The document summarizes major Enlightenment ideas and thinkers. During the Enlightenment, philosophers such as Thomas Hobbes, John Locke, Jean-Jacques Rousseau, Denis Diderot, Voltaire, Baron de Montesquieu, and Adam Smith developed new ideas that differed from previous beliefs. They advocated for concepts like natural rights, social contracts, separation of church and state, freedom of speech and religion, and laissez-faire economics. These Enlightenment thinkers helped spread new philosophical perspectives that challenged absolute rule and promoted individual liberties.
