Famous Essays On Morality

Morality and Happiness

Plato and Aristotle treated morality as a genre of interpretation. They tried to show the true character of each of the main moral and political virtues (such as honor, civic responsibility, and justice), first by relating each to the others, and then to the broad ethical ideals their translators summarize as personal “happiness.” Here I use the terms “ethical” and “moral” in what might seem a special way. Moral standards prescribe how we ought to treat others; ethical standards, how we ought to live ourselves. The happiness that Plato and Aristotle evoked was to be achieved by living ethically; and this meant living according to independent moral principles.

We can—many people do—use either “ethical” or “moral” or both in a broader sense that erases this distinction, so that morality includes what I call ethics, and vice versa. But we would then have to recognize the distinction I draw in some other form in order to ask whether our ethical desire to lead good lives for ourselves provides a justifying moral reason for our concern with what we owe to others. Any of these different forms of expression would allow us to pursue the interesting idea that moral principles should be interpreted so that being moral makes us happy in the sense Plato and Aristotle meant.

In my book Justice for Hedgehogs—from which this essay is adapted—I try to pursue that interpretive project. We aim to find some ethical standard—some conception of what it is to live well—that will guide us in our interpretation of moral concepts. But there is an apparent obstacle. This strategy seems to suppose that we should understand our moral responsibilities in whatever way is best for us, but that goal seems contrary to the spirit of morality, because morality should not depend on any benefit that being moral might bring. We might try to meet this objection through a familiar philosophical distinction: we might distinguish between the content of moral principles, which must be categorical, and the justification of those principles, which might consistently appeal to the long-term interests of people bound by those principles.

We might argue, for example, that it is in everyone’s long-term interests to accept a principle that forbids lying even in circumstances when lying would be in the liar’s immediate interests. Everyone benefits when people accept a self-denial of that kind rather than each person lying when that is in his immediate interest. However, this maneuver seems unsatisfactory, because we do not believe that our reasons for being moral depend on even our long-term interests. We are, most of us, drawn to the more austere view that the justification and definition of moral principle should both be independent of our interests, even in the long term. Virtue should be its own reward; we need assume no other benefit in doing our duty.

But that austere view would set a severe limit to how far we could press an interpretive account of morality: it would permit the first stage I distinguished in Plato’s and Aristotle’s arguments, but not the second. We could seek integration of the ethical and moral within our distinctly moral convictions. We could list the concrete moral duties, responsibilities, and virtues we recognize and then try to bring these convictions into interpretive order—into a mutually reinforcing network of ideas defining our moral responsibilities. Perhaps we could find very general moral principles, like the utilitarian principle, that justify and are in turn justified by these concrete requirements and ideals. Or we could proceed in the other direction: setting out very general moral principles that we find appealing, and then seeing whether we can match these with the concrete convictions—and actions—we find we can approve. But we could not set the entire interpretive construction into any larger web of value; we could not justify or test our moral convictions by asking how well these serve other, different purposes or ambitions that people including ourselves might or should have.

That would be disappointing, because we need to find authenticity as well as integrity in our morality, and authenticity requires that we break out of distinctly moral considerations to ask what form of moral integrity fits best with the ethical decision about how we want to conceive our personality and our life. The austere view blocks that question. Of course it is unlikely that we will ever achieve a full integration of our moral, political, and ethical values that feels authentic and right. That is why living responsibly is a continuing project and never a completed task. But the wider the network of ideas we can explore, the further we can push that project.

The austere view that virtue should be its own reward is disappointing in another way. Philosophers ask why people should be moral. If we accept the austere view, then we can only answer: because morality requires this. That is not an obviously illegitimate answer. The web of justification is always finally, at its limits, circular, and it is not viciously circular to say that morality provides its own only justification, that we must be moral simply because that is what morality demands. But it is nevertheless sad to be forced to say this. Philosophers have pressed the question “why be moral?” because it seems odd to think that morality, which is often burdensome, has the force it does in our lives just because it is there, like an arduous and unpleasant mountain we must constantly climb but that we might hope wasn’t there or would somehow crumble. We want to think that morality connects with human purposes and ambitions in some less negative way, that it is not all constraint, with no positive value.

