Extremely elegant idea-driven science fiction. Turns out I'd read several of these before - "Story of Your Life" after seeing Arrival, but longer ago also "Division by Zero" (a mathematician proves that arithmetic as a formal system is inconsistent, with an existential cost for her and a human one with her husband), "Hell Is the Absence of God" (what loving God would mean in a world in which His existence was incontrovertibly manifest, visitations of angels, souls visibly departing for Heaven or Hell upon death, even glimpses of Hell itself through regular turning transparent of the ground) and "Liking What You See: A Documentary" (a scientific procedure is developed which can prevent people from perceiving or responding to physical appearance and beauty) - but all of them, both previously read and new, reward careful attention.
