Amelia notices her elderly neighbour struggling with their shopping and lends them a hand. Mo decides to start volunteering for a local animal shelter after seeing a ‘help wanted’ ad. Alexis has been donating blood twice a year since they heard it was in such short supply.  

These are all examples, of behaviours that put the well-being of others first – otherwise known as altruism.  

Altruism is a principle and practice that concerns the motivation and desire to positively affect another being for their own sake. Amelia’s act is altruistic because she wishes to alleviate some suffering from her neighbour, Mo’s because he wishes to do the same for the animals and shelter workers, and Alexis’ because they wish to do the same to dozens of strangers. 

Crucially, motivation is what is key in altruism.  

If Alexis only donates blood because they really want the free food, then they’re not acting altruistically. Even though the blood is still being donated, even though lives are still being saved, even though the act itself is still good. If their motivation comes from self-interest alone, then the act lacks the other-directedness or selflessness of altruism. Likewise, if Mo’s motivation actually comes from wanting to look good to his partner, or if Amelia’s motivation comes from wanting to be put in her neighbour’s will, their actions are no longer altruistic. 

This is because altruism is characterised as the opposite of selfishness. Rather than prioritising themself, the altruist will be concerned with the well-being of others. However, actions do remain altruistic even if there are mixed motives.  

Consider Amelia again. She might truly care for her elderly neighbour. Maybe it’s even a relative or a good family friend. Nevertheless, part of her motivation for helping might also be the potential to gain an inheritance. While this self-interest seems at odds with altruism, so long as her altruistic motive (genuine care and compassion) also remains then the act can still be considered altruistic, though it is sometimes referred to as “weak” altruism. 

Altruism can (and should) also be understood separately from self-sacrifice. Altruism needn’t be self-sacrificial, though it is often thought of in that way. Altruistic behaviours can often involve little or no effort and still benefit others, like someone giving away their concert ticket because they can no longer attend.  

How much is enough? 

There is a general idea that everyone should be altruistic in some ways at some times; though it’s unclear to what extent this is a moral responsibility. 

Aristotle, in his discussions of eudaimonia, speaks of loving others for their own sake. So, it could be argued that in pursuit of eudaimonia, we have a responsibility to be altruistic at least to the extent that we embody the virtues of care and compassion.  

Another more common idea is the Golden Rule: treat others as you would like to be treated. Although this maxim, or variations of it, is often related to Christianity, it actually dates at least as far back as Ancient Egypt and has arisen in countless different societies and cultures throughout history. While there is a hint of self-interest in the reciprocity, the Golden Rule ultimately encourages us to be altruistic by appealing to empathy. 

We can find this kind of reasoning in other everyday examples as well. If someone gives up their seat for a pregnant person on a train, it’s likely that they’re being altruistic. Part of their reasoning might be similar to the Golden Rule: if they were pregnant, they’d want someone to give up a seat for them to rest.  

Common altruistic acts often occur because, consciously or unconsciously, we empathise with the position of others. 

Effective Altruism 

So far, we have been describing altruism and some other concepts that steer us toward it. However, here is an ethical theory that has many strong things to say about our altruistic obligations and that is consequentialism (concern for the outcomes of our actions).  

Given that, consequentialism can lead us to arguments that altruism is a moral obligation in many circumstances, especially when the actions are of no or little cost to us, since the outcomes are inherently positive.  

For example, Australian philosopher Peter Singer has written extensively on our ethical obligations to donate to charity. He argues that most people should help others because most people are in a position where they can do a lot for significantly less fortunate people with relatively little effort. This might look different for different people – it could be donating clothes, giving to charity, volunteering, signing petitions. Whatever it is, the type of help isn’t necessarily demanding (donating clothes) and can be proportional (donating relative to your income).  

One philosophical and social movement that heavily emphasises this consequentialist outlook is effective altruism, co-founded by Singer, and philosophers Toby Ord and Will MacAskill. 

The effective altruist’s argument is that it’s not good enough just to be altruistic; we must also make efforts to ensure that our good deeds are as impactful as possible through evidence-based research and reasoning. 

Stemming from the empirical foundation, this movement takes a seemingly radical stance on impartiality and the extent of our ethical obligations to help others. Much of this reasoning mirrors a principle outlined by Singer in his 1972 article, “Famine, Affluence and Morality”:  

“If it is in our power to prevent something very bad from happening, without thereby sacrificing anything morally significant, we ought, morally, to do it.” 

This seems like a reasonable statement to many people, but effective altruists argue that what follows from it is much more than our day-to-day incidental kindness. What is morally required of us is much stronger, given most people’s relative position to the world’s worst-off. For example, Toby Ord uses this kind of reasoning to encourage people to commit to donating at least 10% of their income to charity through his organisation “Giving What We Can”.  

Effective altruists generally also encourage prioritising the interests of future generations and other sentient beings, like non-human animals, as well as emphasising the need to prioritise charity in efficient ways, which often means donating to causes that seem distant or removed from the individual’s own life. 

While reasons for and extent of altruistic behaviour can vary, ethics tells us that it’s something we should be concerned with. Whether you’re a Platonist who values kindness, or a consequentialist who cares about the greater good, ethics encourages us to think about the role of altruism in our lives and consider when and how we can help others.
