Jonathan Irvine Israel (born 26 January 1946) is a British writer and academic specialising in Dutch history, the Age of Enlightenment and European Jews. Israel was appointed as Andrew W. Mellon Professor in the School of Historical Studies at the Institute for Advanced Study, Princeton, New Jersey, in January 2001 and retired in July 2016. He was previously Professor of Dutch History and Institutions at the University College London. In recent years, Israel has focused his attention on a multi-volume history of the Age of Enlightenment. He contrasts two camps. The "radical Enlightenment" was founded on a rationalist materialism first articulated by Spinoza. Standing in opposition was a "moderate Enlightenment" which he sees as weakened by its belief in God. Life Israel's career until 2001 unfolded in British academia. He attended Kilburn Grammar School, and like his school peer and future fellow historian Robert Wistrich went on to study History as an undergraduate at Queens' College, Cambridge, graduating with a first-class degree in Part II of the Tripos in 1967. His graduate work took place at the University of Oxford and the El Colegio de México, Mexico City, leading to his D.Phil. from Oxford in 1972. He was named Sir James Knott Research Fellow at the University of Newcastle upon Tyne in 1970, and in 1972 he moved to the University of Hull where he was first an assistant lecturer then a lecturer in Early Modern Europe. In 1974 he became a lecturer in Early Modern European History at University College London, progressing to become a reader in Modern History in 1981, and then to Professor of Dutch History and Institutions in 1984. In January 2001, Israel became a professor of modern European history in the School of Historical Studies at the Institute for Advanced Study, Princeton, New Jersey. In 2007, the 375th anniversary of the birth of Spinoza, he held the Spinoza Chair of Philosophy at the University of Amsterdam. Works Israel has defined what he considers to be the "Radical Enlightenment," arguing it originated with Spinoza. He argues in great detail that Spinoza "and Spinozism were in fact the intellectual backbone of the European Radical Enlightenment everywhere, not only in the Netherlands, Germany, France, Italy, and Scandinavia but also Britain and Ireland", and that the Radical Enlightenment, leaning towards religious skepticism and republican government, leads on to the modern liberal-democratic state. Israel is sharply critical of Jean-Paul Marat
