 Jinsai’s emphasis on semantic etymology and philological instruction was meant to offset Buddhist training and presuppositions: he wanted his students to recognize the difference between Buddhist terms with their various nuances and those of Confucianism. In particular Jinsai was offended to see so many seemingly Buddhist terms in Neo-Confucian discourse. In an attempt to rid such terms from Neo-Confucianism, Jinsai took great pains to document the heterodox lineages of words so that they could be eliminated from Neo-Confucian writings.
