Precision and Real Decisions

Medicine runs into the Sorites paradox at the edges of life itself. At what week does a fetus become viable? Survival odds rise gradually with each passing day, yet hospitals and laws need a fixed cutoff to act on. The threshold is necessary and arbitrary at the same time.
