DecadenceThe word decadence, which at first meant simply "decline" in an abstract sense, is now most often used to refer to a perceived decay in standards, morals, dignity, religious faith, honour, discipline, or skill at governing among the members of the elite of a very large social structure, such as an empire or nation state. By extension, it may refer to a decline in art, literature, science, technology, and work ethics, or (very loosely) to self-indulgent behavior.
Decadent movementThe Decadent movement (Fr. décadence, "decay") was a late-19th-century artistic and literary movement, centered in Western Europe, that followed an aesthetic ideology of excess and artificiality. The Decadent movement first flourished in France and then spread throughout Europe and to the United States. The movement was characterized by a belief in the superiority of human fantasy and aesthetic hedonism over logic and the natural world.
