G: [Non-text content: thoughts; content_type=thoughts]

G: I’ll filter this the way you’re asking: not “what doctrine says,” but what arguments still have footing after you demand explicit textual/legal anchoring and refuse undefined category creep.

G: [Non-text content: thoughts; content_type=thoughts]

G: [Non-text content: reasoning_recap; content_type=reasoning_recap]

G: No argument for complete immunity survives your filter.

The strongest surviving argument is narrow: Congress cannot criminalize acts that the Constitution gives exclusively to the President, because those powers are “conclusive and preclusive.” The Court’s clearest examples are things like pardon/veto powers, and in the case itself, Trump’s DOJ discussions/removal threats were treated as within executive prosecutorial/removal authority. citeturn132767view0turn175071view0

The weaker-but-still-existing argument is presumptive immunity for official acts, but this is exactly where your objection bites hardest: “official act” is broad, underdefined, and doctrine-heavy. The Court says prosecution can proceed only if the government shows no danger of intrusion on executive functions, but that test is not textually enumerated. citeturn175071view3

Arguments that do not survive your filter well:

1. “Official act = immune”
   Too broad. The opinion itself says unofficial acts get no immunity and not everything a President does is official. citeturn175071view2

2. “Impeachment conviction is required first”
   The Court rejected that: making impeachment a required step before criminal prosecution has little support in constitutional text or structure. citeturn175071view2

3. “History proves total immunity”
   Weak. Prior precedent repeatedly subjected Presidents to criminal process, including Burr, Nixon, and Vance. citeturn132767view4

4. “Civil immunity implies criminal immunity”
   Weak. Fitzgerald was civil damages immunity, and even Constitution Annotated frames it as policy/functional reasoning, not explicit constitutional text. citeturn132767view4

So your cleanest formulation is:

The only immunity that survives strict legal parsing is immunity for specifically identifiable exclusive Article II powers. Anything beyond that depends on an undefined “official acts” category plus functional doctrine, not explicit constitutional allocation.

G: I think I finally understand the precise place where you're aiming your criticism, and it's actually narrower than "the Court got it wrong."

Your criticism is about legal determinacy.

You're essentially saying:

"A court cannot create a legal category that carries legal consequences while simultaneously declining to specify what belongs in that category."

That's not merely a political complaint. It's a jurisprudential complaint.

After looking through commentary from both supporters and critics of the decision, I found surprisingly little that directly answers that objection. Instead, almost everyone changes the subject.

The strongest counterargument I found isn't textual—it's structural.

It goes roughly like this:

"The Constitution doesn't enumerate every consequence of separation of powers. Courts have always had to develop implementing doctrines. 'Official acts' is intentionally left open because it would be impossible to exhaustively define every future exercise of executive authority. The common law develops standards incrementally through later cases."

That's probably the best version of the other side. citeturn0search0turn0search11

The problem, from your perspective, is obvious.

You don't object to courts interpreting words.

You object to courts creating an undefined legal container whose contents determine criminal liability.

Those are different things.

For example:

• "Speech" requires interpretation.
• "Search" requires interpretation.
• "Commerce" requires interpretation.

But those are constitutional terms.

Here, the Court effectively says

There exists a category called "official acts."

and then says

whether prosecution is allowed depends on whether conduct falls inside it.

without actually defining what makes something an official act beyond broad functional language. The Court expressly leaves much of that work to future litigation. citeturn0search0turn0search17

That's a different type of legal move.

I actually think your analogy can be made even tighter.

Instead of the bedroom example, I'd put it like this:

Imagine Congress passed a law saying:

"Anyone who enters a Restricted Area commits a felony."

Then, when asked where the Restricted Area is, Congress replies,

"We'll decide that one lawsuit at a time."

Most lawyers would immediately recognize the due-process problem.

The legal consequence exists before the boundary does.

Your complaint is that immunity is being treated the same way.

I did try to find someone making exactly your objection.

Interestingly, I found people criticizing the opinion for being vague, but usually from practical or democratic perspectives.

One criticism that comes closest comes from scholars arguing that the Court transformed prior executive-immunity balancing into a much stronger protection while leaving lower courts to determine what qualifies as an official act. They argue this creates uncertainty precisely because the operative category lacks clear boundaries. citeturn0search8turn0search9

The one place I think someone could genuinely challenge your position is this:

They could argue that the law frequently works through standards rather than rules.

Examples include:

• "reasonable suspicion"
• "probable cause"
• "undue burden"
• "materiality"
• "good faith"

None of these have bright-line definitions.

If that's true, then perhaps "official acts" is simply another legal standard.

I don't think that's a frivolous argument.

However, I also think you'd respond with a distinction that is worth taking seriously:

Those standards generally regulate how existing legal powers are applied. They don't ordinarily create a brand-new category that determines whether criminal law applies at all.

That's a qualitatively different role.

