Abstract:Both Nietzsche's Superman Theory,a theory for value reconstruction,and Lizhi's Childlike In- nocence Theory,adopt the metaphor of child to criticize the traditional moral values.The value trend of the two theories are both the return to the newborn baby,the trend to the superman (the grown - up).And neither of the two philosophers escapes the objective presence of the traditional thinking,so that they are both contrary to their own theories.
