The Spear and the Shield
A merchant of the State of Chu sells a spear that pierces all defenses, and a shield that no spear can pierce. He is asked, in turn, what happens when one strikes the other — and finds language itself has no answer.
CONTRADICTION INDEX
0.000
矛盾 mujun.study
A scholar's desk for the formal study of contradiction — where mahogany meets monospaced readouts, and every paradox is bound, stamped, and catalogued.
The Liar's Confession
A Cretan declares that all Cretans lie. The sentence devours its own footing — truth and falsehood spin in mutual citation, and the inkwell tips. The desk is left with a wet stain shaped like a question.
Ship of Continuance
A vessel returns to harbor with every plank replaced. Is it the same ship? The original timbers, reassembled in a barn, claim equal title. Two ships now — one of memory, one of matter — both pretending to be one.
The Unmoved Arrow
In each instant of its flight, the arrow occupies a single space equal to itself — thus, in each instant, it is at rest. The sum of rest cannot be motion. And yet the arrow strikes, leaving a hole in the door of certainty.

Margin notes, struck this week
Re-read Han Feizi tonight. The merchant's spear and shield are not a contradiction in things, but in selling — the paradox is mercantile.
Russell's set looks different by lamplight. The sci-fi readout flickered while I read. Coincidence, or was the set watching itself?
Cataloguing today: filed Newcomb's Box under both «causation» and «non-causation». The drawer must contain its own classification dispute.
mujun.study — bound and stamped in the spring of 2026. Set in Libre Baskerville, with spine labels in Bebas Neue and margin notes in Special Elite. The desk lamp is hand-wired.
