Utilitarianism is an ethical theory holding that the proper course of action is the one that maximizes the overall "happiness". It is thus a form of consequentialism, meaning that the moral worth of an action is determined only by its resulting outcome, and that one can only weigh the morality of an action after knowing all its consequences. Two influential contributors to this theory are Jeremy Bentham and John Stuart Mill. Utilitarianism was described by Mill as "the greatest happiness principle" and by Bentham as the "pleasure principle".^[1]

Utilitarianism can be characterised as a quantitative and reductionist approach to ethics. It is a type of naturalism.^[2] It can be contrasted with deontological ethics (which do not regard the consequences of an act as a determinant of its moral worth), pragmatic ethics, virtue ethics (which focuses on character) and deontological varieties of libertarianism, as well as with ethical egoism and other varieties of consequentialism.

Early utilitarianism[link]

Although modern utilitarianism is usually thought to start with Jeremy Bentham there were earlier writers who presented theories that were strikingly similar. In An Enquiry Concerning the Principles of Morals David Hume writes:

"In all determinations of morality, this circumstance of public utility is ever principally in view; and wherever disputes arise, either in philosophy or common life, concerning the bounds of duty, the question cannot, by any means, be decided with greater certainty, than by ascertaining, on any side, the true interests of mankind.

Hume had studied under Francis Hutcheson and it was he who first introduced a key utilitarian phrase. In An Inquiry into the Original of Our Ideas of Beauty and Virtue Hutcheson writes,

'In comparing the moral Qualitys of Actions, in order to regulate our Election among various Actions propos’d, or to find which of them has the greatest moral Excellency, we are led by our moral Sense of Virtue to judge thus; that in equal Degrees of Happiness, expected to proceed from the Action, the Virtue is in proportion to the Number of Persons to whom the Happiness shall extend; (and here the Dignity, or moral Importance of Persons, may compensate Numbers) and in equal Numbers, the Virtue is as the Quantity of the Happiness, or natural Good; or that the Virtue is in a compound Ratio of the Quantity of Good, and Number of Enjoyers. In the same manner, the moral Evil, or Vice, is as the Degree of Misery, and Number of Sufferers; so that, that Action is best, which procures the greatest Happiness for the greatest Numbers; and that, worst, which, in like manner, occasions Misery.'

In the first three editions of the book Hutcheson followed this passage with various mathematical algorithms “to compute the Morality of any Actions”. In this he pre-figured the hedonic calculus of Bentham.

It is claimed ^[3] that the first systematic theory of utilitarian ethics was developed by John Gay. In Concerning the Fundamental Principle of Virtue or Morality Gay argues that

“happiness, private happiness, is the proper or ultimate end of all our actions… each particular action may be said to have its proper and peculiar end…(but)…. they still tend or ought to tend to something farther; as is evident from hence, viz. that a man may ask and expect a reason why either of them are pursued: now to ask the reason of any action or pursuit, is only to enquire into the end of it: but to expect a reason, i.e. an end, to be assigned for an ultimate end, is absurd. To ask why I pursue happiness, will admit of no other answer than an explanation of the terms.”

This pursuit of happiness is given a theological basis:

“Now it is evident from the nature of God, viz. his being infinitely happy in himself from all eternity, and from his goodness manifested in his works, that he could have no other design in creating mankind than their happiness; and therefore he wills their happiness; therefore the means of their happiness: therefore that my behaviour, as far as it may be a means of the happiness of mankind, should be such…thus the will of God is the immediate criterion of Virtue, and the happiness of mankind the criterion of the wilt of God; and therefore the happiness of mankind may be said to be the criterion of virtue, but once removed…(and)… I am to do whatever lies in my power towards promoting the happiness of mankind. (865)

Gay’s theological utilitarianism was developed and popularized by William Paley. It has been claimed^[4] that Paley was not a very original thinker and that the philosophical part of his treatise on ethics is “an assemblage of ideas developed by others and is presented to be learned by students rather than debated by colleagues”. Nevertheless, his book The Principles of Moral and Political Philosophy was a required text at Cambridge^[5] and Smith^[6] says that Paley’s writings were “once as well known in American colleges as were the readers and spellers of William McGuffey and Noah Webster in the elementary schools.” Although now largely missing from the philosophical canon, Schneewind writes that ‘utilitarianism first became widely known in England through the work of William Paley’. The now forgotten significance of Paley can be judged from the title of Birks 1874 work Modern Utilitarianism or the Systems of Paley, Bentham and Mill Examined and Compared.

