CHAPTER XVII

DISSOCIATION

While the device of repression may adequately deal with many of the

unwelcome thoughts that intrude themselves upon us, it is not capable

of doing so in every case, and then the process is carried a stage

further, and DISSOCIATION takes place.

Dissociation is pathological forgetting. Emotion is the life of an

idea. In ordinary forgetting a memory sinks into the subconscious

because insufficient interest is attached to it to enable it to remain

in consciousness; if, however, an idea associated with some strong

emotion is repressed into the subconscious, that emotion will, as it

were, vivify it, and cause it to have an independent life of its own;

it splits off from the personality and is said to be dissociated.

It will be noted that in our study of memory we saw that ideas never

remain solitary, but tend to form associations among themselves, or,

as they are technically termed, complexes. The dissociated idea is

no exception to this rule; not only does it form alliances with its

fellow prisoners, but its chains of associations manage to evade

the censor and ramify through the other levels of the mind with

far-reaching consequences, giving rise to much of the illogicality and

unreasonableness which disturb our attempts at rational thinking.

We have already noted that a complex is a group of ideas held together

by some emotionally toned interest; and as all emotion has its root

in an instinct, it follows that all complexes must be affiliated to

one or other of the instincts; as they sink into the subconscious they

therefore go down the channel of the instinct to which they belong, and

as they are swimming against the current they tend to block the flow of

that particular instinct and to cause it to express itself through the

subsidiary channel which they are endeavouring to open up.

It can readily be seen that serious consequences must arise from an

obstacle lodged in the fairway of so great a force and drawing to

itself, under the law of association of ideas, all thoughts that may

enter the mind on the same subject, or that have a real or symbolic

resemblance to it. As has been truly said, the subconscious grows at

the expense of the conscious, and the balance of the mind is upset;

the thrust of life, the source of all energy, instead of flowing

freely from level to level, is blocked by the complex and held up

in the subconscious, causing the pressure on that level to rise to

danger-point, while the conscious mind is sapped of its vitality,

producing an individual of imperative and chaotic needs, which he is

unable to formulate, even to himself, and with no power to give them

expression or obtain their satisfaction.
