FROM AXIOMS you DERIVE THEOREMS!
Nobody CARES if SomeModel |= 'this is not derivable from your
axioms"
looks TRUE!
IT's not DERIVABLE FROM THE AXIOMS! END OF STORY!
Nothing Mathematically INCOMPLETE ABOUT IT!
LOGIC is an ARTS DEGREE on SLAGGING OFF COMPUTER PROGRAMMERS because
you PROVED YOURSELVES STUPID!
1 Godel proved LOGIC DOESNT WORK!
2 Everyone FELL FOR IT for 100 years
3 Literacy Students took up volumes of texts on logic
and Swamped any discussion with THAT WONT WORK because "TEACHER IS
RIGHT" arguments!
Any and All mathematical logicians posting to SCI.LOGIC have all been
verbally abused 100, 1000 times or more until they all left.
Me included.