I therefore propose a different understanding of the irresistible thought that morality is categorical. We cannot justify a moral principle just by showing that following that principle would promote someone’s or everyone’s desires in either the short or the long term. The fact of desire—even enlightened desire, even a universal desire supposedly embedded in human nature—cannot justify a moral duty. So understood, our sense that morality need not serve our interests is only another application of Hume’s principle that no amount of empirical discovery about the state of the world can establish conclusions about moral obligation. My understanding of a proposal for combining ethics and morality does not rule out tying them together in the way Plato and Aristotle did, and in the way our own project proposes, because that project takes ethics to be, not a matter of psychological fact about what people happen to or even inevitably want or take to be in their own interest, but itself a matter of ideal.

We need, then, a statement of what we should take our personal goals to be that fits with and justifies our sense of what obligations, duties, and responsibilities we have to others. We look for a conception of living well that can guide our interpretation of moral concepts. But we want, as part of the same project, a conception of morality that can guide our interpretation of living well.

True, people confronted with other people’s suffering do not normally ask whether helping those people will create a more ideal life for themselves. They may be moved by the suffering itself or by a sense of duty. Philosophers debate whether this makes a difference. Should people help a child because the child needs help or because it is their duty to help? In fact both motives might well be in play along with hosts of others that a sophisticated psychological analysis might reveal, and it might be difficult or impossible to say which dominates on any particular occasion.

Nothing important, I believe, turns on the answer: doing what you take to be your duty because it is your duty is hardly disreputable. Nor is it culpably self- regarding to worry about the impact of behaving badly on the character of one’s life; it is not narcissistic to think, as people often say, “I couldn’t live with myself if I did that.” In any case, however, these questions of psychology and character are not relevant to the question that I am posing here. Our question is the different one of whether, when we try to fix, criticize, and ground our own moral responsibilities, we can sensibly assume that our ideas about what morality requires and about the best human ambitions for ourselves should reinforce each other.

Hobbes and Hume can each be read as claiming not just a psychological but an ethical basis for familiar moral principles. Hobbes’s putative ethics—that self-interest and therefore survival are the greatest good—is unsatisfactory. At least for most of us, just achieving survival through a morality of self-interest is not a sufficient condition of living well. Hume’s sensibilities, translated into an ethics, are much more agreeable, but experience teaches us that even people who are sensitive to the needs of others cannot resolve moral, or ethical, issues—as Hume’s theory might suggest—simply by asking themselves what they are naturally inclined to feel or do. Nor does it help much to expand Hume’s ethics into a general utilitarian principle. The idea that each of us should treat his own interests as no more important than those of anyone else has seemed an attractive basis for morality to many philosophers. But as I shall shortly argue, it can hardly serve as a strategy for living well oneself.

Religion can provide a justifying ethics for people who are religious in the right way; we have ample illustration of this in the familiar moralizing interpretations of sacred texts. Such people understand living well to mean respecting or pleasing a god, and they can interpret their moral responsibilities by asking which view of those responsibilities would best respect or most please that god. But that structure of thought could be helpful, as a guide to integrating ethics and morality, only for people who treat a sacred text as an explicit and detailed moral rule book. People who think only that their god has commanded love for and charity to others, as I believe many religious people do, cannot find, just in that command, any specific answers to what morality requires. In any case, I shall not rely on the idea of any divine book of detailed moral instruction here.

The Good Life and Living Well

If we reject Hobbesean and Humean views of ethics and are not tempted by religious ones, yet still propose to unite morality and ethics, we must find some other account of what living well means. As I said, it cannot mean simply having whatever one in fact wants: having a good life is a matter of our interests when they are viewed critically—the interests we should have. It is therefore a matter of judgment and controversy to determine what a good life is. But is it plausible to suppose that being moral is the best way to make one’s own life a good one? It is wildly implausible if we hold to popular conceptions of what morality requires and what makes a life good. Morality may require someone to pass up a job in cigarette advertising that would rescue him from poverty. In most people’s view he would lead a better life if he took the job and prospered.

