This study examines Itō Jinsai’s 伊藤仁斎 (1627–1705) criticisms of the Great Learning (C: Daxue 大學 J: Daigaku). Three primary sources are considered: Jinsai’s Shigi sakumon 私擬策問 (Personal Essays, 1668); the Daigaku teihon 大學定本 (The Definitive Text of the Great Learning, manuscript 1685); and his essay, “Daigaku wa Kōshi no isho ni arazaru no ben” 大學非孔氏之遺書辨 (The Great Learning is not a Writing Confucius Transmitted, 1705), appended to his Gomō jigi 語孟字義. The study suggests that Jinsai’s critical inclinations grew from his (...) acceptance of Zhu Xi’s views about the value of doubt for progress in learning. The study also suggests that Jinsai’s thinking on the Great Learning had political implications derived in many respects from Jinsai’s overall approach to philosophizing via analysis of words and their meanings.
