Summary

In this lecture, Graham Priest discusses Zeno’s paradoxes of motion, focusing on the paradox of the arrow. He provides historical context, explaining that Zeno’s arguments were intended to defend Parmenides’ view that change is illusory by showing that change leads to contradictions. Priest outlines the dichotomy paradox and the arrow paradox, emphasizing the latter as the most profound. He explains the standard mathematical solution proposed by Russell, which relies on the concept of instantaneous velocity and the idea that motion is a function of position over time. However, Priest raises objections to this solution, arguing that it does not fully resolve the intuitive problem of change. He then introduces his preferred dialetheist solution, inspired by Hegel, which accepts that contradictions can be true. The lecture is part of a series on paraconsistency and dialetheism, and it sets the stage for further discussion on the nature of time and change.
