CHAPTER III

RELATION OF MIND ACTIVITY TO BODILY ACTIVITY

POINT OF VIEW FROM WHICH YOU MUST APPROACH THIS PROBLEM

[Sidenote: Speculation and Practical Science]

The fact is, one's opinion as to whether mind controls body or body

makes mind-action depends altogether upon the point of view. And the

first step for us to take is to agree upon the point of view we shall

assume.

Two points of view are possible. One is _speculative_, the other

_practical_.

[Sidenote: Philosophic Riddles and Personal Effectiveness]

The _speculative point of view_ is that of the philosopher and

religionist, who ponder the tie that binds "soul" and body in an effort

to solve the riddle of "creation" and pierce the mystery of the

"hereafter."

The _practical point of view_ is that of the modern practical scientist,

who deals only with actual facts of human experience and seeks only

immediate practical results.

The speculative problem is the historical and religious one of the

mortality or immortality of the soul. The practical problem is the

scientific one that demands to know what the mental forces are and how

they can be used most effectively.

[Sidenote: What We Want to Know]

There is no especial need here to trace the historical development of

these two problems or enter upon a discussion of religious or

philosophical questions.

Our immediate interest in the mind and its relationship to the body is

not because we want to be assured of the salvation of our souls after

death.

_We want to know all we can about the reality and certainty and

character of mental control of bodily functions because of the practical

use we can make of such knowledge in this life, here and now._

[Sidenote: Spiritualist, Materialist and Scientist]

The practical scientist has nothing in common with either spiritualists,

soul-believers, on the one hand, or materialists on the other. So far as

the mortality of the soul is concerned, he may be either a spiritualist

or a materialist But spiritualism or materialism is to him only an

intellectual pastime. It is not his trade. In his actual work he seeks

only practical results, and so confines himself wholly to the actual

facts of human experience.

The practical scientist knows that as between two given facts, and

_only_ as between these two, one may be the "cause" of the other. But he

is not interested in the "creative origin" of material things. He does

not attempt to discover "first" causes.

[Sidenote: Science of Cause and Effect]

The practical scientist ascribes all sorts of qualities to electricity

and lays down many laws concerning it without having the remotest idea

as to what, in the last analysis, electricity may actually be. He is not

concerned with ultimate truths. He does his work, and necessarily so,

upon the principle that for all practical purposes he is justified in

using any given assumption as a working hypothesis if everything happens

just as if it were true.

The practical scientist applies the term "cause" to any object or event

that is the invariable predecessor of some other object or event.

For him a "cause" is simply any object or event that may be looked upon

as forecasting the action of some other object or the occurrence of some

other event.

The point with him is simply this, Does or does not this object or this

event in any way affect that object or that event or determine its

behavior?

[Sidenote: Causes and "First" Causes]

No matter where you look you will find that every fact in Nature is

relatively cause and effect according to the point of view. Thus, if a

railroad engine backs into a train of cars it transmits a certain amount

of motion to the first car. This imparted motion is again passed on to

the next car, and so on. The motion of the first car is, on the one

hand, the effect of the impact of the engine, and is, on the other hand,

the "cause" of the motion of the second car. And, in general, what is an

"effect" in the first car becomes a "cause" when looked at in relation

to the second, and what is an "effect" in the second becomes a "cause"

in relation to the third. So that even the materialist will agree that

"cause" and "effect" are relative terms in dealing with any series of

facts in Nature.

[Sidenote: A Common Platform for All]

A man may be either a spiritualist, believing that the mind is a

manifestation of the super-soul, or he may be a materialist, and in

either case he may at the same time and with perfect consistency

believe, as a practical scientist, that the mind is a "cause" and has

bodily action as its "effect."

Naturally this point of view offers no difficulties whatever to the

spiritualist. He already looks upon the mind or soul as the "originating

cause" of everything.

[Sidenote: Thoughts Treated as Causes]

But the materialist, too, may in accordance with his speculative theory

continue to insist that _brain-action_ is the "originating cause" of

mental life; yet if the facts show that certain thoughts are invariably

followed by certain bodily activities, the materialist may without

violence to his theories agree to the great practical value of _treating

these thoughts as immediate causes_, no matter what the history of

creation may have been.

Whatever the brand of your materialism or your religious belief, you

can join us in accepting this practical-science point of view as a

common platform upon which to approach our second fundamental

proposition, that "all bodily activity is caused, controlled and

directed by the mind."

[Sidenote: Scientific Method with Practical Problems]

Ignoring all religious and metaphysical questions, we have, then, to ask

ourselves merely: _Can the mind be relied upon to bring about or stop or

in any manner influence bodily action? And if it can, what is the extent

of the mind's influence?_

In answering these questions we shall follow the method of the practical

scientist, whose method is invariably the same whatever the problem he

is investigating.

This method involves two steps: first, the collection and classification

of facts; second, the deduction from those facts of general principles.

[Sidenote: Uses of Scientific Laws]

The scientist first gathers together the greatest possible array of

experiential facts and classifies these facts into sequences--that is to

say, he gathers together as many instances as he can find in which one

given fact follows directly upon the happening of another given fact.

Having done this, he next formulates in broad general terms the common

principle that he finds embodied in these many similar sequences.

Such a formula, if there are facts enough to establish it, is what is

known as a scientific law. Its value to the world lies in this, that

whenever the given fact shall again occur our knowledge of the

scientific law will enable us to predict with certainty just what events

will follow the occurrence of that fact.

First, then, let us marshal our facts tending to prove that bodily

activities are caused by the mind.
