The opposing power alone of unbelief and skepticism, if projected in a current of equal force, can check the other, and sometimes completely neutralize it. Why should spiritualists wonder that the presence of some strong skeptics, or of those who, feeling bitterly opposed to the phenomenon, unconsciously exercise their will-power in opposition, hinders and often stops altogether the manifestations? If there is no _conscious_ power on earth but sometimes finds another to interfere with or even counterbalance it, why wonder when the _unconscious_, passive power of a medium is suddenly paralyzed in its effects by another opposing one, though it also be as unconsciously exercised? Professors Faraday and Tyndall boasted that their presence at a circle would stop at once every manifestation. This fact alone ought to have proved to the eminent scientists that there was some force in these phenomena worthy to arrest their attention. As a scientist, Prof. Tyndall was perhaps pre-eminent in the circle of those who were present at the seance; as a shrewd observer, one not easily deceived by a tricking medium, he was perhaps no better, if as clever, as others in the room, and if the manifestations were but a fraud so ingenious as to deceive the others, they would not have stopped, even on _his_ account. What medium can ever boast of such phenomena as were produced by Jesus, and the apostle Paul after him? Yet even Jesus met with cases where the unconscious force of resistance overpowered even his so well directed current of will. “And he did not many mighty works there, because of their unbelief.” There is a reflection of every one of these views in Schopenhauer’s philosophy. Our “investigating” scientists might consult his works with profit. They will find therein many a strange hypothesis founded on old ideas, speculations on the “new” phenomena, which may prove as reasonable as any, and be saved the useless trouble of inventing {58} new theories. The psychic and ectenic forces, the “ideo-motor” and “electro-biological powers;” “latent thought” and even “unconscious cerebration” theories, can be condensed in two words: the kabalistic ASTRAL LIGHT.
