I always have a quotation for everything - it saves original thinking.

Praise God (or whatever it is) from (if direction exists) whom (if personality exists) all blessings (if that word corresponds to any percept of objective reality) flow (if Heraclitus and Bergson and Einstein are correct in stating that everything is more or less flowing about).

Forgiveness is the one unpardonable sin.

Do you solemnly swear never to conceal a vital clue from the reader? Do you promise to observe seemly moderation in the use of gangs, conspiracies, Super Criminals and Lunatics and utterly and forever to forswear Mysterious Poisons unknown to science? Will you honor the King's English? ... If you fail to keep your promise, may other writers steal your plots and your pages swarm with misprints.

A facility for quotation covers the absence of original thought.

For God's sake, let's take the word 'possess' and put a brick round its neck and drown it ... We can't possess one another. We can only give and hazard all we have.
