man's soul and a living man's body? If not, why not? Why should a dead man's spirit in abnormal union with a living man's body possess more power than a living man's spirit in normal union with his own body? Is it because the former possesses more knowledge than the latter ? No, for we have seen that it is only " inferior spirits " who are capable of producing physical manifestations. Superior knowledge confers no advantage ; for, as Kardec informs us, the superior spirits have no power in that direction. We have, therefore, the authority of the spiritists themselves for formulating the proposition that the more completely the spirit of a man is " disengaged from material influence," the less power he possesses to produce physical phenomena. This being true, it follows that the converse of the proposition is true, namely, that the more completely the spirit of a man is united to material elements, the greater is his power to produce such phenomena. The conclusion is irresistible that the spirit of a man in normal union with his own body possesses the power in perfection.
If, therefore, we can find in abstract reasoning no warrant for the assumption that the phenomena are produced by disembodied spirits, we must look elsewhere for evidence of their extramundane origin. The first inquiry naturally suggesting itself is, What internal evidence is contained in the character of the manifestations which would enable one to form a correct judgment regarding their probable source ? We have already seen that reasoning from their physical character leads us to the conclusion that the physical power displayed must have a physical basis, and that that basis is probably the physical organism of the medium. Now, if its intellectual character leads us in the same direction, the evidence is still stronger in favor of its purely human origin. We presume that no one will dispute the proposition that the communications received through the physical phenomena are governed by the same laws as those received by means of the other methods which have been discussed. Indeed, the fact is almost self-evident. They have the Same origin, and must be governed by the same laws. The
