Altruism: Is It Real?

A car is turned over, set ablaze. A passerby spots the driver still trapped inside. The driver has little time left, soon to be engulfed by the flames. The passerby sprints, from amidst onlookers, to the fiery wreck, managing to pull the driver out to safety but at his own grave peril. The ‘good Samaritan’ waits for the first responders to arrive, while comforting the semiconscious driver, and then leaves without giving his name or waiting for a thank-you.

Were the actions of the passerby those of altruism? Most people would immediately answer that question affirmatively. After all, the passerby selflessly put himself at risk, to aid a stranger. He seemed to disregard his own welfare. There was no expectation of reward or adulation or reciprocity. And he could just as readily have stood impassively watching or gone on his way to office or home, as everyone else was doing. Still, might the passerby’s self-interested motivation and intent have been as simple and basic as feeling good about having performed the deed? Or might the passerby’s actions have been prompted irresistibly by instinct, based on his brain’s physiology? Or is yet another explanation plausible?

Some people deny that altruism exists at all. Altruism is impossible, they say. They contend that all actions are taken solely to satisfy some selfish need or urge, and that the fact such actions might benefit someone else is incidental — or at least self-serving. The philosopher Ayn Rand starkly warned against what she saw, in fact, as the purported deceit of altruism: ‘If any civilization is to survive, it is the morality of altruism that people have to reject’.

One name for such beliefs is ‘psychological egoism’: the view that deep down, people are always motivated by what they perceive to be in their own self-interest. That is, voluntarily helping others is only a subsidiary consequence of actions taken, where assistance rendered is impelled singularly by wanting to benefit ourselves. We relish feeling the glow of doing good. This overriding self-interest remains valid even when the actions taken might be accompanied by detriment to the doer, divorced from the urge to ‘help’. In short, no acts, it is thought, are designed solely to benefit someone else. There’s always the sense of gratification for having helped. It’s an unflattering explanation of human nature and behaviour.

Against this, other people subscribe to so-called ‘pure’ or ‘strong’ altruism’. This is a model of behaviour where acts of altruism are wholly selfless, undertaken uniquely to benefit someone else. There is no expectation of either an intrinsic or extrinsic reward, or of personal gratification. That is, every ‘good deed’ — including those where there’s a noble sacrifice (possibly even injury or death to the doer) — is unswervingly motivated by the desire to be of service to others. Martin Luther King’s words capture these sentiments, when he talks of the choice between ‘walking in the light of creative altruism or in the darkness of destructive selfishness’. A recent real-life example of self-sacrificial altruism was of a university professor who, losing his life in the process, blocked the door to his classroom in order to shield his students from the bullets of a rampaging shooter.

However, one characterisation of selflessness centers on utilitarian ideas about individuals deferring dispassionately to bettering the welfare of others, in the process, resisting their own self-interested wants and urgings. The definition of ‘others’ in this case may range from a single individual to family members, friends, associates, or larger community (the collective), importantly including people we don’t know and never will. It’s a more logic-based approach to supporting others’ wellbeing. Another approach centers on sympathy and kindheartedness, correlated to an intense response to the suffering and misfortune of others. Although there may always be the prospect of self-gain, here aiding others is based more in sentiment than reason, and hinges on the specialness of human connections. The 18th-century English philosopher Joseph Butler nicely parses this point about the balance between self-gain and selflessness, observing that: 

‘The satisfaction that accompanies good acts is itself not the motivation of the act; satisfaction is not the motive, but only the consequence.’

Thus far I have focused on ‘psychological altruism’, involving prosocial, empathic, compassionate behaviours such as providing aid and comfort in order to alleviate another person’s or a group’s suffering. Especially a total stranger’s woe, rather than the presumably simpler case of a relative’s or friend’s anguish. Taking in a migrant family, with no expected reward, is one example of this type of aid; volunteering as a doctor or nurse to work, say, in a remotely located Ebola or HIV treatment facility might be another. However, there may be at least another explanation for fathoming the human facility for altruistic deeds: the physiology of an individual’s brain.

Recent research, using brain imaging, claims to have found that those people with little to no empathy, compassion, or ability to recognize cues of others’ distress tend to have smaller-than-average amygdala regions. The worst-case example being psychopathy, resulting in those with this condition to act callously, insensitively, and disinterested in others’ welfare. People thus afflicted thereby are often unable to recognize others’ fear. In contrast, highly altruistic people tend to have amygdalas that are larger and more reactive than average. This kind of explanation in which ‘mind’ is reduced to ‘matter’ does, of course, bring into question whether free agency is essential to altruism. In the case of our hypothetical passerby, the one who rescues the driver from the burning car, it’s assumed that his amygdala would have had these same features. In this same vein, the affection people generally feel for their own children, along with a deep motivation to protect and do good for them, may seem to be ‘hard-wired’, further pointing to the role of brain physiology in altruism. This extends beyond just gene survival and evolutionary purposes.

Sigmund Freud pointed out that our motives, and the motives of others, are often veiled, and that we are in fact driven by parts of our minds that have agenda of which we are unaware. Perhaps, therefore, the difference between ‘pure altruism’ (if attainable) and what we might call ‘everyday altruism’ is more one of language and semantics, with little to no practical consequence as to the reality of altruism and beneficial outcomes.
