Metaphysics re- quired from a philosopher to reveal the axioms of his teaching. It declared the law of contradiction as the most certain of all principles and axioms. This article proves that the Aristotelian definition of truth makes it necessary to accept the ontological formulations of all the three main laws of thought as axioms of first philosophy. This article points out the absence of any reference in Metaphysics on Categorias and vice versa. This circumstance questions if could Aristotle be the author of both works? Authors of this article underline that the modern trend of meta-philosophical studies requires investigating the possibility of building the system of axiomatic philosophy.

The purpose of this paper is to present a new logic - uncertain propositional logic which can deal with both fuzziness by taking truth value semantics and randomicity by taking probabilistic semantics or possibility semantics. As the first step for purpose of establishing a logic system which completely reflect the uncertainty of the objective world, this logic will lead to a set of logical foundations for uncertainty theory as what classical logic done in certain or definite situations or circumstances. Keywords: Fuzziness; randomicity; UL-algebra; uncertain propositional logic. Mathematics Subject Classifications(2000): 03B60. 1 Introduction As one of the most important and one of the most widely used concepts in the whole area of modern academic or technologic research, uncertainty has been involved into study and applications more than twenty years. Now along with the quickly expanding requirements of developments of science and technology, people are having to face and deal with more and more problems tangled with uncertainty in the fields of natural science, engineering or technology or even in social science. To these uncertain prob- arXiv:1506.03123v1 [math.LO] 9 Jun 2015 lems, many traditional theories and methods based on certain conditions or certain circumstances are not so effective and powerful as them in the past.

DENOTING PHRASES AND NAMES Russell defines the class of denoting phrases as follows: “By ‘denoting phrase’ I mean a phrase such as any one of the following: a man, some man, any man, every man, all men, the present king of England, the centre of mass of the Solar System at the first instant of the twentieth century, the revolution of the earth around the sun, the revolution of the sun around the earth. Thus a phrase is denoting solely in virtue of its form.” (‘On Denoting’, 479) Russell’s aim in this article is to explain how expressions like this work — what they contribute to the meanings of sentences containing them.

Eckel Submitted to the Graduate Faculty as partial fulfillment of the requirements for the Master of Arts Degree in Philosophy The University of Toledo May 2014 Taking Gilles Deleuze to be a philosopher who is most concerned with articulating a ‘philosophy of difference’, Deleuze’s thought represents a fundamental shift in the history of philosophy, a shift which asserts ontological difference as independent of any prior ontological identity, even going as far as suggesting that identity is only possible when grounded by difference. Deleuze reconstructs a ‘minor’ history of philosophy, mobilizing thinkers from Spinoza and Nietzsche to Duns Scotus and Bergson, in his attempt to assert that philosophy has always been, underneath its canonical manifestations, a project concerned with ontology, and that ontological difference deserves the kind of philosophical attention, and privilege, which ontological identity has been given since Aristotle.

In this paper, IexaminecriticallysomeofthecentralfeaturesofVasiliev’sapproachtological theory, suggesting its relevance to contemporary debates in the philosophy of logic. IarguethatthereismuchofsignificantvalueinVasiliev’swork,whichdeserves close philosophical engagement. Keywords Vasiliev • logical pluralism • Revisability • a priori • negation 4.1 Introduction: Six Central Features of Vasiliev’s Approach to Logical Theory Nikolai Vasiliev’s approach to logical theory has a number of features. Six of them, in particular, are worth highlighting: (a) logical pluralism (there is a plurality of logics, depending on the subject matter under consideration); (b) logical revisability (certain logical laws can be revised depending on the subject matter); (c) logical non-a priorism (certain logical laws are empirically based); (d) logical contingency (given the empirical nature of some logical laws, they are ultimately contingent; in this context, issues regarding the scope of logic are also examined, with the accompanying distinction between laws of objects and laws of thought); (e) the nature of negation (negation is characterized via incompatibility; it is not just difference, nor is it grounded on absence, and it is inferred rather than perceived); and (f) logical commitment (why Vasiliev is not a dialetheist, after all). In this paper, I will examine each of these features, and suggest the relevance of many of Vasiliev’s proposals to contemporary philosophical reflection about the foundations of logic.

  • The Development of Laws of Formal Logic of Aristotle
    This paper is dedicated to my unforgettable friend Boris Isaevich Lamdon. The Development of Laws of Formal Logic of Aristotle The essence of formal logic The aim of every science is to discover the laws that could explain one or another phenomenon. Once these laws are discovered, then science proceed to study the other phenomena, which in the nature are of an infinite set. It is interesting to note that in the process of discovering a law, for example in physics, people make thousands of experiments, build proves, among them some experience, or evidence - useful for understanding a certain phenomenon, but other experiments or evidence proved fruitless. But it is found only with hindsight, when the law is already discovered. Therefore, with the discovering of the law it is enough to show 2 - 3 experiments or prove to verify its correctness. All other experiments were the ways of study and there is no need to repeat them, to understand how the law works. In the exact sciences, it is understood, and therefore the students studies only the information that is necessary to understand specific phenomena. By no means this is the case with the study of formal logic. Formal logic, as opposed to other sciences: physics, chemistry, mathematics, biology and so on, studies not an infinite number of phenomena in nature, but only one how a man thinks, how he learns the world surrounding us, and how people understand each other. In other words, what laws govern the logic of our thinking, i.e., our reasoning and judgments in any science or in everyday life.