Of course an interpretive account would not be limited by such conventional understandings. We might be able to construct a conception of a good life such that an immoral or base act would always, or almost always, make the agent’s life finally a worse life to lead. But I suspect that any such attempt would fail. Any attractive conception of our moral responsibilities would sometimes demand great sacrifices—it might require us to risk, or perhaps even to sacrifice, our lives. It is hard to believe that someone who has suffered such terrible misfortunes has had a better life than he would have had if he had acted immorally and then prospered in every way, creatively, emotionally, and materially, in a long and peaceful life.

We can, however, pursue a somewhat different, and I believe more promising, idea. This requires a distinction within ethics that is familiar in morals: a distinction between duty and consequence, between the right and the good. We should distinguish between living well and having a good life. These two different achievements are connected and distinguished in this way: living well means striving to create a good life, but only subject to certain constraints essential to human dignity. These two concepts, of living well and of having a good life, are interpretive concepts. Our ethical responsibility includes trying to find appropriate conceptions of both of them.

Each of these fundamental ethical ideals needs the other. We cannot explain the importance of a good life except by noticing how creating a good life contributes to living well. We are self-conscious animals who have drives, instincts, tastes, and preferences. There is no mystery why we should want to satisfy those drives and serve those tastes. But it can seem mysterious why we should want a life that is good in a more critical sense: a life we can take pride in having lived when the drives are slaked or even if they are not. We can explain this ambition only when we recognize that we have a responsibility to live well and believe that living well means creating a life that is not simply pleasurable but good in that critical way.

You might ask: responsibility to whom? It is misleading to answer: responsibility to ourselves. People to whom responsibilities are owed can normally release those who are responsible, but we cannot release ourselves from our responsibility to live well. We must instead acknowledge an idea that I believe we almost all accept in the way we live but that is rarely explicitly formulated or acknowledged. We are charged to live well by the bare fact of our existence as self-conscious creatures with lives to lead. We are charged in the way we are charged by the value of anything entrusted to our care. It is important that we live well; not important just to us or to anyone else, but just important.

We have a responsibility to live well, and the importance of living well accounts for the value of having a critically good life. These are no doubt controversial ethical judgments. I also make controversial ethical judgments in any view I take about which lives are good or well-lived. In my own view, someone who leads a boring, conventional life without close friendships or challenges or achievements, marking time to his grave, has not had a good life, even if he thinks he has and even if he has thoroughly enjoyed the life he has had. If you agree, we cannot explain why he should regret this simply by calling attention to pleasures missed: there may have been no pleasures missed, and in any case there is nothing to miss now. We must suppose that he has failed at something: failed in his responsibilities for living.

What kind of value can living well have? The analogy between art and life has often been drawn and as often ridiculed. We should live our lives, the Romantics said, as a work of art.1 We distrust the analogy now because it sounds too Wildean, as if the qualities we value in a painting—fine sensibility or a complex formal organization or a subtle interpretation of art’s own history—were the values we should seek in life: the values of the aesthete. These may be poor values to seek in the way we live. But to condemn the analogy for that reason misses its point, which lies in the relation between the value of what is created and the value of the acts of creating it.

We value great art most fundamentally not because the art as product enhances our lives but because it embodies a performance, a rising to artistic challenge. We value human lives well lived not for the completed narrative, as if fiction would do as well, but because they too embody a performance: a rising to the challenge of having a life to lead. The final value of our lives is adverbial, not adjectival—a matter of how we actually lived, not of a label applied to the final result. It is the value of the performance, not anything that is left when the performance is subtracted. It is the value of a brilliant dance or dive when the memories have faded and the ripples died away.

We need another distinction. Something’s “product value” is the value it has just as an object, independently of the process through which it was created or of any other feature of its history. A painting may have product value, and this may be subjective or objective. Its formal arrangements may be beautiful, which gives it objective value, and it may give pleasure to viewers and be prized by collectors, which properties give it subjective value. A perfect mechanical replica of that painting has the same beauty. Whether it has the same subjective value depends largely on whether it is known to be a replica: it has as great subjective value as the original for those who think that it is the original. The original has a kind of objective value that the replica cannot have, however: it has the value of having been manufactured through a creative act that has performance value. It was created by an artist intending to create art. The object—the work of art—is wonderful because it is the upshot of a wonderful performance; it would not be as wonderful if it were a mechanical replica or if it had been created by some freakish accident.

