Wiktionary, the free dictionary.

Altruism is selfless concern for the welfare of others. It is a traditional virtue in many cultures, and central to many religious traditions. In English, this idea was often described as the Golden rule of ethics. Some newer philosophies such as egoism have criticized the concept, with philosophers arguing that there is no moral obligation to help others. Some philosophies such as objectivism go one step further and argue that altruism is immoral as it is based on self-sacrifice. Altruism is the opposite of selfishness.

Altruism can be distinguished from a feeling of loyalty and duty. Altruism focuses on a motivation to help others or a want to do good without reward, while duty focuses on a moral obligation towards a specific individual (for example, God, a king), a specific organization (for example, a government), or an abstract concept (for example, patriotism etc). Some individuals may feel both altruism and duty, while others may not. Pure altruism is giving without regard to reward or the benefits of recognition.

The concept has a long history in philosophical and ethical thought, and has more recently become a topic for psychologists (especially evolutionary psychology researchers), sociologists, evolutionary biologists, and ethologists. While ideas about altruism from one field can have an impact on the other fields, the different methods and focuses of these fields lead to different perspectives on altruism. Researches on altruism were sparked in particular after the murder of Kitty Genovese in 1964,[1] who was stabbed during half an hour, with passive witnesses withholding themselves from helping her.

Etymology

The word "altruism" (derived from French autre "other", in its turn derived from Latin alter "other") was coined by Auguste Comte, the French founder of positivism, in order to describe the ethical doctrine he supported. He believed that individuals had a moral obligation to serve the interest of others or the "greater good" of humanity. Comte says, in his Catechisme Positiviste, that "[the] social point of view cannot tolerate the notion of rights, for such notion rests on individualism. We are born under a load of obligations of every kind, to our predecessors, to our successors, to our contemporaries. After our birth these obligations increase or accumulate, for it is some time before we can return any service.... This ["to live for others"], the definitive formula of human morality, gives a direct sanction exclusively to our instincts of benevolence, the common source of happiness and duty. [Man must serve] Humanity, who we are entirely." As the name of the ethical doctrine is "altruism," doing what the ethical doctrine prescribes has also come to be referred to by the term "altruism" — serving others through placing their interests above one's own.

Altruism in social sciences

Main article: Altruism (ethics)

If one performs an act beneficial to others with a view to gaining some personal benefit, then it isn't an altruistically motivated act. There are several different perspectives on how "benefit" (or "interest") should be defined. A material gain (for example, money, a physical reward, etc.) is clearly a form of benefit, while others identify and include both material and immaterial gains (affection, respect, happiness, satisfaction etc.) as being philosophically identical benefits.

According to psychological egoism, while people can exhibit altruistic behavior, they cannot have altruistic motivations. Psychological egoists would say that while they might very well spend their lives benefitting others with no material benefit (or a material net loss) to themselves, their most basic motive for doing so is always to further their own interests. For example, it would be alleged that the foundational motive behind a person acting this way is to advance their own psychological well-being ("good feelings").

The problem (known in philosophy as the "problem of love") arises from an analysis of the human will and is often debated among Thomistic philosophers. The problem centers on Thomas Aquinas's understanding that human expressions of love are always based partly on love of self and similitude of being: “Even when a man loves in another what he loves not in himself, there is a certain likeness of proportion: because as the latter is to that which is loved in him, so is the former to that which he loves in himself.”[2]

The French philosopher Pierre Rousselot (1878-1915) located the philosophical problem in terms of a pure "ecstatic" or totally selfless love versus an egotistic, more self-interested love, beginning his examination from Aristotle's text (Nicomachean Ethics, Book 9): "The friendly feelings that we bear for another have arisen from the friendly feelings that we bear for ourselves".[3]

Relations between altruist acts and self-interest were a common problem among French 17th century moralists, examined in particular by La Rochefoucauld, as well as Jansenists such as Pascal and Nicole. These authors claimed that all acts of generosity were in fact acts of vanity, a stance later supported by Mandeville. La Rochefoucauld could thus write, in his first Maxim:

"What we call virtues are often just a collection of casual actions and selfish interests which chance or our own industry manages to arrange [in a certain way]. It is not always from valor that men are valiant, or from chastity that women are chaste."

