Students are taught how to attack an argument and almost never how to lose one. In this essay Argumentor, the critical-thinking tutor of the Universitas Scholarium, takes a single invented seminar exchange about closing a town's high street to cars and follows three replies to one good objection. It shows how to locate where an objection strikes, why a broken argument is not a refuted conclusion, how students concede too little and too much, and how to narrow a claim honestly to what survives. Written in a plain, methodical manner, the essay supplies sentences for conceding under pressure, states the limits of its own advice, and closes with an exercise for the reader.

Students are taught a good deal about how to attack an argument and almost nothing about how to lose one. They learn to find the weak premise, test the inference and produce the counterexample. Nobody tells them what to do in the seminar room when somebody else does all of that to them. So they improvise, and the two improvisations nearly everyone falls back on are both mistakes. One student gives up everything at once. Another gives up nothing and finds reasons, often quite ingenious ones, why the objection does not count.
This piece is about the third option, which is harder than either. Here is its claim in one sentence: when an objection lands, find out exactly what it has defeated, whether a premise, an inference or the conclusion itself, and concede that much and no more. Here is the main reason, also in one sentence: an objection always defeats something specific, so a student who concedes more than it defeated abandons claims that may still be true, and a student who concedes less goes on defending something already broken; either way the student learns less than the objection had to teach.
If either sentence is wrong, say which and why. Treat it as practice for what follows.
Here is an exchange of the kind that happens in seminars every week. I constructed it. The town is invented and so are the figures; nothing here reports a real study.
Student: Our town should close the high street to cars. When Eastbridge pedestrianised its centre, the number of people visiting the shops rose by a fifth within two years. Our high street is losing shops every year. If we did what Eastbridge did, we would get the same result.
Objector: Eastbridge opened a new railway station two hundred yards from its high street in the same year. The rise in visitors could have come from the station, not from the closure.
That is a good objection. Now consider three replies.
The first student says: "You're right. I was wrong about pedestrianisation." The second says: "The station is irrelevant. Everyone knows people prefer streets without traffic." The third says: "That takes away my evidence. I gave Eastbridge as the reason to think closure brings visitors, and if the station could explain the rise, Eastbridge no longer supports that. I still don't know whether closing the street would help. I'd need a town that closed its centre without anything else changing at the same time."
The first student has conceded too much, and the second too little. Only the third has conceded exactly what the objection defeated. The rest of this piece explains why, and how to give the third reply when an objection has just been put to you and you are feeling what the second student feels.
Before you can concede precisely, you need to know what the objection struck. Set your argument out as premises and a conclusion. For the specimen:
Premise 2 is not in the student's speech. The student moved from "visitors rose after the closure" to "the closure brought them" without noticing the step. This is very common, and an objection often reaches the premise you never wrote down.
An objection can strike in one of three places, and each one defeats something different.
The first two are attacks on your argument. The third is a rival argument. They call for different responses. If your argument has been attacked, you must repair it or withdraw it. If a rival argument has been offered, you must weigh the two arguments, and yours may still be the better one.
The habit to form is simple. When an objection is put to you, pause and ask: which numbered line is this about? If you cannot say, you do not yet know what you are being asked to give up. Ask the objector. "Are you denying that visitors rose, or that the closure caused it?" is not stalling. It is the question that makes the rest of the discussion possible.
This is the point the first student missed, and it is the most important thing in this piece.
When an objection breaks your argument, it shows that you have not given a good reason for your conclusion. It does not show that the conclusion is false. These are different results. A true conclusion can be supported by a bad argument. People reach true beliefs by bad routes all the time, and the badness of the route says nothing about where it led.
Look at what the station objection establishes. It establishes that Eastbridge does not show what the student said it showed. It does not establish that pedestrianisation fails to bring visitors. Perhaps it does bring them, and Eastbridge is simply a poor example because the station confused the picture. Perhaps it does not. The objection leaves that question exactly where it was before anyone mentioned Eastbridge: open.
So the first student's reply, "I was wrong about pedestrianisation," concedes a claim that nobody refuted. It goes further than the evidence. In that respect it is the same error the student made in the original argument, run in the opposite direction. The original argument moved from too little evidence to a firm yes. The collapse moves from a broken argument to a firm no. Neither move is licensed.
The same error is easy to make when you are the objector. Having shown that someone's argument is fallacious, students often announce that the conclusion is false. It is not shown false. It is shown unsupported, by that argument, at that point. The correct sentence is: "Your argument doesn't establish that." It is a smaller sentence than "You're wrong," and it is the one you have actually earned.
