Throughout literary history, "sloth" has served as a multifaceted symbol—ranging from a metaphor for moral decay to a tangible depiction of physical laziness. In many classical and early modern works, it is depicted as a vice that underpins poverty and societal downfall, as evidenced by its association with ruin in Thomas Jefferson's pronouncements [1, 2] and proverbial maxims that link sloth to the key of poverty [3, 4, 5, 6]. Philosophers and essayists such as Montaigne and Cicero further intertwine sloth with other vices, suggesting that neglect and idleness can erode both personal virtue and communal values [7, 8, 9, 10, 11]. On the other hand, in narrative fiction, writers like H. G. Wells use the term not only to characterize human failings, but also to animate non-human creatures—imbuing them with a slow, almost lethargic quality as seen in his depiction of various sloth-like beings [12, 13, 14, 15, 16, 17, 18, 19]. Even in poetic expressions, such as those found in Homer's epics and Victor Hugo's verses, sloth becomes a lens through which contrasts between dynamic heroism and idle despondency are drawn [20, 21, 22]. Thus, across genres and eras, "sloth" emerges as a potent literary device—a symbol of lethargy that embodies not only inaction but also a broader commentary on human nature and societal decline.