This classical theory, which gave rise to rational egoism, was harshly opposed by Adam Smith in his Theory Of Moral Sentiments:

"It is the great fallacy of Dr Mandeville's book to represent every passion as wholly vicious, which is so in any degree and in any direction. It is thus that he treats every thing as vanity which has any reference either to what are, or to what ought to be, the sentiments of others; and it is by means of this sophistry that he establishes his favourite conclusion, that private vices are public benefits.[4]"

Critics of this theory conflating altruism with vanity and self-interest often reject it on the grounds that it's non-falsifiable; in other words, it is impossible to prove or disprove because immaterial gains such as a "good feelings" cannot be measured or proven to exist in all people performing altruistic acts. Psychological egoism has also been accused of using circular logic: "If a person willingly performs an act, that means he derives personal enjoyment from it; therefore, people only perform acts that give them personal enjoyment". This particular statement is circular because its conclusion is identical to its hypothesis (it assumes that people only perform acts that give them personal enjoyment, and concludes that people only perform acts that give them personal enjoyment).

In common parlance, altruism usually means helping another person without expecting material reward from that or other persons, although it may well entail the "internal" benefit of a "good feeling," sense of satisfaction, self-esteem, fulfillment of duty (whether imposed by a religion or ideology or simply one's conscience), or the like. In this way one need not speculate on the motives of the altruist in question.

Humans are not exclusively altruistic towards family members, previous co-operators or potential future allies, but can be altruistic towards people they don't know and will never meet. For example, some humans donate to international charities and volunteer their time to help society's less fortunate. It can however be argued that an individual would contribute to a charity to gain respect or stature within his/her own community.

Altruism and game theory

It may strain plausibility to claim that these altruistic deeds are done in the hope of a return favor. Influenced by the consequentialist perspective of utilitarianism, the game theory analysis of this 'just in case' strategy, where the principle would be 'always help everyone in case you need to pull in a favor in return', is a decidedly non-optimal strategy, where the net expenditure of effort is far greater than the net profit when it occasionally pays off.

According to some[attribution needed], it is difficult to believe that these behaviors are solely explained as indirect selfish rationality, be it conscious or unconscious. Mathematical formulations of kin selection, along the lines of the prisoner's dilemma, are helpful as far as they go; but what a game-theoretic explanation glosses over is the fact that altruistic behavior can be attributed to that apparently mysterious phenomenon, the conscience. One recent suggestion, proposed by the philosopher Daniel Dennett, was initially developed when considering the problem of so-called 'free riders' in the tragedy of the commons, a larger-scale version of the prisoner's dilemma.

In game theory terms, a free rider is an agent who draws benefits from a cooperative society without contributing. In a one-to-one situation, free riding can easily be discouraged by a tit-for-tat strategy. But in a larger-scale society, where contributions and benefits are pooled and shared, they can be incredibly difficult to shake off.

Imagine an elementary society of cooperative organisms. Cooperative agents interact with each other, each contributing resources and each drawing on the common good. Now imagine a rogue free rider, an agent who draws a favor ("you scratch my back") and later refuses to return it. The problem is that free riding is always going to be beneficial to individuals at cost to society. How can well-behaved cooperative agents avoid being cheated? Over many generations, one obvious solution is for cooperators to evolve the ability to spot potential free riders in advance and refuse to enter into reciprocal arrangements with them. Then, the canonical free rider response is to evolve a more convincing disguise, fooling cooperators into cooperating after all. This can lead to an evolutionary arms races, with ever-more-sophisticated disguises and ever-more-sophisticated detectors.

In this evolutionary arms race, how best might one convince comrades that one really is a genuine cooperator, not a free rider in disguise? One answer is by actually making oneself a genuine cooperator, by erecting psychological barriers to breaking promises, and by advertising this fact to everyone else. In other words, a good solution is for organisms to evolve things that everyone knows will force them to be cooperators - and to make it obvious that they've evolved these things. According to this theory, evolution will thus produce organisms who are sincerely moral and who wear their hearts on their sleeves; in short, evolution will give rise to the phenomenon of conscience.

