Equal consideration of interests is the name of a moral principle that states that one should both include all affected interests when calculating the rightness of an action, and weigh those interests equally. The term "equal consideration of interests" first appeared in Peter Singer's Practical Ethics. The idea is that individual rights are unimportant philosophically; what is instead much more relevant is the consideration of an individual's interests. The principle thus opposes those theories that either exclude some interests from the moral calculus or weigh certain interests differently from others. Jeremy Bentham's dictum, "each to count for one, and none for more than one" can be considered a formulation of the principle of equal consideration of interests, and a basis for the broader philosophy of utilitarianism. The principle also underlies Peter Singer's views, who is a moral utilitarian that has explicitly adopted it as the foundation of his ethical theory.
