Philosopher
Kaibara Ekken
1630–1714
Japanese Neo-Confucian, physician and naturalist whose Record of Great Doubts set out one of the most systematic philosophies of doubt in early modern Japan.

Kaibara Ekken remained a professed Neo-Confucian all his life, yet gave early modern Japan one of its most thorough philosophies of doubt. His interests were wide: his Plants of Japan is a study of Japan’s medicinal plants and herbs.
The Great Learning for Women, a curriculum for women’s education, has traditionally been attributed to him.
Key ideas
- Great doubts
- Ekken’s Record of Great Doubts records his doubts about Zhu Xi’s teachings. He opened it with Lu Xiangshan’s saying that a learner should worry when he has no doubts, since those without doubts make no progress.
- Doubt as a waypoint
- Scepticism was never an end in itself: doubt was a stage on the way to firmer conclusions and to well-informed engagement with the world.
- Nourishing life
- His Instructions for Cultivating Life stressed nourishing one’s generative force (ki) in harmony with that of everything between heaven and earth.
