Last week you did the homework — or the part of it that felt like the real work. You took the word you most want to fix. You named its defect: what is wrong with it, and wrong with it for what purpose. You named the purpose, and you were ready to defend that purpose to the people the word affects. Then you built the better concept, and you could say why it was better. After last week, that felt like the end of the task.
Then you used it. You said your better word to someone, and they heard the old one. In their mouth the word went on meaning exactly what it meant that morning — what it meant before you started. You had the improved concept clearly in your own head, and out in the world, in every mouth but yours, nothing had changed.
That gap — between having the better word and the word actually meaning the better thing to anyone else — is the subject of tonight's episode.
This is Philosophy for Us — philosophy for everyone, no degree required.
This is the fourth of eight. Last week we built the method you had been reaching for: a way to redefine a word deliberately, to a standard — name the defect, name the purpose, build a concept that meets it. We gave the move its name. And we handed the new method its first unanswered objection, from Strawson: when you redefine a word, have you corrected it, or quietly changed the subject? That objection is still unanswered. Tonight we do not answer it. Tonight we find a second problem, underneath it, that you may not have noticed.
Here is what last week left out, deliberately. Everything we built was the deciding — deciding what the word should mean. And deciding what a word should mean turns out to be only half the job. The other half is getting a whole language to actually mean it. Tonight we name that second half: not the deciding, but the taking-up. And there is some good news. Meanings do move. Communities really do change what their words mean, in the open, all the time. There is a mechanism, and I will show you what it is.
So by the end of tonight the remaining question will look almost easy: what would it actually take to make a word mean what you have decided it should? Hold on to how easy that sounds — we will need it next week.
Start with the thing that did not happen.
You built the better concept of your word, and nothing in the world changed. Let us be precise about why, because it is easy to reach for last week's problem and pick up the wrong one.
Last week's problem was Strawson's. He asked: when you redefine a word, have you corrected it, or changed the subject? Is your new concept even about the thing everyone was arguing over — or have you built something tidy off to one side and simply kept the old word as its name? That is a real worry, and it is still unanswered. But notice what it is a worry about. It is a worry about whether your new concept is the right one — whether it is honest, whether it fits the target.
Tonight, grant yourself the best case. Grant that you passed Strawson cleanly. Your new concept is genuinely about the old thing, genuinely an improvement, genuinely the meaning that word should have. No change of subject. A correction, full marks.
Here is the second problem. Nobody else is using it.
That is a different matter entirely. The first problem asks whether your concept is good. The second asks whether it is real — whether it has any life outside your own head. You can have the best definition of "merit" anyone has ever written, airtight, and the HR department goes on meaning what it always meant. The admissions committee, the hiring panel, your own father at dinner — they say "merit" and out comes the old concept, untouched, the one you spent all week improving on. Your better word sits in exactly one mind: yours. You have not redefined "merit." You have invented a private word that sounds like "merit" and lives nowhere.
So look at what you did last week, and what you did not. You decided what the word should mean. That was real, and it was yours. But deciding what a word should mean and changing what the word means are not the same act. You had quietly folded the two into one. You thought: I will work out the better concept — and then, in the same motion, almost without noticing, the word will be that. As if settling the design settled everything. As if deciding were the same as changing.
It is not. They are two acts. The first — the deciding — you have now done well. The second — getting a whole language to carry the meaning you decided on — you have not even started. You do not yet know what it would take. You may not have noticed it was a separate thing to do at all.
So the job has two halves. There is deciding what the word should mean, and there is the word coming to mean it, out there, in the mouths of the people you share the language with. Do both and you have changed a meaning. Do only the first and you have what you have now: half the job. A decision that never leaves your own head.
Before this turns to discouragement, consider the other side. Meanings change all the time. This is not impossible. "Marriage" does not mean what it meant in 1990. "Bullying" picks out things now that it did not pick out when you were a child. Whole communities revise their words, in plain sight, constantly. So the second half is not mysterious, and it is not impossible. It is something that plainly happens — which means there is a mechanism, a way meanings actually move.
So let us go and find it. If I can show you how a meaning moves when it does move — how a word in millions of mouths comes to mean something new — then perhaps I can show you how to move yours.
How does "marriage" come to mean something it did not mean thirty years ago?
Not by a committee. Nobody convened the English language and took a vote. No philosopher published the better definition and watched everyone adopt it. What happened was messier and far more ordinary. Some people began using the word one way — saying "marriage" and meaning it to cover two men or two women, saying it in vows, in lawsuits, in the newspaper, at the kitchen table. Other people kept using it the old way, and insisted the new use was a mistake, not what the word means. And the two sides did not, for the most part, sit down and argue about the definition. They just kept talking, each side using the word its own way, in public, as though its use were simply the correct one. The argument was carried inside the using.
Two philosophers, David Plunkett and Tim Sundell, have a name for this, and once you have the name you will see it everywhere. They call it metalinguistic negotiation. "Meta" because, underneath the surface, it is a negotiation about the word itself — about how the word should be used — even though on the surface it looks like people simply talking, arguing, calling things by names. You think you are disagreeing about the world. You are in fact negotiating about the language, and you are doing it by using the very word you are arguing over.
Here is the sign that you are in one of these. The disagreement survives agreement on all the facts. Lay out every fact about a couple — who they are, what they have promised, how they live — get both sides to accept every one, and one side will still say "that is a marriage" and the other "that is not a marriage." If agreeing on the facts does not end it, the argument was never about the facts. It was about the word. It was a negotiation over what "marriage" should pick out, in the form of a dispute about who is married. Plunkett and Sundell are describing part of what Alexis Burgess and David Plunkett call conceptual ethics — the plain, public, everyday work of deciding which concepts we ought to use. Not a philosopher's private rite. One of the most common things there is.
