The informal statement above should be read metaphorically rather than literally. PT aint' no logic due to lack of truth functionality, and the 'reduction' to logic, which you've failed to prove by the way, is possible only in trivial and uninteresting cases.

What Jaynes did in his derivation of the sum/product rules has got nothing to do with your mindless playing with formulas. See the argument from authority in my previous messages.

That's assuming that P(p1|p2) even makes sense. More general formulation of such independence is just P(p1 and p2) = P(p1)* P(p2). Received on Sun Jun 11 2006 - 05:43:16 CEST
