Core Inconsistency

[Joseph Vidal-Rosset]

Dear colleagues,

My contribution to the World Logic Day: a proof that Core logic (that is
Neil Tennant's logical system) entails an inconsistency.

Comments are welcome and, of course, if my argument is not a proof, I will
apologize and I will delete this webpage.

Best wishes, and Happy New Year !

Joseph Vidal-Rosset
