But any profound work all inevitably is complex and many Yuan, "Earth Gives birth to a boy" is not exceptional. In the book has also contained the very many symbolic meaning very thick ingredient and massive carefully enters the micro psychological description. Perhaps is Floyd's influence, Wright also is put in the creation more attentions on to in the character morbid psychology analysis and the description, but this kind of psychology, also is in fact carries on the heartless dissection to oneself a process. The black the varying degree has had the metamorphosis psychology under the long-term visible invisible pressure, they or like other standard the mother such sincerely believes the religion, in order to anaesthetizes oneself; Or likes by other standard in the sweetheart which escapes on the way kills 蓓 west is been same, borrows the ethyl alcohol to anaesthetize oneself; Or is equally timid like uncle tom to the oppressor, is resigned to bad conditions. Wright dares honestly to face directly own innermost feelings, through own took a specimen and puts to the microscope under carries on the careful observation, then infers the entire black nationality. Just like in the book said "enlarges other standard psychology 12 million times, is entire black's psychological". In order to express the author to the race between the difference profound understanding, Wright has utilized the massive symbolic image. For example "Bai" and "black" striking contrast. Starts in the novel, other standard and the partner play one kind to imitate the Caucasian words and deeds manner the game, unfolds is piece of "extends in other standard eye and towers in front of them in sunlight giant Caucasian world"; Drives to the others when sees white small hand; Employer Ms. Dalton entire is the white spirit which was blind; When reporter inquired when who is a murderer, even the company hires the host family big Bai Maodu to jump all of a sudden to on other standard shoulder indicates and confirm him; Other standard the time which is arrested faced with 8,000 Caucasians' surrounding at present also is a vast whiteness piece of heavy snow... ... In the book the "Bai" image already became one kind to be intense relatively with "black" includes the concrete content the stiffly concept, constituted a powerful unfeeling implementation racial segregation and the oppression Caucasian society, was precisely this omnipresent "Bai" world suffers is oppressing other standard, urged him to take risks, steps onto the murder the path. Again concerns to the "blind" symbol also very much has the profound meaning. The Dalton husbands and wives very are all good to the black surface on, sympathize with them, donate money for them, work for them with the opportunity. But they had not certainly understood makes black this kind of condition the true reason is any. They may donate money but contribute all are come from to exploit black's soaring income, they actually are not willing to hire the small advantage and the good house to the black but no matter what they live are being easy to initiate the crime the dirty crowded area. The Caucasians have the intense race prejudice and the benefit, they do the good only is for comfort the oneself day by day restless soul and attempts with this to alleviate black's hatred mood. Ms. Dalton is a in every sense of the term blind person, Mary and warm-hearted Caucasian attorney Mike Si all did not understand other standard the real idea, the black leaders care only is own ballot... ... Similarly has satire meaning is, black's revolt similarly also is blind. Other standard has killed the innocent Caucasian woman is an example. Other standard also continuously is at 象征性 "失语 the" condition, he is unable to catch own real idea and to perform to express, he has the speech which duplicates repeatedly is "they has not seen me, I not to see their". This all sorts lacked the exchange blindness to cause a curtain tragedy occurrence
