"How do you account for it? It was an illusion, of course. You thought the illusion only ocular--it extended to the sense of touch." Weissmann's eyes gleamed speculatively. "We will let it go so. The world of sense and the world of spirit curiously intermingle--as we know." "But these manifestations, so far as I have any knowledge, are so foolish and childish--" "Well, so many foolish and childish persons have gone to the other world. Death is not the beginning of wisdom. I am an old man, Serviss, and already many of my loved ones are dead. I should like to believe they are still sentient, and maybe they are. I am German. The blood of Kant is in my veins." He seemed to be speaking partly to himself. "I do not dogmatize so gladly as I once did. As I do not know the essence of matter, it would be folly for me to assume to fathom the depth of spirit. The essential hopelessness of science is coming to render me humble. Spiritualism certainly is a comfortable belief. I would gladly embrace it if I could. I suspend judgment. This desire for another life may be only a survival of a more unreasoning time, something we will outgrow." Serviss was profoundly surprised by his chief's attitude. He had expected a large, calm, and rather contemptuous reply to his question. In place of decision he encountered a doubt, a hesitancy, which betrayed weakness. Rudolph Weissmann, great as he was, belonged to the innumerable throng of the bereaved whose judgments are clouded by passion. He, too, was growing old, his all-embracing mind had yielded to an hallucination. The young man's respect for his chief did not diminish, but a feeling of sadness swept over him as he realized that another renowned and fearless investigator was nearing the end of his great usefulness, and that upon the clear blue steel of his intelligence the rust of age had begun to fall. Truly the power of his early training, his worship of Kant and his school was still vital. Then he pondered his words. "If I were a young man like you I would investigate this thing," and recalled that no young man of science had ever devoted himself to it. "They all came to it late in life, after bereavement."
