Rule egoism is the doctrine under which an individual evaluates the optimal set of rules according to whether conformity to those rules bring the most benefit to himself.^[1] An action, therefore, is right if it promotes his welfare at least as well as any alternative rule available to him.^[2] It is associated with foundational egoism, which maintains that normative factors must be grounded in consideration of the agent's well-being - something that rule egoism does but in a way that avoids factoral egoism.^[3]
