Age of Enlightenment(redirected from 18th-century philosophy)
Age of Enlightenmentthe period of intellectual ferment leading up to the French Revolution, which was distinguished by a fundamental questioning of traditional modes of thought and social organization, and sought to replace these with an exclusive reliance on human reason in determining social practices. Many thinkers and philosophers were associated with these developments, amongst them Voltaire (1694-1778), MONTESQUIEU, Holbach (1723-89), Helvétius (1715-71), Diderot (1713-84) and ROUSSEAU. Nor was the movement merely confined to France; it also embraced numerous other thinkers elsewhere, including members of the so-called SCOTTISH ENLIGHTENMENT, such as Adam FERGUSON and John MILLAR, whose work was especially sociological. Despite a common accord on the importance of reason in human affairs, major differences of view existed between thinkers: Voltaire popularized English liberal doctrines of NATURAL RIGHTS; Holbach and Helvétius took these doctrines further and argued for UTILITARIANISM and representative government; while Rousseau's concept of the SOCIAL CONTRACT led to holistic conceptions of state and society realized in the French Revolution. In retrospect, much Enlightenment thought is seen as superficial, lacking an adequate empirical research base, and above all overconfident about human PROGRESS and the ultimate triumph of Reason. However, the Enlightenment era signalled a final decisive break between traditional and modern thought, and between traditional and modern forms of social organization.
