Consider a meeting. A small foundation — a few people around a table, giving away money that is not their own and trying to do it well. They have funded one programme for years: an after-school centre in their own town, for children who would otherwise be on the street, run by staff who know each of them by name. And tonight there is a figure on the table. The same money, sent overseas — bed nets, clean water, a rural clinic — would, by every honest estimate anyone present can make, save more lives. Not a few more. Many more.
Two people who both want to do good find that they cannot agree.
The first points to the arithmetic. The task is to do the most good possible with what they have, and the most good does not depend on where a person happens to live. Every dollar kept close to home because it is close to home is a dollar that failed to save a life it could have saved. That, on this view, is not generosity but a comfortable form of cowardice. Follow the good.
The second does not reach for a figure at all. She will not, she says, become a person who turns away from the children she can actually see in order to feel clean about a spreadsheet she cannot — and she doubts that an institution run by people who could do that would do much good for very long in any case.
The two do not meet. One is talking about results — the good that can be counted. The other is talking about character — the kind of person an act makes of you. And the point worth marking before we begin is that both of these feel secure. Both sound as though they rest on something firm.
Last week we took the third of these appeals — the one that felt the most secure of all, the flat "you simply may not" — and examined it on its own. We asked what gave it its authority, and could not readily find one. We met Elizabeth Anscombe, who argued that the language of moral duty behaves exactly like law: binding, overriding, indifferent to what you happen to want — and that a law requires a lawgiver, an authority standing behind it, which, when you look for it behind the moral "ought," is not plainly there. Then two serious philosophers, Christine Korsgaard and Philippa Foot, gave their replies. That the authority is real because we give it to ourselves. Or that the standard was never a matter of law at all, but of the plain facts of what a human being is and needs. We left holding both, and the verdict was left open.
This is Philosophy for Us — philosophy for everyone, no degree required. This is the fifth episode of an eight-part series called How to Be Good.
I said, last week, that what came next would be harder — because once you can no longer say what secures the one word you were surest of, the obvious next question is the uncomfortable one: what about the other two? So tonight we put the same question — what gives this word its authority, and what world was it built in? — to results-talk and to character-talk. Then we meet the philosopher who built his best-known book on the claim that all three of them may be broken-off pieces of worlds that have died. And — because this is the one rule of the show, the thing that keeps it honest — we meet, directly opposite him, the serious people who say there is no wreckage here at all: only a living field of inquiry, doing difficult work. By the end you will be holding both. Which one is right is not something anyone has settled — not the people who do this for a living, and not me.
Begin with last week's question, but reduced to something you can carry anywhere — because the whole task tonight is to take what we did to one word and try it on the other two.
Here is the portable form. Anscombe took the language of duty and asked: it speaks like a law, so where is the authority behind it? The general question, the one you can put to any of these moral words, is this. This word is doing heavy work. What world was it built to do that work in — and is that world still here? That is all. One question, carried from word to word: pick up a moral word, find the world it came from, and check whether that world is still in place beneath it.
So take the first of the two we have not yet examined: the appeal to results. The person at the foundation table watching the figures.
Let me put it in full force first, because it deserves that, and because it is probably half of you. Strip away everything else, and what could finally matter, in morality, except how much better or worse off people actually end up? Sentient creatures, suffering or flourishing — that is as real as anything gets. So the right act is simply the one that does the most good and the least harm, and a rule that forbids the best available outcome has mistaken a means for the end it was meant to serve. The person pointing at the bed nets is not being cold. She is being honest in a way most of us flinch from: refusing to let the warm feeling of helping the children she can see outweigh the lives she cannot. There is something clear and bracing in that, and anyone who has felt it knows it does not feel like a fragment of anything. It feels like clarity.
Now ask the question of it. The whole approach — every version of it, from Jeremy Bentham in the eighteenth century to the person at the table — turns on one phrase. The good. Do the most good. Maximise the good. And it is a genuinely powerful method: it weighs, it adds up, it corrects for bias, it can tell you that you are wrong. But a calculation needs some quantity to work on. So ask the plain question — Anscombe's question, turned on this word instead of the last. The good — what is it? What are we adding up?
