can you please explain the traditional and western values themes?

This is perhaps the most conspicuous theme in the play. It initially seems like Soyinka is setting a clear dichotomy between these two things, tradition embodied by Baroka and modernity embodied by Lakunle. However, as the play progresses Soyinka defies the audience's assumptions. Lakunle espouses a variety of backwards views and seems to abandon his progressive principles when it is convenient to do so. Similarly, Baroka says he does not hate progress but merely finds its sameness and stagnation boring. He is preparing to use a stamp machine to make the village make money as they do in Lagos. Soyinka thus suggests that progress is not bad, but that it must be done on African terms.