Apart from restating that happiness as an end is grounded in the nature of God, Paley also discusses the place of rules. He writes,

“…actions are to be estimated by their tendency. Whatever is expedient, is right. It is the utility of any moral rule alone, which constitutes the obligation of it.

But to all this there seems a plain objection, viz. that many actions are useful, which no man in his senses will allow to be right. There are occasions, in which the hand of the assassin would be very useful… The true answer is this; that these actions, after all, are not useful, and for that reason, and that alone, are not right.

To see this point perfectly, it must be observed that the bad consequences of actions are twofold, particular and general. The particular bad consequence of an action, is the mischief which that single action directly and immediately occasions. The general bad consequence is, the violation of some necessary or useful general rule…

You cannot permit one action and forbid another, without showing a difference between them. Consequently, the same sort of actions must be generally permitted or generally forbidden. Where, therefore, the general permission of them would be pernicious, it becomes necessary to lay down and support the rule which generally forbids them.” (Book II, chapter 6)

Classical Utilitarianism[link]

Jeremy Bentham[link]

Bentham's book An Introduction to the Principles of Morals and Legislation was printed in 1780 but not published until 1789. It is possible that Bentham was spurred on to publish after he saw the success of Paley’s The Principles of Moral and Political Philosophy.^[7] Bentham's book was not an immediate success ^[8] but his ideas were spread further when Pierre Étienne Louis Dumont translated edited selections from a variety of Bentham's manuscripts into French. Traité de legislation civile et pénale was published in 1802 and then later retranslated back into English by Hildreth as The Theory of Legislation, although by this time significant portions of Dumont’s work had already been retranslated and incorporated into Sir John Bowring's edition of Bentham's works, which was issued in parts between 1838 and 1843.

Bentham's work opens with a statement of the principle of utility,

“Nature has placed mankind under the governance of two sovereign masters, pain and pleasure. It is for them alone to point out what we ought to do… By the principle of utility is meant that principle which approves or disapproves of every action whatsoever according to the tendency it appears to have to augment or diminish the happiness of the party whose interest is in question: or, what is the same thing in other words to promote or to oppose that happiness. I say of every action whatsoever, and therefore not only of every action of a private individual, but of every measure of government.”

In Chapter IV Bentham introduces a method of calculating the value of pleasures and pains, which has come to be known as the hedonic calculus. Bentham says that the value of a pleasure or pain, considered by itself, can be measured according to its intensity, duration, certainty/uncertainty and propinquity/remoteness. In addition, it is necessary to consider “the tendency of any act by which it is produced” and, therefore, to take account of the act’s fecundity, or the chance it has of being followed by sensations of the same kind and its purity, or the chance it has of not being followed by sensations of the opposite kind. Finally, it is necessary to consider the extent, or the number of people affected by the action.

Perhaps aware that Hutcheson eventually removed his algorithms for calculating the greatest happiness because they “appear’d useless, and were disagreeable to some readers” ^[9] Bentham contends that there is nothing novel or unwarranted about his method for “in all this there is nothing but what the practice of mankind, wheresoever they have a clear view of their own interest, is perfectly conformable to.”

Rosen warns^[10] that descriptions of utilitarianism can bear “little resemblance historically to utilitarians like Bentham and J.S.Mill” and can be more “a crude version of act utilitarianism conceived in the twentieth century as a straw man to be attacked and rejected.” It is a mistake to think that Bentham is not concerned with rules. His seminal work is concerned with the principles of legislation and the hedonic calculus is introduced with the words “Pleasures then, and the avoidance of pains, are the ends that the legislator has in view.” In Chapter VII Bentham says, “The business of government is to promote the happiness of the society, by punishing and rewarding… In proportion as an act tends to disturb that happiness, in proportion as the tendency of it is pernicious, will be the demand it creates for punishment.”

