The philosopher who is known for devising the "Stadium" argument is Zeno of Elea. Zeno was a Greek philosopher who lived in the 5th century BC and was a member of the Eleatic school of philosophy, which was founded by Parmenides. Zeno is famous for his paradoxes, which were intended to challenge the idea of motion and the concept of change.

One of Zeno's paradoxes, known as the "Stadium," involves a group of runners who are all running at the same speed around a track. Zeno argued that if the runners are all moving at the same speed, and the track is divided into equal sections, then each runner should be at the same distance from the start and finish line at any given time. However, this seems to contradict the fact that the runners are in motion and are covering different distances as they run around the track. This paradox was intended to challenge the concept of motion and change, and it has been the subject of much discussion and debate among philosophers and scientists.
