This is a marvellous blog written by robstroud on C.S. Lewis’ understanding of an atomic bomb threat – alike the one we are living through today. Here just a quote from Lewis:
If we are all going to be destroyed by an atomic bomb, let that bomb when it comes find us doing sensible and human things—praying, working, teaching, reading, listening to music, bathing the children, playing tennis, chatting to our friends over a pint and a game of darts—not huddled together like frightened sheep and thinking about bombs. They may break our bodies (any microbe can do that) but they need not dominate our minds.
