Kaibara Ekiken was an Edo period writer, Confucian scholar, educator, herbalist and physician.
He was the fifth son of Kaibara Kansai, a samurai in the service of Kuroda Mitsuyuki, lord of Fukuoka han. Ekiken traveled to Kyoto to study, and returned to Fukuoka in 1664.
Ekiken was originally a student of Wang Yangming's brand of neo-Confucianism, but turned to following the teachings of Zhu Xi years later; late in his life, he had questions and doubts about Zhu Xi's teachings, and compiled these into a text titled Taigiroku (大疑録, lit. "Great Doubts Record").
