During the past thirty years, people from all the civilized countries of the earth have consulted me. I have treated many hundreds of patients. Among all the patients in the second half of life---that is to say, over thirty-five---there has not been one whose problem in the last resort was not that of finding a religious outlook on life. It is safe to say that everyone of them fell ill because he had lost that which the living religions of every age have given to their followers, and none of them has really been healed who did not regain his religious outlook.
