王通，字仲淹，王通是隋代的大儒，諡號曰「文中子」。其傳世作品為《中說》，《中說》一書中所闡述之理念實以儒家思想為依歸。王通頗有弘道淑世之心，意欲以其學做為應世之用，故而著重儒學當中的務實效益。王通之學在中晚唐以來漸次受到儒者注意，宋朝初年一度成為顯學。王通學說當中，既關注到《易》乘時變轉之特質，且論及到《易》的道德與踐履意義，並將「中道」與《易》相嵌合，從兩線論述《易》之「中道」，一線：從居下卦中位的二爻與居上卦中位的五爻處談「中道」。二線：從道德恆常處談「中道」，其云：「千變萬化，吾常守中焉。」要之，本文以王通《中說》當中的易學觀念做為探討對象，期以析論「中道」思想、在易學上的發揚進路，以及隋代以降儒學變古肇端之呈現
