‘Randstad’, the region made up by Amsterdam, Utrecht, Rotterdam and The Hague, in the Dutch Republic. But the timetable has also shifted. According to accepted wisdom in Enlightenment historiography, the radical phase of the movement only occurred in the second half of the eighteenth century, just prior to the French Revolution. But as Israel points out, time and again, its radicalism was there from the beginning in the Spinozist circles of the Dutch Republic. Jonathan Israel was not the first to focus on the importance of the Dutch Republic. American historians such as Margaret Jacob and a host of Dutch researchers such as Wim Klever, Theo Verbeek and Wiep van Bunge already had published widely on the subject, but his work easily surpasses theirs in scope.
Jonathan Israel's well written books are not just the specialist's fare. He made the Spinozist Enlightenment into a history that matters, a history that is politically relevant, as in his view the early radical Enlightenment already embodied all decisive elements of modern democratic, secular and tolerant society. No wonder that his work has also found large audiences outside the circles of Enlightenment historians, especially in Western Europe where as a result of large-scale immigration politicians, philosophers and citizens alike are forced to rethink and even reinvent the society they live in. For many of them Jonathan Israel's Enlightenment exemplifies the will to transform the world through ideas and politics, a mission we all need to contribute to if we want to keep the Enlightenment as the quintessence of Western liberal thought alive.
Great books almost automatically become the subject of great debates and Jonathan Israel's work is no exception. The more so as he seeks debate, enjoys it and thrives on it. We therefore decided that we could honour his work best by inviting a few Dutch historians to comment on parts of his work. Wiep van Bunge of the Erasmus University of Rotterdam focused on issues related to the first volume of the Enlightenment trilogy, Joris van Eijnatten of the Free University of Amsterdam questioned some central themes of Enlightenment Contested and Wyger Velema examined Jonathan Israel's work on Dutch political patriotism in the second half of the 18th century. Jonathan Israel responded to these criticisms in ‘Toleration, Spinoza's “realism” and Patriot modernity: replying to Van Eijnatten, Van Bunge and Velema’. Before the Dutch commentators got the floor, Jonathan Israel delivered the A.H. Heineken lecture 2008, the privilege of those awarded the prize: ‘Equality and Inequality in the late Enlightenment’.
I want to thank the editors of De Achttiende Eeuw for their willingness to accommodate the papers of this colloquium.
