This article discusses utilitarian ethical theory. For a discussion of John Stuart Mill's essay Utilitarianism (1861), see Utilitarianism (book).

Utilitarianism (from the Latin utilis, useful) is a theory of ethics that prescribes the quantitative maximization of good consequences for a population. It is a form of consequentialism. This good to be maximized is usually happiness, pleasure, or preference satisfaction. Though some utilitarian theories might seek to maximize other consequences, these consequences generally have something to do with the welfare of people (or of people and nonhuman animals). For this reason, utilitarianism is often associated with the term welfarist consequentialism.

History of utilitarianism

Utilitarianism was first proposed by the Chinese philosopher Mozi, who lived some time between the years of 479-381 B.C. during the Warring States Period. He was the founder of the school of Mohism in ancient China and advocated a utilitarian ethical system some 1,800 years before it was promoted as a viable principle in Europe.

European Utilitarianism was originally proposed by Jeremy Bentham. From the principle of utility, Bentham found pain and pleasure to be the only absolutes in the world: "nature has put man under the governance of two sovereign masters: pleasure and pain." From this he derived the rule of utility: that the good is whatever brings the greatest happiness to the greatest number of people. Later, after realizing that the formulation recognized two different and potentially conflicting principles, he dropped the second part and talked simply about "the greatest happiness principle."

In his famous (and short) book, Utilitarianism, John Stuart Mill argued that cultural, intellectual, and spiritual pleasures are of greater value than mere physical pleasure, because the former would be valued more highly by competent judges than the latter. A competent judge, according to Mill, is anyone who has experienced both the lower pleasures and the higher. Like Bentham's formulation, Mill's utilitarianism is hedonistic, because it deals with pleasure/happiness.

The classic utilitarianism of Bentham and Mill influenced many other philosophers and the development of the broader concept of consequentialism. As a result, the correct definitions of utilitarianism and consequentialism and the exact difference between these two principles are not always entirely clear, even among philosophers.

Other past advocates of utilitarianism include William Godwin, James Mill, and Henry Sidgwick; modern-day advocates include R.M. Hare and Peter Singer.

Utilitarianism has been used as an argument for many different political views. In his essay On Liberty and other works, John Stuart Mill argued that utilitarianism requires that political arrangements satisfy the "liberty principle", according to which each person must be guaranteed the greatest possible liberty that would not interfere with the liberty of others, so that each person may maximize his or her happiness. Ludwig von Mises advocated libertarianism using utilitarian arguments. Likewise, some Marxist philosophers have also used these principles as arguments for political socialism.

Types of utilitarianism

Negative utilitarianism

Most utilitarian theories deal with producing the greatest amount of good for the greatest number. Negative utilitarianism requires us to promote the least amount of evil or harm, or to prevent the greatest amount of harm for the greatest number. Proponents argue that this is a more effective ethical formula, since, they contend, there are many more ways to do harm than to do good, and the greatest harms are more consequential than the greatest goods.

However, some advocates of the utilitarian principle were quick to suggest that the ultimate aim of negative utilitarianism would be to engender the quickest and least painful method of killing the entirety of humanity, as this ultimately would effectively minimize pain. Negative utilitarianism would seem to call for the destruction of the world even if only to avoid the pain of a pinprick. Yet the "pinprick argument" ^* or the notion that negative utilitarianism calls for world destruction is not accepted by all philosophers.

Act utilitarianism vs. rule utilitarianism

Act utilitarianism states that, when faced with a choice, we must first consider the likely consequences of potential actions, and from that, chose to do what we believe will generate the most happiness. A rule utilitarian, on the other hand, begins by looking at potential rules of action. To determine whether a rule should be followed, he looks at what would happen if it was constantly followed. If adherence to the rule produces more happiness than otherwise, it is a rule that morally must be followed at all times. In this way, rule utilitarianism is a more of a proportionalistic ethical theory.

To illustrate, consider the following scenario: A surgeon has five terminal patients: one needs a liver, one needs a pancreas, one needs a heart, and two need kidneys. A sixth, non-terminal patient just came in to have his appendix removed. Should the surgeon kill the sixth man and pass his organs around to the others?

