歐陽厚均（1766-1846），字福田，號坦齋，湖南安仁縣人。早年「負笈麓山，從羅慎齋夫子游」，後掌教嶽麓書院凡二十七載，教育學生以「誠」為本，並強調「以學治道、經世致用」，培植曾國藩、左宗棠等眾多人才，為清嶽麓書院四大山長之一。歐陽厚均治學以《易》為宗，其易學思想延續湖湘學派「經世致用」之學風，認為「《易》之為書，原以致用，且隨人、隨時、隨事皆可用」，反對泥於象數，而不切於人。故《易鑑》一書，薈萃諸家之說，並援史事藉古鑑今，以顯窮經致用之旨。本文旨在探討歐陽厚均引史證《易》之特色，扼要敘述其生平、學術淵源、釋《易》之法與易學思想，望本文之作，有俾於學者認識歐陽厚均及其《易鑑》之全貌

OuYang-HouJyun (1766-1846) was born in Anren County, Hunan province. During the Ching dynasty, he was one of the four deans running Yuelu Academy (嶽麓 書院) for 27 years. His principle of education is mainly based on ＂honesty＂, and emphasizes the notion of ＂governing studying of very practical use＂. He was the master of many famous Ching dynasty officials, such as Zeng Guofan(曾國藩) and Tso ZhongTang (左宗棠). ＂The Book of Changes＂ is the basis for OuYang-HouJyun's teaching, and he especially emphasizes the idea of ＂governing studying of very practical use＂. Such theory is the legacy fromHuxiang School. The scholars of Huxiang School all held the opinion that ＂The Book of Changes＂ has the adaptive feature, which is whenever, wherever and whoever suitable for practical use. They oppose to be simply limited by the meaning of signs. This thesis is mainly to discuss the ideas presented above, and hopefully this thesis will be the key-stone for future researches