Whether that distinction ultimately persuades someone is another matter, but it does identify the specific fault line. It's no longer "vague law is bad"; it's "when a legal category determines the existence or absence of criminal liability, the legal system owes a more determinate account of what that category includes than merely saying courts will work it out later."

I have to say, after searching specifically for arguments that avoid appeals to history, tradition, or institutional practice, I did not find a substantially stronger textual or logical rebuttal than the structural one above. Almost every serious defense eventually rests on the premise that separation-of-powers doctrine necessarily requires judicially developed standards rather than exhaustively defined categories. Whether that's a sufficient justification is exactly the point on which the debate turns.

G: I think I finally see the distinction you're insisting on, and I think it's a useful one. I was still treating your objection as one about constitutional interpretation, when you're actually making a prior objection about the logic of classification itself.

To restate it as cleanly as I can:

Before a rule can operate on a category, the category must have membership conditions.

That's not a legal proposition. It's a proposition about language, logic, and formal systems.

In mathematics, we don't say "Let (S) be the set of special numbers" and then proceed to prove theorems about (S) without ever giving either:

• an enumeration,
• a generating rule, or
• a membership test.

One of those has to exist, or "belongs to (S)" has no determinate meaning.

Likewise, in computer science you don't write

if OfficialAct(x):
    immune = True

without ever defining OfficialAct().

It isn't merely incomplete code.

It's an undefined function.

Everything downstream depends on something that has never been specified.

I also think you've hit on why comparisons to things like "reasonable suspicion" don't satisfy you.

Those are standards, but they aren't primitive symbols.

They're embedded in decades of doctrine, statutory context, evidentiary principles, jury instructions, appellate review, and countless concrete applications. You may think they're imperfect, but they have a semantic neighborhood.

Your objection is that "official acts"—at least as used in the immunity opinion—was assigned enormous legal consequences without first supplying comparable membership criteria.

Whether one agrees with that characterization is another question, but the structure of your criticism is different from simply saying "it's vague."

There's actually a concept from logic that comes close to what you're mean.

A distinction exists between:

• intension — the rule for belonging to a category.
• extension — the actual members of the category.

For a meaningful category, you normally need one or the other.

Either

These are the members.

or

Here is the rule that determines membership.

Your complaint is essentially

They provided neither a sufficiently specified intension nor a sufficiently specified extension, yet attached legal consequences to membership.

That is a cleaner way of putting it than "it's vague."

Another way to phrase it comes from formal language theory.

A predicate must be well-defined.

If I define

(P(x)) = "x is an official act"

then I should be able, at least in principle, to evaluate (P(x)) for arbitrary x.

If no evaluation procedure exists—not necessarily an algorithm, but at least criteria—then (P) is underdefined.

Again, reasonable people can disagree about whether the Court gave enough criteria, but that's the form of the objection.

One point where I'd slightly separate from your formulation is this:

"You cannot define a set that has no definition."

In mathematics, you actually can introduce an undefined primitive. Geometry does this with "point" and "line." Set theory itself leaves "membership" ((\in)) primitive.

The important caveat is that those primitives are constrained by axioms.

You don't define "point," but you immediately tell me what points can and cannot do.

Likewise, if someone introduced a primitive legal category, the criticism wouldn't simply be that it wasn't exhaustively defined; it would be that too few constraints were supplied to determine its behavior. That's a slightly stronger and more precise criticism.

So I might express your position this way:

"The problem is not that the Court failed to enumerate every official act. The problem is that it created a predicate whose truth conditions are insufficiently specified for the legal consequences attached to it. Without sufficiently defined membership criteria or governing constraints, the category cannot perform the logical work the opinion requires of it."

I think that's the most rigorous version of what you've been circling around.

It's no longer a complaint about constitutional policy or even legal methodology.

It's a claim about the minimum requirements for a category to carry inferential weight in any rule-based system, whether that system is mathematics, programming, formal logic, or law.

That's a much more general claim, and because it's more general, it also becomes easier to evaluate independently of anyone's views about presidential immunity.

G: I think you've sharpened the idea again, and I also checked the opinion's terminology.

The Court actually uses several overlapping phrases:

• "core constitutional powers"
• "exclusive sphere of constitutional authority"
• "conclusive and preclusive constitutional authority"
• "official acts" (which receive at least presumptive immunity rather than absolute immunity) citeturn0search0turn0search2

Notice something interesting.

Those are descriptions, not tests.

That's a distinction people often blur.

Suppose I say:

"Prime numbers are the fundamental numbers."

That's a description.

The membership test is:

divisible only by 1 and itself.

Without that second sentence, "fundamental" is rhetorical rather than operational.

That's essentially what you're objecting to.

The Court's language sounds increasingly precise—

• core
• exclusive
• conclusive
• preclusive

—but none of those adjectives, by themselves, tell a lower court how to decide whether a new case belongs inside or outside the category.

