Philosophers Examine Identity Through Temporal Change

This article examines puzzles about identity over time, focusing on the cup/truncated-cup example and debates over numerical versus qualitative identity among philosophers such as David Lewis. It analyzes tensions with Leibniz’s Law, distinguishes synchronic and diachronic identity, and surveys responses including constitution, temporal parts, and Geach’s relative-identity proposal, underscoring consequences for metaphysical accounts of persistence.
