" Like the positivists, Wittgenstein was hostile to metaphysics. But he attacked metaphysics not with a blunt instrument like the verification principle, but by the careful drawing of distinctions that enable him to disentangle the mixture of truism and nonsense within metaphysical systems. ‘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 which is its original home? What we do is to bring words back from their metaphysical to their everyday use’ (PI I, 116). "
