What does it profit a man if he gain the whole world and lose – how does the quotation run? – his own soul?

– Oscar Wilde

The Picture of Dorian Gray, Chapter 19. Lord Henry tells Dorian how he was walking through the park on Sunday and saw a group of people listening to a preacher who asked this question. Henry described him as "an uncouth Christian in a mackintosh" and "hysterical." But Dorian is not amused by Henry. The quotation is from Mark 8:36 in the Bible.