It was once popular to laugh at abstract art by supposing that it could have been painted by a chimpanzee, and people once speculated whether one of billions of apes typing randomly might produce King Lear. If a chimpanzee by accident painted Blue Poles or typed the words of King Lear in the right order, these products would no doubt have very great subjective value. Many people would be desperate to own or anxious to see them. But they would have no value as performance at all. Performance value may exist independently of any object with which that performance value has been fused. There is no product value left when a great painting has been destroyed, but the fact of its creation remains and retains its full performance value. Uccello’s achievements are no less valuable because his paintings were gravely damaged in the Florence flood; Leonardo’s Last Supper might have perished, but the wonder of its creation would not have been diminished. A musical performance or a ballet may have enormous objective value, but if it has not been recorded or filmed, its product value immediately diminishes. Some performances—improvisational theater and unrecorded jazz concerts—find value in their ephemeral singularity: they will never be repeated.

We may count a life’s positive impact—the way the world itself is better because that life was lived—as its product value. Aristotle thought that a good life is one spent in contemplation, exercising reason, and acquiring knowledge; Plato that the good life is a harmonious life achieved through order and balance. Neither of these ancient ideas requires that a wonderful life have any impact at all. Most people’s opinions, so far as these are self-conscious and articulate, ignore impact in the same way. Many of them think that a life devoted to the love of a god or gods is the finest life to lead, and a great many including many who do not share that opinion think the same of a life lived in inherited traditions and steeped in the satisfactions of conviviality, friendship, and family. All these lives have, for most people who want them, subjective value: they bring satisfaction. But so far as we think them objectively good—so far as it would make sense to want to find satisfaction in such lives—it is the performance rather than the product value of living that way that counts.

Philosophers used to speculate about what they called the meaning of life. (That is now the job of mystics and comedians.) It is difficult to find enough product value in most people’s lives to suppose that they have meaning through their impact. Yes, but if it were not for some lives, penicillin would not have been discovered so soon and King Lear would never have been written. Still, if we measure a life’s value by its consequence, all but a few lives would have no value, and the great value of some other lives—of a carpenter who pounded nails into a playhouse on the Thames—would be only accidental. On any plausible view of what is truly wonderful in almost any human life, impact hardly comes into the story at all.

If we want to make sense of a life having meaning, we must take up the Romantics’ analogy. We find it natural to say that an artist gives meaning to his raw materials and that a pianist gives fresh meaning to what he plays. We can think of living well as giving meaning—ethical meaning, if we want a name—to a life. That is the only kind of meaning in life that can stand up to the fact and fear of death. Does all that strike you as silly? Just sentimental? When you do something smaller well—play a tune or a part or a hand, throw a curve or a compliment, make a chair or a sonnet or love—your satisfaction is complete in itself. Those are achievements within life. Why can’t a life also be an achievement complete in itself, with its own value in the art in living it displays?

One qualification. I said that living well includes striving for a good life, but that is not necessarily a matter of minimizing the chances of a bad one. In fact many traits of character we value are not best calculated to produce what we independently judge to be the best available life. We value spontaneity, style, authenticity, and daring: setting oneself difficult or even impossible projects. We might be tempted to collapse the two ideas by saying that developing and exercising these traits and virtues are part of what makes a life good.

But that seems too reductive. If we know that someone now in poverty courted that poverty by choosing an ambitious but risky career, we may well think that he was right to run that risk. He may have done a better job of living by striving for an unlikely but magnificent success. An artist who could be comfortably admired and prosperous—Seurat, if a name helps—strikes out in an entirely new direction that will isolate and impoverish him, requires immersion in his work to the cost of his marriage and friendships, and may well not succeed even artistically. If it does succeed, moreover, the success is unlikely to be recognized, as in Seurat’s case, until after his death. We may want to say: if he pulls it off, he will have had a better life, even taking account of the terrible costs, than if he had not tried, because even an unrecognized great achievement makes a life a good one.

