The philosophes in the 18th century were French intellectuals whose ideas formed the core of Enlightenment though. The principal figures involved were Montesquieu, Voltaire, Denis Diderot, Jean Jacques Rousseau, Condillac, Alembert,D'holbach, Turgot, and Condorcet.


They did not form any sort of organization, but often discussed and debated ideas among themselves. They shared a devotion to reason, philosophical empiricism, mathematical modes of thought, trust in scientific inquiry, and a belief in the Idea of Progress. They had a wide following among the intellectuals of Europe. Their zest for rational investigation of the natural world is exemplified by Diderot's ‘Encyclopedie (1751-66), to which many of them contributed.

In religion the philosophes encouraged toleration and skepticism; in politics their writings often reflected and furthered republicanism and the democratic spirit.

The American Founding Fathers read their work closely and adopted many of their ideas. Montesquieu in particular influenced American republicanism. In turn they followed American events, often with the personal encouragement of Benjamin Franklin and admired the American Revolution

The philosophes had a great influence on the French Revolution. The doctrines of natural law which they helped to popularize, were codified in the French Declaration of the Rights of Man and of the Citizen (1789) and in the American Bill of Rights (1791).
