Han Sang-jin (; born February 1945) is a South Korean sociologist in the tradition of critical theory, known for his Joongmin theory. He is professor emeritus at the department of sociology, Seoul National University, Korea, and a distinguished visiting professor at Peking University, China. He has lectured as visiting professor at Columbia University in New York, United States, School for Advanced Studies in the Social Sciences in Paris, France, the University of Buenos Aires in Argentina, and Kyoto University in Japan. His major areas of interest are: social theory, political sociology, human rights and transitional justice, middle class politics, participatory risk governance, Confucianism and East Asian development.

From childhood to college years

Han was born in a small rural village in Imshil, North Jeolla Province, Korea in February, 1945. The village he was born in was famous for the upbringing of intellectuals and was called "doctors' village" because it produced many Ph.D.'s in various fields. The year 1945 was the time when Korea was liberated from the colonial rule of Japan. As one of the so-called "emancipation babies" he later served as the executive chairman of the committee for the 1960s commemoration of Gwangbok (Regaining light and liberation) in 2005 and began to explore the complex meaning of Gwangbok.2005 "Reflections on the 60th Anniversary of Korean Liberation", Korean Policy Review, September, 2005, 18-22. 2016 "March 1st Independence Movement of 1919 and the Identity of Korea: The Relationship between Gwangbok and Geonguk (State Building)", Public Lecture in Commemoration of March 1st Independence Movement at Seoul National University, Joongmin Foundation for Social Theory: 4-29 (in Korean). His life was inevitably intertwined with the turbulent history of Korea.

Han experienced the Korean War (1950–53) in his early childhood and the April student revolution (1960) when he had just entered high school. In 1963, he became a student of sociology at Seoul National University. From 1964 a strong nationalist movement against the Korea-Japan normalization treaty swept over university campuses. While supporting such opposition to the Japanese colonial legacy, he felt the need to explore the constructive goal of development for the future of Korea and thus founded a "Study Group of the Korean Thought" with classmates of social sciences in 1965.2015 "Relations with Teacher starting from <Study Group of Korean Thought>", The Commemoration Book for Professor Ko, Byung-Ik, 2014, 478-485 (in Korean) Later when he became a graduate student, he led the student movement for academic freedom and autonomy against the dictatorial regime of President Park Chung Hee. Just before the presidential election in 1971 he was arrested and put in jail and prosecuted for the violation of the Anti-communist law after severe investigation. But he was found innocent and acquitted.

Such experiences of hardship helped him realize the harsh reality of national division and ideological conflict and paved a way for him towards an academic life as a critical sociologist with a sense of balance between practice and theory.

A search for a new critical theory

Han's interest in critical theory can be traced back to the late 1960s when he was fascinated by Habermas' "Erkentniss and Interesse" and translated it into Korean. But the core of his own ideas began to be formulated in the late 1970s while he was writing his Ph.D. dissertation at Southern Illinois University, US. In 1996 when he taught at Seoul National University, he invited Habermas to Korea and organized an intensive two-week program of conferences and seminars and public lectures in many cities.1996 The New Horizon of Modernity: Habermas' Lectures in Korea (ed.), Seoul: Nanam (in Korean). 1998 Habermas and the Korean Debate, Seoul National University Press. Since then he often visits Habermas at his residence in Starnberg, Germany whenever he travels to Europe even now.

Han came to be interested in Foucault through his doctoral advisor Prof. Charles Lemert. When he attempted to link Habermas and Foucault in his dissertation in 1979, the overall academic atmosphere was that the two were so different that linking them was thought to be impossible. Against this, Han proposed an idea of "discursive methodology,' and "discursive social science" and argued that Foucault and Habermas can and should be linked. The basic idea was that discursive social science is composed of discursive analysis and discursive testing, with the former from Foucault and the latter from Habermas. So combining them, he presented discursive social science as an alternative to the outmoded versions of critical theory originating from the Marxist traditions.1979 "Discursive Method and Social Theory: Selectivity, Discourse and Crisis: A Contribution to a Reflexive Sociology Critical of Domination", Ph. D. Dissertation, Southern Illinois University. He spent two years at Bielefeld University, Germany as a postdoctoral researcher and there, collaborated with Claus Offe. After this, he became a professor at the department of sociology at Seoul National University (SNU).