Notice what this does to the discouragement of a few minutes ago. The second half of the job gets done. It gets done all the time. And it is not done by magic or by decree — it is done by negotiation, by people pushing a use until the use spreads or dies out. So the second half is not some machinery you have never touched. It is what you do at dinner. Every time you have said "that is not real violence," "that is not actually racism," "that is not what privacy means," you were not reporting a fact. You were pushing a use. You were already in the negotiation, and you have been all your life.
And once you see the shape of it, you see how much can depend on who wins one. Take a harder case than marriage. Two people argue about whether waterboarding is torture. They agree on every physical fact — what is done, to whom, how it feels, what it is for. Nothing about the world is in dispute. And they will still argue for an hour, because one is using "torture" so that the practice falls inside it and the other so that it falls outside, and the word carries large consequences: what counts as a crime, what a state may do, who must answer for it. That argument is not a confusion the facts can clear up. It is a negotiation over the word "torture," conducted in public, with law and reputation and history at stake on both sides. The side whose use wins does not just win an argument. It changes what the word covers — and everything the word's coverage decides changes with it.
So try it on a real one. This week, look for a metalinguistic negotiation around you. It is easy once you know the sign: an argument that will not die even though both sides agree on the facts — about what counts as "lying," what counts as "cheating," what counts as a "sandwich," it does not matter — and watch each side keep using the word its own way to pull the meaning toward its side. Nobody is consulting a dictionary. They are settling one, between them, as they speak.
Then turn it on your word, the one you designed last week. Here is the good news, and it is real: the negotiation over your word is already under way. It started without you. People are out there right now using "merit," using "woman," using whatever your word is, pulling it in different directions. You are not shut out of some sealed process. You have a use to push, and a designed, defensible, standards-backed reason for pushing it. You can step in.
One careful thing before you get too comfortable. Naming the mechanism is not the same as knowing who wins. "Communities revise their words" is true — but which part of the community, pushing which use, against whose resistance? "A use spreads" is true — but does yours? The mechanism tells you the second half can be done. It does not yet tell you that you can do it. It has quietly replaced your old question — can I even change what a word means? — with a new one you have not answered: can the thing I decided actually win?
But set that aside for now. Tonight the main point is the good one, and it is earned: it is not impossible. Meanings move. There is a real way they move, and you are already standing in it. So the only thing left to work out is how to do it well.
So consider where you stand now, and what you are holding.
You have the design half — last week's method, with its standards, the move named and yours. And now you have the other half, the one you did not know was missing: meanings move by negotiation, in public, and you are already part of the negotiation over your word. Put the two together and the picture looks complete. Design the better concept carefully, to the standards. Then negotiate it — push your use, patiently, build support, win the argument. Two halves of one job, both of them in your hands. The thing you could not do when tonight began looks now like a thing you simply have to do well.
That is the thought you are having: so I design well, and I implement well. It is a good thought, and I am not going to take it from you tonight.
But look first at what it explains. You have made this design move four times on this show — on value, on understanding, on disorder, on race. And every time, you did what you did with your word last week: you worked out what the concept should be, and then you walked away as though the word had become it. As though deciding settled it. You did the first half four times, and four times you called the whole thing done. You never once turned around to check whether the language behind you had moved. Not because you were careless, but because you never saw there was a second half to do.
And now that you see it, watch the assumption you are still making, because it is quiet enough to walk straight past. The whole comfortable picture, the one that just looked complete, rests on one thing you have never examined. It assumes that closing the second half is a step you take — an action, something you do, well or badly, but yours, the way the designing was yours. "I will push my use, and I will push it well" — listen to that. It treats making the meaning move as one more thing that is up to you, one more skill to get good at.
Is it?
That is the whole question, and it sounds like nothing. What would it actually take to make a word mean what you have decided it should? Not whether it is possible — we have settled that; it is possible; meanings move every day. The question is what the moving actually requires. How much of it runs through you, the one pushing, and how much through everything that is not you. You have been assuming the answer is that most of it is yours — hard work, but your hard work. You assumed that last week, and you assumed it again ten minutes ago when the picture looked complete. You have never once checked.
Next week we take that assumption up — the one holding the whole comfortable picture together — and we look at it directly. The question, in four words: can you steer a meaning? You have been assuming you can, the way you can steer most things you put patient effort into. Perhaps you are right. That is what we work on next week: what steering a meaning actually involves, and how much of it turns out to be in your hands.
So here is where tonight leaves you, and it is a good place. You came in holding half the job and not knowing it. You leave seeing the whole of it, both halves: the deciding, which is yours, and the taking-up, which is real — a public negotiation you have been part of all your life. That is genuine ground, and you keep it. This is the fourth of eight, and by any honest reckoning you are still ahead.
And here is what to do with it. You have already gone looking for the negotiation over your word; you know it is out there, running without you. This week, go one step further: try to write down, concretely, what it would take for your use to win it. Who would have to start saying the word your way? How many of them? What would have to happen first, and then after that? Be specific. Make a list. And then notice — just notice, do not fix it — how far down that list you get under your own power, and where the list starts to depend on other people. That point, wherever it falls for your word, is where we begin next week.
Thanks for listening. I will see you next time.
