#19: Modelling Moral Debate using Reason-based Abstract Argumentation Theory
Alex Jackson · Michael Luck · Elizabeth Black
Keywords: [ argumentation ] [ debate ] [ Reasoning ] [ moral dilemmas ]
Using an extended form of abstract argumentation, we model moral debate formally and define a game for computational ethics that involves human moral judgements. In general, the absence of universal criteria for assessing moral reasoning makes defining a formal representation of moral debate challenging. In this work, we unify John Broome’s concept of a ‘reason’ with argumentation theory, and demonstrate our formalism with a debate on trolley problem moral dilemmas.
