In "Good Prose: The Art of Nonfiction," author Tracy Kidder emphasizes the introspective nature of the essay form, aligning it with the thoughts of philosopher Michel de Montaigne. Montaigne suggests that true understanding of one's thoughts is challenging; if one were entirely sure of their beliefs, they would produce definitive decisions rather than exploratory essays. This highlights the essence of essays as a means of navigating and unraveling complex ideas rather than simply stating conclusions.

Kidder's work illustrates that essays are not just vehicles for established opinions but serve as tools for reflection and discovery. Montaigne’s quote encapsulates this concept, revealing the beauty and necessity of questioning and contemplating thoughts. Good prose emerges from this exploration, allowing writers to engage with their uncertainties and share the journey of their intellectual pursuits with readers.
