While he was maintaining this ground, Spiritualists often asked him how he explained the intelligence that was manifested; and he invariably replied that he had not yet seen proofs of any intelligence other than what might be that of the medium or of some other persons present in the circle, adding, that as soon as he did see proofs of such intelligence he should become a Spiritualist. In this position he stood for many years, till he naturally believed he should never see cause to change his opinion. He continued the inquiry, however, and in 1865 began to hold séances at home; but it was years before any mental phenomena occurred which were absolutely conclusive, although they were often of so startling a nature as would have satisfied any one less skeptical. At length, after fifteen years of enlightened skepticism—a skepticism not founded upon ignorance, but which refused to go one step beyond what the facts so diligently pursued absolutely demonstrated—the needful evidence came: “The proofs that I did ultimately receive are, many of them, of a character that I cannot describe minutely to a public audience, nor indeed have I time to do so. Suffice it to say, that I got in my own house, in the absence of all mediums other than those members of my own family and intimate private friends in whom mediumistic powers became developed, evidence of an irresistible character that the communications came from deceased friends and relatives. Intelligence was again and again displayed which could not possibly have had any other origin than that which it professed to have. Facts were named known to no one in the circle, and left to be verified afterwards. The identity of the spirits communicating was proved in a hundred different ways. Our dear departed ones made themselves palpable both to feeling and to sight; and the doctrine of spirit-communion was proved beyond the shadow of a doubt. I soon found myself in the position of Dr. Fenwick in Lord Lytton’s ‘Strange Story.’ ‘Do you believe,’ asked the female attendant of Margrave, ‘in that which you seek?’ ‘I have no belief,’ was the answer. ‘True science has none; true science questions all things, and takes nothing on credit. It knows but three states of mind—denial, conviction, and the vast interval between the two, which is not belief, but the suspension of judgment.’ This describes exactly the phases through which my mind has passed.”