The question then arises as to when, if at all, it might legitimate to break the law. This is considered in The Theory of Legislation where Bentham distinguishes between evils of the first and second orders. Those of the first order are the more immediate consequences; those of the second are when the consequences spread through the community causing ‘alarm’ and ‘danger’.

“It is true there are cases in which, if we confine ourselves to the effects of the first order, the good will have an incontestable preponderance over the evil. Were the offence considered only under this point of view, it would not be easy to assign any good reasons to justify the rigour of the laws. Every thing depends upon the evil of the second order; it is this which gives to such actions the character of crime, and which makes punishment necessary. Let us take, for example, the physical desire of satisfying hunger. Let a beggar, pressed by hunger, steal from a rich man's house a loaf, which perhaps saves him from starving, can it be possible to compare the good which the thief acquires for himself, with the evil which the rich man suffers? … It is not on account of the evil of the first order that it is necessary to erect these actions into offences, but on account of the evil of the second order.”

John Stuart Mill[link]

Mill was brought up as a Benthamite with the explicit intention that would carry on the cause of utilitarianism.^[11] Mill's book Utilitarianism first appeared as a series of three articles published in Fraser's Magazine in 1861 and was reprinted as a single book in 1863.

Mill rejects a purely quantitative measurement of utility and says,

“It is quite compatible with the principle of utility to recognise the fact, that some kinds of pleasure are more desirable and more valuable than others. It would be absurd that while, in estimating all other things, quality is considered as well as quantity, the estimation of pleasures should be supposed to depend on quantity alone.”

Mill notes that, contrary to what its critics might say, there is “no known Epicurean theory of life which does not assign to the pleasures of the intellect… a much higher value as pleasures than to those of mere sensation.” However, he accepts that this is usually because the intellectual pleasures are thought to have circumstantial advantages, i.e. “greater permanency, safety, uncostliness, &c.” Instead, Mill will argue that some pleasures are intrinsically better than others.

The accusation that hedonism is “doctrine worthy only of swine” has a long history. In Nicomachean Ethics (Book 1 Chapter 5) Aristotle says that identifying the good with pleasure is to prefer a life suitable for beasts. The theological utilitarians had the option of grounding their pursuit of happiness in the will of God; the hedonistic utilitarians needed a different defense. Mill’s approach is to argue that the pleasures of the intellect are intrinsically superior to physical pleasures.

"Few human creatures would consent to be changed into any of the lower animals, for a promise of the fullest allowance of a beast's pleasures; no intelligent human being would consent to be a fool, no instructed person would be an ignoramus, no person of feeling and conscience would be selfish and base, even though they should be persuaded that the fool, the dunce, or the rascal is better satisfied with his lot than they are with theirs… A being of higher faculties requires more to make him happy, is capable probably of more acute suffering, and is certainly accessible to it at more points, than one of an inferior type; but in spite of these liabilities, he can never really wish to sink into what he feels to be a lower grade of existence… It is better to be a human being dissatisfied than a pig satisfied; better to be Socrates dissatisfied than a fool satisfied. And if the fool, or the pig, are of a different opinion, it is because they only know their own side of the question… "^[12]

Mill argues that if people who are “competently acquainted” with two pleasures show a decided preference for one even if it be accompanied by more discontent and “would not resign it for any quantity of the other” then it is legitimate to regard that pleasure as being superior in quality. Mill recognises that these ‘competent judges’ will not always agree, in which case the judgment of the majority is to be accepted as final. Mill also acknowledges that “many who are capable of the higher pleasures, occasionally, under the influence of temptation, postpone them to the lower. But this is quite compatible with a full appreciation of the intrinsic superiority of the higher.” Mill says that this appeal to those who have experienced the relevant pleasures is no different to what must happen when assessing the quantity of pleasure for there is no other way of measuring “the acutest of two pains, or the intensest of two pleasurable sensations.”

