Yu Hyeong-won (; 1622–1673), also spelled as Yoo Hyung-Won, was a Korean philosopher. His art name was Ban'gye (磻溪). He was a Neo-Confucianist and science scholar of the Korean Joseon Dynasty. He was a Korean pioneer of the early silhak ("practical learning") school[1] [2] as well as a social critic and scholar of the late Joseon period. He was the disciple of Misu Heo Mok and second cousin of the silhak scholar Seongho Yi Ik.
Yu was a member of the Munhwa Yu clan, and many of his extended family members held high official positions in the Joseon government.[3] [4] However, he did not become an official, but led the life of a reclusive scholar. His work, Bangyesurok, became influential during the reign of King Yeongjo, who was made aware of it in 1741 and authorised its printing in 1770.[5]
