Instead of representing the ideas of the eighteenth century through the eyes of a few outstanding writers, Dr Mackrell has tried to reconstitute the intellectual climate of the from the works of largely unknown historians, jurists, economists and others. In this way he illuminates the rich texture of eighteenth-century French thought, without which the ideas of Voltaire, Montesquieu and even Rousseau lose much of their meaning. This study breathes life into the fierce controversies that shook the Age of Reason long before the outbreak of Revolution.
