The Cold Shower

Self-refutation does not travel like hope. That is exactly why it lives here, in a permanent room of its own, instead of quietly disappearing the way the inconvenient argument always does on a growth channel.

The rule: never post the optimistic fragment without, somewhere soon, posting the shower that tests it. At the end of every part of the book is the strongest available case against that part — stated in its most persuasive form, with no flinching — and only the optimism that survives the cold water is kept. If a month passes with no public self-argument, something is drifting.

The hardest one is already named: Walter Scheidel's claim that only catastrophe has ever truly leveled a society. If he's right, the whole book is a lullaby. That shower gets taken in full, in public, when its essay lands.