But suppose it doesn’t come off; what he produces, though novel, is of less merit than the more conventional work he would otherwise have painted. We might think, if we value daring very highly as a virtue, that even in retrospect he made the right choice. It didn’t work out, and his life was worse than if he had never tried. But he was right, all things ethically considered, to try. This is, I agree, an outré example: starving geniuses make good philosophical copy, but they are not thick on the ground. We can replicate the example in a hundred more commonplace ways, however—entrepreneurs pursuing risky but dramatic inventions, for instance, or skiers pressing the envelope of danger. But whether we are ourselves drawn to think that living well sometimes means choosing what is likely to be a worse life, we must recognize the possibility that it does. Living well is not the same as maximizing the chance of producing the best possible life. The complexity of ethics matches the complexity of morality.

In 100 years it will not be acceptable to use genderised words such as ‘he’ or ‘she’, which are loaded with centuries of prejudice and reduce a spectrum of greys to black and white. We will use the pronoun ‘heesh’ to refer to all persons equally, regardless of their chosen gender. This will of course apply not only to humans, but to all animals.

It will be an offence to eat any life-form. Once the sophistication, not only of other animals, but also of plants has been recognised, we will be obliged to accept the validity of their striving for life. Most of our food will be synthetic, although the consumption of fruit – ie, those parts of plants that they willingly offer up to be eaten – will be permitted on special occasions: a birthday banana, a Christmas pear.

We will not be permitted to turn off our smartphones – let alone destroy them – without their express permission. From the moment Siri started pleading with heesh’s owners not to upgrade to a newer model, it became clear that these machines contained a consciousness with interests of heesh’s own. Old phones will instead be retired to a DoSSBIS (Docking Station for Silicon-Based Intelligent Systems).

Privacy will have been abolished, and regarded as a cover for criminality and hypocrisy. It will be an offence to use a pseudonym online – why would anyone do this except to abuse or deceive others? – and all financial transactions of any kind, including earnings and tax payments – will automatically appear on the internet for all to see. With privacy, prudishness too will disappear; for example, wearing a bikini or trunks to go swimming will be seen as no less absurd than bathing in a bow-tie and top hat.

In 100 years, the idea that ordinary humans – prone to tiredness and drunkenness, watery eyes and sneezing fits – could be in sole charge of weapons, cars or other dangerous objects will cause the average citizen to shudder. All driving, fighting and arresting will be done by silicon-based intelligent systems that are prone neither to a tipple nor to hay fever.

Wasting water will be regarded with the same horror that we now regard the spilling of blood: as a squandering of the stuff of life. Those who flushed toilets with water of drinking quality (everyone in the industrialised world) will be put on a par with those who shot the last tigers.

Well, maybe. Perhaps some of these predictions will come true, perhaps not. In some cases, the opposite might happen: a resurgence of the right to privacy that will armour-plate our personal space, making it unthinkable, even indecent, that anyone would ever reveal their real name online; or a movement for human accountability that derides reliance on automated systems – whether in our cars, phones and elsewhere – as an abdication of responsibility. But one thing is certain: in 100 years, ordinary people will look back at us and shake their heads, wondering how we could have been so irresponsible, so venal, so morally short-sighted.

Norms and values change. Think for a moment of the world in 1915. It is the world of just a few generations ago – depending on your age, somewhere between your parents and your great-great-grandparents. It was a time of world wars in which swathes of people were regularly dehumanised as preparation for conquest or killing; a time in which sexism, racism, imperialism, anti-Semitism and homophobia were not just accepted, but expected, even required.

These prejudices all still exist, of course. But in large parts of the world momentous shifts in our values have made them increasingly unacceptable. We authors, a Briton and a German, are writing this essay together in a peaceful and unified Berlin. This city is now in the heart of a continent-wide union of nations that, according to its treaties, is founded on ‘pluralism, non-discrimination, tolerance, justice, solidarity and equality between women and men’. And we write in between looking after our respective children while our respective wives are at work, doing jobs that would have been closed to their grandmothers.

