The man of a generation back of the present one would have been equally
justified in asserting that the marvels of wireless telegraphy were
supernatural, had he been told of the possibility of their manifestation.
Going back a little further, the father of that man would have said the
same thing regarding the telephone, had anyone been so bold as to have
prophesied it. Going back still another generation, imagine the opinion of
some of the old men of that time regarding the telegraph. And yet these
things are simply the discovery and application of certain of Nature's
wonderful powers and forces.

Is it any more unreasonable to suppose that Nature has still a mine of
undiscovered treasure in the mind and constitution of man, as well as in
inorganic nature? No, friends, these things are as natural as the physical
senses, and not a whit more of a miracle. It is only that we are
accustomed to one, and not to the other, that makes the astral senses seem
more wonderful than the physical. Nature's workings are all
