As a rule, the life of a young person is characterized by a general unfolding and a striving toward concrete ends; his neurosis, if he develops one, can be traced to his hesitation or his shrinking back from this necessity. But the life of an older person is marked by a contraction of forces, by the affirmation of what has been achieved, and the curtailment of further growth. His neurosis comes mainly from his clinging to a youthful attitude which is now out of season. Just as the youthful neurotic is afraid of life, so the older one shrinks back from death.