Types of utilitarianism[link]

This unreferenced section requires citations to ensure verifiability.

Act utilitarianism states that, when faced with a choice, we must first consider the likely consequences of potential actions and, from that, choose to do what we believe generates the most pleasure for particular situations. The rule utilitarian, on the other hand, begins by looking at potential rules of action, and determine whether there is a rule that should be followed and what would happen if the rule were to be constantly followed. If adherence to the rule produces more happiness than otherwise, it is a rule that morally must be followed at all times. The distinction between act and rule utilitarianism is therefore based on a difference about the proper object of consequential calculation — specific to a case or generalized to rules.

Rule utilitarianism has been criticized for advocating general rules that, in some specific circumstances, clearly decrease happiness if followed. Never to kill another human being may seem to be a good rule, but it could make self-defense against malevolent aggressors very difficult. Rule utilitarians add, however, that there are general exception rules that allow the breaking of other rules if such rule-breaking increases happiness, one example being self-defense. Critics argue that this reduces rule utilitarianism to act utilitarianism and makes rules meaningless. Rule utilitarians retort that rules in the legal system (i.e., laws) that regulate such situations are not meaningless. Self-defense is legally justified, while murder is not.

However, within rule utilitarianism there is a distinction between the strictness and absolutism of this particular branch of utilitarianism. Strong Rule Utilitarianism is an absolutist theory, which frames strict rules that apply for all people and all time and may never be broken.Weak Rule utilitarianism posits that, although rules should be framed on previous examples that benefit society, it is possible, under specific circumstances, to do what produces the greatest happiness and break that rule. An example would be the Gestapo asking where your Jewish neighbours were; a strong rule utilitarian might say the "Do not lie" rule must never be broken, whereas a weak rule utilitarian would argue that to lie would produce the most happiness.

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

Collapse of rule utilitarianism into act utilitarianism[link]

It has been argued that rule utilitarianism collapses into act utilitarianism, because for any given rule, in the case where breaking the rule produces more utility, the rule can be refined by the addition of a sub-rule that handles cases like the exception.^[13] This process holds for all cases of exceptions, and so the ‘rules’ have as many ‘sub-rules’ as there are exceptional cases, which, in the end, makes an agent seek out whatever outcome produces the maximum utility.^[14]

Two-level[link]

Two-level utilitarianism states that one should normally use 'intuitive' moral thinking, in the form of rule utilitarianism, because it usually maximizes happiness. However there are some times when we must ascend to a higher 'critical' level of reflection in order to decide what to do, and must think and act as a utilitarian would. Richard Hare supported this theory with his concept of the Archangel, which holds that if we were all 'archangels' we could be act utilitarians all the time as we would be able to perfectly predict consequences. However we are closer to 'proles' in that we are frequently biased and unable to foresee all possible consequence of our actions, and thus we require moral guidelines. When these principles clash we must attempt to think like an archangel to choose the right course of action.

Motive[link]

Motive utilitarianism, first developed by Robert Adams (Journal of Philosophy, 1976), can be viewed either as a hybrid between act and rule or as a unique approach all on its own terms. The motive approach attempts to deal realistically with how human beings actually function psychologically. We are indeed passionate, emotional creatures, we do much better with positive goals than with negative prohibitions, we long to be taken seriously, and so on and so forth. Motive utilitarianism proposes that our initial moral task be to inculcate within ourselves and others the skills, inclinations, and mental focuses that are likely to be most useful (or in less perfectionist terms, merely highly useful) across the spectrum of real-world situations we are likely to face, rather than the hypothetical situations seemingly so common in philosophical publications. Indeed, motive utilitarianism can even be seen as a response to this unofficial rule^{[clarification needed]} against textured real-world examples. For example, similar to the 80-20 rule in business and entrepreneurship, we might be able to most improve the future prospects of all sentient creatures if we do a large number of activities in open partnerships with others, rather than a few perfect things done sneakily.Two examples of motive utilitarianism in practice might be a gay person coming out of the closet and a politician publicly breaking with a war. In both cases, there is likely to be an initial surge of power and confidence, as well as a transitional period in which one is likely to be losing old friends before making new friends, and unpredictably so on both counts. Another example might be a doctor who is a skilled diagnostician. Such a physician is likely to spend most of their serious study time or continuing education time on current research, direct skills for running a successful practice, etc., and only occasionally return to first principles—that is, only occasionally do something as an interesting study in biochemistry, and then as much as a hobby as anything else.^{[citation needed]}

