His earliest major published work was an ethno-historical study of modern and medieval Thailand. He then became interested in the comparative study of the ways Western categories of magic, science and religion have been used by anthropologists to make sense of other cultures which do not use this three-part system. After the outbreak of civil war in Sri Lanka, he began to study the role of competing religious and ethnic identities in that country. At Harvard, he trained several generations of anthropologists in a number of fields. He also served on the National Research Council's Committee for International Conflict Resolution.[3] He did field research on the Organisation of Buddhist temples in Sri Lanka (Monks, Priests and Peasants, a Study of Buddhism and Social Structure in Central Ceylon and several papers in the American Anthropologists and the Journal of Asian Studies).[5]
Awards
In November 1997, Tambiah received the prestigious Balzan Prize[3] for "penetrating social-anthropological analysis of the fundamental problems of ethnic violence in South East Asia and original studies on the dynamics of Buddhist societies [that] have opened the way to an innovative and rigorous social-anthropological approach to the internal dynamics of different civilizations".[6]
A month later, the Royal Anthropological Institute of Great Britain and Ireland awarded him its highest recognition,[7]
the Huxley Memorial Medal and Lecture.[8]
In September 1998, he was awarded the Fukuoka Asian Culture Prize by the city of Fukuoka, capital of Fukuoka Prefecture, Japan.[9]
