Philosophical Investigations
Ludwig Wittgenstein Original title Philosophische Untersuchungen (German, 1953)

Philosophical Investigations is a work by the philosopher Ludwig Wittgenstein. The book was published posthumously in 1953. Wittgenstein discusses numerous problems and puzzles in the fields of semantics, logic, philosophy of mathematics, philosophy of psychology, philosophy of action, and philosophy of mind, putting forth the view that conceptual confusions surrounding language use are at the root of most philosophical problems. Wittgenstein alleges that the problems are traceable to a set of related assumptions about the nature of language, which themselves presuppose a particular conception of the essence of language. This conception is considered and ultimately rejected for being too general; that is, as an essentialist account of the nature of language it is simply too narrow to be able to account for the variety of things we do with language. This view can be seen to contradict or discard much of what he argued in his earlier work Tractatus Logico-Philosophicus .

“For a large class of cases — though not for all — in which we employ the word meaning it can be explained thus: the meaning of a word is its use in the language.”

§ 43, this has often been quoted as simply: The meaning of a word is its use in the language.
