The Danish philosopher Kierkegaard is one of the master thinkers of the modern age, a defining influence on existentialism and on twentieth-century theology, and this brilliantly tailored selection from his vast and varied writings-made by the great English poet W.H Auden-is a perfect introduction to his work. Auden's inspired and incisive response to a thinker who had done much to shape his own beliefs is a fundamental reading of an author whose spirit remains as radical as ever more than 150 years after he wrote.