An act utilitarian would consider the probable consequences of sacrificing the sixth patient that one time, while a rule utilitarian would look at the consequences of performing such a sacrifice every time such a situation arises. One potential rule would be: "whenever a surgeon could kill one relatively healthy person in order to transplant his organs to more than one other person who needs them, he ought to do so." If instituted in society, this rule would obviously lead to bad consequences. Relatively healthy people would stop going to the hospital, many risky transplant operations would be performed, etc. Therefore, a rule utilitarian would say we should implement the opposite rule: "don't harvest healthy people's organs to give them to sick people." For a rule utilitarian, therefore, it would be immoral for the surgeon to kill the sixth man. Of course, it is possible that the act utilitarian would decide not to sacrifice the sixth man, but most would agree that rule utiltarianism would provide stronger reasons not to.

Rule utilitarianism has been criticized for advocating general rules that will in some specific circumstances clearly decrease happiness if followed. To never kill a human might seem to be a good rule, but this could make defense against aggressors very difficult. Rule utilitarians would then add that there are general exception rules that allows the breaking of other rules if this increases happiness, one example being self-defense. Critics would then argue that this reduces rule utilitarianism to act utilitarianism, and the rules become meaningless. Rule utilitarians respond that the rules in the legal system (i.e., laws) which regulate such situations are not meaningless. For instance, self-defense is legally justified while murder is not.

Rule utilitarianism should not be confused with rules of thumb. Many act utilitarians agree that it makes sense to formulate certain rules of thumb to follow if they find themselves in a situation in which the consequences are difficult, costly, or time-consuming to calculate exactly. If the consequences can be calculated relatively clearly and without much doubt, then the rules of thumb can be ignored.

Preference utilitarianism

Preference utilitarianism is a particular type of utilitarianism which defines the good to be maximized as the fulfillment of persons' preferences. Like any utilitarian theory, preference utilitarianism claims that the right thing to do is that which produces the best consequences; when defined in terms of preference satisfaction, the best consequences can include things other than pure hedonism, like reputation or rationality.

Preference utilitarianism is favored by the modern utilitarian philosopher Peter Singer, who was influenced by R.M. Hare.

Other species

Peter Singer, along with animal rights activists, has argued that the well-being of all sentient beings (conscious beings who feel pain, including animals) deserve equal consideration with that given to human beings. Bentham made a similar argument. Even those utilitarians arguing otherwise note that suffering in animals often causes humans to suffer, thus making it often immoral to harm an animal even if the animal itself is not given a moral status.

Combinations with other ethical schools

In order to overcome perceived shortcomings of both systems, several attempts have been made to combine utilitarianism with Kant's categorical imperative. For instance, James Cornman proposes that in any given situation we should treat as "means" as few people as possible, and treat as "ends" as many people as are thus then consistent with those "means". He refers to this as the "Utilitarian Kantian Principle".

Other consequentialists may consider happiness an important consequence, but in addition argue that consequences such as justice or equality should also be valued, regardless if they increase happiness or not.

Biological explanation for utilitarianism

It has been suggested that sociobiology, the study of the evolution of human society, provides support for the utilitarian point of view. For example, in The Expanding Circle: Ethics and Sociobiology, the utilitarian philosopher Peter Singer argues that fundamentally utilitarian ethical reasoning has existed from the time primitive foraging bands had to cooperate, compromise, and make group decisions to survive. He elaborates: "In a dispute between members of a cohesive group of reasoning beings, the demand for a reason is a demand for a justification that can be accepted by the group as a whole." Thus, consideration of others' interests has long been a necessary part of the human experience. Singer believes that reason now compels the equal consideration of all people's interests:

If I have seen that from an ethical point of view I am just one person among the many in my society, and my interests are no more important, from the point of view of the whole, than the similar interests of others within my society, I am ready to see that, from a still larger point of view, my society is just one among other societies, and the interests of members of my society are no more important, from that larger perspective, than the similar interests of members of other societies… Taking the impartial element in ethical reasoning to its logical conclusion means, first, accepting that we ought to have equal concern for all human beings.

This conclusion -- that everybody's interests should be considered equally when making decisions -- is a core tenet of utilitarianism.

Singer elaborates that viewing oneself as equal to others in one's society and at the same time viewing one's society as fundamentally superior to other societies may cause an uncomfortable cognitive dissonance. This is the sense in which he means that reason may push people to accept a broader utilitarian stance. Critics (e.g. Binmore 2005) point out that this cognitive dissonance is apparently not very strong, since people often knowingly ignore the interests of faraway societies quite similar to their own. They also note that the "ought" of the quoted paragraph applies only to someone who has already accepted the premise that all societies are equally important. Singer has responded that his argument in Expanding the Circle wasn't intended to provide a complete philosophical justification for a utilitarian categorical imperative, but merely to provide a plausible explanation for how some people come to accept utilitarianism.