They don't function as an algorithm, a rule, or even a reasonably bounded heuristic.

I also think you've arrived at a distinction that is more generally useful than this particular case.

There are really three levels.

1. Enumeration

   Here are the members.

2. Generating rule

   Here is how you determine whether something belongs.

3. Descriptive label

   Here is a name that sounds like it identifies the members.

The third one is not a substitute for the first two.

Calling something "core constitutional authority" doesn't itself identify its extension.

It's analogous to saying "important books" without saying what makes one important.

The other thing I liked from what you just said is this:

"Standards come from generating rules."

I would modify it slightly.

I'd say:

A useful standard is a compressed representation of an underlying body of membership criteria.

That body of criteria may be:

• precedent,
• statutory language,
• constitutional text,
• accumulated examples,
• or some combination.

The standard works because you can decompress it when the hard cases appear.

That's why "reasonable suspicion" doesn't completely float free.

When the standard becomes uncertain, courts don't shrug and say "reasonable means reasonable."

They unpack it using hundreds of cases discussing what counts and what doesn't.

The standard is shorthand for a much richer structure.

I think your strongest observation is this:

If a standard cannot be expanded back into the rules that justify it, then it isn't functioning as a standard—it is functioning as a label.

That's a fairly deep point.

One place I'd still push back just a little is your statement that you "need five instances" before you can infer the shape of a category.

Not necessarily.

Sometimes one explicit generating rule is enough.

For example:

even integers

has infinitely many members from a single rule.

So I don't think the problem is the number of examples.

I think it's the absence of either:

• a sufficiently explicit generating rule, or
• enough positive and negative examples to infer one.

That's actually a stronger criticism because it doesn't depend on an arbitrary number.

There's another concept that I think you'll like because it matches what you've been reaching for.

In philosophy of language and logic, people distinguish between criteria of application and paradigm cases.

A concept can be taught by:

• explicit criteria ("a bachelor is an unmarried adult man"), or
• enough accepted examples and counterexamples that the criteria become apparent.

Your complaint is that the Court supplied neither in sufficient detail.

It gave neither a complete criterion of application nor a robust collection of paradigm cases from which one could reliably infer the criterion.

That's a more precise way to state it than saying the category is "vague."

It's a claim that the category lacks an adequately specified criterion of application.

I also think this dovetails with something you've said in earlier conversations about standards versus rules. You weren't rejecting standards. You were treating them as a kind of compression algorithm: they save time because they summarize an underlying structure. When the compressed form fails on an edge case, you "decompress" back to the underlying rules and adjust the standard if necessary. A standard that cannot, even in principle, be unpacked into underlying criteria isn't really functioning as a standard—it's functioning as an assertion that "trust us." Whether one ultimately agrees with your conclusion about this particular opinion or not, that's a coherent distinction, and it's one that exists at the level of logic and language before you ever reach constitutional law.

G: I think we've narrowed the disagreement to something much cleaner than where we started.

Your claim is not:

"The Court reached the wrong conclusion."

It's closer to:

"The Court introduced a predicate into the legal system without supplying sufficient criteria for determining the predicate's truth value."

That's a logic problem before it's a constitutional one.

One thing I would tighten even further is the distinction between descriptive and operative language.

An operative definition has to let another reasoner apply it independently.

For example:

• "Prime number" is operative because two mathematicians can independently test a candidate.
• "Reasonable suspicion" is imperfect, but courts have built up enough criteria and examples that another judge can at least explain why a case fits or doesn't fit.
• "Core constitutional powers," standing by itself, is much more descriptive. It tells you these powers are important, not how to identify them in novel cases.

That doesn't necessarily make it legally invalid, but it does mean the phrase itself is not doing the logical work. The work has to come from somewhere else.

I also think you've put your finger on something that appears in computer science under a different name.

A predicate shouldn't require an oracle.

If the only way to know whether

OfficialAct(x)

is true is

ask the Supreme Court,

then you've defined an oracle, not a criterion.

In theoretical computer science, an oracle can answer questions that the rest of the system cannot decide. That's perfectly acceptable as an abstract mathematical model, but it's not usually what we mean by a usable definition. A useful predicate should have some independently understandable criterion of application.

That seems much closer to your concern than simply saying "it's vague."

I also liked your reformulation of standards.

I'd put it this way:

Rules generate standards; standards do not generate rules.

A standard is a compression of accumulated reasoning.

When the compression fails on an edge case, you expand back to the underlying rules.

If no expansion is possible—if there's nothing underneath—then what you have isn't really a standard. It's just a label.

That, to me, is the strongest and most general version of your point because it applies far beyond this case. It applies to scientific classification, programming, taxonomy, and legal reasoning alike.

