Extending the Tracks: Temporal Agency and the Structural Flaw in the Trolley Problem

Abstract

For nearly sixty years, the trolley problem has dominated moral philosophy as the canonical thought experiment for ethical decision-making. Since Philippa Foot’s original formulation in 1967, thousands of papers have debated which track to choose. This paper argues they have all been answering the wrong question. The trolley problem’s most consequential feature is not the binary choice between tracks but the artificial elimination of temporal agency; the removal of time as a resource available to the moral actor. Real moral emergencies almost never present as instantaneous binary forks. They unfold across time, with lead indicators, intervention windows, and opportunities for harm mitigation that the trolley problem systematically excludes by design. This paper proposes a structural resolution in the form of the Temporal Extension Principle (TEP), a two-part moral action consisting of (1) immediate harm prevention for the proximate threat and (2) active intervention against the deferred threat using the time created by the first action. This reframing transforms the trolley problem from a dilemma (choose who suffers) into a project (prevent suffering across time). The paper demonstrates the principle’s real-world applicability through the Harm Blindness Framework’s four-checkpoint