Criticism of utilitarianism

Utilitarianism and "common sense" morality

Utilitarianism has been criticized for leading to a number of conclusions contrary to "common sense" morality. For example, it might be argued that it is "common sense" that one should never sacrifice some humans for the happiness of other humans (an ethical position famously explored in Le Guin's modern fable "The Ones Who Walk Away From Omelas"). Utilitarians, however, argue that "common sense" has been used to justify many positions on both sides of controversial issues and varies greatly from individual to individual, making it an unsuitable basis for a "common" morality. Regarding the example, it is equally "common sense" that one must sacrifice some soldiers and civilians in a defensive war.

Comparing happiness

Another difficulty with utilitarianism is that of comparing happiness among different people. Many of the early utilitarians hoped that happiness could somehow be measured quantitatively and compared between people through felicific calculus, although no one has ever managed to construct a detailed one in practice. It has been argued that the happiness of different people is incommensurable, and thus felicific calculus is impossible, not only in practice, but even in principle. Defenders of utilitarianism reply that this problem is faced by anyone who has to choose between two alternative states of affairs where both impose burdens to the people involved. If happiness were incommensurable, the death of a hundred people would be no worse than the death of one. Triage is an example of a real world situation where utilitarianism seems to be applied successfully.

That the pleasure of a sadist should have the same importance as the pleasure of an altruist has also been criticized. Supporters note that in practice almost no decisions will be made to cater to the sadist. While creating pleasure for an altruist simultaneously helps other people, creating pleasure for a sadist simultaneously hurts other people. Furthermore, many utilitarians feel that sadist pleasure is superficial and temporary, and thus it is detrimental to the sadist in the long run. In practice, therefore, the pleasure of a sadist almost never has a weight of any significance in a utilitarian calculation.

Predicting consequences

Daniel Dennett uses the example of Three Mile Island as another example of the difficulty in calculating happiness. Was the near-meltdown that occurred at this nuclear power plant a good or a bad thing (according to utilitarianism)? He points out that its long-term effects on nuclear policy would be considered beneficial by many and might outweigh the negative consequences. His conclusion is that it is still too early (20 years after the event) for utilitarianism to weigh all the evidence and reach a definite conclusion. Utilitarians note that utilitarianism seems to be the unspoken principle used by both advocates and critics of nuclear power. That something cannot be determined at the moment is common in science and is frequently resolved with further advancements.

Utilitarians, however, are not required to have perfect knowledge; indeed, certain knowledge of consequences is impossible because consequences are in the unexperienced future. Utilitarians simply try their best to maximize happiness (or another form of utility), and to do this, makes their best estimates of the consequences. If the consequences of a decision are particularly unclear, it might make sense to follow an ethical rule which has promoted the most utility in the past. Utilitarians will also note that people trying to further their own interests run into situations in which the consequences of their decisions are very unclear. This does not mean that they are unable to make a decision.

The importance of intentions

Utilitarianism has been criticized for only looking at the results of actions, not at the desires or intentions which motivate them, which many people also consider important. An action intended to cause harm but that inadvertently causes good results would be judged equal to the result from an action done with good intentions. However, many utilitarians would argue that utilitarianism applies not only to results, but also to desires and dispositions, praise and blame, rules, institutions, and punishment. For instance, bad intentions may cause harm (to the actor and to others) even if they do not result in bad acts. Once this is recognized, supporters argue that utilitarianism becomes a much more complex, and rich, moral theory, and may align much more closely with our moral intuitions.

Furthermore, many utilitarians view morality as a personal guide rather as a means to judge the actions of other people or actions which have already been performed. In other words, morality is something to be looked at when deciding what to do. In this sense, intentions are the only thing that matter, because the consequences cannot be known with certainty until the decision has already been made.

One philosopher to take this view was Henry Sidgwick in his main work The Methods of Ethics, 1874.

