C.S. Lewis has the tongue of an angel, albeit a demonic one, in his affectionately signed Screwtape Letters.  The book is written entirely as letters from a doting uncle to his junior tempter nephew, Wormwood, who is out in the world on his first assignment. It is Wormwood’s goal to tempt his patient into paths of sin and worldliness, and his dear old uncle is ready with advice.
The book is an entertaining look at the foibles of humanity, and the little hypocricies that can be turned against a well-meaning soul. I found it quite insightful of human nature, and also enjoyed the twisting words of the uncle, and petty quarrels between he and the nephew.
The version I read included ‘Screwtape Proposes a Toast’ in the afterward, which summed up the dangers of democracy, when used as a slogan, most succinctly. Forewarned is forearmed, however, so the College of Tempters may need to take note and go easy on the feasting, for fear of a famine.
