The period during which Bernard Lonergan delivered the eleven lectures in this volume was one of important transition for him: he was moving rapidly toward a new conception of theology and its method; and he was on the verge of what is now recognized as a major breakthrough in his thought on method, the idea that came to him in February 1965 of the eight functional specialities. While the lectures maintain a continuity with Lonergan's previous work, they also reveal new and significant ideas, especially in regard to his drive toward a new conception of theology as a whole, and his particular concern for the relevance of theology to the spiritual life. The lectures here include `The Redemption,' `Method in Catholic Theology,' `The Philosophy of History,' `The Origins of Christian Realism,' `Time and Meaning,' `Consciousness and the Trinity,' `Exegesis and Dogma,' `The Mediation of Christ in Prayer,' `The Analogy of Meaning,' `Philosophical Positions with Regard to Knowing,' and `Theology as Christian Phenomenon.' This volume provides a key to understanding the development of Lonergan's philosophical and theological thought, his major influences, and the pivotal moments of transition in the road leading up to Method in Theology and beyond.
