Altruism is the principle and moral practice of concern for happiness of other human beings and/or animals, resulting in a quality of life both material and spiritual. It is a traditional virtue in many cultures and a core aspect of various religious traditions and secular worldviews, though the concept of "others" toward whom concern should be directed can vary among cultures and religions. In an extreme case, altruism may become a synonym of selflessness which is the opposite of selfishness.
The word "altruism" was coined by the French philosopher Auguste Comte in French, as altruisme, for an antonym of egoism. He derived it from the Italian altrui, which in turn was derived from Latin alteri, meaning "other people" or "somebody else".
Altruism in biological observations in field populations of the day organisms is an individual performing an action which is at a cost to themselves (e.g., pleasure and quality of life, time, probability of survival or reproduction), but benefits, either directly or indirectly, another third-party individual, without the expectation of reciprocity or compensation for that action. Steinberg suggests a definition for altruism in the clinical setting, that is "intentional and voluntary actions that aim to enhance the welfare of another person in the absence of any quid pro quo external rewards". In one sense, the opposite of altruism is spite; a spiteful action harms another with no self-benefit.
Altruism can be distinguished from feelings of loyalty, in that whilst the latter is predicated upon social relationships, altruism does not consider relationships. Much debate exists as to whether "true" altruism is possible in human psychology. The theory of psychological egoism suggests that no act of sharing, helping or sacrificing can be described as truly altruistic, as the actor may receive an intrinsic reward in the form of personal gratification. The validity of this argument depends on whether intrinsic rewards qualify as "benefits".
The term altruism may also refer to an ethical doctrine that claims that individuals are morally obliged to benefit others. Used in this sense, it is usually contrasted with egoism, which claims individuals are morally obligated to serve themselves first. Effective altruism is the use of evidence and reason to determine the most effective ways to benefit others.

The notion of altruism
The concept has a long history in philosophical and ethical thought. The term was originally coined in the 19th century by the founding sociologist and philosopher of science, Auguste Comte, and has become a major topic for psychologists (especially evolutionary psychology researchers), evolutionary biologists, and ethologists. Whilst ideas about altruism from one field can affect the other fields, the different methods and focuses of these fields always lead to different perspectives on altruism. In simple terms, altruism is caring about the welfare of other people and acting to help them.
Marcel Mauss's book The Gift contains a passage called "Note on alms". This note describes the evolution of the notion of alms (and by extension of altruism) from the notion of sacrifice. In it, he writes:
Alms are the fruits of a moral notion of the gift and of fortune on the one hand, and of a notion of sacrifice, on the other. Generosity is an obligation, because Nemesis avenges the poor and the gods for the superabundance of happiness and wealth of certain people who should rid themselves of it. This is the ancient morality of the gift, which has become a principle of justice. The gods and the spirits accept that the share of wealth and happiness that has been offered to them and had been hitherto destroyed in useless sacrifices should serve the poor and children.
- Compare Altruism (ethics) – perception of altruism as self-sacrifice.
- Compare explanation of alms in various scriptures.
In the science of ethology (the study of animal behaviour), and more generally in the study of social evolution, altruism refers to behaviour by an individual that increases the fitness of another individual while decreasing the fitness of the actor. In evolutionary psychology this may be applied to a wide range of human behaviors such as charity, emergency aid, help to coalition partners, tipping, courtship gifts, production of public goods, and environmentalism.
Theories of apparently altruistic behavior were accelerated by the need to produce theories compatible with evolutionary origins. Two related strands of research on altruism have emerged from traditional evolutionary analyses and from evolutionary game theory a mathematical model and analysis of behavioural strategies.
Some of the proposed mechanisms are:
- Kin selection. That animals and humans are more altruistic towards close kin than to distant kin and non-kin has been confirmed in numerous studies across many different cultures. Even subtle cues indicating kinship may unconsciously increase altruistic behavior. One kinship cue is facial resemblance. One study found that slightly altering photographs so that they more closely resembled the faces of study participants increased the trust the participants expressed regarding depicted persons. Another cue is having the same family name, especially if rare, and this has been found to increase helpful behavior. Another study found more cooperative behavior the greater the number of perceived kin in a group. Using kinship terms in political speeches increased audience agreement with the speaker in one study. This effect was especially strong for firstborns, who are typically close to their families.
