Those who practise it know nothing of its _modus operandi_, any more than
the bird that sings on yonder willow knows of the science of music.
To the common suggestion, "It's spirits," I say, No, _no_!
If it were "spirits," why does the spirit always seek a _low organization_
through which to manifest itself? There are few exceptions to this rule.
It is unnatural, inconsistent with the divine attributes for the
supernatural to mingle with the natural. The circulation of the blood was
once attributed to the action of the sun--hence a man fell asleep at
sunset--and to supernatural causes.
Science has done away with these absurd notions.
"It is a manifestation of divine power," say others.
Well, for that matter, everything is; but _directly_ it is not, for what
answers the "spirit" suggestion answers this one also. Divine power cannot
be limited.