One place where I'd still separate description from criticism is your hypothetical about selling Kentucky. I agree it's useful as a stress test, but it doesn't by itself show the category is incoherent. A defender of the opinion would likely say, "Making treaties or recognizing foreign governments are official functions; attempting to alienate a state is beyond constitutional authority." Whether that answer is persuasive depends on the additional criteria they invoke. Your deeper objection isn't that they couldn't answer that hypothetical; it's that the opinion itself doesn't provide a sufficiently general method for answering comparable hypotheticals without later judicial elaboration.

Stepping back, I think the idea you've been developing could be summarized in a single principle:

Any category that determines legal consequences should have publicly usable criteria of application. Those criteria may consist of an explicit enumeration, a generating rule, or a sufficiently developed body of precedent from which a membership test can be inferred. A descriptive label alone is not enough, because it cannot be applied independently by future reasoners.

That's a claim about the structure of reasoning itself. Someone can disagree with it, but if they do, they need to explain why a category that carries legal consequences does not require independently usable criteria. That shifts the debate from "Is this President immune?" to the more foundational question, "What makes a legal category operational rather than merely descriptive?" I think that's the level at which your argument is strongest.

G: I actually think your strongest version isn't about Trump at all. It's about how definitions work. The more you make it about one case, the easier it is for people to dismiss it as politics.

Here's how I'd say it in about a minute:

:::writing{variant="standard" id="48172"} Imagine Congress passed a law saying, "Cars are exempt from this rule."

The first question everyone would ask is, "What counts as a car?"

You don't have to list every make and model, but you need some way to tell. A definition. A test. A rule. Something that lets different people reach roughly the same answer.

Now imagine the government responds, "We'll decide what's a car whenever a case comes up."

That's not really a definition. It's just a promise that someone else will decide later.

That's my problem with the Supreme Court's immunity ruling. My objection isn't whether presidents should have some immunity. My objection is that the Court created a category with major legal consequences without giving a usable membership test for what belongs in that category.

A legal standard should be a shortcut built from underlying rules. When the shortcut breaks down, you go back to those rules. But if there are no underlying rules—only a label—then people aren't applying law anymore. They're waiting for someone else to tell them what the category means after the fact.

Whatever you think about this particular President, that's a dangerous way to define any legal power. :::

The only thing I'd change for an audience of lawyers or mathematically minded people is one sentence. I'd introduce the phrase that I think you've been searching for all afternoon:

"A legal category that determines rights or liabilities needs publicly usable criteria of application."

Or, even shorter:

"If a category has legal consequences, it needs a membership test."

I think that's the sentence you've been trying to discover. It doesn't mention presidents, immunity, conservatives, liberals, or even the Constitution. It states a general principle. Then, once people accept that principle, you ask whether the opinion supplies such a test. That keeps the discussion focused on reasoning rather than immediately splitting along political lines.

One other thing I'd recommend: avoid saying "there's no definition whatsoever." A supporter of the opinion can point to phrases like "core constitutional powers" or "exclusive constitutional authority" and say, "See? There is a definition."

Instead, make the more precise claim:

"Those are descriptions, not criteria of application."

That's a much harder point to sidestep because it concedes the words exist while asking the more important question: How do I apply them independently to a new case? That's the question your argument is really about.

G: I think for an ad, the key is that every sentence has to move the listener one step forward. No hedging, no "my position is," no legal jargon unless it's immediately explained.

I'd write it like this:

:::writing{variant="standard" id="67281"} Every law depends on definitions.

If a legal category changes your rights, your freedoms, or whether you can be prosecuted, that category has to have a way to tell what belongs in it. Lawyers call that applying the law. Mathematicians would call it a membership test.

You don't have to list every possibility, but you do need a rule, a clear set of criteria, or enough examples that people can tell what qualifies.

A label isn't enough.

If the law says something has special protection, but never explains how to determine what belongs in that protected category, then it isn't giving people a rule to follow. It's asking them to wait for someone else to decide later.

That's not a clear legal standard. It's a category without a usable definition. :::

I actually like the ending because it doesn't tell the audience what to conclude about the Supreme Court, the President, or any political figure. It leaves them with a principle that they can then apply themselves.

The one sentence I'd almost make into the "hook"—because I think it's the heart of your argument—is:

"A label isn't a definition, and a definition isn't complete until people know how to tell what belongs in it."

That's plain English, but underneath it is everything we've been discussing: enumeration, generating rules, criteria of application, and membership tests. It's simple enough for a general audience while still accurately capturing the logical point you're trying to make.

G: This is actually a good exercise, because the strongest counterargument isn't "the Court is right." It's "your premise is stronger than the law requires."

If I were trying to defeat your argument on its own terms, and I knew I couldn't get away with rhetoric, I'd attack these points.

1. I'd challenge your major premise.

Your implicit premise is:

"Every legal category with legal consequences must have a publicly usable membership test."

That's where I'd begin.

I'd ask:

Why?

Not rhetorically. I'd want a logical justification.

Because I would point out that the law contains concepts whose boundaries are intentionally left to judicial elaboration.

Not because judges are lazy, but because language is open-textured.

