How do you "prove" photography to a blind man?

One analogy psychics sometimes use to claim that we "normal" people can't understand their abilities is to ask a question like: How would you prove to a blind man that photography exists?

The implication, of course, is that psychics have a sense that you do not, just as you have a sense (sight) that a blind man does not. Skeptico tells us exactly how you could prove the existence of photography to a blind man using the scientific method. Even better, he completely turns the question around on the questioner to show why the "evidence" supposedly used to "prove" psychic phenomenon is so weak and unconvincing.

Beautiful. No wonder Skeptico is rapidly becoming one of my favorite skeptics' blogs.
