Harper Lee develops her main themes--primarily those of
racism, intolerance and loss of innocence--through the two main plots of To
Kill a Mockingbird. The first main plot is established in Chapter 1 with the
introduction of the mysterious Boo Radley, and the children's interest in him continues
to grow for most of Part One. In Part Two, the Tom Robinson trial takes central focus
for the first dozen chapters before the main focus returns to Boo Radley in the final
four chapters. Primarily through Scout and these two characters--Boo and Tom--are most
of the themes developed. The children slowly learn the meaning of tolerance as they
change their attitudes about Boo: He goes from being a scary ghoul who prowls the
neighborhood at night to a lonely man in search of friendship (once the children realize
that he is the source of the gifts in the secret knothole). The approaching trial of Tom
Robinson teaches them about the attitudes of the town, and then the children get to see
for themselves how justice is served when an accused black man goes before an all-white
jury. Loss of innocence is evident in both Boo and Tom, but it is the children who
are the main focus of this theme. By the end of the novel, they have seen some major
events unfold before them, and nearly all of them are
troubling.
