I remember a while back finding an anecdote about a paper in set theory from the early 20th century establishing an equivalence between two concepts (I think, but I’m not sure, that it was the axiom of choice and the well-ordering principle). The story goes that the paper was rejected from one journal with the comment that it was not interesting that two true statements imply one another, and rejected from another journal on the grounds that it was not interesting that two false statements imply one another.

I’m having trouble locating which paper this was. Google isn’t turning anything up with the search queries I tried, and ChatGPT hallucinated a nonexistent paper and an invalid Wikipedia link.

Any ideas what paper this is?
