Last week's quotation was, as many of you know, written by Raymond Chandler.
"...who is not himself mean" to me is the key element. He can be tough, even vicious, but this cannot stem from an essential meanness. Chandler, masterful in his word choice, would have been aware that claiming that somone is not mean stops short of claiming that he is nice or kind.
I very much enjoyed your various comments and perspectives. A slumming angel indeed. Please, please, please do not look up the quotations or Google them. It's far more interesting to hear your observations when they come from prior knowledge or guesswork.
Now, here's this week's quotation:
"The hottest places in Hell are reserved for those who, in a period of moral crisis, maintain their neutrality."
Have at it.
