With any work of literature, reflections have to be generated by the reader. There is little in terms of external forces that can provide "a reflection." At the same time, there might be "the" reflection present as much as multiple reflections present. Bearing this in mind, I would suggest that you could look at a couple of areas to assist you here. The first would be the issues of prejudice and tolerance that are raised through the novel. Can a nation predicated upon the idea of "justice for all" permit discrimination in any form to enter its social and political realm? The work does a stellar job in making discrimination and inequality a moral and political issue. Reflecting on these ideas might be able to render much in terms of the value of the work. Another realm would be to reflect on characters themselves. How about Atticus? Reflecting on his courage, his strength, and his commitment to both private good and public interest could provide much to you in your reflection. Are Atticus' values and conceptions lived out to their fullest today? Where could we use a figure like Atticus in our social order? Again, a reflection is personal and driven by introspective thought about a particular work. With this work, there can be much in way of reflective merit.
"To Kill a Mockingbird" has a specific reflection that was created by the writer. The writer, Harper Lee, tells the story of two men. One man, Tom Robinson, is on trial for raping a white girl. He is innocent as it was her father who beat and raped her. The other man is a man named Boo Radley. Yet, he is convicted of the crime. Boo is a simple minded recluse. He is scared of people and hides away, but he is an innocent good person. Scout and her brother Jem are saved by him from Mr. Ewell. Harper Lee uses the symbol of the mockingbird to get the reader, through Scout's, the little girl in the story, to symbolize the twio men. The reflection occurs as Scout looks back on the events surrounding the two men, the men's innocence, and compares them to the mockingbird that harms no one but gives forth a beautiful song. The mocking bird also mocks other birds just as the children had initially mocked Boo Radley and the justice system was a mockery when it came to Tom's trial.
