The logic of the nation: Nationalism, formal logic, and interwar Poland

open access: yesStudia Historiae Scientiarum, 2018
Between the World Wars, a robust research community emerged in the nascent discipline of mathematical logic in Warsaw. Logic in Warsaw grew out of overlapping imperial legacies, launched mainly by Polish-speaking scholars who had trained in Habsburg ...

Was Hugh MacColl a logical pluralist or a logical monist? A case study in the slow emergence of metatheorising

open access: yesPhilosophia Scientiæ, 2011
In the mid- and late 1900s Bertrand Russell and Hugh MacColl had a non-discussion about implication and existence, as parts of a dispute over the nature of logic.

Chemical AI in the Limelight: The Contribution of Photochromic Materials and Oscillatory Chemical Reactions

open access: yesAdvanced Optical Materials, Volume 13, Issue 15, May 27, 2025.
Photochromic compounds are versatile ingredients for the development of Chemical AI. When they are embedded in a tight microenvironment, they become Markov blankets. They are also valuable for processing Boolean and Fuzzy logic. They contribute to neuromorphic engineering in wetware based on opto‐chemical signals exchanged with oscillatory chemical ...

A Comprehensive Study on the Different Approaches of the Symmetric Difference in Nilpotent Fuzzy Systems

open access: yesMathematics
This paper comprehensively examines symmetric difference operators within logical systems generated by nilpotent t-norms and t-conorms, specifically addressing their behavior and applicability in bounded and Łukasiewicz fuzzy logic systems.

Legitimacy in polycentric groundwater governance: Framework conditions identified in Nebraska's Natural Resource Districts

open access: yesEnvironmental Policy and Governance, Volume 35, Issue 2, Page 187-200, April 2025.
Abstract This study considers how and why agricultural groundwater users would limit their own water consumption. We find that voluntary governance arrangements are based on a form of legitimacy that stems from informal social processes. Agricultural irrigation reform in Nebraska, U.S.

Encoding de Finetti's coherence within Łukasiewicz logic and MV-algebras

open access: yes, 2023
The present paper investigates proof-theoretical and algebraic properties for the probability logic FP(Ł,Ł), meant for reasoning on the uncertainty of Łukasiewicz events. Methodologically speaking, we will consider a translation function between formulas

Consistency Degrees of Theories in Łukasiewicz Fuzzy and n-Valued Propositional Logic Systems

open access: yesApplied Computational Intelligence and Soft Computing, 2010
By means of theory of truth degrees of formulas, according to deduction theorems and completeness theorems, the new concepts of consistency degrees and polar index for general theories in Łukasewicz fuzzy and n-valued propositional logic systems are ...

The closed future

open access: yesTheoria, Volume 91, Issue 2, April 2025.
Abstract Many philosophers take for granted that there is a strong pre‐theoretical intuition that the future is open and that it is worth trying to make sense of that intuition in theoretical terms. In this paper, I give a characterisation of the ordinary intuition in terms of three elements: our sense of agency, the difference in normativity between ...
