How is the theme of the novel repeated in the last paragraph of this chapter?

This paragraph repeats the novel's main theme, the end of a culture. Throughout the novel, but more so in these last chapters we see the final destruction of the Igbo way of life. Their religion is threatened, the tribesmen have lost their self-determination, and the very center of their community is threatened. Okonkwo's grief is almost catchy because the reader comes to sympathize with the Igbo and their plight, but the majority of the tribe has come to the point where they seem ready to move on. On the other hand, there are those like Okonkwo, who simply want to hold onto their identity.

"Okonkwo was deeply grieved. And it was not just a personal grief. He mourned for the clan, which he saw breaking up and falling apart, and he mourned for the warlike men of Umuofia, who had so unaccountably become soft like women."