- Vested interests. People are likely to suffer if their friends, allies, and similar social ingroups suffer or even disappear. Helping such group members may therefore eventually benefit the altruist. Making ingroup membership more noticeable increases cooperativeness. Extreme self-sacrifice towards the ingroup may be adaptive if a hostile outgroup threatens to kill the entire ingroup.
- Reciprocal altruism. See also Reciprocity (evolution).
- Direct reciprocity. Research shows that it can be beneficial to help others if there is a chance that they can and will reciprocate the help. The effective tit for tat strategy is one game theoretic example. Many people seem to be following a similar strategy by cooperating if and only if others cooperate in return.
- One consequence is that people are more cooperative if it is more likely that individuals will interact again in the future. People tend to be less cooperative if they perceive that the frequency of helpers in the population is lower. They tend to help less if they see non-cooperativeness by others and this effect tend to be stronger than the opposite effect of seeing cooperative behaviors. Simply changing the cooperative framing of a proposal may increase cooperativeness such as calling it a "Community Game" instead of a "Wall Street Game."
- A tendency towards reciprocity implies that people will feel obligated to respond if someone helps them. This has been used by charities that give small gifts to potential donors hoping thereby to induce reciprocity. Another method is to announce publicly that someone has given a large donation. The tendency to reciprocate can even generalize so people become more helpful toward others in general after being helped. On the other hand, people will avoid or even retaliate against those perceived not to be cooperating. People sometimes mistakenly fail to help when they intended to, or their helping may not be noticed, which may cause unintended conflicts. As such, it may be an optimal strategy to be slightly forgiving of and have a slightly generous interpretation of non-cooperation.
- People are more likely to cooperate on a task if they can communicate with one another first. This may be due to better assessments of cooperativeness or due to exchange of promises. They are more cooperative if they can gradually build trust, instead of being asked to give extensive help immediately. Direct reciprocity and cooperation in a group can be increased by changing the focus and incentives from intra-group competition to larger scale competitions such as between groups or against the general population. Thus, giving grades and promotions based only on an individual's performance relative to a small local group, as is common, may reduce cooperative behaviors in the group.
- Indirect reciprocity. The avoidance of poor reciprocators and cheaters causes a person's reputation to become very important. A person with a good reputation for reciprocity have a higher chance of receiving help even from persons they have had no direct interactions with previously.
- Strong reciprocity. A form of reciprocity where some individuals seem to spend more resources on cooperating and punishing than would be most beneficial as predicted by several established theories of altruism. A number of theories have been proposed as explanations as well as criticisms regarding its existence.
- Pseudo-reciprocity. An organism behaves altruistically and the recipient does not reciprocate but has an increased chance of acting in a way that is selfish but also as a byproduct benefits the altruist.
- Direct reciprocity. Research shows that it can be beneficial to help others if there is a chance that they can and will reciprocate the help. The effective tit for tat strategy is one game theoretic example. Many people seem to be following a similar strategy by cooperating if and only if others cooperate in return.
- Costly signaling and the handicap principle. Since altruism takes away resources from the altruist it can be an "honest signal" of resource availability and the abilities needed to gather resources. This may signal to others that the altruist is a valuable potential partner. It may also be a signal of interactive and cooperative intentions since those not interacting further in the future gain nothing from the costly signaling. It is unclear if costly signaling can indicate a long-term cooperative personality but people have increased trust for those who help. Costly signaling is pointless if everyone has the same traits, resources, and cooperative intentions but become a potentially more important signal if the population increasingly varies on these characteristics.
- Hunters widely sharing the meat has been seen as a costly signal of ability and research has found that good hunters have higher reproductive success and more adulterous relations even if they themselves receive no more of the hunted meat than anyone else. Similarly, holding large feasts and giving large donations has been seen as ways of demonstrating one's resources. Heroic risk-taking has also been interpreted as a costly signal of ability.
