The weakness of the attack lies in its lack of discrimination. It is possible that psychic surgery is a hoax, that plants cannot really read our minds, that Kirlian photography (photographing the "life-aura" of living creatures) may depend on some simple electrical phenomenon. But to lump all of these together as if they were all on the same level of improbability shows a certain lack of discernment. The same applies to the list of "hoaxes." Rhine's careful research into extrasensory perception at Duke University is generally conceded to be serious and sincere, even by people who think his test conditions were too loose. The famous fairy photographs are quite probably a hoax, but no one has ever produced an atom of proof either way, and until someone does, no one can be quite as confident as the editors of Time seem to be. And Ted Serios has never at any time been exposed as a fraud — although obviously he might be. We see here a phenomena that we shall encounter again in relation to Geller: that when a scientist or a "rationalist" sets himself up as the defender of reason, he often treats logic with a disrespect that makes one wonder what side he is on.