Negative[link]

Most utilitarian theories deal with producing the greatest amount of good for the greatest number of people. Negative utilitarianism requires us to promote the least amount of evil or harm, or to prevent the greatest amount of suffering for the greatest number. Proponents like Karl Popper, Christoph Fehige ^[15] and Clark Wolf ^[16] argue that this is a more effective ethical formula, since, they contend, the greatest harms are more consequential than the greatest goods. Karl Popper also referred to an epistemological argument: “It adds to clarity in the fields of ethics, if we formulate our demands negatively, i.e., if we demand the elimination of suffering rather than the promotion of happiness.”.^[17] In the practical implementation of this idea the following versions can be distinguished:

1. R.N.Smart, an advocate of the utilitarian principle, was 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 suffering. NU would seem to call for the destruction of the world even if only to avoid the pain of a pinprick.^[18]

2. Negative preference utilitarianism avoids the problem of moral killing, but still demands a justification for the creation of new lives.^[19] Optimistic negative utilitarians believe that, in time, the worst cases of suffering are defeated and a world of minor suffering can be realized. The principal agents of this direction can be found in the environment of abolitionism (bioethics).^[20]

3. Finally there are theoreticians who see negative utilitarianism as a branch within classical utilitarianism, which assigns a higher weight to the avoidance of suffering than to the promotion of happiness.^[21] The moral weight of suffering can be increased by using a "compassionate" utilitarian metric, so that the result is the same as in prioritarianism.^[22]

[edit] Average vs total

Total utilitarianism advocates measuring the utility of a population based on the total utility of its members. According to Derek Parfit, this type of utilitarianism falls victim to the Repugnant Conclusion, whereby large numbers of people with very low but non-negative utility values can be seen as a better goal than a population of a less extreme size living in comfort. In other words, according to the theory, it is a moral good to breed more people on the world for as long as total happiness rises.^[23]

Average utilitarianism, on the other hand, advocates measuring the utility of a population based on the average utility of that population. It avoids Parfit's repugnant conclusion, respectively the mere addition paradox, but causes other problems. For example, bringing a moderately happy person into a very happy world would be seen as an immoral act; aside from this, the theory implies that it would be a moral good to eliminate all people whose happiness is below average, as this would raise the average happiness.^[24]

Other species[link]

Peter Singer

Peter Singer, along with many animal rights activists, has argued that the well-being of all sentient beings ought to be seriously considered. Singer suggests that rights are conferred according to the level of a creature's self-awareness, regardless of their species. He adds that humans tend to be speciesist (discriminatory against non-humans) in ethical matters. Bentham made a similar argument, writing "the question is not, Can they reason? nor, Can they talk? but, Can they suffer?".^[1]

In his 1990 edition of Animal Liberation, Peter Singer said that he no longer ate oysters and mussels, because although the creatures might not suffer, they might, it’s not really known, and it’s easy enough to avoid eating them in any case^[25] (and this aspect of seeking better alternatives is a prominent part of utilitarianism).

All the same, this view still might be contrasted with deep ecology, which holds that an intrinsic value is attached to all forms of life and nature, whether sentient or not. According to utilitarianism, most forms of life (i.e. non-animals) are unable to experience anything akin to either enjoyment or discomfort, and are therefore denied moral status.^{[citation needed]} Thus, the moral value of one-celled organisms, as well as some multi-cellular organisms, and natural entities like a river, is only in the benefit they provide to sentient beings. Similarly, utilitarianism places no direct intrinsic value on biodiversity, although as far as indirect, contingent value, it most probably does.

