Intro to Philosophy
Utilitarianism is a philosophical view or theory about how we should evaluate a wide range of things that involve choices that people face. Among the things that can be evaluated are actions, laws, policies, character traits, and moral codes. Utilitarianism is a form of consequentialism because it rests on the idea that it is the consequences or results of actions, laws, policies, etc. that determine whether they are good or bad, right or wrong. In general, whatever is being evaluated, we ought to choose the one that will produce the best overall results. In the language of utilitarians, we should choose the option that “maximizes utility,” i.e. that action or policy that produces the largest amount of good.
Utilitarianism appears to be a simple theory because it consists of only one evaluative principle: Do what produces the best consequences. In fact, however, the theory is complex because we cannot understand that single principle unless we know (at least) three things: a) what things are good and bad; b) whose good (i.e. which individuals or groups) we should aim to maximize; and c) whether actions, policies, etc. are made right or wrong by their actual consequences (the results that our actions actually produce) or by their foreseeable consequences (the results that we predict will occur based on the evidence that we have).
Jeremy Bentham answered this question by adopting the view called hedonism. According to hedonism, the only thing that is good in itself is pleasure (or happiness). Hedonists do not deny that many different kinds of things can be good, including food, friends, freedom, and many other things, but hedonists see these as “instrumental” goods that are valuable only because they play a causal role in producing pleasure or happiness. Pleasure and happiness, however, are “intrinsic” goods, meaning that they are good in themselves and not because they produce some further valuable thing. Likewise, on the negative side, a lack of food, friends, or freedom is instrumentally bad because it produces pain, suffering, and unhappiness; but pain, suffering and unhappiness are intrinsically bad, i.e. bad in themselves and not because they produce some further bad thing.
Many thinkers have rejected hedonism because pleasure and pain are sensations that we feel, claiming that many important goods are not types of feelings. Being healthy or honest or having knowledge, for example, are thought by some people to be intrinsic goods that are not types of feelings. (People who think there are many such goods are called pluralists or”objective list” theorists.) Other thinkers see desires or preferences as the basis of value; whatever a person desires is valuable to that person. If desires conflict, then the things most strongly preferred are identified as good.
In this article, the term “well-being” will generally be used to identify what utilitarians see as good or valuable in itself. All utilitarians agree that things are valuable because they tend to produce well-being or diminish ill-being, but this idea is understood differently by hedonists, objective list theorists, and preference/desire theorists. This debate will not be further discussed in this article.
Both act utilitarians and rule utilitarians agree that our overall aim in evaluating actions should be to create the best results possible, but they differ about how to do that.
Act utilitarians believe that whenever we are deciding what to do, we should perform the action that will create the greatest net utility. In their view, the principle of utility—do whatever will produce the best overall results—should be applied on a case by case basis. The right action in any situation is the one that yields more utility (i.e. creates more well-being) than other available actions.
Rule utilitarians adopt a two part view that stresses the importance of moral rules. According to rule utilitarians, a) a specific action is morally justified if it conforms to a justified moral rule; and b) a moral rule is justified if its inclusion into our moral code would create more utility than other possible rules (or no rule at all). According to this perspective, we should judge the morality of individual actions by reference to general moral rules, and we should judge particular moral rules by seeing whether their acceptance into our moral code would produce more well-being than other possible rules.
The key difference between act and rule utilitarianism is that act utilitarians apply the utilitarian principle directly to the evaluation of individual actions while rule utilitarians apply the utilitarian principle directly to the evaluation of rules and then evaluate individual actions by seeing if they obey or disobey those rules whose acceptance will produce the most utility.
