Newly published: "Even big data does not speak for itself", by Jürgen Landes, Synthese, 2026, doi.org/10.1007/s112...

Even big data does not speak for itself - Synthese

This paper demonstrates that in an important class of data-integration problems even Big Data cannot speak for itself: marginal probabilities provided by large and unbiased datasets do not determine a unique joint probability distribution. Big Data must instead be accompanied by further reasoning methodologies for handling unavoidable uncertainties. I assess how Bayesian approaches handle this underdetermination and argue that they face practical challenges when dealing with Big Data that does not speak for itself.

Together with Jürgen Landes I started the Journal of Mathematical Philosophy. Please send us your work! mathematicalphilosophy.org/mathphil

Munich Center for Mathematical Philosophy@lmu-mcmp.bsky.social · last wk.

Journal launch: The *Journal of Mathematical Philosophy* aims to publish high-quality research articles in all areas of mathematical philosophy (broadly understood), offering open access at no cost to authors. Submissions of manuscripts are now welcome at: mathematicalphilosophy.org/mathphil

I had a good time speaking as an MCMP fellow on metabolism, cognition, and computation. The Summer School Students have things to say about cognition, computation, and computationalism. #philsci, #cogsci, #philsky

We had a wonderful 2026 Summer School for Widening Participation in Mathematical Philosophy at @lmu.de! Many thanks to the terrific participants from all over the world and to the fantastic lecturers Dunja Šešelja [Bochum], Xueyin (Snow) Zhang [Berkeley], and @sabinaleonelli.bsky.social [@tum.de]!

Newly published: "Maximality Axioms and the Principle of Plenitude", by Nicola Bonatti, Erkenntnis, 2026, doi.org/10.1007/s106...

Maximality Axioms and the Principle of Plenitude - Erkenntnis

Hilbert’s (arithmetical) Axiom of Completeness asserts that the structure of the real numbers $$\mathbb {R}$$ R is maximal in the sense of not having a proper extension to an Archimedean ordered field. The more recent works of Ehrlich (2001), McGee (1997) and Aczel (1988) show that certain maximality conditions modeled upon Hilbert’s axiom provide unique characterizations of, respectively, the s-hierarchical ordered field of surreal numbers No, the well-founded hierarchy of pure sets $$\mathbb {V}_{\!k}$$ V k , and the non-well-founded hierarchy of Finsler-extensional sets $$\mathbb {V}_{\scriptscriptstyle \!F\!A\!F\!A}$$ V F A F A . The paper provides a comprehensive historical and theoretical reconstruction of this often overlooked chapter in the history of the axiomatic method. The historical reconstruction suggests that the maximality condition of non-extensibility arises as a natural axiom in the unique characterization of mathematical structures, as illustrated by the theories of (s-hierarchical non-)Archimedean continua and (non-)well-founded sets. The theoretical reconstruction argues that the maximality condition of non-extensibility is the formal explication of the heuristic principle of Plenitude, as usually adopted to describe the intuitive ‘‘fullness” of punctiform continua and the cumulative hierarchy of sets.

Our new DFG-funded project “Procedural Anchors: How Communication Order Shapes Disinformation” is part of the Priority Programme Re:DIS. Prof. Stephan Hartmann and Lilian von Bressensdorf will study how communication order shapes beliefs—and how better deliberation can counter disinformation.

Many thanks to Stephan Hartmann for the invitation to visit LMU Munich. I had a wonderful time meeting colleagues across the university and was honored to give a Philosophy & Physics Colloquium talk, “AI Meets Philosophy of Science: Towards a Foundation of AI.” Link: www.youtube.com/watch?v=aMyk...
