This quote from P.G. Wodehouse's "Performing Flea" reveals a sense of futility in communication when confronting deeply ingrained beliefs. It suggests that no amount of reasoning or persuasion can shift opinions that are firmly established in society. The author implies that significant, perhaps radical, measures are required to challenge and change such thoughts, hinting at the difficulty of altering public perception.

Wodehouse's insight highlights the struggle individuals face when attempting to influence social or cultural ideas. The metaphor of needing "dynamite" emphasizes that conventional discourse is often insufficient for overcoming stubborn mindsets, urging readers to consider more impactful approaches to effecting change. This resonates strongly with the challenges of communication in a world where misinformation and preconceptions often prevail.
