Burke, Michael B.2016-02-182016-02-182000The Modern Schoolman 78 (1): 1-8.https://hdl.handle.net/1805/8360The “staccato run,” in which a runner stops infinitely often while running from one point to another, is a prototype of the “superfeat” (or "supertask”), that is, a feat involving the completion in a finite time of an infinite sequence of distinct, physically individuated acts. There is no widely accepted demonstration that superfeats are impossible logically, but I argue here, contra Grunbaüm, that they are impossible dynamically. Specifically, I show that the staccato run is excluded by Newton’s three laws of motion, when those laws are supplemented with a certain defensible philosophical judgment.ensupertaskssuperfeatsinfinityspacetimeZeno's paradoxesArticle
