  1. Zwart and Franssen’s Impossibility Theorem Holds for Possible-World-Accounts but Not for Consequence-Accounts to Verisimilitude.Gerhard Schurz & Paul Weingartner - 2010 - Synthese 172 (3):415 - 436.
    Zwart and Franssen’s impossibility theorem reveals a conflict between the possible-world-based content-definition and the possible-world-based likeness-definition of verisimilitude. In Sect. 2 we show that the possible-world-based content-definition violates four basic intuitions of Popper’s consequence-based content-account to verisimilitude, and therefore cannot be said to be in the spirit of Popper’s account, although this is the opinion of some prominent authors. In Sect. 3 we argue that in consequence-accounts , content-aspects and likeness-aspects of verisimilitude are not in conflict with each other, but (...)

    Matrix-Based Logic for Application in Physics.Paul Weingartner - 2009 - Review of Symbolic Logic 2 (1):132-163.
    The paper offers a matrix-based logic (relevant matrix quantum physics) for propositions which seems suitable as an underlying logic for empirical sciences and especially for quantum physics. This logic is motivated by two criteria which serve to clean derivations of classical logic from superfluous redundancies and uninformative complexities. It distinguishes those valid derivations (inferences) of classical logic which contain superfluous redundancies and complexities and are in this sense from those which are or in the sense of allowing only the most (...)

    The Need for Pluralism of Causality.Paul Weingartner - 2016 - Logic and Logical Philosophy 25 (4):461-498.
    It will be shown in this article that a pluralism of causality is needed. Not only, as might be expected, for such different domains as natural sciences and humanities, but even within the domain of physics different causal relations are necessary. This will be illustrated with examples from Classical Mechanics and Special Relativity, Thermodynamics and Quantum Mechanics. In these domains causal relations differ in their properties. A model for five types of causal relations is provided that is based on a (...)

    Basis Logic for Application in Physics and Its Intuitionistic Alternative.Paul Weingartner - 2010 - Foundations of Physics 40 (9-10):1578-1596.
    This article proposes a basic logic for application in physics dispensing with the Principle of Excluded Middle. It is based on the article “Matrix Based Logics for Application in Physics (RMQ) which appeared 2009. In his article with Stachow on the Principle of Excluded Middle in Quantum Logic (QL), Peter Mittelstaedt showed that for some suitable QLs, including their own, the Principle of Excluded Middle can be added without any harm for QL; where ‘without any harm for QL’ means that (...)

    An Alternative Propositional Calculus for Application to Empirical Sciences.Paul Weingartner - 2010 - Studia Logica 95 (1-2):233 - 257.
    The purpose of the paper is to show that by cleaning Classical Logic (CL) from redundancies (irrelevances) and uninformative complexities in the consequence class and from too strong assumptions (of CL) one can avoid most of the paradoxes coming up when CL is applied to empirical sciences including physics. This kind of cleaning of CL has been done successfully by distinguishing two types of theorems of CL by two criteria. One criterion (RC) forbids such theorems in which parts of the (...)

  10. God's Existence: Can It Be Proven? A Logical Commentary on the Five Ways of Thomas Aquinas.Paul Weingartner - 2011 - European Journal for Philosophy of Religion 3 (1):243 - 248.
    The aim of the book is to show that the ’five ways’ of Thomas Aquinas, i.e., his five arguments to prove the existence of God, are logically correct arguments by the standards of modern predicate logic. In the first chapter this is done by commenting on the two preliminary articles preceding the five ways in which Thomas Aquinas points out that on the one hand the existence of God is not self-evident to us and on the other hand, that, similar (...)

    SummaryIn the first part of the paper necessary conditions for the rationality of the notions of belief, knowledge, and assumption are given: Among the different conditions it is stressed that one needs two different concepts of belief, one such that if someone knows something he also believes it, the other exclusive such that if someone knows something he need not to believe it and if he believes it he does not yet know it. Another important point is that deductive infallibility (...)

    This paper investigates Brentano's criticism of the correspondence theory of truth within the context of a discussion of his ontological assumptions. Brentano's interpretation of the formula Veritas est adaequatio rei et intellectus and of the principle ens et verum convertuntur is shown to fit into the history of these principles and into modern interpretations like that of Tarski.

    The purpose of this paper is to discuss conditions of rationality for scientific research (SR) where “conditions” are understood as “necessary conditions”. This will be done in the following way: First, I shall deal with the aim of SR since conditions of rationality (for SR) are to be understood as necessary means for reaching the aim (goal) of SR. Subsequently, the following necessary conditions will be discussed: Rational Communication, Methodological Rules, Ideals of Rationality and its Realistic Aspects, Methodological and Ontological (...)

    A Note on Jaakko Hintikka’s “Knowledge and Belief”.Paul Weingartner - 1994 - Grazer Philosophische Studien 49 (1):135-147.
    Jaakko Hintikka's concept of belief (aBp) as presented in his Knowledge and Belief is such that in his epistemic logic aKp —> aBp is a thesis. This concept (B-belief) is one important kind of belief and can be contrasted with a different concept of belief (G-belief, denoted by 'aOp') not discussed in Hintikka's book. It is to some extent opposite to the one above in the sense that it is knowledge-exclusive, whereas Hintikka's is knowledge-inclusive. This is shown by the thesis (...)

    With his theory of descriptions Russell wanted to solve two problems concerning denotation and reference, which are formulated here as Problem I and Problem II. After presenting each problem, we describe the main points of Russell’s solution. We deal with Russell’s concepts of existence and then elaborate his presuppositions concerning the relation of denoting and referring. Next we discuss the presuppositions or principles which underlie Russell’s understanding of the objects of reference. These principles are such that if the objects of (...)

    The paper is divided into the following sections: In the first section a short historical survey is given which presents precursors of both Tarski’s truth-condition and Tarski’s truth definition . Secondly some purported objections against Tarski’s truth condition are stated and two important presuppositions of Tarski’s truth condition are analyzed. Thirdly TTC is enlarged in different ways as to incorporate the preconditions explicitly. Finally in the fourth section it will be shown how the revised T-conditions solve different versions of the (...)

    The first part of the papaer contains desiderata for a realistic epistemic system as opposed to idealistic ones. One of the main characteristics of idealistic epistemic systems is their deductive infallibility or deductive omniscience. The system presented avoids deductive infallibility though having a strong concept of knowledge. The second part contains the theorems of the system. The system is detailed in so far as it distinguishes between two concepts of belief and one of assumption and interrelates them to the concept (...)