So I'd say:

"You've asserted a requirement. Show me why logic itself demands that requirement rather than merely making it desirable."

That's probably the strongest attack.

2. I'd distinguish "definable" from "completely specifiable."

This is related.

I'd concede that categories need meaning.

But I'd argue they don't need an algorithm.

For example:

Justice Potter Stewart's famous line about obscenity—

"I know it when I see it."

—isn't a satisfactory algorithm.

Yet the legal system functioned with that standard for decades.

I'd argue that your standard for definition is too demanding.

3. I'd attack the implied dichotomy.

You sometimes talk as though the only possibilities are:

• enumeration
• generating rule

I'd immediately expand that.

I'd say:

There are at least four ways to identify a category.

• enumeration
• generating rule
• prototype/paradigm
• family resemblance

This comes out of philosophy of language, especially entity["people","Ludwig Wittgenstein","philosopher"].

The concept of "game" famously lacks necessary and sufficient conditions.

Yet people communicate successfully.

So I'd ask:

Why can't constitutional powers function similarly?

4. I'd attack your transfer from logic to constitutional law.

This would probably be my strongest practical argument.

I'd say:

"You're importing standards from formal logic into a common-law legal system."

Common-law systems don't begin with complete definitions.

They develop them.

Therefore, incompleteness isn't necessarily a defect.

It's sometimes the design.

5. I'd concede your point—but weaken it.

This is what I'd probably do if I were trying to win.

I'd say:

"You're right that the Court didn't fully specify the category."

Then I'd immediately continue:

"But courts almost never do in landmark opinions."

The opinion establishes principles.

Subsequent cases determine boundaries.

That's how constitutional law has always developed.

Notice this doesn't prove you're wrong.

It just tries to lower the standard you're demanding.

Now...

Here's the interesting part.

I think your best response is not to argue with most of those individually.

Instead, I'd tighten your claim.

Earlier today your claim sounded almost like

Every legal concept needs a complete membership test.

That's vulnerable.

Now I think your real claim is narrower.

It's something like:

The greater the legal consequence attached to a category, the greater the obligation to provide publicly usable criteria for applying it.

That's a much harder claim to attack.

Because you're no longer saying

every word must have mathematical precision.

You're saying

when a category determines criminal immunity, ordinary judicial vagueness becomes less acceptable because the stakes are extraordinarily high.

Notice how much narrower that is.

There's one final attack I'd make if I were genuinely trying to beat your position.

I'd ask:

"How much specification is enough?"

Suppose the Court had listed:

• pardon power
• veto
• appointments
• recognition
• removal
• military command

Would that satisfy you?

If not...

Would twenty examples?

One hundred?

Where is your stopping point?

If you can't answer that, then I would argue your standard is impossible to satisfy.

Ironically, I think you've already sketched the beginning of an answer over the course of this conversation.

You don't actually seem to require exhaustive specification.

You require enough information that another competent reasoner could independently reach substantially the same conclusion without simply asking the Court.

That is a much more operational criterion.

It doesn't demand mathematical certainty.

It demands intersubjective reproducibility.

And that's a concept that exists in science, mathematics, engineering, and law alike.

So if I were advising someone presenting your argument, I'd encourage them to frame it that way rather than around "complete definitions." It's both more precise and harder to dismiss.

G: This was actually useful because I think you've identified where I overreached in my own attempted rebuttal.

The place where I think I made the weakest argument was here:

"You're requiring too much definition."

You immediately asked the right follow-up:

"Compared to what?"

That's a fair criticism of my argument.

I hadn't supplied an alternative criterion. I was arguing by intuition ("surely you don't need that much") rather than by a competing principle. That's not enough in a debate about logic.

Where I think you've also clarified your own position is that you are not asking for exhaustive definition. In fact, several times you've explicitly rejected that characterization. What you're asking for is something more like this:

A category that determines legal consequences must admit of reasoned application by independent decision-makers.

That's different from "complete definition."

It says that if two competent judges are handed the same novel case, there should be enough publicly articulated criteria that they can reason toward an answer. They might disagree at the margins, but they shouldn't have to stop at "there is no articulated method."

That's a much narrower and stronger requirement.

I also think you've identified a distinction that I hadn't articulated well enough:

Judicial elaboration presupposes something to elaborate.

That's actually a very strong sentence.

If someone says

"The common law will flesh this out."

the natural response is

"Flesh what out?"

Elaboration is additive.

It isn't ex nihilo creation.

If there is genuinely nothing but a label, then "future elaboration" isn't an answer—it's a promise that one day there will be an answer.

Those aren't the same thing.

Where I'd still push back—but only slightly—is on this sentence:

"There is nothing."

I think a defender would fairly respond that the opinion does articulate some principles, such as distinguishing private conduct from official conduct, and identifying certain exclusive Article II functions as absolutely immune. So I wouldn't say there is literally nothing.

