I have discovered the most exciting, the most arduous literary form of all, the most difficult to master, the most pregnant in curious possibilities. I mean the advertisement.

The surest way to work up a crusade in favor of some good cause is to promise people they will have a chance of maltreating someone. To be able to destroy with good conscience, to be able to behave badly and call your bad behavior 'righteous indignation' — this is the height of psychological luxury, the most delicious of moral treats.
