The word "moderation" in literature has been employed to convey balance, restraint, and a well-measured approach to various aspects of life—ranging from personal conduct and political governance to emotional expression and aesthetic appreciation. It is often depicted as a virtue and an essential quality, as seen when it is praised as “as definite as perfection” in Chesterton's reflection [1] and when it is associated with the calm wisdom of happy temperaments in La Rochefoucauld’s maxims [2]. Yet, literature also highlights its limits, suggesting that excessive moderation can sometimes lead to a lack of passion or idealism, as noted in the writings of Nietzsche and Dostoyevsky [3, 4]. In both classical and modern texts—from Diogenes Laertius’s admiration of Solon’s measured judgments [5] to Edith Wharton’s nuanced character portraits in which moderation modulates tone and impact [6]—this term functions as a critical benchmark for judging behavior, art, and society.
