Re: Concept_sitting

It was clear for me that you did only speak in a mathematical point
of view and not about languages.
But,  beeing totally ignorant in this domain (maths), it still
unclear to me what do you do mean when you say 'no speaker would
naturally emit a sentence like "this sentence is false"'
Aren't any sentence  admitable as far as they are grammatically
correct ?
