A companion to Philosophical and Theological Papers 1958-1964 (Volume 6 in the Collected Works of Bernard Lonergan series), this anthology contains Lonergan´s lectures on philosophy and theology given during the later period of his life, 1965-1980. These papers document his development in the discipline during the years leading up to the publication of Method in Theology, and beyond to 1980 when he was more engaged in his writings and seminars on macroeconomics. Philosophical and Theological Papers 1965-1980 is divided into five sections, forming units on the basis of dates. The three central sections are each a set of lectures respectively given at the Massachusetts Institute of Technology, Gonzaga University in Spokane, and Trinity College (University of Toronto). Although there is some repetition amongst the lecture sets and in relation to other more familiar works, this repetition displays occasional new turns of phrase that the careful reader will note. In at least one instance, familiar material suddenly opens out onto expressions not to be found anywhere else in Lonergan´s work.
