Modern man sees with one eye of faith and one eye of reason. Consequently, his view of history is confused. For centuries, the history of the Western world has been viewed from the Christian or classical standpoint—from a deep faith in the Kingdom of God or a belief in recurrent and eternal life-cycles.

The modern mind, however, is neither Christian nor pagan—and its interpretations of history are Christian in derivation and anti-Christian in result. To develop this theory, Karl Löwith—beginning with the more accessible philosophies of history in the nineteenth and eighteenth centuries and working back to the Bible—analyzes the writings of outstanding historians both in antiquity and in Christian times.
