Anthony Burgess's Tremor of Intent (1966), his satire of espionage novels, bears a double epigraph. The first is from W. H. Auden:
But between the day and night
The choice is free to all, and light
Falls equally on black and white.
The second is from T. S. Eliot:
The worst that can be said of most of our malefactors, from statesmen to thieves, is that they are not men enough to be damned. >>
