Is there anybody out there who hasn't heard some debater quip, "Extraordinary claims require extraordinary evidence?"
I'm betting not.
How many people actually stop and consider the rhetorical device they're using?
I'm betting not that many, else we'd hear it much less!
At any rate, I've got a very simple and straight-forward example of an instance where the claim, "Extraordinary claims require extraordinary evidence" can easily be shown false.
So I locked horns with PhillyChief and John Evo, again, this time it was over the following comment from PhillyChief – who if I remember correctly – claims to be a scientifically-minded rationalist atheist:
Prayer helps no one but the one praying, providing a euphoria and calming effect, which could be comparable to ejaculating.
–PhillyChief
I felt that was an odd statement for a scientifically-minded rationalist to make, but was not surprised that it came from a sarcastic atheist who claims to be "almost always right", and so I replied,
How would you know? Where is that "demonstrable evidence" you're so fond of? Aside from being grossly unscientific, statements like the above appear contradictory alongside appeals to soft atheism as you've recently made on my site.
