Lessons (8)
- Choose the entry point by your purposeChoose the entry by your purpose: type, object, find, or debate. Do not write down numbers that move.
- Verifying that "no one has said it yet"Exhaustiveness is impossible, so write down the range you searched. Stating the range is not modesty but defence.
- Where quotation, summary and plagiarism divideThere are only two axes: are the words the original's, and did you show the source? Rewording without a source is still plagiarism.
- Naming, and what cannot be verifiedA name makes debate easier and, at the same time, stops the content from being questioned. If you name it, define it too.
- Anatomy of a Controversy — Three Hundred Years of Debate Over PricesA strong debate leaves behind the question of 'what must be verified to settle the matter?'. Rather than focusing on winning or losing, one should examine the verification methods that remain.
- The Art of Disclosure — The Surplus Shown, the Blank Space UnseenPublication is a revolutionary practice. But a publication that does not state what it has omitted becomes a machine for printing illusions.
- The Archaeology of Names — Gresham and TulipsBoth the law's name and the bubble's story were recast later. Investigate the dates of the name and the substance separately.
- The art of opposition — Frame it in the form of a strong opponent.A good dissenting opinion presents the opponent's argument in its strongest form, clearly states its own criteria, and leaves a verifiable prediction.
Case studies — applied in the materials (10)
- Gresham and the recoinage Britain 1560–1858 London, and a study of a later age
§4. A case where the name and the law do not match. Read the sequel to "a twist of history" in the original. - "The Crime of 1873" United States the 1870s America, the West and the South
§4. The scene where naming becomes politics. Both the claim and the rebuttal are written. - Newton's Great Recoinage Britain 1696 The mint in the Tower of London
The great recoinage. Material for seeing how the record of a controversy survived. - The changing of the reserve currency Britain 1944 The conference hall at Bretton Woods
Bretton Woods. The record of a delegate who put forward a plan against his own country's interest. - The century of silver and the price revolution France 1566–1568 A study in the Parlement of Paris
Section 5. Please read this while considering the seeds of the quantity theory of money, including the reservation that "Bodin was not the first." - Louis XVI and the reformers France 1781 The printing houses and bookshops of Paris
Section 6. The missing column is the most eloquent—a cautionary tale regarding the practice of public disclosure. - The anchor groans United States 1960 Washington, the Congress
Section 8. A warning, voiced in parliament, about a flaw written into the system's very blueprint. - We are bankrupt Greece December 1893 The rostrum of the Chamber
The famous quote, "Unfortunately, we are bankrupt," is found neither in parliamentary records nor in contemporary newspapers. This section traces the verification process that revealed its sole source to be a single memoir. - Paper money without paper China from 2014 The room where the research began
When writing about an ongoing event, where does one draw the line? Research began in 2014, trials between 2019 and 2020—this is a passage where the decision was made to write only the verifiable years. - Chop mark Mexico 17th–19th centuries The global flow of silver
Some studies suggest around one-third, while some researchers believe it exceeds 40%. This is a practical example of how the direction of silver flow can be stated with certainty, even when a wide range remains in the figures.
