CHAPTER II

STAGES OF FEAR

The fear instinct in its course of development passes through three

stages:

I. The Stimulating Stage

II. The Arrestive, or Inhibitory Stage

III. The Paralyzing Stage.

In its milder forms when the fear instinct is but nascent, it

serves as a sort of trigger to the activities of the organism.

The animal may for a moment stop whatever activities and pursuits

in which it happens to be engaged, and have its interest turn in

the direction of the particular new stimulus, whether it be of an

auditory, visual, or olfactory character. The fear instinct is

just strong enough to suspend present interests, and direct its

activities to the new source of the unknown stimulus.

When the source is unfamiliar, the animal becomes prepared for

action. The energies are aroused for attack, or for hiding,

freezing, or running, according to the mode of defense to which the

animal has been adapted in its adjustments to the stimulations of

its environment. The lion, the tiger, the skunk, the snake, the

bird, the rabbit, the squirrel will act differently, according

to their natural disposition in response to external objects and

stimuli.

While the motor system may react differently in various animals,

the fear instinct is alike in all of them. This stage of the fear

instinct should be regarded as the healthy physiological reaction

to strange and new stimuli, and is essentially protective, inasmuch

as it serves for the arousal of energy and proper reactions of

self-defense, characteristic of the particular individual.

In its milder forms the fear instinct is _normal_, _physiological_,

and healthy in its reactions. In fact, the absence of it is rather

pathological. It is quite natural that under the influence of some

danger, the organism may feel the urging of this vital instinct,

the consequent of the fundamental life impulse, and feel it as a

stimulus rather than as a deterrent experience, feel fear as the

key for the unlocking of energies in defense or attack. Such a

reaction is healthy and strictly requisite in the total economy of

life.

When I advanced the theory that the fear instinct is at the bottom

of functional psychosis, or of psychopathic maladies, some jumped

to the conclusion that I regarded the fear instinct as abnormal,

giving rise to pathological states under all conditions and

circumstances. This is not correct. _The fear instinct in its

initial stages is perfectly normal, and is as indispensable to life

as hunger and thirst._ It is only in the more advanced and extreme

stages that the fear instinct becomes pathological, and is apt to

give rise to psychopathic states.

In the arrestive or inhibitory state, the innervation of the

voluntary and the involuntary muscular systems is arrested, or

weakened. There is tremor and even convulsive contractions,

the voluntary reactions are affected, and are carried out with

some difficulty; there is cardiac arrhythmia, the respiration

is irregular; there may be chattering of the teeth; the various

bodily secretions are interfered with, and the vaso-motor nerves

as well as the general vascular structures are thrown into

disorder. Peristalsis, intestinal secretions, and the innervation

of the sympathetic nervous system may become affected, first

by inhibition, and then by irregular functioning. Associative

mental or cerebral activity becomes arrested, confused; memory is

disturbed, and the whole personality or individuality appears in a

state of dissociation, accompanied by a lack of precision and lack

of exactness of neuromuscular adaptations. The delicate reactions

and adaptations are specially affected.

If this stage of fear instinct does not become intensified, the

organism recovers its control,--many of the disturbances pass

away, and the following reaction may come with a greater release

of energy, developing a greater output of activity than under

normal conditions. In short, the fear instinct may still serve as

a stimulation to greater effort, but the chances of such a result

are far smaller than in the first stage, which is essentially of a

stimulating, useful, and healthful character.

The second stage of the fear instinct is the possibility of a

pathological state, and, if persistent, leads directly to the third

stage with consequent paralysis and danger of destruction. The

first stage of fear is fully normal, helpful, and self-defensive.

The second stage is harmful, but with the possibility of recovery

and restitution of normal function. The third stage leads to

destruction and death.

In the third stage there is paralysis of function of most of the

muscular, secretory, excretory, circulatory, intestinal, and

nervous systems. The animal is petrified with fear, and falls

into a state of paralysis, rigidity, cataplexy, or in a state

simulating death. This last stage of the effects of the fear

instinct is pathological, and instead of conducing to the good of

the individual, really leads to his destruction and death. The fear

instinct in its extreme cases is not a help to the organism, but is

distinctly a hindrance, and is felt as such by the organism which

experiences it.

The fear instinct, which originally is a stimulating agent for

self-defense, when in excess becomes a danger hastening the

dissolution of the animal organism into its constituent parts.

The intensity of the fear instinct is the expression of the fact

that the organism is in imminent danger of destruction. The fear

instinct in its extreme state is decidedly to the disadvantage of

the animal.

Of course, it may be claimed that the paralysis and inhibition

stages might have been of service or of protective value in the

lower forms of life, when mimicking death or freezing prevented

the animal from being noticed. This may possibly hold true in the

cases of lower forms, but in the higher forms the fear instinct in

its third stage, by bringing about inhibitions and paralysis of the

vital functions, is decidedly of disservice to the organism, and

leads to its destruction and death.
