Dutch writer and physician whose works reflect his lifelong search for a social and ethical philosophy.

Eeden studied medicine at Amsterdam and, with writers Willem Kloos and Albert Verwey, founded (1885) De nieuwe gids, a literary periodical devoted to modern authors and new social ideas. Later he practiced medicine at Bussum, near Hilversum, where he started a clinic for physical therapy. In 1898 he founded Walden, an agricultural colony based on the ideas of Thoreau. Van Eeden's personality was many-sided, essentially ethical in outlook, having affinities with Tolstoy. After much doubt and disappointment, he joined the Roman Catholic Church in 1922.

Although in his early days van Eeden was chiefly known outside his own country for his idealistic social theories, his fame is based on his literary work. He first attracted attention with De kleine Johannes (1885; The Quest, 1907), a symbolic fairy tale. Het lied van schijn en wezen (“Song of Semblance and Substance”), the first part of which appeared in 1895, is a long philosophical poem. His psychiatric experience provided material for the novel Van de koele meren des doods (1900; The Deeps of Deliverance, 1902). Van Eeden's criticism and social treatises were collected in Studies, 6 vol. (1890–1918). He also wrote many plays and translated Rabindranath Tagore's work into Dutch.