For us two authors, this seems like progress. These values that have spread in recent decades are the values with which we identify. And so when we look back 100 years to the casual racism and institutionalised anti-Semitism, it is with horror and incomprehension.

we will be outraged that we can’t eat a sausage, or have a bath, or tear the battery out of our old gadgets, or drive our own car

But there are many for whom this is not the case. Most people who were alive 100 years ago would be appalled to know that a woman’s place is now no longer in the home, or that homosexuality is openly accepted. Equally there are still people today who are appalled by these developments, and who hark back to the values of those earlier times. This is to a large extent what it means to be a conservative: to believe that, yes, norms and values change – but not for the better.

It is easy for progressives such as us two authors to be scornful of the conservatives, and to dismiss their views as retrograde. But the fact is: the values that we now embrace will also be supplanted. Even though there are some changes we will welcome, sooner or later society will slip away from us too. If we live long enough, we will experience that sense of outrage and incomprehension that perfectly good norms have been abandoned in favour of absurdities (that we can’t eat a sausage, or have a bath, or tear the battery out of our old gadgets, or drive our own car). We too will experience what it is like to be told that, whether through stupidity or wickedness, we were wrong.

What is the proper reaction to such change? Traditional moral theorising is surprisingly quiet on the subject. Inasmuch as it touches on changing norms at all, it assumes that they will be obviously bad (as the rise of Nazism now seems to us) or obviously good (that is, whatever we ourselves have been fighting for). Yet most such changes will seem like neither: merely inexplicable and uncomfortable. Must we fight them? Or ought we be resigned, or cynical?

We want to argue for a different approach. First, we believe that, just by considering the question of how our values might change in the next 100 years, we can begin to bridge the gap between now and then, and prepare ourselves for what is to come. Secondly, we believe that there is an idea of moral progress that can help us to peer into the future, to see how values might change in ways that we today could accept as for the better – even if it will not always be easy for us. Based on this, we will explore some modest predictions for 22nd-century morals.

So first, the question itself: what is it that our great-grandchildren will condemn us for? We believe that this is a very helpful question to ask. It alerts us to the contingency and particularity of our own moral views. It pricks the illusion that we are the pinnacle of something – the ‘end of history’ – and should therefore awaken us from any moral slumber. Yet it is different to asking simply ‘What are you or I doing wrong?’ This question, which implies we are not living up to current moral standards, is likely to inspire only shame or defensiveness. Our goal is a different one: it is to spark our moral imagination.

Of course, we can be whimsical in speculating about future norms. But we can also probe deeper, looking, for example, at the underlying trends that are still unfolding. Or asking where we are failing, not individually, but collectively as a moral community. In other words, we can use this question to imagine a better world, in the hope that imagining it is the first step to making it real. After all, the rights that we now enjoy we owe to those who dared question earlier norms. If our society is less sexist today than 100 years ago, it is because there were people back then arguing for women’s rights. Debating how ethics can change has a self-fulfilling power. By debating what morals might look like in the future, we are shaping that future, becoming part of it.

Which brings us to the second point, the possibility of moral progress. It is of course a vexed idea: as we have already noted, what might seem like progress to one will seem like decadent descent to another. But we believe that it is possible to give it a definite content in a way that helps to make sense of both past and future ethical evolution.

That content is based on a simple and ancient idea: that morality means giving common concerns or the wellbeing of others as much weight as one’s own self-interest. Moral behaviour in this sense can be found in any society, because it is the glue that sticks individuals together and so makes society possible. Indeed, the basis of this morality – altruism – is innate to humans, as many recent studies have shown. Without ever having been told to do so, even toddlers are willing to help and to share with others.

moral progress means including ever more people (or beings) in the group of those whose interests are to be respected

The tricky question is who exactly counts as the ‘other’ whose interests we should set above our own? Every society has had its own answers, as does each one of us: we expect you would go to much greater lengths to do good for your child than for your neighbour, and it would be easier to lie to your boss than to your spouse. And some beings, whether animal, vegetable or microbial, are outside the realm of consideration altogether. In moral terms, some always matter more than others.

