Re: ONT 3 laws of logic




I have been advised to change my diagram; you may want to click reload on
it:

http://robustai.net/mentography/3laws.jpg

In KIF, this would read something like :

(=> Identity (and LEM NonContradiction))

which I intertert to mean that the law of the excluded middle, and the law
of non contradiction do not hold *unless* the law of identity holds.   The
diagram says more than the KIF above ... maybe somebody can help me add
quantification to the formula.
