Frege, Russell, and Analytic Philosophy of Language
The Birth of Philosophy of Language → Russell: Theory of Descriptions → Early Wittgenstein: “Tractatus Logico-Philosophicus”
Gottlob Frege (1848–1925) is the “father of analytic philosophy” and modern logic. His central question: how can mathematical statements (“2+2=4”) be necessarily true and not accidental? The answer required developing formal logic and a theory of meaning.
Frege introduced the distinction between sense (Sinn) and reference (Bedeutung) of an expression. The reference is the object to which the expression refers. The sense is the way in which this object is presented. “The Morning Star” and “The Evening Star” have the same reference (the planet Venus...
This distinction solves many philosophical puzzles: how can statements about non-existent objects be true? (“The present king of France is bald”—this sentence has sense, but no reference). How do proper names work in reports of opinions? (“She thinks that Hesperus is a star”—replacing Hesperus wi...
Bertrand Russell (1872–1970) in “On Denoting” (1905) proposed a revolutionary solution to the problem of names and descriptions—one of the most elegant ideas in analytic philosophy.
