Summary

Dutch philosopher who developed a rigorous geometric metaphysics in which God and Nature are identical — the single infinite substance with infinite attributes — and derived a naturalistic ethics and liberal political theory.

Core Contribution

God or Nature (Deus sive Natura) is the single infinite substance; mind and matter are two of infinite attributes; everything follows necessarily from God's nature. Human bondage: we are enslaved by passive emotions; freedom comes through intellectual understanding which produces active emotions aligned with reason. Criticized biblical authorship and defended democracy.

Key Spikes & Highlights

Was excommunicated (cherem) from the Amsterdam Jewish community at 23 with unusually harsh language — the grounds are unknown, but his pantheism and biblical criticism are the likely cause.
Argued that every finite thing strives to persist in its own being (conatus) — this self-preservation drive is not a defect but the foundation of all value and motivation.
Lived as a lens-grinder, refusing academic positions and wealthy patrons in order to maintain philosophical independence — died at 44, probably from inhaling glass dust.