Formulating Joongmin (中民) Theory in Korean society

While teaching at SNU, Han sparked off the debate on bureaucratic-authoritarian (BA) state and it helped clarify the dynamics of the state-led rapid industrialization and its consequences upon class structures and political democratization as well. The mid-1980s was the well acknowledged period of system transition. Deeply influenced by the 1980 Gwangju popular upsurge and June 10 democratization movement of 1987, Han attempted to combine critical theory with empirical studies on the newly emerging middle classes and the working class as well in order to comprehend the major agents of social change.

In this vortex period of social transformation Han proposed the theory of Joongmin<ref>1991 Searching for A Theory of 'Joongmin (Middling Grassroots), Seoul: Munjisa (in Korean).

2010 "Middle-Class Grassroots Identity and Participation in Citizen Initiatives, China and South Korea" in Cheng Li (ed.) China's Emerging Middle Class: Beyond Economic Transformation. Washington DC: Brookings Institution Press, 264-287.</ref> originating from intensive public debates. To describe it simply, Joong(中) refers to the middle class and min(民) refers to popular forces. By deliberately combining these two words, each with profound meanings, Han identified the major agent of social change from those who share the identity of grassroots people as members of the middle classes. Han argued that the BA regime in Korea was not only successful in steering continuous economic growth but also produced more and more the modernized social forces, like Joongmin, who would destroy this regime demanding for democratization and social reform.1984 Bureaucratic Authoritarianism in the Third World (ed.), Seoul: Hanwool-sa (in Korean).

1988 Bureaucratic Authoritarianism in Korea, Seoul: Munjisa (in Korean). In fact, his theory gained public recognition when a great number of white collars, professionals, and students came out to the street to join the democratic movement in 1987.

As to the method of social transformation, he clearly rejected the models of polarization strongly advocated by radical intellectuals and activists of the day.1990 "A model of Center-expanding strategy of Transformation based on Middle-way Politics: Focusing on the Concept of Joongmin," Peace Research Center, Korea University (ed.), Conflict Structure in Korean Society, Hangilsa, 84-128. (in Korean). Instead, he supported what he called a center-expanding strategy by the principle of democracy, which is close to a middle-way progressive transformation. He also offered a three-stage program of transition starting from the external pressure for change by social movement through democratizing state power to socio-economic democracy.1994 "Social Reform and Joongmin Theory: Institutionalization of Moral Resources", Sasang Quarterly, Fall, 260-283 (in Korean).

Human rights and transitional justice in East Asia

Han began to expand his research to East Asia in 1991 when he taught at Columbia University in New York as visiting professor. It helped him realize the importance of comparative study between the West and the East, on the one hand, and among the East Asian countries, on the other. Later he became president of the Academy of Korean Studies (1998–2000) and he pursued global dialogues. In particular, he became deeply interested in human rights and transitional justice in East Asia and published many papers on the Gwangju democratization movement of 1980.1999 "Popular Sovereignty and a Struggle for Recognition from a Perspective of Human Rights", Korea Journal 39(2), 184-204.

While pursuing global dialogue, however, Han kept distance from the West-centered presuppositions in social sciences. Instead, he introduced a reconstructed Confucian framework of understanding. For instance, he argued for a balance between individual empowerment and community wellbeing and also between retributive justice and reconciliation. A good case in point is his study of the Gwangju democratic movement with the focus on the experience of self-rule by citizens as an instance of communitarian human rights.2010 "Confucianism and Human Rights", Wunsuk Chang & Leah Kalmanson (eds.) Confucianism in Context: Classic Philosophy and Contemporary Issues: East Asia and Beyond, State University of New York Press,121-144.

Transitional justice in East Asia is full of ambiguities and contradictions today. Many have asked Japan to follow the German pathway. Japan has refused, however. In this situation, Han offered a communicative approach by paying sympathetic attention to the war memories of the Japanese citizens.2012 "Divided Nation, Unification and Transitional Justice: Why do we need a Communicative Approach?" (ed.), Divided Nations and Transitional Justice, Boulder: Paradigm, 1-15. The ordinary people of Japan were kept from the information of the crimes committed by their imperial army abroad while heavily exposed to the pains and sacrifices of war, especially the catastrophic outcomes of atom bombs dropped on Hiroshima and Nagasaki. Thus they developed the identity of the victim rather than that of a perpetrator or aggressor. This is the last position most Korean and Chinese citizens would take. In this context, the communication approach suggested by Han is an attempt to get out of the trap of antagonism led by politicians in terms of national interests and open up a cosmopolitan horizon of mutual understanding at the level of civil society. All factors considered, Han thinks that the current dilemma may find a threshold to solution when the USA became a partner in transitional justice, reflecting on the war crimes and sacrifices for which she is also responsible as Japan is.
