That there are passages in Dean Spanley’s conversation that have sometimes jarred on me, the reader will readily credit. But the more that his expressions have been removed from what one might have expected of a man in his position, or indeed any member of my club, the more they seemed to me to guarantee his sincerity. It would have been easy enough for him to have acted the part that it is his duty to play; but difficult, and I think impossible, to have invented in such meticulous detail the strange story he told me. And for what reason? Upon the authenticity of Dean Spanley’s experience I stake my reputation as a scientific writer. If he has deluded me in any particular let scientific bodies reject not only these researches, but any others that I may make hereafter. So sure am I of Dean Spanley’s perfect veracity.

Should doubt be expressed of a single page of these talks, and the case against it be made with any plausibility, it is probable that I shall abandon not only this line of research, but that my Investigations into the Origins of the Mentality of Certain Serious Persons, the product of years of observation, may never even be published.
