The term "irreligious" in literature is employed with multifaceted nuance, often serving as a sharp critique or a marker of unconventional attitudes toward established religious norms. In some works, such as Dante’s depiction of moral decay ("for who more irreligious is than he" [1]), the term underscores a problematic inversion of piety, while Oscar Wilde’s characters casually brand ideas or individuals as irreligious to underscore their deviation from respectable propriety ([2], [3]). In the realm of modern skepticism, figures like William James incorporate "irreligious" among traits of a materialistic and empiricist worldview ([4], [5]), suggesting that irreligiosity might connote a rational—but perhaps cold—rejection of traditional faith. Moreover, when used in political or societal contexts, as in Webster’s analysis of a Republic ([6]) or in critiques of clerical conduct by Chesterton ([7]), the word reinforces both alienation from and a subversive challenge to institutional religious authority. Thus, across these literary examples, "irreligious" emerges as a versatile term, oscillating between moral indictment and intellectual self-positioning.
