Introduction

Age of Enlightenment, a term used to describe the trends in thought and letters in Europe and the American colonies during the 18th century prior to the French Revolution (1789-1799). The phrase was frequently employed by writers of the period itself, convinced that they were emerging from centuries of darkness and ignorance into a new age enlightened by reason, science, and a respect for humanity. The period also often is referred to as the Age of Reason.
