|Morning Star/Evening Star: Example for intensions from G. Frege's Über Sinn und Bedeutung (1982). The extension would be the planet Venus. Intensions may cause difficulties in relation to so called opaque contexts. E.g. a whitness maintains that she has seen the morning star. She may then not be quoted as having seen the evening star - while both are identical to the Venus. See also opacity, identity, intensions._____________Annotation: The above characterizations of concepts are neither definitions nor exhausting presentations of problems related to them.
