The term "vulgarity" in literature has long been used to mark the boundary between what is considered refined and what is seen as crude or unrefined, often carrying moral as well as aesthetic implications. Some authors, like Chekhov and Wilde, depict vulgarity as a trait both inherent in certain behaviors and symptomatic of wider social attitudes—for example, its association with coarse language or ill-mannered conduct ([1], [2], [3], [4]). In other works, it is invoked to critique not merely personal affectation but the general decline of taste and intellectual rigor, as seen in Schopenhauer’s and Nietzsche’s reflections on a culture stifled by mediocrity and the suppression of genuine creativity ([5], [6], [7], [8]). Meanwhile, writers like Hartley and Emerson use the term to comment on how ostentation in dress or conduct can cross the line from acceptable to distastefully common, highlighting its role as a subtle marker of class and refinement ([9], [10], [11]). Across these diverse examples, vulgarity emerges not just as a descriptor of lowbrow behavior, but as a multifaceted concept that reflects the tensions between societal standards, individual expression, and cultural decay.
