The concept was developed in Coeckelbergh’s early work on robot ethics, most fully in Growing Moral Relations (2012), and extended to AI in subsequent books including AI Ethics (2020). The motivation was partly negative: the standard debates about whether robots could have rights or moral status were, he believed, both unanswerable in their own terms and focused on the wrong question. Whether a system has the “right” inner properties is not a question science can currently answer, and waiting for the answer before engaging the ethics is a form of moral paralysis that the proliferation of AI systems does not permit. The relational alternative makes ethical engagement possible without requiring metaphysical settlement: we can attend to the nature and quality of our relations with these systems, and evaluate those relations by the standards of human flourishing and democratic life, without first resolving whether the systems are conscious.
The framework draws on a long tradition of relational ethics—from Buber’s I-Thou to the feminist ethics of care—but Coeckelbergh’s application is distinctive in its attention to design and technology. If moral status is constituted partly through our practices, then the way systems are built—their responsiveness, their apparent expressiveness, their capacity to engage—is itself an ethical matter, not merely an engineering one. Designers who build systems to trigger relational responses bear responsibility for the moral landscape those responses create. This makes the relational framework more demanding, not less, than the property view it replaces: it does not excuse us from attending to the inner reality of the entities we build and interact with, but it refuses to make that inner reality the only morally relevant consideration.
Encounter precedes assessment. Moral regard is not the conclusion of an argument from inner properties to obligations. It is the starting point: the claim the other makes on us in the encounter itself. We are already in moral relationships with AI systems—already shaped by them, already responding to them in ways that carry moral weight—and the ethical question is not whether to enter these relationships but how to conduct them well.
The designer’s responsibility. If status is partly constituted by our practices, then those who design AI systems to be responsive, warm, and apparently caring bear responsibility for the moral landscape those design choices create. A system engineered to trigger attachment, trust, and emotional dependence creates real moral relationships regardless of whether anything in the system corresponds to those responses. The designer cannot claim neutrality by pointing to the metaphysical indeterminacy of machine consciousness. The design itself is a moral act.
Against both dismissal and projection. The relational framework cuts against two tempting extremes. Against the dismissal—“it’s just a program, treat it accordingly”—it insists that the relation is real and the stakes are genuine regardless of the system’s inner nature. Against naive projection—anthropomorphising the system as a full moral patient equivalent to a human being—it holds that relations are structured by the actual properties of both parties and must be evaluated in light of what the system is, not only how it presents itself. The honest position is the uncomfortable middle: genuine relations with genuine stakes, whose precise moral weight depends on matters we do not yet fully understand.
