What we call “understanding a sentence” has, in many cases, a much greater similarity to understanding a musical theme than we might be inclined to think. But I don't mean that understanding a musical theme is more like the picture which one tends to make oneself of understanding a sentence; but rather that this picture is wrong, and that understanding a sentence is much more like what really happens when we understand a tune than at first sight appears. For understanding a sentence, “we say”, || one says, points to a reality outside the sentence || language. Whereas one might say, “Understanding a sentence means getting hold of its content; and the content of the sentence is in the sentence”.
