Volume III — weigh

Le Crible.

This is not a book about AI — it is a discernment manual, and the model output is only one of its ten terrains. Its starting question is the only one left when anyone can produce impeccable text for free: how do you tell that a text is worth something? The answer fits in two master questions — what did it cost the author, what escaped him — deployed into three laws, ten keys borrowed from the best reading traditions, from Popper to Ginzburg, Austin to Peirce, and four speeds depending on the stakes: five minutes at customs, twenty at inspection, an hour at the workshop, a day for the investigation. Then the book does what almost no manual dares: it turns on itself — twelve traps of the sifter with their antidotes, and the boundary stone, the page where the instrument learns to stop, before works of art, people you are bound to, and those rare utterances that don't report the world but call into it.

“Truth leaves traces; emptiness is free.”Le Crible, part one

“Never zero, never one.”Le Crible, the guardrails

Inside

Nine parts, plus a program

The route runs from the instrument's philosophy to its daily handling — and ends with twenty-one days of exercises, because discernment isn't read: it is trained.

The philosophy of the Sieve — why truth leaves traces; the reading machine; the reader's mold.
The three laws — look for the constraints; look for the roughness; remove before adding.
The ten keys — exegesis, philology, genealogy, genetic criticism, Austin, Ginzburg, Ricœur, Bayes, Peirce…
The four speeds — customs, inspection, the workshop, the investigation.
The twelve traps — from the genetic fallacy to the pleasure of demolition, each with its antidote.
Ten case studies — the online review, the ad, the speech, the press, the scientific paper, the contract, the model output, the conversation, hot media, the work of art.
The Sieve against itself — the degenerations, the Sieve in front of others, and the boundary stone.
Twenty-one days — the training program, day by day.
The theory — information as the reduction of possible worlds.

For whom

Who it's for

Any reader — citizen, journalist, decision-maker, student. It is the collection's widest volume: what it teaches serves in front of an online review as well as a contract, and it reads on its own — it simply gives more alongside the other two.

What next

This site's test bench is a foretaste of its logic: demanding that a text show where reality holds it. Edition in preparation, out in 2026. The volume is written in French. Back to the collection →