- Both indirect reciprocity and costly signaling depend on the value of reputation and tend to make similar predictions. One is that people will be more helping when they know that their helping behavior will be communicated to people they will interact with later, is publicly announced, is discussed, or is simply being observed by someone else. This have been documented in many studies. The effect is sensitive to subtle cues such as people being more helpful when there were stylized eyespots instead of a logo on a computer screen. Weak reputational cues such as eyespots may become unimportant if there are stronger cues present and may lose their effect with continued exposure unless reinforced with real reputational effects. Public displays such as public weeping for dead celebrities and participation in demonstrations may be influenced by a desire to be seen as altruistic. People who know that they are publicly monitored sometimes even wastefully donate money they know are not needed by recipient which may be because of reputational concerns.
- Women have been found to find altruistic men to be attractive partners. When looking for a long-term partner, altruism may be a preferred trait as it may indicate that he is also willing to share resources with her and her children. It has been shown that men perform altruistic acts in the early stages of a romantic relationship or simply when in the presence of an attractive woman. While both sexes state that kindness is the most preferable trait in a partner there is some evidence that men place less value on this than women and that women may not be more altruistic in presence of an attractive man. Men may even avoid altruistic women in short-term relationships which may be because they expect less success.
- People may compete for social benefit from a burnished reputation, which may cause competitive altruism. On the other hand, in some experiments a proportion of people do not seem to care about reputation and they do not help more even if this is conspicuous. This may possibly be due to reasons such as psychopathy or that they are so attractive that they need not be seen to be altruistic. The reputational benefits of altruism occur in the future as compared to the immediate costs of altruism in the present. While humans and other organisms generally place less value on future costs/benefits as compared to those in the present, some have shorter time horizons than others and these people tend to be less cooperative.
- Explicit extrinsic rewards and punishments have been found to sometimes actually have the opposite effect on behaviors compared to intrinsic rewards. This may be because such extrinsic, top-down incentives may replace (partially or in whole) intrinsic and reputational incentives, motivating the person to focus on obtaining the extrinsic rewards, which overall may make the behaviors less desirable. Another effect is that people would like altruism to be due to a personality characteristic rather than due to overt reputational concerns and simply pointing out that there are reputational benefits of an action may actually reduce them. This may possibly be used as derogatory tactic against altruists, especially by those who are non-cooperators. A counterargument is that doing good due to reputational concerns is better than doing no good at all.
- Group selection. It has controversially been argued by some evolutionary scientists such as David Sloan Wilson that natural selection can act at the level of non-kin groups to produce adaptations that benefit a non-kin group even if these adaptions are detrimental at the individual level. Thus, while altruistic persons may under some circumstances be outcompeted by less altruistic persons at the individual level, according to group selection theory the opposite may occur at the group level where groups consisting of the more altruistic persons may outcompete groups consisting of the less altruistic persons. Such altruism may only extend to ingroup members while there may instead prejudice and antagonism against outgroup members (See also in-group favoritism). Group selection theory has been criticized by many other evolutionary scientists.
Such explanations do not imply that humans are always consciously calculating how to increase their inclusive fitness when they are doing altruistic acts. Instead, evolution has shaped psychological mechanisms, such as emotions, that promote altruistic behaviors.
Every single instance of altruistic behavior need not always increase inclusive fitness; altruistic behaviors would have been selected for if such behaviors on average increased inclusive fitness in the ancestral environment. This need not imply that on average 50% or more of altruistic acts were beneficial for the altruist in the ancestral environment; if the benefits from helping the right person were very high it would be beneficial to err on the side of caution and usually be altruistic even if in most cases there were no benefits.
The benefits for the altruist may be increased and the costs reduced by being more altruistic towards certain groups. Research has found that people are more altruistic to kin than to no-kin, to friends than to strangers, to those attractive than to those unattractive, to non-competitors than to competitors, and to members ingroups than to members of outgroup.
The study of altruism was the initial impetus behind George R. Price's development of the Price equation, which is a mathematical equation used to study genetic evolution. An interesting example of altruism is found in the cellular slime moulds, such as Dictyostelium mucoroides. These protists live as individual amoebae until starved, at which point they aggregate and form a multicellular fruiting body in which some cells sacrifice themselves to promote the survival of other cells in the fruiting body.
