In literature, the word "unfeigned" is employed to underscore a profound authenticity and sincerity in emotions and actions. For instance, authors use it to highlight genuine feelings—such as the unmistakable, heartfelt joy in Lewis Carroll’s work ([1]) or the honest surprise in both Dickens ([2]) and Bret Harte ([3]). It is equally effective in conveying reluctant acceptance or hesitation, as seen in Richard Wagner’s depiction ([4]), and in emphasizing sincere admiration or respect, echoed in works by Arthur Conan Doyle ([5]) and Jane Austen ([6]). Across diverse genres—from Dostoyevsky’s vivid portrayals of inner turmoil ([7], [8]) to the spiritual context in Thomas à Kempis’ writing ([9])—"unfeigned" consistently serves to mark moments free of pretense, capturing the true, raw essence of human experience.
