"I don't see it that way," rejoined Fowler, calmly. "Suppose your biologists prove that the psychic can put forth a supernumerary arm, or maintain, for a short time, a complete double of herself. Would that necessarily make the spiritist theory untenable? Is it not fair to conclude that if the soul or 'astral' or 'etheric double' can act outside the living body, it can live and think and manifest after the dissolution of its material shell? Does not the experimental work of Bottazzi, Morselli, and De Rochas all make for a spiritual interpretation of life rather than for the position of the materialist? I consider that they have strengthened rather than weakened the mystic side of the universe. They are bringing the wonder of the world back to the positivist. Let them go on. They will yet demonstrate, in spite of themselves, the immortality of the soul." "I hope they will," I replied. "It would be glorious at this time, when tradition begins to fail of power, to have a demonstration of immortality come through the methods of experimental science. Certainly I would welcome a physical proof that my mother still thinks and lives, and that Ernest and other of my dearest friends are at work on other planes and surrounded by other conditions, no matter how different from the conventional idea of paradise these environments might be; but the proof must be ample and very definite." Miller put in a last word of warning: "Because a phenomenon has not been explained, and no one knows how to explain it, is no reason for supposing there is anything extraphysical about it. No one has explained the first cause of the development of an embryo. No one knows what goes on in an active nerve, or why atoms are selective in their associates. Ignorance is not a proper basis for speculation, and if one must have a theory, let it be one having some obvious continuity with our best physical knowledge." And at that point our argument rested. We separated, and each went his way, to be met by questions of business and politics, and to be once more blended to the all-enveloping mystery of life. FOOTNOTE: [2] Since this conversation I have had a letter from another well-authenticated psychic, a man making his living by honest labor as a carpenter, who gives very definitely his experience on emitting an etheric double. He says: "One evening, while sitting at the table, I began to feel as if I were swelling up. My thumb felt as big as my arm, and my arm as big as my leg. While I was perfectly aware that I was at the dinner-table, I also felt myself in the hall trying to enter the dining-room. I found the knob, I opened the door. The others saw me traverse the room toward myself. My dual body came close beside me and vanished with a snap."
