This workshop is a follow-up to a previous meeting on the Origins and Varieties of Logicism (http://www.iusspavia.it/news.php?id=2262&menu=menu-news.html). Among traditional foundational programmes in the philosophy of mathematics, Logicism still attracts much attention, witnessed by a revival of studies on its origins and on logicist-oriented issues tightly connected with present research developments. By focussing on these issues, and extending the range of topics from the previous conference, the workshop aims at providing both further historical investigations on full-flegded Logicists and other authors standing in connection or opposition to such a view – such as Frege, Wittgestein, Ramsey, and Hilbert – and theoretical explorations of recent research – such as numerical cognition, ordinal abstraction, Neo-Logicism – in order to shed new light on the legacy of various kinds of Logicism for contemporary philosophy of mathematics.
