"Again, why should not the brain, or the nervous system, or whatever controls the sensuous processes of man, be able, when artificially excited, stimulated, exalted--as by mesmerism or somnambulism--to see, hear, and feel for itself; see, without eyes; hear, without ears; feel, without fingers? In other words--Why should it not be capable of clairvoyance and clairaudience? I assert that it does, and many in this room will support my assertion. A learned physician and devout Catholic--Dr. F. Lefebre, Professor of Pathology at highly orthodox Louvain--goes so far as to affirm 'it is possible that the somnambulists' power of foresight may be raised to a degree far above the ordinary level, and that they can sometimes penetrate into the future so far as to excite our utmost astonishment.' In fact, this honest and courageous scientist confesses his belief in 'second sight.' Thus the heterodoxies of yesterday become the orthodoxies of to-day. That sturdy incarnation of common sense, Dr. Johnson, the Philistine Colossus of English literature, would certainly, had Spiritualism been developed in his day, have become a thorough-paced Spiritualist. The theory of extra-sensuous perception of things sensuous is to be proved or disproved, not by hard words, not by mere logic, but by experiment and facts. Meanwhile I hold myself justified in believing it to be true, and others equally justified in believing it to be false. As the wise man said, 'Different people have different opinions.' And in our present transitional empirical state of knowledge unanimity appears hopeless. Half the world of Christendom believes that 'miracles' still take place; the other half denies their taking place: and who shall decide between them?
