Symbolism in Harper Lee's To Kill A Mockingbird "I'd rather you shoot at tin cans in the backyard, but I know you'll go after birds. Shoot all the bluejays you want , if you can hit 'em, but remember it's a sin to kill a mockingbird." This is what Atticus Finch tells his children after they are given air-rifles for Christmas. Uniquely, the title of the classic novel by Harper Lee, To Kill A Mockingbird, was taken from this passage. At first glance, one may wonder why Harper Lee decided to name her book after what seems to be a rather insignificant excerpt. After careful study, however, one begins to see that this is just another example of symbolism in the novel.
