In Taiwan, most of the studies on Tan Ssu-Tong have been focused on his general thoughts and philosophy; few unfortunately have examined his ideas on education. In Mainland China, papers on his thoughts about education have been found to mislead, to miss the core of his thoughts, because of the researchers' narrow point of view. This study tries to reanalyse and revaluate his ideas of education basing research on "The Chronology of Tan Ssu-Tong" and "The Anthology of Tan Ssu-Tong", in the hope of getting a more complete picture of his thoughts on education. Tan Ssu-Tong was born at a crucial moment in the nation's history. His thoughts on education are characterized by their mixture of Chinese traditional thoughts and modern western thoughts. They also result from the philosophical concepts of I-Tai theory (以太說 ), Hsin-Li theory (心力論 ) and Tsung-ch'ueh-wang-luo theory (總決網羅論 ). Besides, he believed the aim of education is the development of abilities to preserve the country, the race and the culture of China. He firmly believes that education is an essensial factor to the nation's survival. Accordingly, he proposes reform in the school system and the civil service examination systems. Nevertheless, he puts much more emphasis on the development of social education than the reversions of traditional school systems. He often emphasizes the necessity of social education using learned societies, newspapers and magazines. His educational thoughts not only includes the reversions of traditional system, but also make great efforts to create an innovative system. His thoughts are a valuable thinking and action model, to which modern educationalists should pay more attention.
