In this sentence, option “education” is the correct one as the Enlightenment Era was known as the Era of Reason since it was believed that reason was a very valuable human capacity that could break free from ignorance. Enlightenment philosophers believed that by learning and studying, people would develop critical thinking guided by reason. During this era, emphasis was made on universal education, scientific method, breakdown between church and state and liberty. The Enlightenment took place in late 17th and early 18th century and it started in Europe mainly to defy those institutions with great power at the time such as the Catholic Church and monarchies. Among the great philosophers that advocated this movement were John Locke, Adam Smith, Voltaire, Immanuel Kant, Isaac Newton and Thomas Jefferson.
