Early 20th Century (1896-1959) · Logical Empiricism, Philosophy of Language
Friedrich Waismann was an Austrian mathematician and philosopher, a key member of the Vienna Circle who worked closely with Ludwig Wittgenstein and Moritz Schlick. He is best known for his contributions to logical empiricism and the philosophy of language, particularly his concepts of 'open texture' and 'language strata'. His later work moved toward a more flexible, descriptive approach to language and meaning.
