Naturally I also spoke of these matters to my comrades, who to my great astonishment reacted with derision and disbelief or with anxious defensive-ness. I wondered at the sureness with which they could assert that things like ghosts and table-turning were impossible and therefore fraudulent, and on the other hand at the evidently anxious nature of their defensiveness. I, too, was not certain of the absolute reliability of the reports, but why, after all, should there not be ghosts? How did we know that something was "impossible"? And, above all, what did the anxiety signify? For myself I found such possibilities extremely interesting and at-tractive.