Combinations with other ethical schools[link]

To overcome perceived shortcomings of both systems, several attempts have been made to reconcile utilitarianism with Kant's categorical imperative. James Cornman proposes that, in any given situation, we should treat as "means" as few people as possible and as "ends" as many as are consistent with those "means". He refers to this as the "utilitarian Kantian principle". In How to Make Good Decisions and Be Right All the Time: Solving the Riddle of Right and Wrong (2008), Iain King develops a quasi-utilitarian system compatible with consequence, virtue and act based accounts of ethics.^[26]

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

Biological explanation[link]

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:

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.

Justification[link]

John Stuart Mill provides the most commonly used justification for Utilitarianism. He tries to prove the theory definitionally. He argues that "good" is a value judgement. Value judgements are judgements of desirability. Therefore, when a person says that an action is good, that person states that the action is desirable. From this argument, Mill concludes that all moral (i.e. good) actions must promote desirable consequences. This creates an important distinction between seeking happiness as an ends and seeking desirable consequences which in turn cause happiness. In Utilitarianism, John Stuart Mill writes:

The principle of utility does not mean that any given pleasure, as music, for instance, or any given exemption from pain, as for example health, are to be looked upon as means to a collective something termed happiness, and to be desired on that account. They are desired and desirable in and for themselves; besides being means, they are a part of the end. Virtue, according to the utilitarian doctrine, is not naturally and originally part of the end, but it is capable of becoming so; and in those who love it disinterestedly it has become so, and is desired and cherished, not as a means to happiness, but as a part of their happiness. ^[27]

Criticisms[link]

This article's Criticism or Controversy section may compromise the article's neutral point of view of the subject. Please integrate the section's contents into the article as a whole, or rewrite the material. (August 2009)

Lack of convincing proof[link]

One possible criticism of utilitarianism is that it is not proven to be the correct ethical system by either science or logic. Utilitarians claim that this is common to all ethical schools and even formal logic itself. As anyone attempts to justify a claim (e.g. "we ought to maximize the pleasure of conscious creatures") they must appeal to other facts, which themselves must be justified. Eventually one is forced to justify their system of justification. This is called the regress argument and philosophers have attempted to address it in various ways.

In light of the regress argument, some philosophers make a sort of appeal to common sense or practicality. In that vein, during discussions on philosophy of law, H.L.A. Hart mentions that foundational philosophical definitions are not "true" but rather agreed upon;^[28] for example, discussions cannot reasonably begin unless all parties simply accept basic laws of thought. This may be the case for discussions of morality; a philosopher does not discover and share the true nature of morality, but rather invites other philosophers to define words like "good" (in the case of ethics) a certain way. Philosophy, and moral systems, thus involve a sort of scientific process of operationalization.

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 the most.

Mill's own argument for utilitarianism holds that pleasure is the only thing desired and that, therefore, pleasure is the only thing desirable. Critics counter argue that Mill is neglecting things that are "morally desirable" even though humans may not desire them. Indeed, there may be things that humans cannot desire that are "morally desirable". This criticism, however, reads desirable as able to be desired rather than worth being desired. That is, the utilitarian may contend that only pleasure can be meaningfully said to be desirable.

The is-ought problem may remain yet another barrier to proving any ethical system, although ethical naturalists reject this problem.

Aggregating utility[link]

John Rawls gives a critique of utilitarianism in A Theory of Justice that rejects the idea that the happiness of two distinct persons could be meaningfully counted together. He argues that this entails treating a group of many as if it were a single sentient entity, ignoring the separation of consciousness.^[29] Animal rights advocate Richard Ryder calls this the ‘boundary of the individual’, through which neither pain nor pleasure may pass.^[30] Thus the aggregation of utility becomes futile as both pain and happiness are intrinsic to and inseparable from the consciousness in which they are felt, rendering impossible the task of adding up the various pleasures of multiple individuals. However, it should be noted that the apparent separation of individual consciousnesses, which is both a strong human intuition and an implicit premise in this critique, is itself a subject of debate in the philosophy of mind.

