“Mr. Wittgenstein is concerned with the conditions for a logically perfect language – not that any language is logically perfect, or that we believe ourselves capable, here and now, of constructing a logically perfect language, but that the whole function of language is to have meaning, and it only fulfills this function in proportion as it approaches to the ideal language which we postulate.“ (Bertrand Russell: Introduction. In: Tractatus Logico-Philosophicus. Logisch-philosophische Abhandlung by Ludwig Wittgenstein. First published by Kegan Paul London 1922.)
