The Dutch Legacy investigates the political philosophy and philosophy of religion of Franciscus van den Enden, Lodewijk Meyer, the brothers De la Court, and Adriaan Koerbagh in order to assess their contributions to the development of radical movements in the Enlightenment.

While Spinoza’s impact on the early Enlightenment has always found due attention of historians of philosophy, several 17th-century Dutch thinkers who were active before Spinoza’s Tractatus theologico-politicus was published have been largely neglected: in particular Spinoza’s teacher, Franciscus van den Enden (Vrye Politijke Stellingen, 1665), Johan and Pieter de la Court (Consideratien van Staet, 1660, Politike discoursen, 1662), Lodewijk Meyer (Philosophia S. Scripturae Interpres, 1666), the anonymous De Jure Ecclesiasticorum (1665), and Adriaan Koerbagh (Een Bloemhof van allerley lieflijkheyd, 1668, Een Ligt schynende in duystere plaatsen, 1668). The articles of this volume focus on their political philosophy as well as their philosophy of religion in order to assess their contributions to the development of radical movements (republicanism / anti-monarchism, critique of religion, atheism) in the Enlightenment.

A biography of the boldest and most unsettling of the early modern philosophers, Spinoza, which examines the man's life, relationships, writings, and career, while also forcing us to rethink how we previously understood Spinoza's reception in his own time and in the years following his death. The boldest and most unsettling of the major early modern philosophers, Spinoza, had a much greater, if often concealed, impact on the international intellectual scene and on the early Enlightenment than philosophers, historians, and political theorists have conventionally tended to recognize. Europe-wide efforts to prevent the reading public and university students learning about Spinoza, the man and his work, in the years immediately after his death in 1677, dominated much of his early reception owing to the revolutionary implications of his thought for philosophy, religion, practical ethics and lifestyle, Bible criticism, and political theory. Nevertheless, contrary to what has sometimes been maintained, his general impact was immediate, very widespread, and profound. One of the main objectives of the book is to show how early and how deeply Leibniz, Bayle, Arnauld, Henry More, Anne Conway, Richard Baxter, Robert Boyle, Henry Oldenburg, Pierre-Daniel Huet, Richard Simon, and Nicholas Steno, among many others, were affected by and led to wrestle with his principal ideas. There have been surprisingly few biographies of Spinoza, given his fundamental importance in intellectual history and history of philosophy, Bible criticism, and political thought. Jonathan I. Israel has written a biography which provides more detail and context about Spinoza's life, family, writings, circle of friends, highly unusual career and networking, and early reception than its predecessors. Weaving the circumstances of his life and thought into a detailed biography has also led to several notable instances of nuancing or revising our notions of how to interpret certain of his assertions and philosophical claims, and how to understand the complex international reaction to his work during his life-time and in the years immediately following his death.

In Adam Boreel (1602-1665): A Collegiant’s Attempt to Reform Christianity, Francesco Quatrini offers an account of the life and thought of Adam Boreel, a leading member of the seventeenth-century Collegiant movement in Amsterdam.

During the second half of the seventeenth century the entire intellectual framework of educated Europe underwent a radical transformation. A secularized view of humanity and nature was replacing faith in the direct operation of God's will in the temporal world, while a growing confidence in human reason and the Scientific Revolution turned back the epistemological skepticism spawned by the Reformation. By focusing on the Dutch Collegiants, a radical Protestant group that flourished in Holland from 1620 to 1690, Andrew Fix explicates the mechanisms at work in this crucial intellectual transition from traditional to modern European worldview. Starting from Rijnsburg, near Leiden, the Collegiants spread over the course of the century to every major Dutch city. At the same time, their thinking evolved from a millenarian spiritualism influenced heavily by the sixteenth-century Radical Reformation to a philosophical rationalism similar to the ideas of Spinoza. Fix has taken on an important topic in the history of ideas: the circumstances under which natural reason came to be accepted as an autonomous source of truth for the individual conscience. He also has fresh and concrete things to say about the relationship between religion and science in early modern European history. Originally published in 1990. The Princeton Legacy Library uses the latest print-on-demand technology to again make available previously out-of-print books from the distinguished backlist of Princeton University Press. These editions preserve the original texts of these important books while presenting them in durable paperback and hardcover editions. The goal of the Princeton Legacy Library is to vastly increase access to the rich scholarly heritage found in the thousands of books published by Princeton University Press since its founding in 1905.

The Enlightenment that Failed explores the growing rift between those Enlightenment trends and initiatives that appealed exclusively to elites and those aspiring to enlighten all of society by raising mankind's awareness, freedoms, and educational level generally. Jonathan I. Israel explains why the democratic and radical secularizing tendency of the Western Enlightenment, after gaining some notable successes during the revolutionary era (1775-1820) in numerous countries, especially in Europe, North America, and Spanish America, ultimately failed. He argues that a populist, Robespierriste tendency, sharply at odds with democratic values and freedom of expression, gained an ideological advantage in France, and that the negative reaction this generally provoked caused a more general anti-Enlightenment reaction, a surging anti-intellectualism combined with forms of religious revival that largely undermined the longings of the deprived, underprivileged, and disadvantaged, and ended by helping, albeit often unwittingly, conservative anti-Enlightenment ideologies to dominate the scene. The Enlightenment that Failed relates both the American and the French revolutions to the Enlightenment in a markedly different fashion from how this is usually done, showing how both great revolutions were fundamentally split between bitterly opposed and utterly incompatible ideological tendencies. Radical Enlightenment, which had been an effective ideological challenge to the prevailing monarchical-aristocratic status quo, was weakened, then almost entirely derailed and displaced from the Western consciousness, in the 1830s and 1840s by the rise of Marxism and other forms of socialism.

Arguably the most decisive shift in the history of ideas in modern times was the complete demolition during the late seventeenth and eighteenth centuries - in the wake of the Scientific Revolution - of traditional structures of authority, scientific thought, and belief by the new philosophy and the philosophes, culminating in Voltaire, Diderot, and Rousseau. In this revolutionary process which effectively overthrew all justicfication for monarchy, aristocracy, and ecclesiastical power, as well as man's dominance over woman, theological dominance of education, and slavery, substituting the modern principles of equality, democracy, and universality, the Radical Enlightenment played a crucially important part. Despite the present day interest in the revolutions of the late eighteenth century, the origins and rise of the Radical Enlightenment have been astonishingly little studied doubtless largely because of its very wide international sweep and the obvious difficulty of fitting in into the restrictive conventions of 'national history' which until recently tended to dominate all historiography. The greatest obstacle to the Radical Enlightenment finding its proper place in modern historical writing is simply that it was not French, British, German, Italian, Jewish or Dutch, but all of these at the same time. In this novel interpretation of the Radical Enlightenment down to La Mettie and Diderot, two of its key exponents, particular stress is placed on the pivotal role of Spinoza and the widespread underground international philosophical movement known before 1750 as Spinozism.