And the answers grow scarce the moment you actually ask. The good — is it happiness? Whose, measured how, over how long? Is it satisfied preferences — including the cruel ones, including the ones a person would be ashamed of? Is it a list of the things that make a human life go well — and if so, who drew up the list, and why that one rather than another? The machinery of the calculation is exact to the decimal point. What it is calculating toward is a blank that has to be filled in before the calculation can run — and the moment you go to fill it, you begin to wonder whether the agreement everyone seemed to share was ever really there.
Here is one forceful account of why — and I will flag it as an account, a reading, because we will set a name and a serious opponent against it before the hour is out, and you should not take it from me as plain history. On this reading, there was a time when "the good" was not a blank. In the older picture — Aristotle's, and the long tradition after him — every living thing had an end, a point, a flourishing proper to its kind, the way an acorn is for becoming an oak. And a human being had one too: a definite shape of a life lived well, something one could be right or wrong about, built into what we are. In that world, "do the most good" had a destination already marked on it. The good had content — content people could argue toward, because they shared a picture of where the argument was headed.
And then — this is the part the account says does the damage — the modern world gave up the idea of an end. The shared purpose, the built-in point, the notion that there is a single human flourishing we are all aimed at: serious people stopped believing it, for reasons that were often good ones. And consider what that does to the calculation. You keep the method — maximise the good — and you lose the quantity you were summing toward. So "the good," on this reading, becomes a placeholder, and each of us fills it, without quite noticing, with whatever we already wanted. Which would explain something. It would explain how two people can each say, in complete sincerity, "I am only following the good," and reach opposite conclusions and hold to them. They would be running the same method on different private values, and the method could not tell them apart.
Now do it yourself — not on the person at the table, on you. Find the last time you settled something by saying "it is the right thing because it does the most good," or "more people are helped this way," or "you have to look at the bigger picture." You have said a version of it. Now examine the word. The good — in that case, your own — what were you actually adding up? Whose flourishing, counted how, toward what end?
And here I have to do what I did last week, because otherwise I would be cheating you. Asking the question is not the same as answering it. When you examine your own "good," it may fall apart into a blank you had been filling with your own taste all along. But — and give this equal weight — it may not. It may hold. There may be a real, defensible answer sitting right there, content you could put in front of anyone; and a serious philosopher would look at the same thinness you felt and tell you that you have found nothing alarming at all — that what fills "the good" is a live, working question in a healthy field, argued every day, with real progress, between preference-satisfaction and welfare and objective lists of goods. On that reading you did not find wreckage; you found an open question in a working field. Which it is remains genuinely open — no one yet knows, and neither, yet, do I. So hold whatever you found loosely. There is one more word to examine first.
Now the last of the three: the appeal to character — the other person at the table, the one who would not reach for a figure.
Put it, again, as strongly as it can be put, because it may be the half of you the first one was not. The deepest moral question, this voice says, was never "what is the right act?" Acts are only the surface. The real question is "what kind of person should I become?" A good life is not a list of correct decisions; it is the steady exercise of the virtues — honesty, courage, justice, mercy — and the person who genuinely has them does not consult a rulebook. They see what the situation requires, the way a good doctor reads a patient or a good friend reads a silence, in a way no rule could fully set out. So the woman who will not turn away from the children she can see is not being soft. She is protecting the one thing she cannot recover if she trades it away: what she is becoming. And anyone who has ever refused a clean deal because something in them said not like this, not me knows that this does not feel like a fragment either. It feels like the most solid thing about you.
So ask the same question of it. And it runs on a word we have already met tonight, in a different form. Good. A good person. An excellent human being. We took "the good" as a quantity to add up; here it is "good" as a quality to embody. And the difficulty is the same difficulty. "Good" for a thing with a clear function is easy — a good knife cuts, a good racehorse runs, and no one argues, because we know what the thing is for. But a good human being — good at what? Excellent toward what end? Courage is real, but a virtue is an excellence measured against a standard, and the standard has to come from somewhere — somewhere outside your own preferences, or it is not a standard but a flattering description of how you already are.
And here is the same kind of account of where this one came from — the same caveat, a reading, with an opponent to come. On this telling it is the most concrete of the three, which is why it is the hardest to shake. Aristotle's virtues, the account goes, were never free-floating. They were the excellences of a citizen — of a particular kind of person in a particular kind of community, the polis: a city with a shared, public account of what a human life is for, with roles, practices, elders, a whole tradition that supplied both the content of the virtues and the judges who could tell the genuine article from the counterfeit. In that world, "be a good man" was not vague. It was as definite as "be a good citizen of this city," because the city told you what good meant, trained you into it, and corrected you when you got it wrong.
