First session - 20th May 2026 This session of the seminar will feature: 15:00 - 16:00 (CET) Valeriya Chasova (Utrecht University), Deborinians and mechanists per se and as precursors to Western philosophers of science PRESENTATION ABSTRACT From mid-20th century on up to the recent times Western philosophers of science have been concentrating in particular on two questions: the choice between ordinary or scientific sources for metaphysics, and the emergence or reduction among branches of science (and their objects). It turns out that on either question they were preceded by the two groups of Soviet philosophers of science, dialectics or deborinians and mechanists. Their discussions date back already to the early 20th century, when the Western research was dominated by the anti-metaphysical Vienna Circle. Moreover, the Soviet debate also has its own originality which might be inspiring for philosophers of today. In the talk will be presented the context in which these now less-known groups of philosophers were existing, their own debate, and its comparison with modern ones.

Dear EPSA members, In our first newsletter of 2026, we want to announce some good news and update you on some recent developments pertaining to EPSA. The good news is that we have now secured locations not only for EPSA27 but also for EPSA29! We were very lucky this year to receive nothing less than four bids to host EPSA27; all bids were very strong and carefully prepared, and the Steering Committee found it very difficult to decide. Eventually, we settled on Warsaw, Poland, for 2027 (with Marcin Milkowski and Hajo Greif as co-chairs) and Ljubljana, Slovenia, for 2029 (with Borut Trpin as chair). More details will follow in due course, but for now, we can all be happy that the next two EPSAs are in good hands and will take place in splendid locations! This is also a good moment to thank the Steering Committee members who have concluded their term (Lilia Gurova, Federica Russo, Marcel Weber, Catherine Herfeld, Edouard Machery and Caterina Marchionni) and in particular my predecessor Stéphanie Ruphy as EPSA President. Thanks to their good work, the current Steering Committee has found EPSA to be in excellent shape, which will allow us to continue to serve the philosophy of science community in Europe in constructive ways. We also want to thank Dunja Šešelja and Mathias Frisch, who have completed their terms as Editors-in-Chief of the European Journal for Philosophy of Science, and to welcome Samuel Fletcher and Catherine Herfeld as the new Editors-in-Chief of EJPS. Speaking of EJPS, we will soon be announcing the Call for Papers for the Proceedings of EPSA25, with Julie Jebeile as guest editor for the Proceedings (plus a team of co-editors to be announced shortly). Finally, the EPSA BlueSky account is now managed by Simon Lohse; if you are on BlueSky, please follow us there at https://bsky.app/profile/epsaphilsci.bsky.social Warm Regards, Catarina Dutilh Novaes and the EPSA Steering Committee