The contrast between act and rule utilitarianism, though previously noted by some philosophers, was not sharply drawn until the late 1950s when Richard Brandt introduced this terminology. (Other terms that have been used to make this contrast are “direct” and “extreme” for act utilitarianism, and “indirect” and “restricted” for rule utilitarianism.) Because the contrast had not been sharply drawn, earlier utilitarians like Bentham and Mill sometimes apply the principle of utility to actions and sometimes apply it to the choice of rules for evaluating actions. This has led to scholarly debates about whether the classical utilitarians supported act utilitarians or rule utilitarians or some combination of these views. One indication that Mill accepted rule utilitarianism is his claim that direct appeal to the principle of utility is made only when “secondary principles” (i.e. rules) conflict with one another. In such cases, the “maximize utility” principle is used to resolve the conflict and determine the right action to take. Mill, Utilitarianism, Chapter 2
Act utilitarianism is often seen as the most natural interpretation of the utilitarian ideal. If our aim is always to produce the best results, it seems plausible to think that in each case of deciding what is the right thing to do, we should consider the available options (i.e. what actions could be performed), predict their outcomes, and approve of the action that will produce the most good.
If every action that we carry out yields more utility than any other action available to us, then the total utility of all our actions will be the highest possible level of utility that we could bring about. In other words, we can maximize the overall utility that is within our power to bring about by maximizing the utility of each individual action that we perform. If we sometimes choose actions that produce less utility than is possible, the total utility of our actions will be less than the amount of goodness that we could have produced. For that reason, act utilitarians argue, we should apply the utilitarian principle to individual acts and not to classes of similar actions.
The most common argument against act utilitarianism is that it gives the wrong answers to moral questions. Critics say that it permits various actions that everyone knows are morally wrong. The following cases are among the commonly cited examples:If a judge can prevent riots that will cause many deaths only by convicting an innocent person of a crime and imposing a severe punishment on that person, act utilitarianism implies that the judge should convict and punish the innocent person. (See Rawls and also Punishment.)If a doctor can save five people from death by killing one healthy person and using that person’s organs for life-saving transplants, then act utilitarianism implies that the doctor should kill the one person to save five.If a person makes a promise but breaking the promise will allow that person to perform an action that creates just slightly more well-being than keeping the promise will, then act utilitarianism implies that the promise should be brokenThe general form of each of these arguments is the same. In each case, act utilitarianism implies that a certain act is morally permissible or required. Yet, each of the judgments that flow from act utilitarianism conflicts with widespread, deeply held moral beliefs. Because act utilitarianism approves of actions that most people see as obviously morally wrong, we can know that it is a false moral theory.Unlike act utilitarians, who try to maximize overall utility by applying the utilitarian principle to individual acts, rule utilitarians believe that we can maximize utility only by setting up a moral code that contains rules. The correct moral rules are those whose inclusion in our moral code will produce better results (more well-being) than other possible rules. Once we determine what these rules are, we can then judge individual actions by seeing if they conform to these rules. The principle of utility, then, is used to evaluate rules and is not applied directly to individual actions. Once the rules are determined, compliance with these rules provides the standard for evaluating individual actions.
Act utilitarians criticize rule utilitarians for irrationally supporting rule-based actions in cases where more good could be done by violating the rule than obeying it. They see this as a form of “rule worship,” an irrational deference to rules that has no utilitarian justification (J. J. C. Smart).
Act utilitarians say that they recognize that rules can have value. For example, rules can provide a basis for acting when there is no time to deliberate. In addition, rules can define a default position, a justification for doing (or refraining from) a type of action as long as there is no reason for not doing it. But when people know that more good can be done by violating the rule then the default position should be over-ridden.
The debate between act utilitarianism and rule utilitarianism highlights many important issues about how we should make moral judgments. Act utilitarianism stresses the specific context and the many individual features of the situations that pose moral problems, and it presents a single method for dealing with these individual cases. Rule utilitarianism stresses the recurrent features of human life and the ways in which similar needs and problems arise over and over again. From this perspective, we need rules that deal with types or classes of actions: killing, stealing, lying, cheating, taking care of our friends or family, punishing people for crimes, aiding people in need, etc. Both of these perspectives, however, agree that the main determinant of what is right or wrong is the relationship between what we do or what form our moral code takes and what is the impact of our moral perspective on the level of people’s well-being.