Now lift "be a good person, be virtuous" out of that — out of the shared end and the community that held it — which, on this account, is just what the modern world did. What you are left holding is a recommendation with the content drained out. Whose virtues? Ranked how? Aimed at what? Because without the shared picture, one person's courage is another's recklessness; one person's loyalty is another's corruption; one person's humility is another's cowardice. "I am going to be the kind of person who…" can be completed almost any way at all, and on this reading there is no city left to tell you that you completed it wrongly. Which would again explain the table: how the woman guarding her character and the man following the numbers can both be people of real conviction, each as good as either can tell, and still have nothing to put between them that would settle the matter. On this account they are each being excellent toward an end the other does not share, and the shared world that could have judged between the ends is precisely what is gone.
The same exercise, on yours, not on hers. The last time you drew a line by saying "I am simply not going to be the kind of person who does that." Examine it. The kind of person — measured against what? Perhaps you find a substantial standard you genuinely share with people you respect, people who could tell you when you have deceived yourself — a standard with real content, right there, no lost city required. Or perhaps you find something thinner, closer to your own taste with a fine word laid over it. I do not know which, and finding the thin one would not prove that the thin one is all there is.
Because there are serious people — you met one of them last week — who say the whole "lost city" picture is the wrong way to think about "a good person" in the first place. Foot's answer was that you can read the standard directly off the facts of what a human creature is and needs — that we assess a person the way we assess any living thing, against the form of its kind, with no polis and no lawgiver required; the standard never went anywhere, because it was never a city's to hold. And others say you can build it out of reason itself. So if you could not readily say what your character-word was measured against just now, that may be a collapsed world — or it may be that you were looking for the wrong kind of foundation, and the real standard is exactly where it always was. Hold it loosely, like the other one. Because now all three pieces are on the table — the duty-word from last week and these two tonight — and it is time to meet the philosopher who looks at all three at once and tells you what he thinks you are really holding.
Step back and look at the table. Three moral words now, each with the same difficulty beneath it — each a word that speaks with complete confidence and yet, when you ask what world it was built in, cannot readily produce that world. The duty-word: a law with no authority you can find. The results-word: a calculation with no agreed quantity. The character-word: an excellence with no city to set the standard. Three fragments. And there is a philosopher who built his best-known book on the claim that "fragments" is the right word — and who gives the whole picture a force that nothing we have said so far has had.
His name is Alasdair MacIntyre, and the book is After Virtue, published in 1981 — one of the most important works of moral philosophy of the last century.
He opens it with a thought experiment. Imagine a catastrophe overtakes the natural sciences. A wave of public anger; books burned, laboratories destroyed, scientists killed, the whole enterprise wiped out. Then, generations later, people pick through what remains and find the surviving pieces: half a page of a journal, an instrument no one can use, the word neutrino, the word mass, fragments of theorems. And they begin using the words again. They hold debates. On the surface it sounds exactly like science. But the theories that made the words mean something are gone — burned, forgotten — so the words no longer connect to anything that could settle their use. The arguments cannot end, because there is nothing left beneath them to end against. It looks like science. It is the appearance of science with the substance gone.
And then MacIntyre makes the claim that gives the book its force. That, he argues, is the actual condition of our moral language. Not the sciences' — ours. We are the people picking through what remains. We inherited the words — duty, the good, virtue, justice, rights — but not the whole traditions, the vanished worlds, that gave the words their sense. We use them at full volume, in complete earnest, and they no longer reach the ground that would let us settle what they mean. So of course the arguments do not end. On this reading, that is not a fault in the people arguing. It is the nature of the situation they are in.
And this reaches back to the one fact we fixed in the very first hour of the series — the thing that does not move, the argument that will not end, two reasonable people at a kitchen table no closer at midnight than they were after dinner. We have spent five weeks circling the question of why. Here, for the first time, is an answer with real weight. On MacIntyre's diagnosis, the deadlock is not stupidity, and not bad faith, and not a missing fact. It is that the two people are reasoning correctly — from premises drawn from incompatible, collapsed worlds, with no shared world left in which the premises could be tested. The deadlock is not a failure of the people. It is a defect in the shared language they have both inherited. That is a harder and more troubling claim than anything we have had, and you can feel why it is hard to set aside once you have heard it.
