Enlightenment is a European intellectual movement of the 17th and 18th centuries in which ideas concerning God, reason, nature, and humanity were synthesized into a worldview that gained wide assent in the West and that instigated revolutionary developments in art, philosophy, and politics.
Central to Enlightenment thought were the use and celebration of reason, the power by which humans understand the universe and improve their own condition.
The goals of rational humanity were considered to be knowledge, freedom, and happiness.
