In this biography -- translated for the first time into English -- German theologian Oswald Bayer describes the life and work of journalist-theologian Johann Georg Hamann (1730 1788). At a time when it seemed that the forces of secularization were attempting to claim the future, Hamann churned out small publications aimed at undermining the Enlightenment zeitgeist, turning its assumptions upside down and skewering its pretensions. Although largely forgotten until recent times, Hamann as radical dissenter -- whom Goethe called the "brightest man of his age" -- remains relevant today, as Bayer shows in this book.
