Inoue was instrumental in bridging Eastern and Western philosophical traditions. His primary reference work, A Dictionary of Philosophy, underwent revisions in 1884 and 1912 following its original 1881 release. Beyond lexicography, he served as a professor at Toyo University and maintained a rigorous output of lectures and texts, acting as a prominent promoter of bushido ideology in Japan for nearly fifty years.
Political Stance and State Ideology
Inoue utilized his platform to advocate for the Japanese state, most notably through his commentary on the Imperial Rescript on Education. He encouraged public support for imperialism and the state, a position that placed him in opposition to proponents of international education like Shimonaka Yasaburo, Noguchi Entaro, and Izumi Tetsu. His political influence was formalized through his membership in the House of Peers and his active participation in the International Education Movement.
Views on Religion and Legacy
In his writings, Inoue asserted that Christianity remained fundamentally incompatible with the theocratic, polytheistic polity of Japan. He labeled followers of the faith as disloyal to the nation. His contributions were formally recognized by the state through his induction into the Imperial Academy and the receipt of the Order of the Sacred Treasure, 2nd Class. He died in 1944 at Koishikawa-ku and was interred at Zōshigaya Cemetery.
