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.