Human rights

Some critics reject utilitarianism, both rule and act, on the basis that it seems to be incompatible with human rights. For example, if slavery or torture is beneficial for the population as a whole, it could theoretically be justified by utilitarianism. Utilitarian theory thus seems to overlook the rights of minority groups. It might also ignore the rights of the majority. A man might achieve such pure ecstasy from killing 100 people so that his positive utility outweighs the negative utility of the 100 people he murdered.

Utilitarians may argue that justification of either slavery, torture or mass murder would require unrealistically large benefits to outweigh the direct and extreme suffering to the victims (although some may support one of these practices as being justifiable by the consequences achieved). Utilitarianism would also require the indirect impact of social acceptance of inhumane policies to be taken into consideration; for example, general anxiety and fear might increase for all if human rights are commonly ignored.

Act and rule utilitarianisms differ in how they treat human rights themselves. Under rule utilitarianism, a human right can easily be considered a moral rule. Act utilitarians, on the other hand, do not accept human rights as moral principles in and of themselves, but that does not mean they are rejected altogether. First, most act utilitarians, as explained above, would agree that acts such as enslavement and genocide always cause great unhappiness and little happiness. Second, human rights could be considered rules of thumb; although torture might be acceptable under some circumstances, as a rule it is immoral. Finally, act utilitarians often support human rights in a legal sense, because utilitarians support laws that cause more good than harm.

Sacrifice of an important individual interest for a greater sum of lesser interests

Since utilitarians judge all actions by their ability to maximize good consequences, any harm to one individual can always be justified by a greater gain to other individuals. This is true even if the loss for the one individual is large and the gain for the others is marginal, as long as enough individuals receive the small benefit. Thus, utilitarians deny that individuals have inviolable moral rights. As explained above, utilitarians may support legal rights or rights as rules of thumb, but they are not considered inherent to morality. This seems problematic to many critics of utilitarianism, one of whom notes that according to utilitarianism there is "nothing intrinsically wrong with sacrificing an important individual interest to a greater sum of lesser interests. That assumption is retained in the foundations of the theory, and it remains a source of moral concern."Waldron, Jeremy. ''Rights'. A Companion to Contemporary Political Philosophy, editors Goodin, Robert E. and Pettit, Philip. Blackwell Publishing, 1995, p.581.

Althought the above criticism is not, two other common criticisms of utilitarianism are based on misconceptions. The principle of "the greatest good for the greatest number", introduced by Bentham, is often mistaken as meaning that if something hurts one person and helps many, it is always moral. This is not the case, however; as noted above, Bentham dropped the misleading "greatest number" part of the principle, replacing the original formulation with the more direct "greatest happiness principle." Thus, the morality of an action is not determined by the number of people made happier, but rather the quantity of happiness produced. A great loss to one individual might be outweighed by small gains for many, but it might not. Even if 1 person is hurt and 100 people are helped, the harm to the one might be so great as to outweigh the small gains for the rest of the people.

Second, many mistakenly believe utilitarianism means individuals interests are sacrificed for the sake of the "society" or the nation. According to utilitarianism, however, one individual's interests can only be sacrificed for the sake of the interests of other individuals. As Bentham put it, "It is vain to talk of the interest of the community, without understanding what is the interest of the individual." ^* While it may benefit individuals to have a healthy society or a functional state, neither of these are ends in themselves.

Right and wrong dichotomy

A further criticism is in regard to Utilitarianism's judgement of right and wrong. Utilitarianism holds that in any given situation the 'right' act is that which produced the greatest good, while all other acts are wrong. Therefore even charitable actions could be considered wrong under this theory. For example, if someone donated $1,000 to a charity that provided starving children with food when that person could have donated the money to a charity that does the same thing but is more efficient, and in doing so created even more good, that action would be judged as wrong by Utilitarianism.

In response to criticism of this nature the contemporary philosopher and utilitarian William Shaw claimed that, although Utilitarianism would clearly dictate the above conclusion, a good utilitarian would still praise the wrongdoer for their charitable donation even though it is wrong. This is because punishing such a person would likely push them to no longer make any charitable contributions, so praising the wrongdoer would better serve the greater good than punishing them.

Furthermore, the decision to donate to charity was still morally good, even if the decision to ignore efficiency was immoral.

Proof

Another criticism of utilitarianism is that it is not proved by science or logic to be the correct ethical system. However, supporters claim that this is common to all ethical schools (and indeed the system of logic itself) and will remain so until the problem of the regress argument or at least the is-ought problem is satisfactorily solved. Indeed, utilitarians are some of the first to recognise this problem. It might instead be argued that almost all political arguments about a future society use an unspoken utilitarian principle, all sides claiming that their proposed solution is the one that increases human happiness most. Some degree of utilitarianism might very well be genetically hard-coded into humans.

