|Intensions: intensions are reference objects resulting from a linguistic description, in contrast to the material objects (extensions) that may differ therefrom, whether due to inaccuracies, or by the use of indexical expressions. Examples of intensions are “the oldest person in the room”, “the winner”, “John's favorite quote”, “the one who violates the speed limit”. See also morning star/evening star, extensionality, extension._____________Annotation: The above characterizations of concepts are neither definitions nor exhausting presentations of problems related to them.
