Deontological International Ethics

Abstract

Deontological international ethics describes, analyzes, and assesses the principles governing the interactions of actors at and across various levels of society; focuses on the relations between states and other international actors; and is concerned with identifying and specifying the moral duties that each kind of international actor bears toward all others. The core theoretical elements of deontological international ethics include accounts of individual and collective agency, moral reason, the moral nature of action, and respect for the moral law as a necessary feature of ethical action. There are three historical phases of deontological international ethics: divine command and natural law ethics prior to Kant, late-modern thinker Immanuel Kant’s international ethics, and contemporary neo-Kantian approaches to nuclear ethics and transnational economic relations. The divine command ethical theories posit divine authority as the absolute and incontrovertible source of moral obligation. Meanwhile, natural law focuses on the intrinsically moral nature of military action and the centrality of moral agency and intention in the rightful use of force. On the other hand, Kant’s systemic deontological ethical theory posits individuals and states as autonomous and rational moral agents, identifies the categorical imperative as the supreme rational principle or morality and the concept of public right as its political corollary, describes a formal method for actors to determine their moral duty in ideal and non-ideal contexts, and applies this theory to the problems of interstate conflict and commerce.
