“The premier philosopher of the radical Enlightenment, whose metaphysics of nature and pioneer defense of secular democracy laid the foundations of modern thought.”
Baruch (Benedict) de Spinoza (1632–1677) was a Portuguese-Jewish philosopher born in Amsterdam. Educated in the Keter Torah academy of the Spanish-Portuguese Sephardic community, Spinoza came to reject traditional theological conceptions of a transcendent, personal deity, miracles, and the divine authorship of scripture. Excommunicated by the Amsterdam rabbinic court in 1656, he lived quietly as a lens grinder while producing Ethics and the Theological-Political Treatise—works that inaugurated modern biblical criticism and constitutional democracy.
Western metaphysics was constrained by Cartesian substance dualism and theological scholasticism, subordinating philosophical inquiry to ecclesiastical and biblical dogma.
Pioneered radical philosophical monism (Deus sive Natura / God or Nature), founded modern biblical textual criticism, and constructed the philosophical architecture of secular democracy and freedom of conscience.
Catalyzed the Radical Enlightenment, inspiring German Idealism (Hegel, Schelling), romanticism (Goethe), modern secular biblical scholarship, and liberal constitutional principles.
