The majority of my patients consisted not of believers but of those who had lost their faith.
I have treated many hundreds of patients. Among those in the second half of life - that is to say, over 35 - 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 every one of them fell ill because he had lost that which the living religions of every age have given their followers, and none of them has really been healed who did not regain his religious outlook.
It is a common illusion to believe that what we know today is all we ever can know. Nothing is more vulnerable than scientific theory, which is an ephemeral attempt to explain facts and not an everlasting truth in itself.
