This seminar is devoted to exploring substantive as well as methodological issues in the history and philosophy of science. Science is construed broadly and the issues considered range from epistemic and historiographic questions to issues of relevance and accountability. Topics include the presuppositions and practice of a range of life sciences, earth sciences, and social sciences as well as the physical sciences and mathematics. In the physical sciences, its interests range from antiquity to contemporary quantum theory. In the life sciences and social sciences, the fields considered include various forms of historical, evolutionary inquiry (in biology, geology, and the historical social sciences), biotechnology and ecology, economics, psychology, and cognitive science, and interpretive social inquiry. The membership of this seminar includes scientists, philosophers, and historians. Most sessions take place in conjunction with the New York City History of Science Working Group.
