[FOM] possibility and probability/ Beziau

[Lotfi A. Zadeh]

Dear Dr. Beziau,

     Thank you for your comment. Please note that p may be a proposition 
drawn from a natural language. Neither modal logic nor probability 
theory deal with such propositions. Example. Most Swedes are tall. How 
would you differentiate between, "It is possible that most Swedes are 
tall" and "It is probable that most Swedes are tall?" When p is a 
proposition drawn from a natural language, possible is not bivalent,as 
it is in modal logic. Thank you for bringing to my attention the work by 
Pedro Baltazar, "Probabilization of Logics: Completeness and 
Decidability." My understanding is that this work does not deal with 
propositions drawn from a natural language. Dealing with such 
propositions raises many problems which do not arise when p is a crisp 
proposition.

Sincerely yours,

Lotfi Zadeh
