_Reader._ If these gentlemen could by no means be convinced of the deception, must we not presume that there was no deception, and that your peculiar construction of the case was brought about by a strong desire of not being disturbed in your fixed idea that there is nothing but matter? If “the lady failed in all her indications,” if “she made the most ridiculous excuses for her shortcomings,” if “she manifested no superior capacities,” it should have been evident to those “several gentlemen” that she was a fraud. Their inability to be convinced of the deception would therefore show that the lady did not fail in all her indications, but manifested superior capacities. Be this as it may, the truth and reality of spiritual manifestations cannot be disproved by particular attempts at imposition. Spiritualists admit that many impositions have been practised under the name of spiritual manifestations, but they aver that in most instances cheats could not have been palmed off, even if designed; and that in other cases there could be no possible motive for deception, as the investigations were carried on in private families where the mediums were their own sons and daughters.(50) Spirit‐rapping is a fact. Table‐ turning is a fact. Clairvoyance is a fact. Thousands of all conditions, sects, and nations have witnessed, watched, and examined all such facts with a degree of attention, suspicion, and incredulity proportionate to their novelty, strangeness, and unnaturalness. What has been the result? A verdict acknowledging the reality of the facts and the impossibility of accounting for them without intelligent preternatural agencies. This verdict disposes of your materialism. To deny the facts in order to save materialism is so much time lost. Facts speak for themselves. XVI. Innate Ideas _Reader._ And now I should like to know, doctor, why you thought proper to fill twenty‐seven pages of your _Force and Matter_ with a discussion about innate ideas.
