FATHER: But don't you see that the whole trouble lies here. In words, words. Each one of has within him a whole world of things, each man of us his own special world. And how can we ever come to an understanding if I put in the words I utter the sense and value of things as I see them; while you who listen to me must inevitably translate them according to the conception of things each one of you has within himself. We think we understand each other, but we never really do. (page 10, Dover ed.)