  • Paradox and Foundation Zach Weber Submitted in Total Fulfilment of The
    Paradox and Foundation Zach Weber Submitted in total fulfilment of the requirements of the degree of Doctor of Philosophy May 2009 School of Philosophy, Anthropology and Social Inquiry The University of Melbourne This is to certify that - the thesis comprises only my original work towards the PhD, - due acknowledgement has been made in the text to all other material used, - the thesis is less than 100,000 words in length. Preface Dialethic paraconsistency is an approach to formal and philosophical theories in which some but not all contradictions are true. Advancing that program, this thesis is about paradoxes and the foundations of mathematics, and is divided accordingly into two main parts. The first part concerns the history and philosophy of set theory from Cantor through the independence proofs, focusing on the set concept. A set is any col- lection of objects that is itself an object, with identity completely determined by membership. The set concept is called naive because it is inconsistent. I argue that the set concept is inherently and rightly paradoxical, because sets are both intensional and extensional objects: Sets are predicates in extension. All consistent characterizations of sets are either not explanatory or not coherent. To understand sets, we need to reason about them with an appropriate logic; paraconsistent naive set theory is situated as a continuation of the original foundational project. The second part produces a set theory deduced from an unrestricted compre- hension principle using the weak relevant logic DLQ, dialethic logic with quantifiers. I discuss some of the problems involved with embedding in DLQ, especially related to identity and substitution.

  • Aristotle on Non-Contradiction: Philosophers Vs
    Journal of Ancient Philosophy J. anc. philos. (Engl. ed.), São Paulo, v.7, n.2. p. 51-74, 2013. ISSN 1981-9471 - FFLCH/USP DOI: http://dx.doi.org/10.11606/issn.1981-9471.v7i2p51-74 www.revistas.usp.br/filosofiaantiga Aristotle on Non-Contradiction: Philosophers vs. Non-Philosophers Jean-Louis Hudry USP, Brazil Abstract: Aristotle’s principle of non-contradiction (PNC) has been interpreted by Łukasiewicz through three distinct formulations, namely ontological, logical, and psychological. Many have criticized Łukasiewicz’s position, but they still maintain that Aristotle defends distinct formulations. In contrast, this paper shows that Aristotle suggests only one formulation of the PNC. This unique formulation belongs to philosophy as the first science, so that the philosophers think of the PNC as a necessarily true principle, owing to their meta-physical cognition of the nature of things. Yet, there is another way to understand this formulation. Indeed, the non-philosophers believe in the PNC, without being able to understand its necessary truth, due to their ignorance of philosophy. Thus, Aristotle has to convince them that the PNC is the most certain opinion of all, and his dialectical justifications are purposely weak, as they are only concerned with the defense of a common opinion. In Chapter 3 of Metaphysics Gamma, Aristotle introduces the so-called principle of non-contradiction (hereafter PNC).1 It is important to put this principle into context in order to understand why and how Aristotle introduces it: It is proper for the one who best cognizes (gnôrizonta) each genus to be able to state the most certain principles (archas) of an actual thing, so that the one who cognizes beings, qua beings (tôn ontôn hêi onta), will also be able to state the most certain principles of all things.

MARTIN August 2016 Copyright Richard S. Martin 2016 ALL RIGHTS RESERVED ABSTRACT This paper addresses two related issues of logic in the philosophy of Gottfried Leibniz. The first problem revolves around Leibniz’s struggle, throughout the period of his mature philosophy, to reconcile his metaphysics and epistemology with his antecedent theological commitments. Leibniz believes that for everything that happens there is a reason, and that the reason God does things is because they are the best that can be done. But if God must, by nature, do what is best, and if what is best is predetermined, then it seems that there may be no room for divine freedom, much less the human freedom Leibniz wished to prove.

  • Leibniz and the Principle of Sufficient Reason
    Leibniz and the Principle of Sufficient Reason by Owen Pikkert A thesis submitted in conformity with the requirements for the degree of Doctor of Philosophy Department of Philosophy University of Toronto © Copyright by Owen Pikkert 2018 Abstract Leibniz and the Principle of Sufficient Reason Owen Pikkert Doctor of Philosophy Department of Philosophy University of Toronto 2018 Leibniz’s principle of sufficient reason (PSR) is the claim that everything has an explanation. It rules out brute facts, inexplicable primitives, and purely random events. On the usual view, Leibniz grounds the PSR in purely descriptive truths. On my view, Leibniz grounds the PSR in this being the best of all possible worlds. God only creates the best, and a world in which the PSR is true is better than a world in which it is false. For the PSR ensures that the world has an explanatory structure, the investigation of which facilitates human happiness. This way of grounding the PSR faces at least two problems. The first problem is that it presupposes that the PSR is a contingent principle, even though most commentators take it to be necessary. But I argue that Leibniz is indeed committed to the contingency of the PSR. I demonstrate this by showing how, for Leibniz, PSR-violating entities such as vacua, atoms, and indiscernible bodies are possible but not actual. I also argue that the contingency of the ii PSR does not conflict with Leibniz’s other modal commitments. In particular, it does not conflict with the modal status of his principle of the identity of indiscernibles, nor with the modal status of his theory of truth.