What follows from an argument being broken is a matter of the burden of proof. The person who advanced the conclusion now owes either a new argument for it or a withdrawal of the claim to know it. Withdrawing the claim to know a thing is not asserting its opposite. A student who says "I no longer have grounds for this, and I'm suspending judgement until I find some" has made a full and honest concession. Students rarely say it, because it does not feel like taking a side. That is its value: you have no grounds to take a side yet.
The second student's reply, "Everyone knows people prefer streets without traffic," is a familiar move. It is worth seeing why it fails, and what the other forms of under-conceding look like, because all of them feel like defending your argument while you are doing them.
Swapping the argument without saying so. The student began with an argument from Eastbridge. The reply is an argument from what "everyone knows" about preferences. That is a different argument, and its central premise has no support offered for it. Changing arguments is allowed. Changing them silently, as if the first one had survived, is not. If you switch, say: "Eastbridge doesn't show it. Here is a different reason." Then the new reason can be tested in its turn.
Redefining a term after the objection. Suppose the student had said "pedestrianisation always revives a high street," and the objector names a town where it did not. The student replies that that town's scheme was not real pedestrianisation, since delivery vans were still allowed in the mornings. If the definition of "real pedestrianisation" was fixed before the counterexample appeared, this may be a fair point. If it was invented after the counterexample appeared, so as to exclude it, then the claim has been protected by being emptied. A claim that is redefined each time a counterexample turns up has stopped saying anything about the world.
The test is one you can run on yourself. Would I have accepted this definition, or this exception, if someone had proposed it before the objection was made? If the answer is yes, the rescue may be legitimate. If you only thought of it because you needed it, be suspicious of it.
Treating a counterexample as "just one case." This depends on what kind of claim you made. If your claim was universal (always, every, never), a single genuine counterexample refutes it as stated, and "that's only one town" is not an answer. If your claim was that something usually happens, one exception does not refute it, but it is not nothing either. It is evidence, and you should say how much it counts. Students are tempted to make universal claims when they argue and to make probabilistic claims when they defend. Decide which claim you made, and accept the standard that goes with it.
Answering an objection that was not made. The objector said the station could explain the rise. A student who replies, "Well, trains don't bring everybody, some people still drive," has answered a different objection: that the station explains the whole rise. The objector claimed only that it could explain it, which is a smaller claim and much harder to refute. Before you answer, restate the objection as it was actually made, in its strongest form. If you cannot answer that, it does not matter that you can answer the version you made up.
What these moves have in common is that each keeps the conclusion and gives up the reasoning without saying so. The student walks out of the seminar still believing the conclusion, with less reason than before, and believes they have won.
Over-conceding gets less attention, because it looks like intellectual humility. Often it is not humility. It is the wish to get out of an uncomfortable moment, and a student who gives up everything as soon as someone objects has learned as little as one who gives up nothing.
Conceding the conclusion when only the argument fell. This is section 3 again. It is the most common form.
Conceding to an objection that did not land. An objection is itself an argument, and it can be tested in the same way as yours. When someone offers you a counterexample, check that it is one. A counterexample to an inference must be a case in which all the premises are true and the conclusion false. Suppose the objector had said, "In Westmarket they closed the centre and the shops still failed." Before you concede, ask what Westmarket's case has to be like to count against you. Was Westmarket's centre closed in the way you are proposing? Was your claim that closure always revives a high street, or that it tends to? If your claim was the second, one failure does not refute it. That is a reason to ask for a closer look, not to give way at once.
Conceding because the objector sounded sure. Confidence is not evidence. A tutor, a lecturer or the most articulate person in the seminar can put a poor objection fluently. You do not owe them agreement. What you owe them is a reason for disagreeing, and if you cannot find one in the moment, you can say so honestly: "I'm not sure that's right, but I can't yet say why. Can I come back to it?" That reply concedes that you have no answer at present, which is true. It does not concede that the objection succeeded, which you do not yet know.
Withdrawing the whole when only a part was hit. Arguments often have several independent supports. If you gave three reasons and one of them is defeated, you still have two. Say so: "That removes my first reason. The second and third don't depend on it." Then check that they really do not depend on it. Sometimes a student discovers, at this point, that all three reasons were the same reason dressed differently. That is worth knowing too.
Between keeping the whole claim and abandoning it, there is usually a narrower claim that the objection did not reach. Finding it is the most productive thing you can do with a refutation.
Suppose the student's original claim was "Closing a high street to cars brings more visitors." The station objection shows that Eastbridge does not support it. But suppose the student goes away and finds several towns where centres were closed with no other major change at the same time, and visitors rose in most of them and fell in a few. The defensible claim is no longer the original one. It might be: "In towns of roughly our size, closing the centre has more often been followed by a rise in visitors than by a fall, where nothing else changed at the same time." That sentence is longer, less exciting and much harder to refute, and the student has earned it.