Selective investment theory proposes that close social bonds, and associated emotional, cognitive, and neurohormonal mechanisms, evolved in order to facilitate long-term, high-cost altruism between those closely depending on one another for survival and reproductive success.
Such cooperative behaviors have sometimes been seen as arguments for left-wing politics such by the Russian zoologist and anarchist Peter Kropotkin in his 1902 book Mutual Aid: A Factor of Evolution and Peter Singer in his book A Darwinian Left.
Jorge Moll and Jordan Grafman, neuroscientists at the National Institutes of Health and LABS-D'Or Hospital Network (J.M.) provided the first evidence for the neural bases of altruistic giving in normal healthy volunteers, using functional magnetic resonance imaging. In their research, published in the Proceedings of the National Academy of Sciences USA in October 2006, they showed that both pure monetary rewards and charitable donations activated the mesolimbic reward pathway, a primitive part of the brain that usually responds to food and sex. However, when volunteers generously placed the interests of others before their own by making charitable donations, another brain circuit was selectively activated: the subgenual cortex/septal region. These structures are intimately related to social attachment and bonding in other species. Altruism, the experiment suggested, was not a superior moral faculty that suppresses basic selfish urges but rather was basic to the brain, hard-wired and pleasurable. One brain region, the subgenual anterior cingulate cortex/basal forebrain, contributes to learning altruistic behavior, especially in those with trait empathy. The same study has shown a connection between giving to charity and the promotion of social bonding.
In fact, in an experiment published in March 2007 at the University of Southern California neuroscientist Antonio R. Damasio and his colleagues showed that subjects with damage to the ventromedial prefrontal cortex lack the ability to empathically feel their way to moral answers, and that when confronted with moral dilemmas, these brain-damaged patients coldly came up with "end-justifies-the-means" answers, leading Damasio to conclude that the point was not that they reached immoral conclusions, but that when they were confronted by a difficult issue — in this case as whether to shoot down a passenger plane hijacked by terrorists before it hits a major city — these patients appear to reach decisions without the anguish that afflicts those with normally functioning brains. According to Adrian Raine, a clinical neuroscientist also at the University of Southern California, one of this study's implications is that society may have to rethink how it judges immoral people: "Psychopaths often feel no empathy or remorse. Without that awareness, people relying exclusively on reasoning seem to find it harder to sort their way through moral thickets. Does that mean they should be held to different standards of accountability?"
In another study, in the 1990s, Dr. Bill Harbaugh, a University of Oregon economist, concluded people are motivated to give for reasons of personal prestige and in a similar fMRI scanner test in 2007 with his psychologist colleague Dr. Ulrich Mayr, reached the same conclusions of Jorge Moll and Jordan Grafman about giving to charity, although they were able to divide the study group into two groups: "egoists" and "altruists". One of their discoveries was that, though rarely, even some of the considered "egoists" sometimes gave more than expected because that would help others, leading to the conclusion that there are other factors in cause in charity, such as a person's environment and values.
The International Encyclopedia of the Social Sciences defines psychological altruism as "a motivational state with the goal of increasing another’s welfare." Psychological altruism is contrasted with psychological egoism, which refers to the motivation to increase one's own welfare.
There has been some debate on whether or not humans are truly capable of psychological altruism. Some definitions specify a self-sacrificial nature to altruism and a lack of external rewards for altruistic behaviors. However, because altruism ultimately benefits the self in many cases, the selflessness of altruistic acts is brought to question. The social exchange theory postulates that altruism only exists when benefits to the self outweigh costs to the self. Daniel Batson is a psychologist who examined this question and argues against the social exchange theory. He identified four major motives for altruism: altruism to ultimately benefit the self (egoism), to ultimately benefit the other person (altruism), to benefit a group (collectivism), or to uphold a moral principle (principlism). Altruism that ultimately serves selfish gains is thus differentiated from selfless altruism, but the general conclusion has been that empathy-induced altruism can be genuinely selfless. The empathy-altruism hypothesis basically states that psychological altruism does exist and is evoked by the empathic desire to help someone who is suffering. Feelings of empathic concern are contrasted with feelings of personal distress, which compel people to reduce their own unpleasant emotions. People with empathic concern help others in distress even when exposure to the situation could be easily avoided, whereas those lacking in empathic concern avoid helping unless it is difficult or impossible to avoid exposure to another's suffering. Helping behavior is seen in humans at about two years old, when a toddler is capable of understanding subtle emotional cues.
