In chapter IV, Dostoevsky offers up the solution to the problems the
main players in the novel. Throughout all of part V, what has been the main
issue among the characters is pride. Even after realizing that his engagement
is irreparably harmed, Luzhin’s pride won’t let him just give up until he has
exhausted all of his abilities. Katerina Ivanovna’s pride won’t let her resign
herself to poverty and she spends the money Rodka gave her on material items.
Even Lebezyatnikov has too much hubris to just be a good person and goes on
about popular intellectual ideas and ethics. Finally, in chapter IV, Rodka
confesses to Sonya and recognizes that it was his pride making him strive for
extraordinariness, thus making him unextraordinary. It is Rodka’s next step in returning
to society as he has now made this connection with Sonya. Sonya is the only
character without pride or hubris because it is a sin. While Dostoevsky is not
promoting that everyone should turn to religion, he is still arguing that pride
and hubris are the instruments of self-destruction, no more evident than
Katerina Ivanovna literally dying while still touting her nobility earlier in
part V.
Dostoevsky also uses part V to denounce popular intellectual movements
as nothing more than fads. Lebezyatnikov is the human representation of these
movements, and Dostoevsky spares no ink in making Lebezyatnikov look like a
pompous fool. For Dostoevsky, these intellectual movements are nothing more
than adventures in self-servitude and elevating oneself above others. And that
hubris and pride has destructive consequences.
