The Legitimacy of the Modern Age  (English, Paperback, Blumenberg Hans)

In this major work, Blumenberg takes issue with Karl Loewith's well-known thesis that the idea of progress is a secularized version of Christian eschatology, which promises a dramatic intervention that will consummate the history of the world from outside. Instead, Blumenberg argues, the idea of progress always implies a process at work within history, operating through an internal logic that ultimately expresses human choices and is legitimized by human self-assertion, by man's responsibility for his own fate.
