What is an example of epiphany from Book 1 (not Chapter 1) of Cry, the Beloved Country?

There are all kinds of moments of insight, large and
small, in the first book of this novel.  As Stephen travels around Johannesburg and
meets new people, he is constantly struck by new thoughts of people and what they think
and believe.  One of the most important ideas of this novel is the state of white and
black relations in South Africa in the mid-20th century.  The white population of South
Africa is approximately 20% of the people, while the black native people make up the
other 80%, but the white people have most, if not all, of the political and economic
control of the country, and the growing discontent of the native people is a growing
concern.

Stephen is not a radical thinker or a trying to
rouse the black population to action like his brother is, but he is not immune to the
situation.  He makes a great statement in Chapter 5 that serves as a great epiphany for
the entire novel thematically.  He says to his friend, Msimangu, that "it is not in my
heart to hate a white man.  It was the white man who brought my father out of
darkness."  But in the process, the white man broke the tribe.  "The tragedy is not that
things are broken.  The tragedy is that they are not mended again."  He criticizes both
the people who break things and the people who sit by seeing the fact of things being
broken.

He would clearly like to see a change where the
society can be mended, but his epiphany is that "They [the white society] are afraid . .
. it is fear that rules this land."  Like any situation that would require the status
quo to change, fear is present.  No one likes change--especially people who have the
most to lose in the change.  The white people of South Africa had much to lose if they
allow blacks to have more say in the way things are in this country, and so they do
everything they can to control the black population.  Interestingly, Paton wrote and
published this novel shortly before apartheid became the law of the land, and the white
population was able to maintain an iron-fisted control for another 50 years before
things changed.
