That illusion of a world so shaped that it echoes every groan, of human beings so tied together by common needs and fears that a twitch at one wrist jerks another, where however strange your experience other people have had it too, where however far you travel in your own mind someone has been there before you - - is all an illusion. We do not know our own souls, let alone the souls of others. Human beings do not go hand in hand the whole stretch of the way. There is a virgin forest in each; a snowfield where even the print of birds' feet is unknown. Here we go alone, and like it better so. Always to have sympathy, always to be accompanied, always to be understood would be intolerable.
