Abstract

A formal system of “questions” and “propositions” conceived by C. Piron and claimed to yield by interpretation quantum mechanics as well as all other known physical theories is examined. It is proved that the mentioned system is syntactically self-consistent in the sense of the theory of models. However, it is found that the mentioned formal system possesses certain syntactic characteristics in consequence of which qualification of this system as a generator of quantum mechanics by interpretation encounters semantic obstacles so grave that they annihilate any relevance of such a qualification