In psychological research on altruism, studies often observe altruism as demonstrated through prosocial behaviors such as helping, comforting, sharing, cooperation, philanthropy, and community service. Research has found that people are most likely to help if they recognize that a person is in need and feel personal responsibility for reducing the person's distress. Research also suggests that the number of bystanders witnessing distress or suffering affects the likelihood of helping (the Bystander effect). Greater numbers of bystanders decrease individual feelings of responsibility. However, a witness with a high level of empathic concern is likely to assume personal responsibility entirely regardless of the number of bystanders.
Many studies have observed the effects of volunteerism (as a form of altruism) on happiness and health and have consistently found a strong connection between volunteerism and current and future health and well-being. In a study of older adults, those who volunteered were higher on life satisfaction and will to live, and lower in depression, anxiety, and somatization. Volunteerism and helping behavior have not only been shown to improve mental health, but physical health and longevity as well, attributable to the activity and social integration it encourages. One study examined the physical health of mothers who volunteered over a 30-year period and found that 52% of those who did not belong to a volunteer organization experienced a major illness while only 36% of those who did volunteer experienced one. A study on adults ages 55+ found that during the four-year study period, people who volunteered for two or more organizations had a 63% lower likelihood of dying. After controlling for prior health status, it was determined that volunteerism accounted for a 44% reduction in mortality. Merely being aware of kindness in oneself and others is also associated with greater well-being. A study that asked participants to count each act of kindness they performed for one week significantly enhanced their subjective happiness. It is important to note that, while research supports the idea that altruistic acts bring about happiness, it has also been found to work in the opposite direction—that happier people are also kinder. The relationship between altruistic behavior and happiness is bidirectional. Studies have found that generosity increases linearly from sad to happy affective states.
Studies have also been careful to note that feeling over-taxed by the needs of others has conversely negative effects on health and happiness. For example, one study on volunteerism found that feeling overwhelmed by others' demands had an even stronger negative effect on mental health than helping had a positive one (although positive effects were still significant). Additionally, while generous acts make people feel good about themselves, it is also important for people to appreciate the kindness they receive from others. Studies suggest that gratitude goes hand-in-hand with kindness and is also very important for our well-being. A study on the relationship happiness to various character strengths showed that "a conscious focus on gratitude led to reductions in negative affect and increases in optimistic appraisals, positive affect, offering emotional support, sleep quality, and well-being.".
"Sociologists have long been concerned with how to build the good society" ("Altruism, Morality, and Social Solidarity". American Sociological Association.). The structure of our societies and how individuals come to exhibit charitable, philanthropic, and other pro-social, altruistic actions for the common good is a largely researched topic within the field. The American Sociology Association (ASA) acknowledges public sociology saying, "The intrinsic scientific, policy, and public relevance of this field of investigation in helping to construct 'good societies' is unquestionable" ("Altruism, Morality, and Social Solidarity" ASA). This type of sociology seeks contributions that aid grassroots and theoretical understandings of what motivates altruism and how it is organized, and promotes an altruistic focus in order to benefit the world and people it studies. How altruism is framed, organized, carried out, and what motivates it at the group level is an area of focus that sociologists seek to investigate in order to contribute back to the groups it studies and "build the good society". The motivation of altruism is also the focus of study; some publications link the occurrence of moral outrage to the punishment of perpetrators and compensation of victims.
Pathological altruism is when altruism is taken to an unhealthy extreme, and either harms the altruistic person, or well-intentioned actions cause more harm than good.
The term "pathological altruism" was popularised by the book Pathological Altruism.
Examples include depression and burnout seen in healthcare professionals, an unhealthy focus on others to the detriment of one's own needs, hoarding of animals, and ineffective philanthropic and social programs that ultimately worsen the situations they are meant to aid.
