Strategic Interaction in Kantian Utopia: The Prisoner's Dilemma

ABSTRACT What does the Kantian realm of ends look like? To partially answer that question, game theory will be used to analyse how Kantians would handle situations of strategic interaction. Starting from a thorough understanding of Kant's categorical imperative, three purportedly Kantian game theoretical models will be analysed and argued to be inconsistent with the categorical imperative. As these existing models are unfit for analysing strategic interaction in the realm of ends, a genuinely Kantian model will be constructed by adding the concepts of ‘moral field’, ‘moral range’ and ‘Kantian utility function’ to the standard game‐theoretical model. Throughout the paper, the prisoner's dilemma will be used both as a case study and as a ground for argumentation.
