A great fact this, even when standing alone; but
add to it the test of your subtle electrical stimulus,
and you find that all that is implied in the distinction
between influential and automatic is borne out by
these two colossal circumstances, -· that stimulus on
the influential arcs will produce no motion, but that
it does produce complex motion if applied to the
automatic arcs; and that half of the brain may be
taken away, paralyzing the half of your body, while
the mind continues all its operations. [Applause.]
10. Physiological causes do not act where they do
11. The action of the influential nervous mechan-
ism is not, therefore, originated by the physical causes
operating in the automatic nervous mechanism.
12. But the inertness of the mechanism in itself
demonstrates that it must be set in motion by an
external agent. ..
13. That·agent. must be either matter or mind.
14. It is demonstrated that the action of the bio-
plasts in weaving the brain, and that of the frontal
lobes after they are woven, cannot originate in mat-
15. It originates, therefore, in an external _ imma-
16. This, which is, in part, immediately known to
consciousness, is life and the soul.
17. ~1odern microscopical research, therefore,
proves that the soul is an agent external to the· nerv·
ous mechanism which it sets in motion.
