Source passage

Source text · mention only

We can only apply the same sort of tests in the one case as in the other. We must discount all those facts which might possibly have been obtained normally, or by telepathy, and pin our faith on those which could not possibly, or conceivably, have been obtained in this way. Similarly, we must assume that all psychic photographs represent normal markings upon the plates, or the emotions or thoughts of the sitter, or the vital radiations issuing from his body, until indisputable proof to the contrary be forthcoming. (It may be added that some very striking evidence of identity has been obtained in this manner, from time to time in the past, and is now being obtained in various circles both in this country and abroad.)
