The average human being finds it helpful to free himself from his impressions by "pouring by out his heart" to someone. Like a sponge, the soul saturates itself; like a sponge, it must be squeezed dry before it can fill itself up again. Then it happens that the soul cannot rid itself of its impressions. Such persons are soul-sick and we recognise by those who suffer from soul-sickness the fact that they sedulously shun new impressions. Every disease of the soul rests ultimately upon a secret. For, as Grillparzer says, every heart has its secrets that it anxiously hides even from itself. The tremendous power of the Roman Catholic Church is even to-day due to the fact that it enables its members to confess their most secret sufferings from time to time and to be absolved.
