The renowned Christian theologian Bernard Lonergan was also a professor, teaching courses on theological method at universities in Canada, the United States, and Italy. This volume records his lectures and teaching materials, thus preserving and elucidating his intellectual development between the publication of Insight in 1957 and Method in Theology in 1972.

The present volume contains a record of the lectures delivered in 1962 (Regis College, Toronto), 1964 (Georgetown University), and 1968 (Boston College). This is the most 'interactive' volume yet published in the Collected Works series. The audio recordings of the 1962 and 1968 lectures are now available on the website www.bernardlonergan.com, as are PDF files of original papers from his 1964 institute at Georgetown. These lectures help to elucidate the development of Lonergan's ideas on such key notions as horizon, conversion, and meaning, as well as his evolving opinion on how best to divide theology into fields of specialization.
