Most research on Vietnamese philosophy is conducted by modern Vietnamese scholars. The traditional Vietnamese philosophy has been described by one biographer of Ho Chi Minh (Brocheux, 2007) as a "perennial Sino-Vietnamese philosophy" blending different strands of Confucianism with Buddhism and Taoism. Some researchers have found the empirical evidence of this "blending" and defined the socio-cultural phenomenon as "cultural additivity". Another, Catholic, writer (Vu, 1966) has analysed Vietnamese philosophy as constituted of tam tài ("three body" Heaven, Man, Earth) philosophy, yin-yangmetaphysics, and agricultural philosophy. Tran Van Doan, professor of philosophy at National Taiwan University (1996) considers that Vietnamese philosophy is humanistic but not anthropocentric.
The confucian poet-philosopher-scholar is typified by Lê Quý Đôn. Other confucianists include Chu Văn An (1292–1370) mandarin, Lê Quát a 14th Century anti-Buddhist Confucian writer, Mạc Đĩnh Chi (1280–1350), Nguyễn Trãi (1380–1442) a famous Đại Việt Confucian scholar, Nguyễn Khuyến (1835-1909). Notable modern Vietnamese philosophers include Cao Xuân Huy (vi, 1900-1983), Nguyễn Duy Quý (vi, 1932-), Nguyễn Đức Bình (vi, 1927-), Nguyễn Đăng Thục (vi, 1909-1999), Phạm Công Thiện (vi, 1941-2011), Trần Văn Giàu (vi, 1911–2010), modern marxist philosopher Trần Đức Thảo (noted in Paris in the 1960s) and Vietnamese Catholic philosopher Lương Kim Định.
