Eric Voegelin, one of today's leading political theorists and author of the contemporary classic The New Science of Politics, here contends that certain modern movements, including Positivism, Hegelianism, Marxism and the "God is Dead" movement, are variants of the Gnostic tradition of antiquity. He attempts to resolve the intellectual confusion that has resulted from the dominance of gnostic thought by clarifying the distinction between political gnosticism and the philosophy of politics. Highly provocative, this book is essential reading for students of modern politics, philosophy, and religion.
