Even Sklansky, the Messiah of Logic, agrees that if the two principles are competing there is no logic for automatically determining their correct balance.

If they are exactly equal and opposite, then I agree. But what if you can assign values or weights to the various values, like vector forces in cartesian space which go in different directions, but not exactly opposite? Then there is a nondegenerate resultant vector which indicates the appropriate action via logic.

If the two competing values are almost opposite and almost equal in magnitude, but not exactly, then a very precise determination of these values (using logic) is needed to get even approximate information about the resultant vector.

I think the gypsy example is a case in which the two are competing but not exactly opposite and the magnitude is similar, but not exactly the same.

DS was referring to two absolute statements (A) and (not A) exactly, not something close.

Do you not agree that there is a key difference there?
