Frege favors 2 identity is a relation between names or signs. The difference is unaccountable if identity is a relation between objects since both statements alike would only record the fact that some thing is the same as itself. It seems that something is learned from an identity statement because it is learned through the difference of the two names, hence, what the statement really tells us about is a relation between names.

Outline and Assess Frege's two solutions to Frege's Puzzle During the course of this essay I intend to explicate Frege's puzzle regarding the semantics of identical proper names as .

In modern times, Frege's insight has been defended with elaborate modal logical arguments, beginning with Barcan in , using Leibniz's Law about identity and indiscernibility, that seem to suggest that for any a and b, if a = b (even contingently), then necessarily a = b.

Frege's puzzles are puzzles about the semantics of proper names, although related puzzles also arise in the case of indexicals. Gottlob Frege (–) introduced the puzzle at the beginning of his article "Über Sinn und Bedeutung" (" On Sense and Reference ") in in one of the most influential articles in analytic philosophy and.
