ILL> the Roman philosopher, Seneca, wrote a letter to his friend: “my wife has a ignorant child, who has suddenly became blind. What I am about to tell you will be difficult to believe, but is true. We cannot make her understand that she has become blind and no change in her environment will help her. She insists that her nurse take her to a house where it is not dark. It seems to me,” continued the philosopher, “that what has happened to her is happening to all of us. Not one of realises he is blind.”
