Pre-Socratic Discrete Kinematics

We present a neglected heterodox version of Zeno’s paradox of the Stadium, underlining some problems that a discrete kinematics would have to account for. Building on our reconstruction of the Stadium argument we provide new arguments to show that a discrete kinematics cannot uphold three independently plausible assumptions about motion, that we label No Switching, Granular Continuity and Different Velocities, and hence it should drop at least one.
