Contradiction, Quantum Mechanics, and the Square of Opposition
- J. Arenhart, D. Krause
- Philosophy
- 28 March 2014
We discuss the idea that superpositions in quantum mechanics may involve contradictions or contradictory properties. A state of superposition such as the one comprised in the famous Schrodinger’s…
Many entities, no identity
- J. Arenhart
- PhilosophySynthese
- 1 July 2012
It is argued that some objections raised by Jantzen against the separation of the concepts of ‘counting’ and ‘identity’ are misled and a definition of counting is presented in the context of quasi-set theory requiring neither the labeling nor the identity and individuality of the counted entities.
Is Identity Really so Fundamental?
- D. Krause, J. Arenhart
- PhilosophyFoundations of Science
- 19 July 2018
We critically examine the claim that identity is a fundamental concept. According to those putting forward this thesis, there are four related reasons that can be called upon to ground the…
Semantic analysis of non-reflexive logics
- J. Arenhart
- Philosophy, Computer ScienceLogic Journal of the IGPL
- 1 August 2014
It is argued that there is a reasonable formal semantics for non-reflexive logics with interesting features, and it is suggested that issues concerning the representational apparatus rely more heavily on metaphysical assumptions then the foes of non-individuality are willing to concede.
Potentiality and Contradiction in Quantum Mechanics
- J. Arenhart, D. Krause
- Philosophy
- 7 June 2014
Following J.-Y.Beziau in his pioneer work on nonstandard interpretations of the traditional square of opposition, we have applied the abstract structure of the square to study the relation of…

- J. Arenhart
- PhilosophySynthese
- 4 August 2020
This paper distinguishes two conflicting programs entangled in the proposal, and argues that the first part of the program does not succeed, and fails to engage with dialetheism in a legitimate dispute about interpretation of paraconsistency.

Ontic Structural Realism is a version of realism about science according to which by positing the existence of structures, understood as basic components of reality, one can resolve central…
Why Non-individuality? A Discussion on Individuality, Identity, and Cardinality in the Quantum Context
- J. Arenhart, D. Krause
- Philosophy
- 1 February 2014
Recently, in the debate about the ontology of quantum mechanics some authors have defended the view that quantum particles are individuals in a primitive sense, so that individuality should be…