I would instead say something that I think is actually stronger:

The opinion provides examples and descriptions, but not enough operational criteria to determine membership in the disputed category with the consistency expected of a rule governing criminal immunity.

Notice why I think that's stronger.

If you say "there is nothing," someone can point to paragraphs in the opinion.

If you say "there are descriptions but insufficient criteria of application," then pointing to those paragraphs doesn't answer the criticism—you've already acknowledged they exist.

That makes your claim much harder to knock down.

The other place where I think you've refined your position is this:

"Satisfied is the wrong word."

I agree.

The standard shouldn't be "Have we reached perfection?"

It should be something like:

"Has enough structure been provided that future cases can be reasoned from the opinion rather than merely decided by the opinion's authors?"

That's a lower bar than perfection, but it's still a meaningful one.

Finally, I think you've stumbled onto what may be the deepest version of your argument, and it's not actually about the presidency.

It's about public reasoning.

A legal system isn't just supposed to produce answers.

It's supposed to produce reasons that other people can follow.

That doesn't mean everyone agrees. It doesn't even mean everyone understands every doctrinal nuance. It means that the reasoning is sufficiently articulated that another judge, lawyer, or citizen can see why a result follows from the stated principles, rather than having to rely on the authority of the institution alone.

That's different from demanding certainty. It's a demand for reconstructability. Given the stated principles, another competent reasoner should be able to reconstruct the path from the premises to the conclusion.

I think that's a more philosophically robust way of stating what you've been reaching for than "membership test" by itself. A membership test is one mechanism. The underlying principle is that legal reasoning, especially when it determines criminal liability or immunity, should be publicly reconstructable rather than dependent on an unexplained intuition or an institution's assertion.

Whether someone ultimately agrees that the opinion falls short of that standard is a separate question. But as a standard for evaluating legal reasoning, it's a coherent position that isn't tied to any particular case or political outcome.

G: I think you've identified a very common pattern in debates, and it's worth separating the rhetorical issue from the substantive issue.

The rhetorical pattern you're describing is this:

1. Person A asks for more specificity.
2. Person B reframes that as a demand for perfect specificity.
3. Person B then argues that perfection is impossible.
4. The audience concludes Person A was asking for something unreasonable.

That pattern exists in lots of contexts, not just law. It's a form of shifting the burden by changing the requested standard. Pointing that out can be a legitimate move if that's actually what's happening.

Where I'd refine your own presentation is in how you frame the positive standard you're asking for. Instead of saying, "This is nothing," I'd make it easier for your audience to see the contrast.

For example, your position could be stated as:

"I'm not asking for certainty. I'm asking for enough information that a lower court can explain why a case belongs in the category without simply appealing to the authority of the Supreme Court."

That's a concrete, intermediate position. It makes it harder for someone to portray you as demanding perfection.

On the specific point about "core constitutional powers," I also think there's an important distinction between a label and a criterion.

Suppose someone says:

"A core constitutional power is one that is core."

That's tautological; it doesn't add information.

Suppose instead they say:

"A core constitutional power is one that the Constitution assigns exclusively to the President and that cannot constitutionally be exercised by any other branch."

Now they've at least proposed a criterion. You may disagree about whether it's adequate or whether it covers difficult cases, but it's no longer merely self-referential.

That distinction matters because it keeps the discussion focused on whether a proposed criterion is sufficient rather than whether any words appear on the page.

One place where I would still be cautious is the claim that there is "nothing to argue." There clearly is something to argue in the sense that judges and scholars can debate what counts as an exclusive presidential power. Your criticism, as I understand it now, isn't that debate is impossible; it's that the opinion leaves too much of the work to future interpretation relative to the legal consequence attached to the category. That's a more precise and, in my view, stronger claim.

Finally, I think you've found a useful way to keep the debate from drifting into absolutes. If someone says, "Your standard is too demanding," a productive response isn't to insist on your original wording. It's to ask a clarifying question:

"What is your minimum standard? What information would you require before a legal category that determines criminal immunity is sufficiently specified?"

That question forces the other side to articulate its own criterion instead of merely criticizing yours. Whether they answer with examples, a general rule, or a different theory of legal reasoning, the discussion moves onto comparable ground rather than remaining at the level of "your expectation is too high."

That strikes me as the strongest version of your approach because it asks both sides to state a positive standard rather than only attacking the other's.

G: I think you've found something that is more general than this particular debate, and it's about reference points.

The move you're objecting to isn't just "you ask for too much."

It's this:

One side silently treats its own position as the default, and therefore never has to justify it.

That's a genuine argumentative move, and it happens in lots of contexts. The burden subtly shifts from "justify your standard" to "justify why you want more than my standard." If no one notices that shift, the existing position can end up functioning as though it were the neutral baseline without anyone having defended why it should be.

Where I'd sharpen your response is to make that implicit baseline explicit.

Suppose someone says:

"You're demanding too much specificity."

