 Heterodox thinkers such as Jinsai and Sorai often challenged orthodox Neo-Confucians on matters related to the texts elevated for study. Jinsai in particular affirmed that the most important works for students were the Analects of Confucius and the Mencius. Distancing himself considerably from the orthodox position, Jinsai offered a series of arguments seeking to prove, on textual and philosophical grounds, that the Great Learning was not a Confucian text. While he admitted that there was value in the study of the ancient classics, Jinsai believed that the Analects and Mencius were by and large sufficient for meaningful education.
