Workshop hosted by Philosophies et Rationalités (PHIER) of Blaise Pascal University and the Institut Universitaire de France (IUF), with the support of the Institut de Recherche Philosophique (IREPH) of Paris Ouest University.

Organizers: Sébastien Gandon (PHIER), Brice Halimi (IREPH).

Logicism is today a hot topic in philosophy of mathematics. It is also a standpoint whose coherence and unity are difficult to delineate, owing to the diversity of all logicist philosophical stances and to the heterogeneity of the issues at stake. In the literature, however, the debates usually focus on the relationship between logicism and its main rivals (structuralism, intuitionism, practice-based approaches, etc?), which contributes to gloss over deep discrepancies among logicists. The aim of this workshop is to gather philosophers working from within a logicist perspective (or from within a perspective close to logicism) so as to question the coherence and unity of the movement - that is, both to make apparent the conceptual tensions that divide logicism, and to outline possible rapprochements between different logicist approaches of mathematics.
