Kaibara Ekken
Japanese Confucianist Philosopher, Pre-Linnaean botanist, physician (1630-1714)
Kaibara Ekken (貝原 益軒; December 17, 1630 – October 5, 1714) or Ekiken, also known as Atsunobu (篤信), was a Japanese Neo-Confucianist philosopher and botanist.
Kaibara was born into a family of advisors to the daimyō of Fukuoka Domain in Chikuzen Province (modern-day Fukuoka Prefecture). He accompanied his father to Edo in 1648, and was sent in 1649 to Nagasaki to study Western science. At his father's urging, he continued his studies in Nagasaki as a rōnin from 1650 through 1656. He then re-entered service to Kuroda, which led to his continuing studies in Kyoto. After his father's death in 1665, he returned to Fukuoka.
Kaibara's two most significant contributions to Japanese culture were the study of nature based on a blend of Western natural science and Neo-Confucianism, and the translation of the complex writings of Neo-Confucianism into vernacular Japanese. His synthesis of Confucian ideas and Western science influence the formation of Shinto, especially State Shinto, and reflect similar concerns to the Kokugaku movement.
Kaibara's science was confined to Botany and Materia medica and focused on the "natural law". Kaibara became as famous in Japan as people such as Charles Darwin when it came to science.

A concise life account rarely captures disputed attribution, private networks or the changing language used to describe a career. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
