PUT UP OR SHUT UP. No. You are just going off on a Red Herring. Show where your system defeats Godel's proof of the inability to prove consistancy. PUT UP OR SHUT UP. (of course, your problem will be you don't understand that proof, as you just don't understand "complicated" logic since you think Prolog can do anything. > >> You should know better than that, but you don't, because you really >> are too stupid. >> >
