|What are the "humanities"? Try to give an "intensional" definition and an "extensional" definition.|
Intensional definition: Defining something by its essential characteristics. E.g., A chair is a seat for one person having a back.
Extensional definition: Defining something by naming the members of the class. E.g., in North America, the "Great Lakes" refers to the Lakes Superior, Michigan, Huron, Erie, and Ontario.
