My friend, Kermit Long, told me of a visit he made to Albert Schweitzer in Africa. Long went out one day and painted one of the buildings to relieve his guilt over the contrast of his life-style and that of Schweitzer.

At dinner that evening the following conversation took place:

Schweitzer: How are you today, Dr. Long?

Long: Wonderful! Today I have a clear conscience.

Schweitzer: Dr. Long, a clear conscience is the invention of the devil.
