The third schools of neo-Confucianism took consideration into the real intentions of original texts by Confucius and Mencius. Yamaga Sokō established his philosophy on Confucian ethics, and assumed the samurai to be the highest class. Itō Jinsai paid attention to "ren" of Confucius and he respected "ren" as the love for another person and "truth" as pure consideration. In addition, deriving from his substantial studies of ancient Chinese classics, Ogyū Sorai insisted that the original Confucian spirit is to rule the world and to save a citizen.
