This is such an obvious fallacy.
Can we really make something true just by believing it? How about a concrete example?
If you sincerely believe your onion rings are french fries, do they become french fries? If you sincerely believe that you're a frog, do you become a frog? You might leap in the air, but you still will not be a frog. When it comes to concrete, familiar objects, no one falls for the sincerity myth. We all know there's an objective reality that exists on its own, despite what we may believe about it -- and no matter how sincere we are. If we accept the idea of objective truth when dealing with trivial questions, then logically we have to accept it when dealing with big questions about God and morality as well."
--Charles Colson
Do the folks on the "E" side have one, based on their beliefs, on how it fits into the 'fact' of Evolution?
