"I do not conceal from myself the consequences of such sincerity. It requires a good deal of boldness to insist on affirming, in the name of positive science, the POSSIBILITY of these phenomena (wrongly styled supernatural), and to constitute one's self the champion of a cause apparently ridiculous, absurd, and dangerous, knowing, at the same time, that the avowed adherents of said cause have little standing in science, and that even its eminent partisans only venture to speak of their approval of it with bated breath. However, since the matter has just been treated momentarily in fugitive writings by a group of journalists whose exacting labors wholly forbid a study of the psychic and physical forces; and since, of all this multitude of writers, the greater part have only heaped error upon error, puerility upon extravagance; and since it appears from every page they have written (I hope they will pardon me) that not only are they ignorant of the very a, b, c of the subject they have so fantastically treated, but their opinions upon this class of facts rest upon no basis whatever,—therefore I have thought it would serve a purpose if I should leave, as a souvenir of the long wrangle, a piece of writing better based and buttressed than the lucubrations of the above-mentioned gentlemen. As a lover of truth, I am willing to face a thousand reproaches. Be it distinctly understood that I do not for a moment deem my judgment superior to that of my confrères, some of whom are in other respects highly gifted. The simple fact is that they are not familiar with this subject, but are straying in it at random, wandering through a strange region. They misunderstand the very terminology, and imagine that facts long ago well authenticated are impossible. By way of contrast, the writer of these lines will state that for several years he has been engaged in discussions and experiments upon the subject. (I am not speaking of historical studies.)

"Moreover, although the old saw would have us believe that 'it is not always desirable to state the truth,' yet, to speak frankly, I am so indignant at the overweening presumption of certain polemical opponents, and at the gall they have injected into the debate, that I do not hesitate to rise and point out to the deceived public that, without a single exception, all the arguments brought up by these writers, and upon which they have boldly planted their banner of victory, prove absolutely nothing, NOTHING, against the possible truth of the things which they, in the fury of their denial, have so perverted. Such a snarl of opinions must be analyzed. In brief, the true must be disentangled from the false. Veritas, veritas!"
