Literary notes about OBSTACLE (AI summary)
Writers employ the term "obstacle" to evoke both a tangible barrier and a metaphor for internal or societal impediments. In some works, such as those by Edgar Allan Poe ([1]) and Jules Verne ([2]), the term describes physical blockades that challenge the characters’ progress or resolve, whether it is the hard resistance encountered in a moment of violence or a barrier that must be blown up in pursuit of an adventure. Meanwhile, authors like Elizabeth Gaskell ([3]) and Leo Tolstoy ([4]) use it to signify setbacks in personal ambition or social aims, illustrating how obstacles can inhibit growth or shift the course of events. Additionally, the term is often invoked to represent abstract challenges—ranging from commercial difficulties ([5]) to interpersonal conflicts ([6]), and even as obstacles that, once overcome, strengthen an individual’s determination as in narratives of persistent progress.
