Professor Floyd’s Personal Website.

Professor Floyd joined the faculty at Boston University from the City College of New York and C.U.N.Y. (1990-1994), where she served as Associate Director of the Ph.D. program at the Graduate Center (1993-4). A philosopher of logic, mathematics and science, her research focuses on the interplay between logic and philosophy from the 18th to the 20th centuries. She is especially known for her work on Wittgenstein’s philosophy of logic and mathematics, but writes widely about such notions as the nature and limitations of philosophical and axiomatic methods, logic and foundations of mathematics, simplicity and modernism in mathematics and the arts, skepticism and rule-following, the concepts of “rigor” and the “everyday” in early twentieth-century philosophy, and the history of American philosophy and pragmatism in relation to European twentieth century analytic philosophy (Vienna Circle, Carnap, Quine, Putnam, Rawls, Cavell) . She has furthered the historical study of 20th century analytic philosophy in an international context, holding Visiting Professorships at the Universities of Vienna, Paris (I, Panthéon-Sorbonne), and Bordeaux (Michel de Montaigne). She co-edited Future Pasts: The Analytic Tradition in Twentieth Century Philosophy (with S. Shieh, Oxford University Press, 2001/online 2004), Philosophy of Emerging Media: Understanding, Appreciation, Application (with J.E. Katz, Oxford University Press 2016) and the soon to appear Philosophical Explorations of the Legacy of Alan Turing: Turing 100 (with A. Bokulich, Springer Boston Studies in the Philosophy of Science Series). She is currently working on a manuscript treating the impact on Wittgenstein in the mid-1930s of Turing’s and Gödel’s undecidability and incompleteness results. For 2016-18 she has been awarded a Mellon Sawyer Seminar Grant for faculty development (with James E. Katz and Russell Powell) to pursue research into the philosophy of emerging computational technologies and the ways they are transforming social, ethical, and philosophical aspects of everyday life. She is also co-directing The Mentoring Project For Pre-tenure Women Faculty in Philosophy.
