Died
21 February 1677, The Hague
Education
Amsterdam Jewish community school; then self-taught (Descartes, Latin)
Fields
Metaphysics, ethics, political philosophy, biblical criticism

Dutch philosopher born into a Portuguese-Jewish family. In 1656 he was excommunicated from Amsterdam's Jewish community for heretical views, and he went on to live simply, grinding lenses and devoting himself to philosophy. In 1673 he turned down a professorship at Heidelberg to protect his freedom of thought.

His masterpiece, the Ethics, is built like Euclid's geometry — definitions, axioms, propositions — and was published after his death. His view of God and Nature as one substance was long condemned as atheism, but went on to shape German idealism and the modern scientific worldview.

Big ideas

God, or Nature (Deus sive Natura)There's only one substance. Call it God or Nature — same thing. Thought and extension are two of its attributes.
Freedom is understanding necessityEverything happens by necessity. People think they're free only because they don't know the causes of their actions. Real freedom comes from understanding that necessity.
Freedom from the passionsThe more clearly you understand the causes of your emotions, the less they push you around and the more active you become.

If you think like them…

If you're like Spinoza, you see everything as linked in chains of cause and effect. Rather than sliding into nihilism, you look for calm and freedom in understanding that necessity. You tend to try to understand why people act the way they do rather than rushing to blame them.
