“Like the humanists of antiquity—such as Socrates and the Stoics—most of the Enlightenment philosophers had an unshakable faith in human reason. This was so characteristic that the French Enlightenment is often called the Age of Reason. The new natural sciences had revealed that nature was subject to reason. Now the Enlightenment philosophers saw it as their duty to lay a foundation for morals, religion, and ethics in accordance with man’s immutable reason. This led to the enlightenment movement.”
