I did not deny the concept (whatever that means) - I was simply asking  
for a clear explanation of it.

"intuitionistic truth" is a concept, not a statement or a proposition,  
so I don't understand what it would mean to demonstrate it...

Anyway, Kripke semantics and such are fine, as technical formal tools,  
but I think all serious intuitionists agree that they have nothing to  
do with the *intended* semantics of intuitionistic logic, which is in  
terms of informal, intuitive notions of proof and provability. And  
that's what my query is about.

Best, Panu
