name: mind-thesis-and-argument
description: Use when building the central argument of a Mind article — stating a sharp thesis and constructing a valid, sound argument for it. This is the core of an analytic-philosophy paper: explicit premises, a valid inference to the conclusion, and defensible premises. Structures the argument; it does not generate the philosophical content for you.

# Thesis & Argument (mind-thesis-and-argument)

At Mind the paper *is* the argument. A finding, an intuition, or a clever example is not yet a
contribution until it is the conclusion of an **argument the reader is rationally compelled to take
seriously**: a sharp thesis, explicit premises, a valid inference, and premises that survive scrutiny.
This skill turns an idea into that argument.

## When to trigger

- You have an intuition or insight but not yet a stated thesis
- A reader said the paper is "suggestive" but "doesn't actually argue for the claim"
- You need to lay out premises and check that the conclusion really follows
- The argument feels strong but you cannot say which premise does the work

## Build the argument

1. **State the thesis.** One sentence, in the strongest defensible form. It must be **deniable** — a
   competent peer could reject it. If no one could disagree, it is not a thesis.
2. **Make the argument explicit.** Write the premises and the conclusion as numbered steps. The
   reader should see exactly **which claims**, taken together, yield the thesis.
3. **Check validity.** Does the conclusion *follow* from the premises? If there is a gap, name the
   hidden premise and add it — then defend it (a suppressed premise is where papers die).
4. **Check soundness.** Are the premises **true / defensible**? For each premise, give the supporting
   reason, distinction, or example. The most contestable premise needs the most support.
5. **Identify the load-bearing premise.** Say which premise the whole argument turns on. That is where
   objections will land (hand to `mind-objections-and-replies`), so defend it hardest.
6. **Calibrate the conclusion.** Claim exactly what the argument earns — no more. State **scope and
   qualifications** explicitly; an overclaim invites a cheap refutation.

## Forms of argument Mind accepts

- **Deductive** — premises entail the conclusion; the work is defending the premises.
- **Counterexample** — a single clear case refutes a universal claim; make the case undeniable.
- **Inference to the best explanation** — your thesis explains the data of the debate better than rivals; show the comparison.
- **Reductio / dilemma** — derive an unacceptable consequence from the opposing view, or trap it between two bad options.
- **Transcendental / presupposition** — show the opponent's position presupposes your conclusion.

Where any of these uses formal apparatus, **accompany it with informal exposition** so a non-specialist
philosopher can follow the move (a Mind expectation).

## Anti-patterns

- A thesis no one could deny (a truism dressed as a discovery)
- Asserting the conclusion instead of arguing to it ("clearly, …")
- An invalid step papered over by rhetoric — find the missing premise
- The load-bearing premise stated but never defended
- Overclaiming scope, then being refuted by an easy counterexample

## Output format

```
【Thesis】one deniable sentence
【Argument】numbered premises → conclusion
【Form】deductive / counterexample / IBE / reductio / dilemma / transcendental
【Validity】does the conclusion follow? hidden premise named? [Y/N]
【Load-bearing premise】the one to defend hardest
【Scope】qualifications / where the claim stops
【Next】mind-objections-and-replies
```