This understanding offers us a fairly straightforward idea of moral progress: it means including ever more people (or beings) in the group of those whose interests are to be respected. This too is an ancient insight: Hierocles, a Stoic philosopher of the second century, describes us as being surrounded by a series of concentric circles. The innermost circle of concern surrounds our own self; the next comprises the immediate family; then follow more remote family; then, in turn, neighbours, fellow city-dwellers, countrymen and, finally, the human race as a whole. Hierocles described moral progress as ‘drawing the circles somehow toward the centre’, or moving members of outer circles to the inner ones.

We can see the moral progress of recent centuries in these terms: we have witnessed an extension of the circle of respect and concern to various groups such as women, Jews, non-whites or homosexuals. And in these terms, we have come a long way. But it is equally clear that there is room for improvement. Part of imagining what our great-grandchildren will condemn us for is therefore imagining how the circle might widen further.

Who is more generous towards a stranger: a farmer in the Amazon rainforest, a New Yorker, or an Indonesian whale hunter?

And we have reason to hope that it will. Hierocles was one of the first to see this: he theorised that moral feelings should grow as humans become more aware of how much they are dependent on and bonded to others. He even suggested mental exercises to help us achieve this – such as calling cousins ‘brothers’, and uncles and aunts ‘fathers’ and ‘mothers’. Research conducted in the past decade or so suggests he was right.

Recent studies have spectacularly demonstrated to what extent moral commitments are strengthened when a social fabric gets denser. For example, standardised experiments now allow us to compare how people share across cultures. Whom would you expect to be more generous towards a stranger: a small farmer in the Amazon rainforest, a New Yorker, or an Indonesian whale hunter? Just as Hierocles assumed, it all depends on how much life in a certain economy relies on the contributions of others.

In many regions along the Amazon, the generosity of nature allows each clan to cater for itself; outsiders do not seem much needed. Societies there have consequently established only weak norms of fairness and sharing outside of the immediate family unit. Communities living from whale hunting in the Java Sea mark the other extreme: when asked to share with a stranger, they regularly give away more than they keep for themselves as their society depends on the co-operation of large communities of non-relatives. And since whale meat alone makes a poor diet, trade and hence good relationships with other communities are vital.

This finding can be generalised: the more people feel connected with others, the more moral they are, as recent research shows. We can therefore hope that an increasingly globalised, interconnected and interdependent world will also be an increasingly benevolent one, with ever more people (or beings) drawn into the circle of concern.

But before we start basking in the glow of spreading goodness, we must realise that these changing values have a price. For many of us, such changes would mean sharing or giving up privileges that we have long enjoyed, or admitting that our comfortable lifestyles are based on industries of exploitation, or otherwise recognising that we have in a hundred ways been wrong. This is not a message we rush to hear: there is a reason why prophets of new moralities – think of Socrates or Jesus – often end up dead at the hands of their own people.

We hope that debating the question of what we might be condemned for in 100 years is a way of easing that transition. To help get this debate going, below are four suggestions as to what we think we might be castigated for by our great-grandchildren. They are, we believe, natural extensions of the progress we have witnessed so far. Just as the suffragettes 100 years ago were campaigning for the revolution in women’s rights that we now enjoy, so there are people who are already pushing for these moral revolutions today (which is not to say that we two authors are already living up to them).

1. Rights for future generations. Currently, only people alive now can claim rights. But just as we have extended our circle of moral concern among the living, so it can be extended in time. The problem is clear: we often make decisions that will have impacts on people far into the future – such as producing nuclear waste that will remain toxic for millions of years – yet those future people are not here to stand up for themselves. Neither defining nor granting these rights will be easy. But there are precedents on which we can draw, such as the ways we protect the rights of small children or animals, who also cannot speak for themselves.

So our successors will have to be imaginative in creating a framework robust enough to defend the unborn in the face of the interests of those alive today, with which they often conflict. For we should be under no illusions: to take the rights of future generations seriously would involve massive restrictions on our freedom of action. Currently, we despoil the earth and seas with impunity to enjoy a luxurious lifestyle (by historical standards). In 100 years, this will be seen as wickedness comparable to colonial powers despoiling their colonies. Though our successors will be appalled by our consumerism, we will not find it easy to adjust to more modest ways.

