 Jinsai and Sorai both criticized the Neo-Confucian metaphysical notion of principle, stating that rather than a word with ancient, and therefore legitimate, Confucian origins, ri was a term that had derived in part from Daoist and Buddhist discourse and so was often wrongly construed in Neo-Confucian discussions out of ignorance of, or disregard for, the sanctity of the original teachings of Confucianism. Jinsai’s standard on this count was supposedly the lexicon of the Analects and Mencius, while Sorai’s was the more ancient Six Classics. Despite their disagreements on the level of antiquity that should be considered as the source of legitimate philosophical discourse, both agreed that principle was a problematic part of it and so should not be naively highlighted in metaphysical discussions.
