In literature, the term "disbeliever" has been used to highlight a character's or speaker's skepticism, often serving as a subtle yet powerful marker of intellectual or emotional doubt. For instance, in William James' analysis, the term is invoked to point out the limited internal clarity possessed by those who refuse to believe in certain matters, thus emphasizing the inherent uncertainty of human understanding [1]. Meanwhile, in the annals of dramatic literature such as John Webster's work, "disbeliever" appears as a concise identifier—almost like a stage note—suggesting an underlying mistrust or critical stance that colors the unfolding narrative [2]. Through these varied applications, the word "disbeliever" enriches the text by inviting readers to examine the complexities of belief and skepticism within different literary contexts.
