The Enlightenment

The Enlightenment (also known as the Age of Enlightenment) was an intellectual and philosophical movement that was very vast with it's ideas in Europe during the 18th century, "The Century of Philosophy". The Enlightenment included a range of ideas centered on reason as the primary source of authority and legitimacy and came to advance ideals like liberty, progress, tolerance, fraternity, constitutional government and separation of church and state (or religion and law). In France, the central doctrines of the Enlightenment philosophers were individual liberty and religious tolerance, in opposition to an absolute monarchy and the fixed dogmas of the Roman Catholic Church. The Enlightenment was marked by an emphasis on the scientific method and reductionism, along with increased questioning of religious orthodoxy—an attitude captured by the phrase Sapere aude, "Dare to know".
