In "The March of Folly: From Troy to Vietnam," Barbara W. Tuchman explores the theme of folly in history, examining how leaders pursue ideas that seem irrational or counterproductive. Tuchman uses Burke's principle, asserting that for an idea to hold value, it must be grounded in common sense and lead to practical outcomes. This perspective emphasizes the importance of practicality and rationality in decision-making processes, warning against folly that disregards these principles. The quote reflects the essence of Burke's argument, advocating for a critical evaluation of ideas based on their usefulness and common sense. Tuchman illustrates various historical instances where folly prevails over wisdom, encouraging readers to analyze the motivations behind such decisions. Through this examination, she underscores the need for a pragmatic approach in governance and leadership, urging future generations to learn from past mistakes.