One classical liberal defense against Rawl’s criticism can be made by asking the simple question: who must figure out the exact sum of all individuals' happiness? No subjectively calculated measure of aggregate happiness is necessary nor useful for society. To doubt the ability (for someone) to add up individuals’ feelings, is to suggest that there necessarily is someone (a person, a bunch of persons, or computers) whose job is to figure out that sum, before a related social decision can be made. If there were such "someone", the situation would be analogous to a centrally-planned economy, where a few socialist bureaucrats constantly struggle to figure out what, how much, by whom, and for whom goods are to be produced.^[31]

Predicting consequences[link]

Daniel Dennett uses the case of the Three Mile Island accident as an example of the difficulty in calculating happiness.^[32] 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, 33 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.^{[citation needed]} That something cannot be determined at the moment is common in science and frequently resolved with later advancements.

Anthony Kenny argues against utilitarianism using the "standard argument" against free will. The argument supposes that determinism is either true or false: if it is true, we have no choice over our actions; but if it is false, the consequences of our actions are unpredictable, not least because they depend upon the actions of others whom we cannot predict. This may render incoherent claims about moral responsibility.^[33] On the other hand, hard determinist utilitarians see no problem for moral responsibility. They suggest that certain notions of "retributive justice" for its own sake may now be incoherent, but there remain other, more reasonable purposes for punishment.

Importance of intentions[link]

Utilitarianism has been accused of looking only at the results of actions, and disregarding the desires or intentions that motivate them. Intentions seem somehow important: it seems undesirable to call an action intended to cause harm but that inadvertently causes good "overall good".

Many utilitarians argue that utilitarianism, although it is consequentalist, is not so simply restricted. While the results of a hatefully motivated action may indeed be "good", this does not suggest that the motivation of "hate" should be normatively advocated in society. Put simply, when using utilitarianism to decide which practices or even values to promote in a society, one might consider whether "hate" normally leads to "good" or "bad" outcomes. This may allow utilitarianism to become a much more complex and rich moral theory, and may align far more closely with our moral intuitions. In this sense, intentions are important to utilitarians, in as much as they tend to lead to certain actions, which themselves lead to certain outcomes. One classic philosopher to take this view is Henry Sidgwick, in his main work The Methods of Ethics (1874).

Human rights[link]

This section needs additional citations for verification. Please help improve this article by adding citations to reliable sources. Unsourced material may be challenged and removed. (September 2011)

Utilitarians argue that justification of slavery, torture or mass murder would require unrealistically large benefits to outweigh the direct and extreme suffering to victims. Utilitarianism would also require the indirect impact of social acceptance of inhumane policies to be taken into consideration, and general anxiety and fear could increase for all if human rights are commonly ignored.

Act and rule utilitarians 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 that they reject them altogether: first, most act utilitarians, as explained above, would agree that acts such as enslavement and genocide always cause great unhappiness and very little happiness; second, human rights could be considered rules of thumb so that, although torture might be acceptable under some circumstances, as a rule it is immoral; and, finally, act utilitarians often support human rights in a legal sense because utilitarians support laws that cause more good than harm.

[edit] Individual interests vs a greater sum of lesser interests

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

Karl Marx's criticisms[link]

Karl Marx, in Das Kapital, writes:

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 inquiry had to investigate what sorts of things are good for people—that is, what our nature, 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 one-dimensional 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.

Wittgensteinian critique[link]

Contemporary philosophers such as Matthew Ostrow have critiqued utilitarianism from a distinctly Wittgensteinian perspective. According to these philosophers, utilitarians have expanded the very meaning of pleasure to the point of linguistic incoherence.^{[citation needed]} The utilitarian groundlessly places pleasure as his or her first principle, and in doing so subordinates the value of asceticism, self-sacrifice or any other "secondary" desire. The utilitarian denies that this is a problem, either by claiming that "secondary" desires amount to different paths to achieving the first desire of pleasure or that any practice of asceticism that does not create pleasure either for the ascetic or for others is valueless.

