Craft is the more prominent feature of literary art than inspiration.
Inspiration is a necessity, while craft is a tool. Viewing other peoples work does nothing more than assist a writer by teaching him a variety of rhetorical devices, and new diction. Inspiration is the motivation behind writing. One cannot scribe without motivation, therefore one cannot write without inspiration. Viewing others work is not a necessity, and if you describe it as such, then I query - How does reading another work motivate one to write? If a writer should find motivation through another literary devices than the writer is inspired by their aspiration for knowledge, and by the knowledge that the separate author has provided for them. Without inspiration one cannot write, and if one cannot write then his talent will rapidly decay. Craft is purely a tool used by an eager writer to improve, but is not a necessity.
