The Book of Prophecies (Libro de las profecías)
Christopher Columbus, with Gaspar Gorricio, 1501–1502 — prophecy.
At the end of his life, Columbus assembled a manuscript of biblical and Joachimite prophecy to prove that his voyages were a step in a divine timetable — the recovery of Jerusalem and the approaching end of the world. It is the archetype of motivated reasoning: not evidence gathered to reach a conclusion, but a conclusion already fixed and evidence quarried to justify it. He states the method himself. The engine’s answer is the public Model Card — every weight and source shown, so the reasoning can be audited rather than asserted.
Why the engine keeps this on the shelf
A conclusion fixed first and evidence quarried afterwards to justify it — the failure mode the public Model Card exists to expose, since every weight and source is shown rather than asserted.
The record
- Columbus assembled the Libro de las profecías between September 1501 and March 1502, with additions running to about 1505, most of the transcription done by the Carthusian monk Gaspar Gorricio.
- Its argument sets four preconditions for Christ's return — worldwide Christian preaching, the finding of the Garden of Eden, a final crusade to recover Jerusalem, and the appearance of a Last World Emperor, a role Columbus assigned to Ferdinand and Isabella.
- By his own reckoning, leaning on Augustine, Columbus concluded that the world had roughly 155 years left to run.
- The manuscript waited until 1991 for a complete facing-page English edition, produced by Delno C. West and August Kling for the University Press of Florida's Columbus Quincentenary Series.
Marked passages
Neither reason, nor mathematics, nor maps were any use to me: fully accomplished were the words of Isaiah.
The confession of motivated foresight — maps discarded, prophecy retrofitted onto a decision already made. The Model Card exists precisely so no weight can be quarried after the fact to fit the answer.
In the author’s own words
que para la ejecución de la impresa de las Indias, no me aprovechó razón, ni matemáticas, ni mapamundos: llanamente se cumplió lo que dijo Isaías
Libro de las profecías, prologue letter to Ferdinand and Isabella, c. 1501 (modernised spelling) — 'for the execution of the enterprise of the Indies, neither reason nor mathematics nor world-maps helped me; what Isaiah said was plainly fulfilled'
Then and now
By July 2026 a running database of court decisions had recorded 1,668 cases worldwide in which filings relied on fabricated AI-generated citations — authority produced to fit a conclusion already written. Source: Damien Charlotin, AI Hallucination Cases database, July 2026
The same database logged 140 new cases in the nineteen days to 9 June 2026, just under eight a day, and counts only the fabrications a court actually noticed. Source: Damien Charlotin, AI Hallucination Cases database, June 2026