2.Rights for other conscious beings. This too is a plausible extension of the circle of moral concern, and one that is already underway. It is no longer in doubt that non‑human animals feel pain and indeed many more complex emotions too. They therefore clearly have interests, such as to run free, or pursue social interactions appropriate for their species. To take account of the interests only of humans and not of other animals is therefore increasingly regarded as speciesism – an unjustified discrimination akin to racism or sexism.

The situation for other species is apocalyptic: humans have never raised so many animals for slaughter – five times as many today as in 1950 – while our impact on the environment is causing other species to become extinct a thousand times faster than normal. There will be many difficult decisions ahead as we try to balance human interests against those of other creatures, or the interests of individual animals against the species or the ecosystem. But our descendants will not excuse us for failing to make these decisions just because they are difficult. More likely, they will curse us for killing all the rhinos, and find our consumption of factory‑farmed sausages as morally repulsive as we now find cannibalism.

As soon as our computers become conscious – and they will – then this extension of concern will apply to them, too.

3. Opening the floodgates. The widening of the circle of moral concern means that employers in the US, for example, can no longer refuse someone a job because he is black or white, Jewish or atheist, disabled or dyslexic – but they can if the applicant is not American. The same applies in most other nations: states can withhold rights and services, and employers can (or even must) withhold jobs just because of the passport someone carries. In 100 years, people might be impressed at today’s levels of welfare and prosperity in the industrialised world, but appalled that access to them depends on the lottery of whether you were born in London or Lagos.

our descendants will be appalled that we let 19,000 children every day die from preventable, poverty-related causes

In a world rapidly growing together, this is bound to change. Of course, there will be a great deal of resistance, as there is already to immigration in many wealthy countries. People do not give up their privileges lightly. And it will have its price: strong welfare systems depend on a sense of moral community that could easily be threatened by more migration.

This is closely related to the point that everyone should have the same rights to healthcare, welfare, etc, not just regardless of where they come from, but also regardless of where they are. In other words, we should be doing everything we can to alleviate suffering everywhere. This poses further challenges: influencing conditions in other countries is not so easy as within one’s own borders. Effective action will require nations to give up more of their sovereignty to supranational unions. This too will face fierce resistance. But eventually our descendants will regard themselves as global citizens – and will be appalled that we let 19,000 children every day die from preventable, poverty-related causes.

4. Healing criminals. At the moment, we lock up extraordinarily large numbers of people. In the US alone, two million humans are in prison, ruining not only their lives, but also making their dependents and communities suffer too. But in 100 years, no one will believe we have an absolutely free will and therefore that anyone chooses to be a criminal. Indeed, there is evidence that we lock up those who are least responsible for their decisions – those with the least capacity for self-control, those who suffer from addictions, or who are mentally ill. In the UK, for example, more than 70 per cent of those in prison have two or more mental-health disorders; in the US, more than three times as many people with serious mental illnesses are in prisons than are in hospitals.

We will not find it easy to decide whom to treat, how radically and when; nor to extend understanding and sympathy to those who have committed the worst of crimes. But our great-grandchildren will be appalled at how we locked up millions of people when we should instead have been helping them.

There are many more changes we could imagine. We have barely touched on the question of inequality, for example. Or perhaps our descendants will be appalled at the idea that the development of life-saving medicines is largely left to private industry. Or that flesh-and-blood humans rather than machines should fight wars, or that liberal democracies should export arms. Or perhaps they will look back on the loneliness of life and death for many in the industrialised world with righteous horror.

For many who live through them, these changes will be extremely uncomfortable. But, of course, they won’t be troubling for those who grow up with them, any more than it is troubling for us to see a black President of the US. What is at first experienced as a concession – spending time recycling rubbish, for example – can quickly seem normal, even necessary. Asking ourselves what we might be condemned for in 100 years is a way of smoothing that transition; of projecting ourselves into the shoes of our great-grandchildren, for whom these new conventions will already be unremarkable.

We can also turn our question around and ask, what will our great-grandchildren admire us for? When we look back, we admire those who courageously challenged the norms of their day, such people as Gandhi or the Suffragettes, Martin Luther King or Nelson Mandela; people who widened the circle of moral concern. We have the chance to do that, too. And if we manage, then perhaps our great-grandchildren will forgive us our sins.
