The papers of Paul Ramsey span the years 1934 to 1984. Included are correspondence, memoranda, book reviews, typescripts, reprints, drafts of books and articles, clippings, lecture notes and outlines, course outlines, examinations and handouts, writings of Ramsey and others, news releases, theses and dissertations, and cassette tapes. The principal focus of the collection reflects the direction of the teaching and writing career of Ramsey, principally while a professor in the Department of Religion at Princeton University. These primarily professional papers relate to his major fields of interest: theology, philosophy, and the humanities. In particular, Ramsey's chief specialty as a teacher and scholar has been Christian ethics, beginning with the publication of his classic, Basic Christian Ethics in 1950. There followed writings in ethical methodology, "situation ethics," marriage, and sexual ethics. In the 1960s he expanded the scope of his research and writing to include the ethics of warfare and nuclear deterrence, and in the 1970s turned to medical ethics topics, such as fetal research, abortion, and in vitro fertilization.