Most, if not all, of the world's religions promote altruism as a very important moral value. Buddhism, Christianity, Hinduism, Islam, Jainism, Judaism, and Sikhism, etc., place particular emphasis on altruistic morality.
Altruism figures prominently in Buddhism. Love and compassion are components of all forms of Buddhism, and are focused on all beings equally: love is the wish that all beings be happy, and compassion is the wish that all beings be free from suffering. "Many illnesses can be cured by the one medicine of love and compassion. These qualities are the ultimate source of human happiness, and the need for them lies at the very core of our being" (Dalai Lama).
Still, the notion of altruism is modified in such a world-view, since the belief is that such a practice promotes our own happiness: "The more we care for the happiness of others, the greater our own sense of well-being becomes" (Dalai Lama).
In the context of larger ethical discussions on moral action and judgment, Buddhism is characterized by the belief that negative (unhappy) consequences of our actions derive not from punishment or correction based on moral judgment, but from the law of karma, which functions like a natural law of cause and effect. A simple illustration of such cause and effect is the case of experiencing the effects of what one causes: if one causes suffering, then as a natural consequence one would experience suffering; if one causes happiness, then as a natural consequence one would experience happiness.
The fundamental principles of Jainism revolve around the concept of altruism, not only for humans but for all sentient beings. Jainism preaches the view of Ahimsa – to live and let live, thereby not harming sentient beings, i.e. uncompromising reverence for all life. It also considers all living things to be equal. The first Tirthankara, Rishabhdev, introduced the concept of altruism for all living beings, from extending knowledge and experience to others to donation, giving oneself up for others, non-violence and compassion for all living things.
Jainism prescribes a path of non-violence to progress the soul to this ultimate goal. A major characteristic of Jain belief is the emphasis on the consequences of not only physical but also mental behaviors. One's unconquered mind with anger, pride (ego), deceit, greed and uncontrolled sense organs are the powerful enemies of humans. Anger spoils good relations, pride destroys humility, deceit destroys peace and greed destroys everything. Jainism recommends conquering anger by forgiveness, pride by humility, deceit by straightforwardness and greed by contentment.
Jains believe that to attain enlightenment and ultimately liberation, one must practice the following ethical principles (major vows) in thought, speech and action. The degree to which these principles are practiced is different for householders and monks. They are:
- Non-violence (Ahimsa);
- Truthfulness (Satya);
- Non-stealing (Asteya);
- Celibacy (Brahmacharya);
- Non-possession or non-materialism (Aparigraha);
The "great vows" (Mahavrata) are prescribed for monks and "limited vows" (Anuvrata) are prescribed for householders. The house-holders are encouraged to practice the above-mentioned five vows. The monks have to observe them very strictly. With consistent practice, it will be possible to overcome the limitations gradually, accelerating the spiritual progress.
The principle of non-violence seeks to minimize karmas which limit the capabilities of the soul. Jainism views every soul as worthy of respect because it has the potential to become Siddha (God in Jainism). Because all living beings possess a soul, great care and awareness is essential in one's actions. Jainism emphasizes the equality of all life, advocating harmlessness towards all, whether the creatures are great or small. This policy extends even to microscopic organisms. Jainism acknowledges that every person has different capabilities and capacities to practice and therefore accepts different levels of compliance for ascetics and householders.
Altruism is central to the teachings of Jesus found in the Gospel, especially in the Sermon on the Mount and the Sermon on the Plain. From biblical to medieval Christian traditions, tensions between self-affirmation and other-regard were sometimes discussed under the heading of "disinterested love", as in the Pauline phrase "love seeks not its own interests." In his book Indoctrination and Self-deception, Roderick Hindery tries to shed light on these tensions by contrasting them with impostors of authentic self-affirmation and altruism, by analysis of other-regard within creative individuation of the self, and by contrasting love for the few with love for the many. Love confirms others in their freedom, shuns propaganda and masks, assures others of its presence, and is ultimately confirmed not by mere declarations from others, but by each person's experience and practice from within. As in practical arts, the presence and meaning of love becomes validated and grasped not by words and reflections alone, but in the making of the connection.
