In "Fear and Loathing on the Campaign Trail '72," Hunter S. Thompson reflects on the subjective nature of humor and its significance in understanding one's mental state. He acknowledges that his views on humor as a key indicator of sanity might not resonate with everyone, suggesting that perspectives on what is humorous can vary greatly among individuals. This highlights the personal and often complex nature of humor. Thompson also points out the challenge of assessing someone's sense of humor, as it is deeply rooted in personal experience and individual perception. The quote emphasizes that while humor can be a window into one's psyche, it remains an intimate and private aspect of human experience, leaving room for uncertainty about its universal implications.
