Arguably the most decisive shift in the history of ideas in modern times was the complete demolition during the late 17th and 18th 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 justification 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 18th century, the origins and rise of the Radical Enlightenment have been little studied doubtless largely because of its very wide international sweep and the obvious difficulty of fitting it 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.
