Overview
The French Enlightenment applied critical reason to religion, government, and society, seeking to replace inherited authority with principles that could withstand rational scrutiny. Voltaire attacked religious intolerance and the abuses of church and crown, Diderot and d'Alembert's Encyclopédie gathered and disseminated secular knowledge, and Rousseau and Montesquieu reimagined the foundations of political legitimacy.
Key ideas
- Reason and Criticism: Every institution — religious, political, social — must justify itself before the tribunal of reason rather than rest on tradition or revealed authority alone.
- Religious Toleration: Voltaire's campaigns against intolerance and judicial abuse argued that liberty of conscience is a precondition of a just society, not a threat to it.
- The Encyclopédie: Diderot and d'Alembert's vast collaborative project aimed to compile and popularize human knowledge, treating the spread of reason itself as an engine of progress.