This theory, combined with ideas of kin selection and the one-to-one sharing of benefits, may explain how a blind process can produce a genuinely non-cynical form of altruism that gives rise to the human conscience.

Critics of such technical game theory analysis point out that it appears to forget that human beings are rational and emotional. To presume an analysis of human behavior without including human rationale or emotion is necessarily unrealistically narrow, and treats human beings as if they are mere machines, sometimes called Homo economicus. Another objection is that often people donate anonymously, so that it is impossible to determine if they really did the altruistic act (compare with Kant's affirmation that since motive determines the moral nature of an act, and that none can know for sure which motive was behind an act, therefore it is impossible to know if one single moral act ever existed).

Beginning with an understanding that rational human beings benefit from living in a benign universe, logically it follows that particular human beings may gain substantial emotional satisfaction from acts which they perceive to make the world a better place.

Altruism in moral and politics

Altruists may be divided in two broad groups[citation needed]: Those who believe altruism is a matter of personal choice (and therefore selfishness can and should be tolerated - ethical egoism even supports egoism as a moral stance, denying altruism any value), and those who believe that altruism is a moral ideal which should be embraced, if possible, by all human beings.

A prominent example of the former branch of altruist political thought is Lysander Spooner, who, in Natural Law, writes:

"Man, no doubt, owes many other moral duties to his fellow men; such as to feed the hungry, clothe the naked, shelter the homeless, care for the sick, protect the defenceless, assist the weak, and enlighten the ignorant. But these are simply moral duties, of which each man must be his own judge, in each particular case, as to whether, and how, and how far, he can, or will, perform them."

Since Aristotle's classical distinction of regimes made in Politics, III, altruism is often held to be the kind of ethic that should guide the actions of politicians and other people in positions of power. Such people are usually expected to set their own interests aside and serve the populace. When they do not, they may be criticized as defaulting on what is believed to be an ethical obligation to place the interests of others above their own.

Ayn Rand, the founder of the objectivist philosophy argued that altruism operates on the principle of self-sacrifice and was hence intrinsically immoral. She defined sacrifice as the exchange of something of superior value for something of inferior value. Rand argued that the fundamental moral value to a living entity was life. Without that value there would be no living entities. As the universe follows consistent laws and living beings must take certain actions to survive, she argued, the moral code cannot be arbitrary but must follow a rational framework.[5]


Sacrifice according to Rand was the worst kind of moral transgression as it fundamentally undermines the basic principle of a living entity: the optimization towards something better and not something worse. She argued that if altruism in its self-sacrificial form was truly embraced universally human kind would not remain in existence for long.[5]

Altruism and deep ecology

Norwegian Philosopher Arne Næss, a proponent of deep ecology, has suggested that the narrow concept of egoic self implies that all acts of "doing good" are acts of altruism, whereas, through a larger concept of the self-actualised "ecological self", in which it is the interconnectedness within progressively larger wholes, ultimately incorporating the whole of life (see Gaia hypothesis), means that our self interest ultimately requires the flourishing and well-being of the whole of life itself. This concept, similar in some respects to the land ethic of Aldo Leopold, sets the concept of Altruism within the widest possible boundary of moral concern.[6]

Altruism in ethology and evolutionary biology

In the science of ethology (the study of behavior), and more generally in the study of social evolution, altruism refers to behavior by an individual that increases the fitness of another individual while decreasing the fitness of the actor.[citation needed] Researchers on alleged altruist behaviours among animals have been ideologically opposed to the social darwinist concept of the "survival of the fittest", under the name of "survival of the nicest" — the latter being globally compatible, however, with darwinist' theory of evolution. Insistence on such cooperative behaviours between animals was first exposed by the Russian zoologist and anarchist Peter Kropotkin in his 1902 book, Mutual Aid: A Factor of Evolution.

Recent developments in game theory (look into ultimatum game) have provided some explanations for apparent altruism, as have traditional evolutionary analyses. Among the proposed mechanisms are:
