The Arts and Entertainment offer a multitude of ways for people to express themselves, from escapism to education to catharsis to cerebral engagement. They often hit on themes the human brain was shaped to react deeply to in order to survive and function in a social world. These include murders, backstabbing and other such themes that the brain was shaped to understand in order to cope with the reality of being human.
Where did the word Entertaiment come from?
The word comes from the Latin intertenere, which means to hold inside. This is a good fit, since the purpose of the entertainment industry is to stimulate our minds and uplift our moods.
