Spinoza developed a rigorous monist philosophy of nature, mind, affects, religion, and politics that recast freedom as understanding necessity.
Intellectual setting
Spinoza wrote after the Dutch Republic's religious conflicts and scientific transformations, drawing on Cartesian vocabulary while confronting questions of scriptural authority and civic liberty.
Key ideas
One substance
God or Nature is the single infinite substance of which finite things are modes, rather than a transcendent creator outside the world.
Freedom through understanding
Human liberation involves adequate ideas and active affects that lessen passive bondage to confused causal forces.
Legacy
His work influenced Enlightenment debates, biblical criticism, German idealism, political theory, and modern naturalism, while provoking condemnation in his own lifetime.
