Proof
This course is a half-credit on the one competence everything else depends on: establishing that a thing is true. Not logic — an argument can be perfectly valid and built on a source that does not exist. Not skepticism as an attitude, which is cheap and produces nothing. A procedure: where did this come from, who handled it, does it trace to a source, what would change my mind, and what did I fail to determine. Its central claim is that provenance beats inspection. Every forgery in the course that was actually broken was broken by a fact the forger did not know mattered — a Persian word in a Latin charter, a pigment not manufactured until after the painter died, titanium white in a canvas that predated it — and never by looking harder, because looking harder is what the forger prepared for.
Each unit works a real case and then runs the check the fabricator did not anticipate. The course holds a firm position, stated and argued in the first unit: things can be established, it takes work, here is the work, and here is how to say how confident you are. Two registers are refused outright. The debunker voice, delighted by other people's errors, produces a student who is good at scoring and bad at being wrong — so every worked failure here is one that fooled serious people, several of them the people who wrote the reference works. The corrosive voice, that nothing can be known and everything is manufactured, is worse than credulity because it is unfalsifiable and feels like sophistication. On the particular claims it uses as material the course withholds its own read, because supplying the answer removes the exercise, and a correctly reasoned "undetermined" with the stopping point named scores as well as a correct verdict. It ends in a researched verdict on a live contested question, every source traced to origin, the student's own uncertainty stated, and a falsifier he wrote in advance and would have to honor.
This course does not have an opening date yet. Founding Families watch the ladder fill in — at a price that never moves.
