In P.G. Wodehouse's work, the metaphor of a moth desiring a star illustrates the futility of longing for something unattainable. The moth, representing individuals who aspire for lofty goals, often finds itself yearning for a brilliance that is beyond reach. This tragic desire highlights the gap between one's aspirations and reality, emphasizing the struggle between ambition and the limitations of one's circumstances.

Wodehouse also notes that even the most practical individuals can become distracted by these lofty goals, leading them to lose sight of their true place in life. The allure of the 'star' symbolizes ideals or dreams that can inspire, yet also overwhelm those who chase them. This insight serves as a cautionary reflection on human nature and the often unfulfilled pursuit of our desires.
