bring them about; they cease when that effort is discontinued; they abound
in indications of being produced by independent intelligencies; they are
inexplicable upon any recognized theory of physics; and, therefore, there
is nothing for it but to regard them as spiritual. And what then? Then, of
course, there must be spirits, and a life after the death of the body; and
the great question of Immortality is answered in the affirmative!

Let us, for the sake of argument, concede that the manifestations upon
which the Spiritists found their claims are genuine: that they are or can
be produced without fraud; and let us then enquire in what respect our
means for the conversion of the sceptic are improved. In the first place
we find that all the manifestations--be their cause what it may--can occur
only on the physical plane. However much the origin of the phenomena may
perplex us, the phenomena themselves must be purely material, in so far as
they are perceptible at all. "Raps" are audible according to the same laws
of vibration as other sounds: the tilting table is simply a material body
displaced by an adequate agency; the materialized hand or face is nothing
but physical substance assuming form. Plainly, therefore, we have as much
right to ascribe a spiritual source to such phenomena as we have to
ascribe a spiritual source to the ordinary phenomena of nature, such as a
tree or a man's body,--just as much right--and no more! Consequently, we
are no nearer converting our sceptic than we were at the outset. He admits
the physical manifestation: there is no intrinsic novelty about that: but
when we proceed to argue that the manifestations are wrought by spirits,
he points out to us that this is sheer assumption on our part. "I have not
seen a spirit," he says: "I have not heard one; I have not felt one; nor
is it possible that my bodily senses should perceive anything that is not
at least as physical as they are. I have witnessed certain transactions
effected by means unknown to me--possibly by the action of a natural law
not yet fully expounded by science. If there was anything spiritual in the
