　　1．________

　　On the train from New York to Boston, I found next to me sat an elderly blind gentleman．My PhD director was a blind man, so I started a talk with him．To my enjoyment, the blind man was a good talker, so we shared a happy and interesting journey．It was then a time when a racial conflict broke out in Los Angeles, so our topic turned to the racial prejudice．

　　2．________

　　The old man told me he was born in the South and that he was brought up to believe black people were a lower race．In the South he had never gone to dinner or school with black people．Their family had used black servants．

　　Then he went to school in the north．Once his class appointed him to organize a picnic．He went so far as to attach to the invitation the message “We reserve the right to refuse anyone”．In the South it means “Negroes are not welcome”．This aroused a huge row in the class, and their form teacher dealt him a severe scolding．He went on．Sometimes when he happened to be served by a black assistant in a shop, he would place the money on the counter for the black man to take so as to avoid hand-to-hand contact．I asked, smiling, “So you wouldn't marry a person of colour?” He said laughingly, “I shut myself off from them, let alone marry a black woman．Truth to tell, at that time I thought any white person who married a black person would bring shame upon their parents．”

　　4．________

　　During his graduate years in Boston he was caught in a car accident．He was lucky enough to survive, but he lost his sight, unable to see anything．He was admitted to Carroll Center for the Blind, where he learned to read Braille, walk with the aid of a stick and other skills．Gradually he came to live on his own．“What worried me most was that I couldn't make out the colours of the people around．I went to a psychological counselor and told my problem to him．He helped me a lot and won my complete trust so that I was willing to tell everything to him．One day he told me he himself was black．” After that, his prejudice was thoroughly gone．He couldn't tell whether the counselor was white or black but he knew he was a good man．The colour of skin meant nothing to him．

　　When the train was pulling into the station, the old man stood up and said, “I've lost my sight and also prejudice-What a fortunate thing!” His wife was already on the platform．As soon as the old man got off, the couple threw themselves into each other's arms．To my surprise, his wife was an old black lady! I had a sudden insight：Eyes often mislead and even cheat us while an eyeless man is sometimes lucky, because he has to “look” at the world with mind's eye; what eye views may be one-sided and incomplete while what mind's eye views is always the true nature．
