Cassaruby - I choose not to believe in fairies, except for metaphorical fairies. Like grimms fairy tales is a book I like.
I think this is probably not the case. Let's try an experiment: For the next 10 minutes, believe that you're an elephant. Not in a metaphorical or mystical sense; a literal elephant, weighing six tons, with tusks and a long trunk. I don't think you could honestly believe it. We don't choose our beliefs, though we can choose to ignore evidence that is contrary to what we already believe, which certainly influences or strengthens/weakens beliefs.
