From Preface to The Screwtape Letters

“The greatest evil is not now done in those sordid ‘dens of crime’ that Dickens loved to paint. It is not done even in concentration camps and labour camps. In those we see the final result. But it is conceived and ordered (moved, seconded, carried, and minuted) in clean, carpeted, warmed, and well-lighted offices, by quiet men with white collars and cut fingernails and smooth-shaven cheeks who do not need to raise their voice.”
~C. S. Lewis
