It is a great honor to be a focus for the group of authors assembled here. Though public mirrors seldom reflect self- images, we learn most about people, not only by their own words, but also by the company they keep. But enough said about people, let me turn to the topic. This book is about logical dynamics, a bundle of interests and a program that may not cover my whole work, but that definitely constitutes the largest chunk of what I have done over the last decades. Let me explain what it means to me. You may find what follows ideological, some people prefer context-free theorems—but I need such broader perspectives even for myself, to remind me of why I do the things I do—or even, why I do research at all. The main idea of logical dynamics is the pervasive duality between informa- tion-related actions and their products. Standard logical systems emphasize notions like formula or proof in the sense of static objects that can be viewed or even manipulated externally. But these objects are produced in activities of commu- nicating statements, engaging in reasoning, and many other intellectual skills. Interestingly, our natural language is often ambiguous in this respect between verbs or other activity-related expressions and static nouns. A dance is an activity I can engage in, but also an object that can be produced by dancing—and the same duality holds for many logical terms, like ‘‘statement’’ or ‘‘argument.’’ The idea of logical dynamics is to take this duality seriously, and bring the core logical activities explicitly into formal systems that satisfy the same standards of rigor as the ones that we know and love. This is possible, since activities and events, too, have a formal structure that lends itself to logical analysis. In this way, to borrow a happy phrase, ‘‘logic can be more than it is.’’ Over time, my view of what are logical core activities has evolved from single- agent acts of inference and observation to social scenarios involving more agents, with asking a question, perhaps, as the major instance of a basic logical act. This took some time, since this social turn went against central tenets of my upbringing. ix x Preface by Johan van Benthem Dutch Calvinists like me were raised with the idea that there are two modes of life. The horizontal mode looks at other people and what they think, the vertical one

  • Recent Work in Relevant Logic
    Recent Work in Relevant Logic Mark Jago Forthcoming in Analysis. Draft of April 2013. 1 Introduction Relevant logics are a group of logics which attempt to block irrelevant conclusions being drawn from a set of premises. The following inferences are all valid in classical logic, where A and B are any sentences whatsoever: • from A, one may infer B → A, B → B and B ∨ ¬B; • from ¬A, one may infer A → B; and • from A ∧ ¬A, one may infer B. But if A and B are utterly irrelevant to one another, many feel reluctant to call these inferences acceptable. Similarly for the validity of the corresponding material implications, often called ‘paradoxes’ of material implication. Relevant logic can be seen as the attempt to avoid these ‘paradoxes’. Relevant logic has a long history. Key early works include Anderson and Belnap 1962; 1963; 1975, and many important results appear in Routley et al. 1982. Those looking for a short introduction to relevant logics might look at Mares 2012 or Priest 2008. For a more detailed but still accessible introduction, there’s Dunn and Restall 2002; Mares 2004b; Priest 2008 and Read 1988. The aim of this article is to survey some of the most important work in the eld in the past ten years, in a way that I hope will be of interest to a philosophical audience. Much of this recent work has been of a formal nature. I will try to outline these technical developments, and convey something of their importance, with the minimum of technical jargon. A good deal of this recent technical work concerns how quantiers should work in relevant logic.

  • Relevant and Substructural Logics
    Relevant and Substructural Logics GREG RESTALL∗ PHILOSOPHY DEPARTMENT, MACQUARIE UNIVERSITY [email protected] June 23, 2001 http://www.phil.mq.edu.au/staff/grestall/ Abstract: This is a history of relevant and substructural logics, written for the Hand- book of the History and Philosophy of Logic, edited by Dov Gabbay and John Woods.1 1 Introduction Logics tend to be viewed of in one of two ways — with an eye to proofs, or with an eye to models.2 Relevant and substructural logics are no different: you can focus on notions of proof, inference rules and structural features of deduction in these logics, or you can focus on interpretations of the language in other structures. This essay is structured around the bifurcation between proofs and mod- els: The first section discusses Proof Theory of relevant and substructural log- ics, and the second covers the Model Theory of these logics. This order is a natural one for a history of relevant and substructural logics, because much of the initial work — especially in the Anderson–Belnap tradition of relevant logics — started by developing proof theory. The model theory of relevant logic came some time later. As we will see, Dunn's algebraic models [76, 77] Urquhart's operational semantics [267, 268] and Routley and Meyer's rela- tional semantics [239, 240, 241] arrived decades after the initial burst of ac- tivity from Alan Anderson and Nuel Belnap. The same goes for work on the Lambek calculus: although inspired by a very particular application in lin- guistic typing, it was developed first proof-theoretically, and only later did model theory come to the fore.