Why be moral?

Critics have also asked why one should follow utilitarianism instead of egoism. A legal system might punish behavior which hurts others, but this incentive is not active in a situation where one can personally gain by breaking it and others cannot punish this. However, one egoist may propose means to maximize self-interest that conflicts with the means proposed by another egoist. As a result, they are behooved to compromise with one another to avoid conflict, out of self-interest. The means proposed may incidentally coincide with those prescribed by utilitarianism, though the foundational ethical imperative would not, of course, be utilitarian.

Another reason for an egoist to become a utilitarian was proposed by Peter Singer in Practical Ethics. He presents the paradox of hedonism, which says that if your only goal in life is personal happiness, you will never be happy; you need something to be happy about. One goal which Singer feels is likely to bring personal happiness is the desire to improve the lives of others. This argument is similar to the one for virtue ethics.

Karl Marx's argument concerning the importance of human nature

Karl Marx, in Capital, writes:

Not even excepting our philosopher, Christian Wolff, in no time and in no country has the most homespun commonplace ever strutted about in so self-satisfied a way. The principle of utility was no discovery of Bentham. He simply reproduced in his dull way what Helvétius and other Frenchmen had said with esprit in the 18th century. To know what is useful for a dog, one must study dog-nature. This nature itself is not to be deduced from the principle of utility. Applying this to man, he that would criticise all human acts, movements, relations, etc., by the principle of utility, must first deal with human nature in general, and then with human nature as modified in each historical epoch. Bentham makes short work of it. With the driest naiveté he takes the modern shopkeeper, especially the English shopkeeper, as the normal man. Whatever is useful to this queer normal man, and to his world, is absolutely useful. This yard-measure, then, he applies to past, present, and future. The Christian religion, e.g., is "useful," "because it forbids in the name of religion the same faults that the penal code condemns in the name of the law." Artistic criticism is "harmful," because it disturbs worthy people in their enjoyment of Martin Tupper, etc. With such rubbish has the brave fellow, with his motto, "nulla dies sine line!," piled up mountains of books. ^*

Marx's accusation is twofold. In the first place, he says that the theory of utility is true by definition and thus does not really add anything meaningful. For Marx, a productive enquiry would have to investigate what sorts of things are good for people; that is, what our nature (which he believes is alienated under capitalism) really is. Second, he says that Bentham fails to take account of the changing character of people, and hence the changing character of what is good for them. This criticism is especially important for Marx, because he believed that all important statements were contingent upon particular historical conditions. Marx argues that human nature is dynamic, so the concept of a single utility for all humans is simplistic and not useful. When he decries Bentham's application of the 'yard measure' of now to 'the past, present and future', he decries the implication that society, and people, have always been, and will always be, as they are now; that is, he criticizes essentialism. As he sees it, this implication is conservatively used to reinforce institutions he regarded as reactionary. Just because in this moment religion has some positive consequences, says Marx, doesn't mean that viewed historically it isn't a regressive institution that should be abolished.

Marx's criticism is more a criticism of Bentham's views (or similar views) of utility, than utilitarianism itself. Utilitarians would not deny that different things make different people happy, and that what promotes happiness changes over time. Neither would utilitarians deny the importance of investigations into what promotes utility.

Marx's criticism applies to all analytical philosophy, all philosophy which does not take explicit account of the movement of history (against dialectics). While he's right that all things change, and that it is necessary to take account of this when making practical judgements, this doesn't mean that it isn't useful to have a theory which gives some means to evaluate those changes themselves.

Also, utilitarianism was originally developed as a (moderate) challenge to the status quo. The demand that everyone count for one, and one only, was anathema to the elitist society of Victorian Britain.

Utilitarian criticism of other schools

One criticism is that many other schools cannot even in theory solve real world complex ethical problems when various inviolable principles collide, like triage or if the atomic bombings of Hiroshima and Nagasaki was the right decision.

A criticism of Kantianism is leveled by R. M. Hare in Could Kant Have Been a Utilitarian?. He argues that a number of different ethical positions could fit with Kant's description of his Categorical Imperative, and although Kant did not agree with this assessment, utilitarianism could be among them.