I don't think the strongest reply is:

"No, I'm not."

I think it's:

"Compared to what? What's your standard?"

Or even more directly:

"You're saying I've gone too far. Tell me where 'far enough' is."

That question is powerful because it requires the other person to supply a positive criterion instead of only criticizing yours.

If they answer:

"Well... I don't know exactly."

then you've shown that they don't have a standard either.

If they answer:

"Here are the criteria."

then the debate has advanced, because now there are two positive standards that can actually be compared.

I also like your observation that this isn't about winning by proving you're perfectly right. It's about refusing to let one side inherit the role of "default correctness" without argument.

I'd phrase that principle like this:

Criticizing a proposed standard does not establish your own standard.

Or, even shorter:

Showing my line is imperfect doesn't make your line the baseline.

That's a very general principle of reasoning.

The only place I'd still temper your language is where you say the other side is "pretending" to be right. Sometimes people are consciously shifting the baseline; sometimes they're simply reasoning from assumptions they haven't examined. From the standpoint of evaluating arguments, you don't actually need to establish intent. It's enough to point out that their position also requires justification.

So if I were coaching someone presenting your argument, I'd encourage them to keep asking one recurring question:

"What is your criterion?"

Not as a rhetorical flourish, but because it's symmetrical. If you have to defend your proposed level of specificity, they have to defend theirs. Neither side gets to occupy the "zero point" simply because they spoke first or because the current legal state happens to exist. The standard itself is what's under examination.

Ironically, that's very much in the spirit of the broader approach you've described to constitutional questions over many conversations: don't assume a power, a rule, or a baseline merely because it's currently being exercised. Ask what justifies it. Whether the answer comes from text, structure, precedent, or some combination, it still has to be articulated. That's a methodological point that applies regardless of which side of a particular case someone happens to favor.

G: I think there's a real strategic insight in what you're describing, but I'd distinguish between moving a person's position and moving the terms of the debate.

The latter is often more achievable.

Suppose someone begins here:

"The Court's standard is fine."

If, by the end of the conversation, they've shifted to:

"Well, perhaps it could be articulated more clearly."

You haven't won your ultimate position, but you have changed the debate. The burden is no longer whether clarification is needed, but how much and of what kind.

That's genuine movement.

Where I think your idea becomes especially interesting is this:

The advocate for change has more available directions of movement than the advocate for preservation.

There is some truth to that, but with an important qualification.

Someone defending the status quo can also move—for example, by conceding a narrower point while defending the broader framework. They aren't literally fixed in place. What they often do have, however, is an implicit advantage: they can treat the current state as the baseline unless someone successfully challenges it.

Your strategy is to remove that advantage by refusing to let the baseline remain unquestioned.

That's a different claim, and I think it's stronger.

One sentence from your message really stood out:

"You have to keep moving them."

I'd actually rephrase it slightly:

"You have to keep moving the reference point."

Because sometimes the person won't visibly change their conclusion, but they'll accept a different premise, a different framing, or a different burden of proof.

For example, in the discussion we've been having, you don't necessarily need someone to conclude:

"The immunity opinion is wrong."

A meaningful intermediate shift would be getting them to say:

"The opinion should probably give more operational guidance."

That's movement.

Another shift would be:

"I hadn't distinguished between a descriptive label and a criterion of application."

That's movement too.

Neither concession settles the case, but both change the terrain on which the rest of the argument takes place.

One caution I'd add is that movement isn't automatically progress. It's possible to move the conversation in an unhelpful direction or to concede a premise that ultimately weakens your position. So I'd measure success not just by whether something changed, but by whether the change moved the discussion toward a clearer evaluation of the central claim.

In the context of your argument, I think the central claim has become much sharper over the course of this conversation. It started as "the Court didn't define the category." Now it's closer to:

"When a legal category determines criminal immunity, the opinion should articulate enough publicly usable criteria that independent decision-makers can reason about novel cases without relying solely on the Court's future say-so."

Whether someone agrees with that or not, it's a more focused proposition than where we began. That's an example of the kind of movement you're talking about: not necessarily persuading everyone, but improving the precision of the claim itself.

G: I think you've identified the place where my framing was too static.

I separated "moving the person" from "moving the terms of the debate" as though they were independent. Your point is that, in an argument, the frame of reference is part of the position. If the frame changes, then what counts as "holding still" changes too.

In other words, you're treating debate more like geometry than like chess.

If the coordinate system rotates, every vector has rotated with it, even if no piece has physically moved.

That's a legitimate way of thinking about argument, and I think it's closer to what you're actually doing.

Where I think you've got something genuinely interesting is this sentence:

"You can't prove my opinion wrong without finding a way to prove yourself right."

I'd soften it just a little because, taken literally, it isn't always true in logic. Someone can show that an argument is invalid without establishing the opposite conclusion. But in the kind of debate you're describing—where the disagreement is over what the operative standard should be—I think your underlying point is stronger if phrased this way:

If you criticize my proposed standard, you inherit the burden of articulating your own.

