What can we reasonably consider to be the content of the unconscious in the case of such an individual?

Considered from the above theoretical standpoint, everything in the personality that is not contained in the conscious mind should be found in the unconscious. Let us agree, then, that this man consciously considers himself to possess all the fine attributes we have just described—no more, no less. Then it must obviously result that he is entirely unaware that a man may be not merely industrious, thorough, and painstaking, but that he may also be careless, indifferent, untrustworthy; for some of these last attributes are the common heritage of mankind and may be found to be an essential component of every character. This worthy merchant forgets that quite recently he allowed several letters to remain unanswered which he could easily have answered at once. He forgets, too, that he failed to bring a book home which his wife has asked him to get at the book-stall, where she had previously ordered it, although he might easily have made a note of her wish. But such occurrences are common with him. Therefore we are obliged to conclude that he is also lazy and untrustworthy. He is convinced that he is a thoroughly loyal subject; but for all that he failed to declare the whole of his income to the assessor, and when they raise his taxes, he votes for the Socialists.

He believes himself to be an independent thinker, yet a little while back he undertook a big deal on the Stock Exchange, and when he came to enter the details of the transaction in his books he noticed with considerable misgivings that it fell upon a Friday, the 13th of the month. Therefore, he is also superstitious and not free in his thinking.

So here we are not at all surprised to find these compensating vices to be an essential content of the unconscious. Obviously, therefore, the reverse is true—namely, that unconscious virtues compensate for conscious deficiencies. The law which ought to follow as the result of such deductions would appear to be quite simple—to wit, the conscious spendthrift is unconsciously a miser; the philanthropist is unconsciously an egoist and misanthrope. But, unfortunately, it is not quite so easy as that, although there is a basis of truth in this simple rule. For there are essential hereditary dispositions of a latent or manifest nature which upset the simple rule of compensation, and which vary greatly in individual cases. From entirely different motives a man may, for instance, be a philanthropist, but the manner of his philanthropy depends upon his originally inherited disposition, and the way in which the philanthropic attitude is compensated depends upon his motives. It is not sufficient simply to know that a certain person is philanthropic in order to diagnose an unconscious egoism. For we must also bring to such a diagnosis a careful study of the motives involved.

In the case of normal people the principal function of the unconscious is to effect a compensation and thus produce a balance. All extreme conscious tendencies are softened and toned down through an effective opposite impulse in the unconscious. This compensating agency, as I have tried to show in the case of the merchant, maintains itself through certain unconscious, inconsequent activities, as it were, which Freud has very well described as symptomatic acts (Symptom-handlungen).

To Freud we owe thanks also for having called attention to the importance of dreams, for by means of them, also, we are able to learn much about this compensating function. There is a fine historical example of this in the well-known dream of Nebuchadnezzar in the fourth chapter of the Book of Daniel, where Nebuchadnezzar at the height of his power had a dream which foretold his downfall. He dreamed of a tree which had raised its head even up to heaven and now must be hewn down. This is a dream which is obviously a counterpoise to the exaggerated feeling of royal power.

Now considering states in which the mental balance is disturbed, we can easily see, from what has preceded, wherein lies the importance of the unconscious for psychopathology. Let us ponder the question of where and in what manner the unconscious manifests itself in abnormal mental conditions. The way in which the unconscious works is most clearly seen in disturbances of a psychogenic nature, such as hysteria, compulsion neurosis, etc.

We have known for a long time that certain symptoms of these disturbances are produced by unconscious psychic events. Just as clear, but less recognised, are the manifestations of the unconscious in actually insane patients. As the intuitive ideas of normal men do not spring from logical combinations of the conscious mind, so the hallucinations and delusions of the insane arise, not out of conscious but out of unconscious processes.

Formerly, when we held a more materialistic view of psychiatry we were inclined to believe that all delusions, hallucinations, stereotypic acts, etc., were provoked by morbid processes in the brain cells. Such a theory, however, ignores that delusions, hallucinations, etc., are also to be met with in certain functional disturbances, and not only in the case of functional disturbances, but also in the case of normal people. Primitive people may have visions and hear strange voices without having their mental processes at all disturbed. To seek to ascribe symptoms of that nature directly to a disease of the brain cells I hold to be superficial and unwarranted. Hallucinations show very plainly how a part of the unconscious content can force itself across the threshold of the conscious. The same is true of a delusion whose appearance is at once strange and unexpected by the patient.

The expression "mental balance" is no mere figure of speech, for its disturbance is a real disturbance of that equilibrium which actually exists between the unconscious and conscious content to a greater extent than has heretofore been recognised or understood. As a matter of fact, it amounts to this—that the normal functioning of the unconscious processes breaks through into the conscious mind in an abnormal manner, and thereby disturbs the adaptation of the individual to his environment.
