In "Lonesome Dove," the protagonist reflects on men who have tragically taken their own lives. He contemplates the reasons behind such despair, suggesting that a lack of appreciation for the simple beauties of the world, like the sky and the moon, might lead to overwhelming sadness. This notion indicates a deep understanding of human emotions and struggles.

His insights suggest that happiness can often be found in the natural world, but for some, that connection is insufficient to combat feelings of hopelessness. The contemplation of these themes highlights the complexities of life and the importance of finding joy in the little things, which can serve as a lifeline in difficult times.
