Sir Mervyn King, the Governor of the Bank of England, this week called the current financial crisis “the most serious… since the 1930s, if ever”, in justification for a further £75 billion of “quantitative easing”. Since Sir Mervyn cited the chaos of the inter-war years, it seems appropriate to quote Winston Churchill: “Want of foresight, unwillingness to act when action would be simple and effective, lack of clear thinking, confusions of counsel, until the emergency comes, until self-preservation strikes its jarring gong – these are the features that constitute the endless repetition of history.”