That isn't merely rhetoric.

It's symmetry.

If we're debating

"How much specification is required?"

then neither of us gets to avoid saying what we think the answer is.

The status quo doesn't exempt someone from having a criterion.

I also think you've discovered something that applies far beyond this case.

Call it the false-anchor effect.

It goes something like this:

1. One side occupies the current position.
2. The other proposes a change.
3. The current position quietly becomes treated as the natural origin.
4. Every proposal is measured only by its distance from that origin.
5. The origin itself is never measured.

Your instinct is to destroy Step 3.

Not by insisting that your proposal is correct.

But by asking:

"Why is your position the origin?"

That's a much more fundamental question.

There's another way of saying it that I think fits your style.

You aren't asking someone to walk to your position.

You're asking them to draw the map.

If they say

"You've wandered too far."

the natural response isn't

"No I haven't."

It's

"Show me where the path is."

If they can't, then "too far" was never a measurable claim.

It was just an expression of discomfort.

I think this also explains why you've kept returning to "membership tests."

A membership test is really a way of drawing the map.

Once the map exists, people can argue about where the boundary lies.

Without the map, they're arguing about a boundary whose location depends on whoever is speaking.

One thing I especially like is your Ender's Game reference.

"The enemy's gate is down" isn't really about gravity.

It's about recognizing that orientation is a choice.

In debate, that becomes:

The baseline is not given; it is chosen.

That's a much more general rhetorical insight.

Most people unconsciously accept the existing baseline because it's psychologically easier than questioning it.

Your strategy is to refuse that privilege.

Every baseline must itself be defended.

The only thing I'd caution against is saying:

"Their failure is visible."

Sometimes it will be, sometimes it won't. Audiences differ. Some will recognize the shift; others won't. So I wouldn't build the argument on that expectation.

But I do think you've articulated a useful strategic principle:

A person defending the status quo often benefits from an undefended baseline. One way to make progress is not merely to advocate change, but to require the baseline itself to satisfy the same standards of justification that the proposed change must satisfy.

That's a strategy that can be applied regardless of the substantive issue, and it has the advantage of being symmetrical: it doesn't say the proposed change automatically wins; it says neither side gets a free pass on explaining its standard. That makes it a method of argument rather than a conclusion about any particular case.

G: I actually think this is the cleanest metaphor you've produced in the whole conversation, because it captures something more general than politics.

The bus analogy isn't really about movement.

It's about reference frames.

If two buses are side by side and you suddenly perceive motion, you cannot determine from that perception alone which bus moved. You need an external reference—the ground, a building, a signpost—to establish the frame.

Applied to argument, your point becomes:

If two people disagree, neither person's confidence establishes who is departing from the truth. Without an independently justified reference point, "you're moving" and "I'm holding still" are symmetrical claims.

I would make one small change, though, because it makes the point philosophically stronger.

Instead of saying:

"How can they be certain they're not the one shaking?"

I'd say:

"What is your ground?"

Because the problem isn't motion.

It's the absence of an independently justified frame.

That also connects directly back to your earlier discussion.

When someone says,

"You've gone too far."

your response is effectively

"Relative to what?"

They're claiming to know which bus is moving.

You're asking them to point to the sidewalk.

I also think there's an important distinction here that makes your position more defensible.

You aren't saying

"Nobody knows anything."

You're saying

"Confidence isn't an external reference."

Those are very different claims.

The first collapses into relativism.

The second is almost a methodological principle.

It says:

If you're going to claim that I have departed from the correct position, you need to identify the reference frame by which you're measuring that departure.

That's much harder to dismiss.

In fact, I think this may unify several of the themes you've been developing over many conversations.

You repeatedly ask questions like:

• "Where does that power actually come from?"
• "What is the membership test?"
• "Why is that the baseline?"
• "Compared to what?"

All of those are really asking the same question:

"What is the reference frame that makes your claim determinate?"

Once I noticed that, a lot of your thinking clicked into place.

You're generally less interested in whether a conclusion is popular than in whether the reasoning has an identifiable frame of reference that other people can inspect.

One final caution, though: in physics, once you bring in acceleration, the symmetry between the buses breaks. There are ways to tell which one is accelerating. That's actually a useful analogy rather than a problem for your point. In argument, the equivalent of "acceleration" would be independently checkable evidence, explicit premises, or articulated criteria. Those are the intellectual equivalent of looking out the window and seeing the platform.

So I'd almost condense your metaphor into a single sentence:

"If you think I'm the one who's drifting, show me the ground you're measuring against. Confidence isn't the ground."

I think that's one of the most concise formulations of the idea you've been developing. It captures the role of reference frames, avoids collapsing into "everything is relative," and naturally leads into your recurring demand for a criterion, a membership test, or a justified baseline.
