In Things Fall Apart, the arrival of the missionaries best illustrate the struggle between tradition and change.
While many resist the changes the missionaries bring, many like them. The missionaries bring new goods to the village and export village goods, bringing money into the village. This trade, however, has its drawbacks. Meanwhile, conversation between village elders and Mr. Brown allows them to understand one another. Mr. Brown tries to encourage the elders to educate their children, explaining this will bring hope for their futures.
Although many welcome these changes, others -- including Okonkwo -- are resistant. He and a few others do not like this change and even openly resist it. They value their traditions and do not want them altered.
