The Fall claims that power and subjugation are necessary in the world. Only authority can absolutely determine truth in an uncertain world. In the case of the novel’s narrator, power is derived by judging others, and by taking a God-like stance of authority over them. Power is also tied to physical location, and manifests in geographical summits. For example, to live on a mountain is to be above others, and therefore to have power over them. Lastly, just as judging others yields power, so does forgiving them. This is the only way to place yourself above those who appear as authority figures.
Jean-Baptiste fails in his attempt to gain power over his listener in The Fall. But it is through this failure that Camus establishes his own authorial control over the reader.