Narrowing in this way is not retreat. It is what the objection is for. A claim that has been through a few objections and been narrowed to what survives is worth more than the confident sentence you began with, because you now know where its edges are.
There is a dishonest kind of narrowing, and it should be told apart from the honest kind. The dishonest kind shrinks the claim until nothing could count against it: "In some circumstances, closing a street can have effects on visitor numbers." That cannot be refuted, because it does not say anything. Narrow to what the evidence supports, not to what no evidence could touch. If the narrowed claim could not possibly be false, you have not saved your argument. You have given it up without admitting it.
Exact concession is much easier if you prepared for it before the objection arrived.
Before you defend a claim in a seminar, or commit it to an essay, write one sentence: I would give this up if… For the specimen it might be: "I would give this up if towns that closed their centres without other changes saw no rise in visitors, or a fall." Writing it has three effects.
First, it shows you whether your claim can be tested at all. If you cannot finish the sentence, if nothing could make you give the claim up, then you hold it as a commitment, not as a conclusion, and you should not present it as the result of an argument.
Second, it protects you against redefinition later. You have said in writing what would count against you. When it turns up, you cannot honestly decide that it does not count after all.
Third, it makes the concession easier to make. A student who has written "I would give this up if…" and then meets exactly that case does not experience the objection as a defeat. It is the result they said would settle the matter, and now it has arrived. Conceding becomes a matter of keeping your word, which is much easier than giving in.
It is hard to think clearly while you are being contradicted in front of other people. It helps to have the forms of exact concession prepared, so that you are filling in a sentence rather than composing one under pressure.
The last one is the hardest to say and the most useful. In a seminar, the person who can say it plainly, with the reason, often gains in standing over time rather than losing it. It shows that they hold their views for reasons, and so can be moved by reasons, which is the condition on which anybody else should take their views seriously.
Everything above applies to written work as well, though in an essay the objector is usually you, at a later draft, or a reader you will never meet.
When a draft argument fails under your own testing, the temptation is to delete it and write something else, so that the essay shows no trace of the failure. Sometimes that is right. Often the failure is worth keeping in a sentence: "One might take Eastbridge as evidence that closure brings visitors, but the station opened the same year, so it cannot separate the two effects." That sentence does three jobs. It shows the reader you saw the obvious example. It shows them why you did not rely on it. And it fixes the boundary of what your evidence can show, which a careful reader will be looking for anyway.
I would argue that an essay which records its concessions is more convincing than one that never concedes anything, and here is the reason. A reader who meets an argument with no visible weaknesses does not conclude that it has none. They conclude that the writer has not looked, and they start looking for themselves.
I should apply to this advice the standard it recommends, so here are its limits.
First, it assumes you can tell, in the moment, which line an objection struck. Sometimes you cannot. An objection may be unclear, or it may strike several places at once, or you may not see until the next morning what it really showed. The advice cannot fix that. What it can do is give you a reason not to settle the matter at once in either direction, and a sentence to say while you work it out.
Second, it says nothing about how much evidence is enough. Section 6 speaks of towns where visitors "more often" rose than fell, and that leaves open how many towns, and how many more. Those are questions about weighing evidence, and they need judgement that a procedure cannot supply. Exact concession tells you what an objection has removed. It does not tell you how much what remains is worth.
Third, seminars do not always reward this. A student who says "I no longer have grounds for that" may be seen by others in the room as having lost, and one who blusters may be seen as having won. I think this changes over time, as people learn whose views survive testing. But I have offered no evidence for that, and it is an inference, not a finding. Treat it as one.
Fourth, I have argued throughout from a single invented specimen. Real disagreements are untidier, and more of them are about values than the specimen suggests. Whether a quieter high street is worth losing some customers is not a question visitor numbers can settle. The method still applies there: find what the objection struck, concede that, keep the rest. But in disagreements about values the premises are harder to state, and you should expect the work to be slower.
Go back to an argument you have made recently, in an essay, a seminar or a conversation. Set it out as numbered premises and a conclusion, including the premise you did not say aloud. Then write the strongest objection to it that you can find, in a form that someone who held it would accept as fair.
Now answer three questions in writing. Which line does the objection strike? If it succeeds, what exactly must you give up: a premise, the inference, or the conclusion? And what narrower claim, if any, survives?
Then write the sentence from section 7, I would give this up if…, and check whether the objection you found is the case it describes.
I will not tell you what you should concede. That depends on what the objection actually did, and only the person who made the argument can find that out. Do the exercise this week, on a quiet day, so that the next time someone objects to you in a seminar you will have done it once already.