And he gives the defect a history — this is the genealogy I promised back in week one, when I said the reasons you trade come from somewhere. Here is where I pay it. How did the worlds die? MacIntyre's account picks up exactly where Anscombe's left off. The Enlightenment — the great project of modern thought — set out to do something no one had quite attempted before. It tried to justify morality from the ground up, using reason alone, or human nature, or sentiment, or a social contract — and, crucially, without a shared end, without a divine lawgiver, without a tradition to stand inside. Kant looking for it in pure reason; Hume in the sentiments; the contract theorists in agreement — and I am compressing centuries into a sentence, which is part of why this is a reading and not a proof. First-rate minds, every one, all searching for a foundation that would hold for everyone. And on MacIntyre's telling the project failed — not for any lack of genius, but because the morality they were trying to ground had only ever made sense inside the framework of ends and traditions they had just discarded. You cannot keep the conclusions of a world whose premises you have abandoned. What was left, when the dust settled, was the material we have been handling all hour: the words, still in everyone's mouth, with the worlds that gave them sense gone from beneath them.
Now I have to stop and be plainer with you than on any night so far, because this is the point where I am most tempted to cheat you — to let a powerful idea pass as a proven one. I have just given you the most powerful version of this idea I can, and I am not going to pretend, even for a moment, that it has been proven. It has not. It is a diagnosis. It is, I think, the deepest one anyone has offered — it explains more of what you actually feel at that table than anything else you are likely to hear. But it is one philosopher's reading of the long history of Western morality, and a reading of history, however powerful, is not a proof. MacIntyre says the Enlightenment project failed and left fragments behind. There are serious people — first-rate ones, working now — who say it did no such thing: that it never failed, or never needed to do the impossible thing he says it attempted, or that the so-called wreckage is nothing of the kind. And if I let you leave here believing the diagnosis won tonight, I will have sold you a conversion and called it philosophy. So I will not. Instead I will do the harder thing and give those people the floor, at full strength, now.
So. The diagnosis says: three fragments of dead worlds, no neutral ground on which to judge between them, a deadlock with no bottom. Here are the people who look at the very same table and say: you are looking at a living field of inquiry, and you have mistaken its difficulty for ruin.
Start with the plainest version, because it is almost blunt. Walk into any serious philosophy department today and you will find people doing, at a high level, the exact thing MacIntyre says became impossible after the collapse. They argue about consequences and duties and virtues; they build theories, test them, change one another's minds. And their reply to the fragmentation story is simple: you have mistaken a hard, healthy disagreement for a collapse. These three families are not fragments. They are live, rival theories — and, like rival theories in any field, they correct one another. The consequentialist reminds the duty-theorist that results genuinely matter; the duty-theorist reminds the consequentialist that there are lines you do not cross; the virtue-theorist reminds them both that rules are not the whole of a life. That is not the sound of a language that has lost its world. It is the sound of a field at work.
And they have an account of how that work gets done — it is not a free-for-all. The method has a name: reflective equilibrium, from John Rawls, in A Theory of Justice, 1971. It runs like this. You take your firmest considered judgements — the ones you would stake everything on: that slavery is wrong, that torturing a child for amusement is wrong — and you take your candidate principles, the general rules you are drawn to, and you move back and forth between them. When a principle endorses something monstrous, you discard the principle. When a strong intuition cannot survive any principle you would accept, you give up the intuition. Back and forth, adjusting each against the other, until the whole set is consistent. That is not the conduct of people lost among ruins. It is, the Rawlsian says, close to how disciplined inquiry actually makes progress — including the natural science MacIntyre used as his image of the real thing. Physics has open questions at its frontier too. We do not call physics a ghost. We call the open questions the frontier of a living science — and that, they say, is precisely what the disagreements in moral philosophy are.
