Carl Gustav Jung .: La vie symbolique

"I have frequently seen people become neurotic when they content themselves with inadequate or wrong answers to the questions of life. They seek position, marriage, reputation, outward success or money, and remain unhappy and neurotic even when they have attained what they were seeking. Such people are usually confined within too narrow a spiritual horizon. Their life has not sufficient content, sufficient meaning. If they are enabled to develop into more spacious personalities, the neurosis generally disappears. For that reason the idea of development was always of the highest importance to me.

The majority of my patients consisted not of believers but of those who had lost their faith. The ones who came to me were the lost sheep. Even in this day and age the believer has the opportunity, in his church, to live the "symbolic life." [...] But to live and experience symbols presupposes a vital participation on the part of the believer, and only too often this is lacking in people today. In the neurotic it is practically always lacking. In such cases we have to observe whether the unconscious will not spontaneously bring up symbols to replace what is lacking. But then the question remains of whether a person who has symbolic dreams or visions will also be able to understand their meaning and take the consequences upon himself."
