When philosophers use a word—"knowledge", "being", "object", "I", "proposition", "name"—and try to grasp the essence of the thing, one must always ask oneself: is the word ever actually used in this way in the language-game which is its original home?—What we do is to bring words back from their metaphysical to their everyday use. You say to me: "You understand this expression, don't you? Well then—I am using it in the sense you are familiar with."— As if the sense were an atmosphere accompanying the word, which it carried with it into every kind of application.
