Sorry Pei, you are right, I sloppily mis-stated! What I should have said was:
" the result that the NARS induction and abduction *strength* formulas each depend on **only one** of their premise truth values ... " Anyway, my point in that particular post was not to say that NARS is either good or bad in this aspect ... but just to note that this IMO is a conceptually important point that should somehow "fall right out" of a probabilistic (or nonprobabilistic) derivation of NARS, rather than being achieved via carefully fitting complex formulas to produce it... ben g On Fri, Oct 10, 2008 at 4:48 PM, Pei Wang <[EMAIL PROTECTED]> wrote: > On Fri, Oct 10, 2008 at 4:24 PM, Ben Goertzel <[EMAIL PROTECTED]> wrote: > > > > In particular, the result that NARS induction and abduction each > > depend on **only one** of their premise truth values ... > > Ben, > > I'm sure you know it in your mind, but this simple description will > make some people think that NARS is obvious wrong. > > In NARS, in induction and abduction the truth value of the conclusion > depends on the truth values of both premises, but in an asymmetric > way.