St Thomas Aquinas interprets 'You should love your neighbour as yourself' as meaning that love for ourselves is the exemplar of love for others. Considering that "the love with which a man loves himself is the form and root of friendship" and quotes Aristotle that "the origin of friendly relations with others lies in our relations to ourselves," he concluded that though we are not bound to love others more than ourselves, we naturally seek the common good, the good of the whole, more than any private good, the good of a part. However, he thinks we should love God more than ourselves and our neighbours, and more than our bodily life—since the ultimate purpose of loving our neighbour is to share in eternal beatitude: a more desirable thing than bodily well being. In coining the word Altruism, as stated above, Comte was probably opposing this Thomistic doctrine, which is present in some theological schools within Catholicism.
Many biblical authors draw a strong connection between love of others and love of God. 1 John 4 states that for one to love God one must love his fellowman, and that hatred of one's fellowman is the same as hatred of God. Thomas Jay Oord has argued in several books that altruism is but one possible form of love. An altruistic action is not always a loving action. Oord defines altruism as acting for the other's good, and he agrees with feminists who note that sometimes love requires acting for one's own good when the other's demands undermine overall well-being.
German philosopher Max Scheler distinguishes two ways in which the strong can help the weak. One way is a sincere expression of Christian love, "motivated by a powerful feeling of security, strength, and inner salvation, of the invincible fullness of one’s own life and existence". Another way is merely "one of the many modern substitutes for love, ... nothing but the urge to turn away from oneself and to lose oneself in other people’s business." At its worst, Scheler says, "love for the small, the poor, the weak, and the oppressed is really disguised hatred, repressed envy, an impulse to detract, etc., directed against the opposite phenomena: wealth, strength, power, largesse."
In Islam, the concept 'ithaar' (إيثار) (altruism) is the notion of 'preferring others to oneself'. For Sufis, this means devotion to others through complete forgetfulness of one's own concerns, where concern for others is rooted to be a demand made by ALLAH on the human body, considered to be property of ALLAH alone. The importance lies in sacrifice for the sake of the greater good; Islam considers those practicing Eyaar as abiding by the highest degree of nobility. This is similar to the notion of chivalry, but unlike that European concept, in i'thar attention is focused on everything in existence. A constant concern for ALLAH (i.e. God) results in a careful attitude towards people, animals, and other things in this world. This concept was emphasized by Sufis of Islam like Rabia al-Adawiyya who paid attention to the difference between dedication to ALLAH (i.e. God) and dedication to people. Thirteenth-century Turkish Sufi poet Yunus Emre explained this philosophy as "Yaratılanı severiz, Yaratandan ötürü" or We love the creature, because of The Creator. For many Muslims, i'thar must be practiced as a religious obligation during specific Islamic holidays. However, i'thar is also still an Islamic ideal to which all Muslims should strive to adhere at all times.
Judaism defines altruism as the desired goal of creation. The famous Rabbi Abraham Isaac Kook stated that love is the most important attribute in humanity. This is defined as bestowal, or giving, which is the intention of altruism. This can be altruism towards humanity that leads to altruism towards the creator or God. Kabbalah defines God as the force of giving in existence. Rabbi Moshe Chaim Luzzatto in particular focused on the 'purpose of creation' and how the will of God was to bring creation into perfection and adhesion with this upper force.
Modern Kabbalah developed by Rabbi Yehuda Ashlag, in his writings about the future generation, focuses on how society could achieve an altruistic social framework. Ashlag proposed that such a framework is the purpose of creation, and everything that happens is to raise humanity to the level of altruism, love for one another. Ashlag focused on society and its relation to divinity.
Altruism is essential to the Sikh religion. The central faith in Sikhism is that the greatest deed any one can do is to imbibe and live the godly qualities like love, affection, sacrifice, patience, harmony, truthfulness. The concept of "seva," or selfless service to the community for its own sake is an important concept in Sikhism.
