Answer: The Enlightenment, commonly referred to as the Age of Reason, was an intellectual and cultural movement that promoted science over blind faith and reason over superstition in the eighteenth century. Enlightenment philosophers like John Locke, Isaac Newton, and Voltaire challenged conventional wisdom and disseminated novel concepts about inquiry, openness, and religious tolerance throughout Europe and the Americas by using the power of the press. Many believe that the Enlightenment marked a significant turning point in Western culture, ushering in an era of light in place of an earlier one. Enlightenment philosophy was dominated by a number of concepts, such as rationality, empiricism, progressiveness, and cosmopolitanism.
