“Not really” is the new “No.”  Or so I thought before running across this encyclopedic account.

While you (we) are at it (I?), consider the New Yorker cartoon by Edward Koren cited in Times Literary Supplement, 9/23/11 (but earlier in a textbook, Philosophy: An Introduction to the Art of Wondering, by James L. Christian, originally published in 1973), in which the devil laments:

It’s getting much harder for me to distinguish good from evil.  All I’m certain about is what’s appropriate and inappropriate.

Quoted by Rae Langton, reviewing Terry Eagleton’s On Evil (Yale).
