Spinoza and the Dutch Radical Enlightenment
Baruch Spinoza (1632–1677) was the Dutch Jewish philosopher who, working within the unprecedented intellectual freedom of the Dutch Republic, produced the most radical philosophical system of the 17th century, arguing that God and Nature are identical (pantheism/panentheism), that the Bible is a human document subject to rational criticism, that democratic governance is the most rational political system, and that human freedom consists in acting from reason rather than passion, making him the foundational figure of Enlightenment rationalism, biblical criticism, and modern secular liberalism.
Spinoza's radicalism was only possible in Amsterdam. Expelled from the Jewish community (1656, the most extreme cherem on record) for views that threatened the community's accommodation with Dutch authorities, he nonetheless lived, wrote, and published in Amsterdam because the Dutch Republic's commercial tolerance extended even to ideas that horrified orthodox Protestants, Catholics, and Jews alike. No other European state in 1670 would have permitted the publication of the Tractatus Theologico-Politicus, the first systematic argument for freedom of thought and expression as necessary conditions for good governance.
The Tractatus Theologico-Politicus (1670) made three explosive arguments: that the Bible was written by multiple human authors in specific historical contexts (the founding text of modern biblical criticism and historical-critical method); that prophecy is imagination, not divine communication (eliminating the supernatural foundation of religious authority); and that freedom of thought and expression does not threaten but is the necessary condition for a stable, rational state (the Enlightenment case for liberalism). His posthumous Ethics (1677) built the philosophical system: God is not a personal creator separate from the universe but the infinite substance of which everything is a mode, matter and mind are two attributes of the same underlying reality.
Predictive History's analysis: the Dutch Golden Age is the first instantiation of the middle-class, commercially tolerant, intellectually free civilization type that defines modernity. Spinoza is the thinker who articulates why that civilization works: freedom of thought produces better reasoning, better reasoning produces better governance, better governance produces commercial success and social stability. The toleration that felt merely pragmatic to Amsterdam's merchants was, in Spinoza's analysis, the philosophical foundation of civilization.
