A rational donkey would starve to death between two totally identical piles of hay [Buridan, by PG]

We need to know the meaning of 'and', prior to its role in reasoning [Prior,AN, by Belnap]
Maybe introducing or defining logical connectives by rules of inference leads to absurdity [Prior,AN, by Hacking]

Without magnitude a thing would retain its parts, but they would have no location [Buridan]
