In P.G. Wodehouse's "My Man Jeeves," the narrator reflects on a friend who, despite appearing foolish at times, possesses a hidden layer of intelligence. This interesting dynamic suggests that beneath the surface, there are depths to his character that are not readily accessible. The narrator implies that while this intelligence is occasionally evident, it is not easily drawn out.

The comparison to needing "dynamite" to access this inner sense emphasizes the difficulty in reaching that insightful part of his friend. It highlights the complexity of people, who may exhibit folly on the surface yet hold deeper intelligence within them. This observation serves as a commentary on human nature and the challenges of understanding others fully.