Such an argument may seem tautological ("What is it that people want? Pleasure. But what is pleasure? What people want."), as the utilitarian therefore has no ultimate justification for why we ought to primarily value pleasure. If this is the case, utilitarianism would be reduced to a form of ethical intuitionism, rather than its own fully grounded theory. Utilitarianism will then depend on intuitionist grounds, needing to be supported or rejected on this deeper level. Because of this, such critics argue utilitarianism is in-itself an empty concept or a pseudo-problem.

John Paul II's personalist criticism[link]

Pope John Paul II, following his personalist philosophy, considered that a danger of utilitarianism is that it tends to make persons, just as much as things, the object of use. "Utilitarianism is a civilization of production and of use, a civilization of things and not of persons, a civilization in which persons are used in the same way as things are used".^[35]

John Stuart Mill, FRSE (20 May 1806 – 8 May 1873) was a British philosopher, political economist and civil servant. He was an influential contributor to social theory, political theory, and political economy. He has been called "the most influential English-speaking philosopher of the nineteenth century".^[5] Mill's conception of liberty justified the freedom of the individual in opposition to unlimited state control.^[6] He was a proponent of utilitarianism, an ethical theory developed by Jeremy Bentham. Hoping to remedy the problems found in an inductive approach to science, such as confirmation bias, he clearly set forth the premises of falsification as the key component in the scientific method.^[7] Mill was also a Member of Parliament and an important figure in liberal political philosophy.

Biography[link]

John Stuart Mill was born on Rodney Street in the Pentonville area of London, the eldest son of the Scottish philosopher, historian and economist James Mill, and Harriet Burrow. John Stuart was educated by his father, with the advice and assistance of Jeremy Bentham and Francis Place. He was given an extremely rigorous upbringing, and was deliberately shielded from association with children his own age other than his siblings. His father, a follower of Bentham and an adherent of associationism, had as his explicit aim to create a genius intellect that would carry on the cause of utilitarianism and its implementation after he and Bentham had died.^[8]

Mill was a notably precocious child. He describes his education in his autobiography. At the age of three he was taught Greek.^[9] By the age of eight he had read Aesop's Fables, Xenophon's Anabasis,^[9] and the whole of Herodotus,^[9] and was acquainted with Lucian, Diogenes Laërtius, Isocrates and six dialogues of Plato.^[9] He had also read a great deal of history in English and had been taught arithmetic.

At the age of eight he began learning Latin, Euclid, and algebra, and was appointed schoolmaster to the younger children of the family. His main reading was still history, but he went through all the commonly taught Latin and Greek authors and by the age of ten could read Plato and Demosthenes with ease. His father also thought that it was important for Mill to study and compose poetry. One of Mill's earliest poetry compositions was a continuation of the Iliad. In his spare time, he also enjoyed reading about natural sciences and popular novels, such as Don Quixote and Robinson Crusoe.

His father's work, The History of British India was published in 1818; immediately thereafter, about the age of twelve, Mill began a thorough study of the scholastic logic, at the same time reading Aristotle's logical treatises in the original language. In the following year he was introduced to political economy and studied Adam Smith and David Ricardo with his father, ultimately completing their classical economic view of factors of production. Mill's comptes rendus of his daily economy lessons helped his father in writing Elements of Political Economy in 1821, a textbook to promote the ideas of Ricardian economics; however, the book lacked popular support.^[10] Ricardo, who was a close friend of his father, used to invite the young Mill to his house for a walk in order to talk about political economy.

At age fourteen, Mill stayed a year in France with the family of Sir Samuel Bentham, brother of Jeremy Bentham. The mountain scenery he saw led to a lifelong taste for mountain landscapes. The lively and friendly way of life of the French also left a deep impression on him. In Montpellier, he attended the winter courses on chemistry, zoology, logic of the Faculté des Sciences, as well as taking a course of the higher mathematics. While coming and going from France, he stayed in Paris for a few days in the house of the renowned economist Jean-Baptiste Say, a friend of Mill's father. There he met many leaders of the Liberal party, as well as other notable Parisians, including Henri Saint-Simon.
