Overview
Baruch (Benedictus) Spinoza (1632–1677) was a Dutch philosopher of Portuguese-Jewish descent who developed a rigorous geometric metaphysics of God-or-Nature. Excommunicated from Amsterdam’s Jewish community in 1656, he ground lenses and wrote in Latin with a small circle of freethinkers. The Ethics and Theological-Political Treatise argue for intellectual love of God and freedom of philosophizing. Handbook dates: 1632–1677. He became early modern rationalism’s most radical systematizer.
Main ideas
There is one substance—God or Nature—with infinite attributes; mind and body are parallel expressions, not interacting substances. Everything follows from divine necessity; freedom is understanding necessity, not uncaused will. Affects are explained geometrically; inadequate ideas yield bondage, adequate ideas yield blessedness. Scripture teaches obedience and piety; reason teaches truth—hermeneutics must not confuse them. Democracy and freedom of judgment best preserve peace. Conatus—the striving to persevere—structures psychology and politics.
