apparent undeniable logic has kept many trapped in Borganizations like JWs with statements such as IF this is SO and that is SO than THESE must be SO... and if you do that often enough you have built a house of cards on a stairway of assumptions which seems completely logical and rational and impossible to deny...and thus you are trapped. the trick is that in reality many things SEEM to be so sometimes, not always. many things APPEAR to be as the belief about them describes, but not always... the world often works on a fuzzy logic rather than a binary logic, its not always THIS OR THAT, its often THIS THAT or THE OTHER with overlaps that do not total 100%.
examples of religious logic:
If four gospels mention Jesus than he MUST have existed.... really? if the same lie is told by four APPARENTLY different sources, does that make it true now?
Jesus is the jewish messiah because Moses prophecy was fulfilled in him..... Moses was a real person because Jesus mentioned him by name..... did we prove anything?
You prayed to God and what you prayed for happened, therefore God must exist.... I prayed to no one but what I desired just happened to happen...therefore?
much of logic is based on circular definitions 1+1 = 2 because 2-1 = 1, what is forgotten is that symbolic language is just that a language and the symbols are NOT the things pointed to by themselves...the point to something outside themselves.. one apple plus one orange equals two objects...not two apples not two oranges... the symbols can be misused if you assume that 1 +1 = 2 of the same thing.
