‘Fair or Foul’ considers different aspects of ambition and its place in our lives. It asks: what does success mean? When is enough enough? And is Lady Macbeth right to suggest that only those with the ‘illness’ of ambition achieve the highest goals? Stefan Stern draws on the major themes of Macbeth and discusses how they can be applied to ambition in modern life. From the success of the first US woman vice president, Kamala Harris, the obstacles she faced and the possibilities that still lie ahead, to Boris Johnson’s young aspirations to be ‘world king’ and the pathological intensity of his ambition, Stern considers the careers and personal lives of politicians, sports stars and business people, to name a few, to illuminate this strange and powerful driver.
