Our “increasing mental sickness” may find expression in neurotic symptoms. These symptoms are conspicuous and extremely distressing. But “let us beware,” says Dr. Fromm, “of defining mental hygiene as the prevention of symptoms. Symptoms as such are not our enemy, but our friend, where there are symptoms there is conflict, and conflict always indicates that the forces of life which strive for integration and happiness are still fighting.” The really hopeless victims of mental illness are to be found among those who appear to be most normal. “Many of them are normal because they are so well adjusted to our mode of existence, because their human voice has been silences so early in their lives, that they do not even struggle or suffer or develop symptoms as the neurotic does.” They are normal not in what may be called the absolute sense of the word; they are normal only in relation to a profoundly abnormal society. Their perfect adjustment to that abnormal society is a measure of their mental sickness.
