The drowning child: helping distant people is a duty

The drowning child (Singer's pond)

Peter Singer born 1946If we can prevent something very bad without sacrificing anything of comparable importance, we ought to, even for a distant stranger.

What it claims

Affluent people ought to give to relieve famine. It is not charity, which one may or may not do: not giving is wrong.

Why

If we can prevent something very bad without comparable sacrifice, we must: distance changes nothing.

The same idea through history

Thomas Aquinas1270In the Summa Theologiae (II-II, question 66, article 7), whatever a man has in superabundance is owed, by natural right, to the poor for their sustenance. Singer quotes this passage himself to show that his conclusion is not so new.

Peter Singer1972During the 1971 Bengal famine, he compares the distant refugee to a child drowning in a shallow pond: we must save the child, even if we get our clothes muddy. So giving is not charity, it is a duty.

Peter Unger1996Living High and Letting Die: he compares a man who refuses to drive an injured person to hospital so as not to stain the seats of his fine car, and another who throws away a UNICEF letter asking for 100 dollars. We condemn the first and excuse the second; for Unger, our intuitions are wrong, the two failings are on a par.

Peter Singer2009The Life You Can Save retells the pond for the general public, answers the usual objections and proposes a realistic scale of giving, a few per cent of income, rising with wealth.

In short

"The drowning child: helping distant people is a duty" is an argument by Peter Singer ("Famine, Affluence, and Morality", Philosophy and Public Affairs, 1972, 1972) on the question "What makes something right?" (answer: consequences). Its claim: Affluent people ought to give to relieve famine. It is not charity, which one may or may not do: not giving is wrong. According to AskPhilosophy's logic check (Z3 solver), the argument is valid only if one grants a premise the author leaves unstated (P4). AskPhilosophy presents 3 objections, 3 of them with a documented reply, and the original text behind each premise, checked word for word.

Valid with an implicit premise

You walk past a shallow pond and see a small child drowning. You can wade in and pull the child out; you will ruin your shoes and clothes, that is all. Almost everyone says you must do it, and that walking on would be monstrous. Peter Singer was writing in 1971, during the Bengal famine, when millions of refugees lacked food and medical care. His question is simple: what difference is there between the child in the pond and a child starving on the other side of the world, when a modest donation would be enough to help? If there is none, giving is not an extra act of generosity: not giving is a wrong.

If you accept every premise, logic forces you to accept the conclusion. So the debate is about the premises.

Checked by a logic solver: the premises cannot all be true while the conclusion is false.
Without the implicit premise: Without P4, the computer finds a world where famine is very bad, where giving prevents it without great sacrifice, where distance and numbers do not count, but where some other difference releases us from the duty: for example, the child in the pond is right in front of me and depends on me alone, whereas famine is first of all the responsibility of governments. Several objections turn on a difference of this kind.

Valid with P4. P1 and P5 say that famine is very bad and that a donation prevents it without great sacrifice: so principle P2 applies, unless something releases us from the duty. P3 says that neither distance nor numbers release us; the hidden premise P4 adds that there is no other difference. The debate is about P2 (does the principle demand too much? Wolf), P3 and P4 (does distance really matter? Kamm) and P5 (does aid really save lives? Deaton).

Analogy. A classmate collapses in the playground and you are the only one who can call for help on your phone: you must do it, even if it makes you miss the start of the film. Singer asks: what if the classmate were a thousand kilometres away, and your call still cost you just as little? For him, the answer must be the same.

Objections

Each objection is a conversation: click to see who replies and where the debate stands.

Susan Wolf (the demandingness objection) 1982 · attacks premise 2

Taken seriously, the principle never stops: as long as there is a child left to save, every hour and every euro should go to it. One would become a "moral saint", who no longer reads novels, plays an instrument or works on their tennis backhand. Yet such a life is neither enviable nor even a reasonable ideal. A morality that demands this asks too much. (Bernard Williams had already blamed utilitarianism, in 1973, for forgetting that each person has their own life projects.)

Singer replies

Peter Singer 1972 · Singer's anticipated reply (1972)

Singer sees the objection coming in 1972: his principle does require working full time to relieve great suffering, as long as there is any. He cannot see why this should be a criticism of his reasoning rather than a criticism of our habits. He adds that the strong version of the principle (nothing of comparable importance) seems to him the correct one; the moderate version (nothing morally significant) only serves to show that even it already requires a great change in how we live.

Peter Singer 2009 · Singer, The Life You Can Save (2009)

In his book for the general public, Singer keeps the same thesis in principle, but proposes asking publicly for much less: a scale of giving of a few per cent of income, rising with wealth. A standard most people can follow will save more lives than an ideal almost nobody reaches.

The debate goes on (our summary) The debate continues. For Wolf, the problem is not only the amount to give: it is the idea that one should always be as moral as possible, at the expense of everything else. For Singer, our intuitions about what is "too demanding" are mostly those of people living in affluence. Note: the moderate version of the principle, which is enough for the argument, largely escapes the objection, since it does not require sacrificing what has real moral importance (one's family, one's essential projects). The question remains what counts as "important", and Singer grants that this is debatable.

Frances Kamm (does distance matter?) 1999 · attacks premise 3

Singer asserts too quickly that distance does not matter. By carefully comparing cases that differ only in distance, Kamm finds that we often judge the obligation to help someone near us to be stronger than to help a distant stranger in the same distress. For her, proximity creates a special responsibility: it is not just a trick of psychology. This does not mean we owe distant people nothing, but the pond argument does not carry over unchanged to Bengal.

Singer replies

Peter Singer 1972 · Singer's anticipated reply (1972)

Someone being near us makes it more likely that we will help them, but does not show that we ought to help them rather than someone further away. If we accept a principle of impartiality or equality, we cannot discriminate against someone merely because they are far away. The only good reason to help those close by first would be knowing better how to help them; but aid organisations on the ground have almost erased that difference.

The debate goes on (our summary) Singer's reply was written before Kamm and is about psychology (we help those we see more willingly); Kamm, for her part, holds that our considered judgements, not just our reflexes, give weight to distance. The disagreement is about method: should we trust intuitions about precise cases (Kamm) or correct them with a principle of impartiality (Singer, Unger)? Even Kamm grants that the duty to help distant people exists; the debate is about its strength.

Angus Deaton (the effectiveness of aid) 2015 · attacks premise 5

The economist Angus Deaton (Nobel prize 2015) challenges the fact everything rests on: a donation does not save a life as simply as pulling a child out of the water. Children are not dying for lack of a few thousand dollars; development is first of all a political problem. Foreign aid can even strengthen governments that oppress their people, by sparing them from having to answer to them. He already argued this in The Great Escape (2013).

Singer replies

Peter Singer 2015 · Singer's reply (Boston Review, 2015)

Deaton himself grants that aid against diseases such as AIDS or smallpox is justified. Studies of what works are recent and improving. And if another strategy, such as campaigning for large political reforms, does more good, effective altruists will adopt it: you do not refute the idea of helping as well as possible by showing one could help better. Even when we cannot cure the causes of poverty, treating its effects saves lives.

The debate goes on (our summary) Both sides agree on the principle (if we can save a life at little cost, we ought to); they disagree on the facts: how many lives does a donation really save, and at what cost to the institutions of the countries helped? It is a question of economics as much as of philosophy. Note: Deaton's objection does not make aid optional; it only changes its form (for him: acting on the policies of rich countries, against the arms trade and unfair trade deals, for research on tropical diseases).