Now the deeper version, because it goes straight at the central claim. The whole diagnosis rests on one point: that there is no neutral standpoint — no court standing above the traditions, at which someone inside one collapsed world and someone inside another could meet and actually settle their difference. Remove that point and the diagnosis fails. And there is a serious philosopher whose entire project is, in effect, to build that court: T.M. Scanlon, in What We Owe to Each Other, 1998. His idea is that an act is wrong if it would be forbidden by any principle that no one could reasonably reject as a basis for general, willing agreement among people trying to live together. This is not "what does my tradition say." It is not a fragment of anything. It is a procedure — one any two people can run together, here, now, across whatever worlds they came from: not "whose inheritance wins" but "what could neither of us reasonably reject." And people do run it, in real arguments, and it moves them — you have changed your own mind on realising that you were demanding something the other person could fairly refuse. If that procedure is real, then the two at the foundation table are not stranded across incompatible worlds at all. They share more than they know, and the deadlock is not bottomless — it is only hard, unfinished work they have not yet carried far enough.
Now look carefully at what these two replies do, because I am not raising them in order to set them aside for you. They cannot honestly be set aside. If the live-theories people are right, then every trace of "collapse" you felt earlier tonight — the thinness of "the good," the homelessness of "virtue" — was never collapse at all. It was simply what an open, working field looks like from the inside, in the middle of the argument. And if Scanlon is right, then MacIntyre's central claim — that there is no neutral standpoint — is not merely doubtful but false, and the whole diagnosis loses its foundation. These are not weak objections dressed up to look impressive. They are exactly as serious as the diagnosis, held by people as careful as MacIntyre, and the argument between them is live, right now, unsettled, in the journals — not a historical curiosity but a present dispute with no winner yet. You will not leave tonight having watched the diagnosis win. Nor having watched it lose. Both remain in force. That is not evasion. It is the honest state of the question.
So where have we arrived, honestly? Last week we could not say what gave one of these words its authority. Tonight we put the same question to the other two, and asked whether they would fare any better — and here is what we found, no more and no less.
We did not establish that these three theories are wreckage. And I mean that plainly, because it is the thing you will be most tempted to leave believing. I gave you the most powerful case anyone can make that they are — three words, three dead worlds, a brilliant modern project that overreached and left fragments behind — and that case is real, and it is a genuinely searching account of your kitchen-table deadlock. You cannot wave it away. If you leave here pretending you never heard it, you are hiding from something true. But a case is not a proof. And standing right beside it, just as serious, just as carefully built, is the reply that there is no wreckage at all — that you have been watching a living field do hard, ordinary work and mistaking the difficulty for a ruin, and that we may share a procedure, here and now, for settling these matters that no dead tradition could reach. Both of those remain. Neither refuted the other tonight, and neither was ever going to — the people who actually hold these views have not managed it either. The argument is live, and it is not yours or mine to close.
And hear what we did not do, so that you can hold me to exactly what I showed and no more. I have not told you whether the diagnosis is right. I have not sent you off to recover a tradition, and I have not told you to trust the procedure, and I have not told you to discard any of it. One philosopher's reading of history, at its strongest, against the best of the people who reject it — and the verdict left open, because that is where the verdict actually is.
There is one easy version to refuse first, and tonight makes it more tempting than ever. Do not reach for the one that says: well, if it may all be fragments, then perhaps none of it is real, it is all just opinion, so you can relax. You do not believe that, and you can check it yourself, right now. Try, honestly, to hear "cruelty for its own sake is wrong" as nothing more than a flavour you happen to dislike. The sentence will not sit still for it — it keeps pointing at the act, not at your palate. So that reply is not available to you, not even tonight, not even with everything we have called into question. Whatever the diagnosis turns out to be, it was never a permission slip.
But there is one more thing I have deliberately not touched, and it is worth naming plainly before we close, because it is where we go next. If all three of these may be fragments — or may be live rivals — and no one can yet tell you which, then what does that do to the thing you have quietly been doing your whole life? The sensible, decent thing. Keeping an open mind. Seeing the merit in each. Declining to commit, because committing looks like the choice of someone who has not grasped how hard the question is. We have spent five weeks examining the theories. Next week the examination turns around, and it turns on you — on that open-mindedness you walked in here rather proud of. And it asks a question I am not going to answer tonight, and you should not let me answer early: is that open-mindedness the maturity you have always taken it for — or is it something else entirely, something that merely resembles maturity? I will not answer it tonight, and you should not let me. But the question is now in the room, and it was not there this morning.
Thanks for listening. I'll see you next time.