The fifth Nanak, Guru Arjun Dev, sacrificed his life to uphold 22 carats of pure truth, the greatest gift to humanity, the Guru Granth. The ninth Guru, Tegh Bahadur, sacrificed his head to protect weak and defenseless people against atrocity. In the late seventeenth century, Guru Gobind Singh Ji (the tenth guru in Sikhism), was in war with the Mughal rulers to protect the people of different faiths when a fellow Sikh, Bhai Kanhaiya, attended the troops of the enemy. He gave water to both friends and foes who were wounded on the battlefield. Some of the enemy began to fight again and some Sikh warriors were annoyed by Bhai Kanhaiya as he was helping their enemy. Sikh soldiers brought Bhai Kanhaiya before Guru Gobind Singh Ji, and complained of his action that they considered counter-productive to their struggle on the battlefield."What were you doing, and why?" asked the Guru. "I was giving water to the wounded because I saw your face in all of them," replied Bhai Kanhaiya. The Guru responded, "Then you should also give them ointment to heal their wounds. You were practicing what you were coached in the house of the Guru."
It was under the tutelage of the Guru that Bhai Kanhaiya subsequently founded a volunteer corps for altruism. This volunteer corps still to date is engaged in doing good to others and trains new volunteering recruits for doing the same.
In Hinduism Selflessness (Atmatyag), Love (Prema), Kindness (Daya) and Forgiveness (Kshama) are considered as the highest acts of humanity or "Manushyattva". Giving alms to the beggers or poor people is considered as a divine act or "Punya" and Hindus believe it will free their souls from guilt or "Paapa" and will led them to heaven or "Swarga" in afterlife. Altruism is also the central act of various Hindu mythology and religious poems and songs.
Swami Vivekananda, the legendary Hindu monk, has said -"Jive prem kare jeijon, Seijon sebiche Iswar" (Whoever loves any living being, is serving god.). Mass donation of clothes to poor people (Vastraseva), or blood donation camp or mass food donation (Annaseva) for poor people is common in various Hindu religious ceremonies.
Swami Sivananda, an Advaita scholar, reiterates the views in his commentary synthesising Vedanta views on the Brahma Sutras, a Vedantic text. In his commentary on Chapter 3 of the Brahma Sutras, Sivananda notes that karma is insentient and short-lived, and ceases to exist as soon as a deed is executed. Hence, karma cannot bestow the fruits of actions at a future date according to one's merit. Furthermore, one cannot argue that karma generates apurva or punya, which gives fruit. Since apurva is non-sentient, it cannot act unless moved by an intelligent being such as a god. It cannot independently bestow reward or punishment.
However the very well known and popular text, the Bhagavad Gita supports the doctrine of karma yoga (achieving oneness with God through action) & "nishkaama karma" or action without expectation / desire for personal gain which can be said to encompass altruism. Altruistic acts are generally celebrated and very well received in Hindu literature and is central to Hindu morality.
There exists a wide range of philosophical views on humans' obligations or motivations to act altruistically. Proponents of ethical altruism maintain that individuals are morally obligated to act altruistically. The opposing view is ethical egoism, which maintains that moral agents should always act in their own self-interest. Both ethical altruism and ethical egoism contrast with utilitarianism, which maintains that each agent should act in order to maximise the efficacy of their function and the benefit to both themselves and their co-inhabitants.
A related concept in descriptive ethics is psychological egoism, the thesis that humans always act in their own self-interest and that true altruism is impossible. Rational egoism is the view that rationality consists in acting in one's self-interest (without specifying how this affects one's moral obligations).
Effective altruism is a philosophy and social movement that uses evidence and reasoning to determine the most effective ways to benefit others. Effective altruism encourages individuals to consider all causes and actions and to act in the way that brings about the greatest positive impact, based upon their values. It is the broad, evidence-based and cause-neutral approach that distinguishes effective altruism from traditional altruism or charity. Effective altruism is part of the larger movement towards evidence-based practices.
While a substantial proportion of effective altruists have focused on the nonprofit sector, the philosophy of effective altruism applies more broadly to prioritizing the scientific projects, companies, and policy initiatives which can be estimated to save lives, help people, or otherwise have the biggest benefit. People associated with the movement include philosopher Peter Singer, Facebook cofounder Dustin Moskovitz, Cari Tuna, Ben Delo, Oxford-based researchers William MacAskill and Toby Ord, professional poker player Liv Boeree, and writer Jacy Reese.
