is to offer a response to concerns of sociology’s diminishing application in society, and to find an appropriate resolution and road map for its future. The common criticism held against sociology nowadays are the weakness of resolution for societal problem, the lack of dialogue with society itself, the inadequate sensitivity toward new data, and the perceived demotion of sociology’s status as a study field. This paper offers the suggestion of augmenting the identity of sociology as we know it by tackling the previously shunned task of designing the future of social communities. The assignment of building sustainability in Korean society will be discussed through the five aspects of population, growth, trust, politics, and integration. We suggest the goal of sociological research must be changed from description to prediction, from interpretation to prescription, and from explanation to prevention. Simultaneously, major reassessment of analysis tools and methodology must take place by sociologists, in addition to the adoption of more active sensitivity towards integrating the enormous amount of information data collected in the digital age of the 21st century.
