Section 48. (c) The Subconscious.

It is my opinion that the importance of unconscious operations[208] in

legal procedure is undervalued. We could establish much that is

significant concerning an individual whose unconscious doings we knew.

For, as a rule, we perform unconsciously things that are deeply

habitual, therefore, first of all what everybody does--walk, greet your

neighbor, dodge, eat, etc.; secondly, we perform unconsciously things to

which we have become accustomed in accordance with our especial

characters.[209] When, during my work, I rise, get a glass of water,

drink it, and set the glass aside again, without having the slightest

suspicion of having done so, I must agree that this was possible only in

my well-known residence and environment, and that it was possible to

nobody else, not so familiar. The coachman, perhaps, puts the horses

into the stable, rubs them down, etc., and thinks of something else

while doing so. He has performed unconsciously what another could not.

It might happen that I roll a cigarette while I am working, and put it

aside; after awhile I roll a second and a third, and sometimes I have

four cigarettes side by side. I needed to smoke, had prepared a

cigarette, and simply because I had to use my hands in writing, etc., I

laid the cigarette aside. In consequence, the need to smoke was not

satisfied and the process was repeated. This indicates what complicated

things may be unconsciously performed if only the conditions are

well-known; but it also indicates what the limits of unconscious action

are: e.g., I had not forgotten what would satisfy my need to smoke, nor

where my cigarette paper was, nor how to make a cigarette, but I had

forgotten that I had made a cigarette without having smoked it. The

activities first named have been repeated thousands of times, while the

last had only just been performed and therefore had not become

mechanical.[210]

Lipps calls attention to another instance: “It may be that I am capable

of retaining every word of a speech and of observing at the same time

the expression which accompanies the speech. I might be equally able to

trace a noise which occurs on the street and still to pay sufficient

attention to the speech. On the other hand, I should lose the thread of

the speech if I were required at the same time to think of the play of

feature and the noise. Expressed in general terms, idea A may possibly

get on with idea B and even idea C; but B and C together make A

impossible. This clearly indicates that B and C in themselves have

opposed A and inhibited it in some degree, but that only the summation

of their inhibition could serve really to exclude A.” This is certainly

correct and may perhaps be more frequently made use of when it is

necessary to judge how much an individual would have done at one and

the same time, and how much he would have done unconsciously. An

approximation of the possibilities can always be made.

Such complicated processes go down to the simplest operations. Aubert

indicates, for example, that in riding a horse at gallop you jump and

only later observe whether you have jumped to the right or the left. And

the physician Förster told Aubert that his patients often did not know

how to look toward right or left. At the same time, everybody remembers

how when he is doing it unconsciously, and it may often be observed that

people have to make the sign of the cross, or the gesture of eating in

order to discover what is right and what left, although they are

unconsciously quite certain of these directions. Still broader

activities are bound up with this unconscious psychosis, activities for

us of importance when the accused later give us different and better

explanations than at the beginning, and when they have not had the

opportunity to study the case out and make additional discoveries, or to

think it over in the mean time. They then say honestly that the new,

really probable exposition has suddenly occurred to them. As a rule we

do not believe such statements, and we are wrong, for even when this

sudden vision appears improbable and not easily realizable, the

witnesses have explained it in this way only because they do not know

the psychological process, which, as a matter of fact, consisted of

subconscious thinking.

The brain does not merely receive impressions unconsciously, it

registers them without the co-operation of consciousness, works them

over unconsciously, awakens the latent residua without the help of

consciousness, and reacts like an organ endowed with organic life toward

the inner stimuli which it receives from other parts of the body. That

this also influences the activity of the imagination, Goethe has

indicated in his statement to Schiller: “Impressions must work silently

in me for a very long time before they show themselves willing to be

used poetically.”

In other respects everybody knows something about this unconscious

intellectual activity. Frequently we plague ourselves with the attempt

to bring order into the flow of ideas--and we fail. Then the next time,

without our having thought of the matter in the interval, we find

everything smooth and clear. It is on this fact that the various popular

maxims rest, e.g., to think a thing over, or to sleep on it, etc. The

unconscious activity of thought has a great share in what has been

thought out.

A very distinctive rôle belongs to the coincidence of conscious

attention with unconscious. An explanation of this process will help us,

perhaps, to explain many incomprehensible and improbable things. “Even

the unconscious psychic activities,--going up and down, smoking, playing

with the hands, etc., conversation,--compete with the conscious or with

other unconscious activities for psychic energy. Hence, a

suddenly-appearing important idea may lead us to stop walking, to remain

without a rule of action, may make the smoker drop his smoking, etc.”

The explanation is as follows: I possess, let us say, 100 units of

psychic energy which I might use in attention. Now we find it difficult

to attend for twenty seconds to one point, and more so to direct our

thought-energy to one thing. Hence I apply only, let us say, 90 units to

the object in question, and apply 10 units to the unconscious play of

ideas, etc. Now, if the first object suddenly demands even more

attention, it draws off the other ten units, and I must stop playing,

for absolutely without attention, even unconscious attention, nothing

can be done.

This very frequent and well-known phenomenon, shows us, first of all,

the unconscious activities in their agreement with the conscious,

inasmuch as we behave in the same way when both are interrupted by the

demand of another thing on our attention. If a row suddenly breaks out

before my window I will interrupt an unconscious drumming with the

fingers as well as a conscious reading, so that it would be impossible

to draw any conclusion concerning the nature of these activities from

the mere interruption or the manner of that interruption. This

similarity is an additional ground for the fact that what is done

unconsciously may be very complex. No absolute boundary may be drawn,

and hence we can derive no proof of the incorrectness of an assertion

from the performance itself, i.e., from _what_ has been done

unconsciously. Only human nature, its habits, idiosyncrasies, and its

contemporary environment can give us any norm.
