War makes death real to us, and that would have been regarded as one of its blessings by most of the great Christians of the past. They thought it good for us to be always aware of our mortality. I am inclined to think they were right. All the animal life in us, all schemes of happiness that centred in this world, were always doomed to a final frustration. In ordinary times only a wise man can realise it. Now the stupidest of us knows.