  • Consequence and Degrees of Truth in Many-Valued Logic
    Consequence and degrees of truth in many-valued logic Josep Maria Font Published as Chapter 6 (pp. 117–142) of: Peter Hájek on Mathematical Fuzzy Logic (F. Montagna, ed.) vol. 6 of Outstanding Contributions to Logic, Springer-Verlag, 2015 Abstract I argue that the definition of a logic by preservation of all degrees of truth is a better rendering of Bolzano’s idea of consequence as truth- preserving when “truth comes in degrees”, as is often said in many-valued contexts, than the usual scheme that preserves only one truth value. I review some results recently obtained in the investigation of this proposal by applying techniques of abstract algebraic logic in the framework of Łukasiewicz logics and in the broader framework of substructural logics, that is, logics defined by varieties of (commutative and integral) residuated lattices. I also review some scattered, early results, which have appeared since the 1970’s, and make some proposals for further research. Keywords: many-valued logic, mathematical fuzzy logic, truth val- ues, truth degrees, logics preserving degrees of truth, residuated lattices, substructural logics, abstract algebraic logic, Leibniz hierarchy, Frege hierarchy.

  • Applications of Non-Classical Logic Andrew Tedder University of Connecticut - Storrs, [email protected]
    University of Connecticut OpenCommons@UConn Doctoral Dissertations University of Connecticut Graduate School 8-8-2018 Applications of Non-Classical Logic Andrew Tedder University of Connecticut - Storrs, [email protected] Follow this and additional works at: https://opencommons.uconn.edu/dissertations Recommended Citation Tedder, Andrew, "Applications of Non-Classical Logic" (2018). Doctoral Dissertations. 1930. https://opencommons.uconn.edu/dissertations/1930 Applications of Non-Classical Logic Andrew Tedder University of Connecticut, 2018 ABSTRACT This dissertation is composed of three projects applying non-classical logic to problems in history of philosophy and philosophy of logic. The main component concerns Descartes’ Creation Doctrine (CD) – the doctrine that while truths concerning the essences of objects (eternal truths) are necessary, God had vol- untary control over their creation, and thus could have made them false. First, I show a flaw in a standard argument for two interpretations of CD. This argument, stated in terms of non-normal modal logics, involves a set of premises which lead to a conclusion which Descartes explicitly rejects. Following this, I develop a multimodal account of CD, ac- cording to which Descartes is committed to two kinds of modality, and that the apparent contradiction resulting from CD is the result of an ambiguity. Finally, I begin to develop two modal logics capturing the key ideas in the multi-modal interpretation, and provide some metatheoretic results concerning these logics which shore up some of my interpretive claims. The second component is a project concerning the Channel Theoretic interpretation of the ternary relation semantics of relevant and substructural logics. Following Barwise, I de- velop a representation of Channel Composition, and prove that extending the implication- conjunction fragment of B by composite channels is conservative.

They expand on the work of Wilhelm Ackermann who, in 1956, published work on a theory of strengen Implikation. Relevance logic has grown into a rich and fascinating discipline. It has been mainly worked on by Australians and Americans, each working in their own style (Americans preferring many-valued world semantics, Australians two-valued world semantics).

  • The Systems of Relevance Logic
    ARGUMENT Vol. 1 1/2011 pp. 87–102 The Systems of Relevance Logic Ryszard MIREK Kraków ABSTRACT The system R, or more precisely the pure implicational fragment R →, is considered by the relevance logicians as the most important. The another central system of relevance logic has been the logic E of entailment that was supposed to capture strict relevant implication. The next system of relevance logic is RM or R-mingle. The question is whether adding mingle axiom to R → yields the pure implicational fragment RM → of the system? As concerns the weak systems there are at least two approaches to the problem. First of all, it is possible to restrict a validity of some theorems. In another approach we can investigate even weaker log- ics which have no theorems and are characterized only by rules of deducibility. 1. ThE SySTEM oF NATURAl DEDUCTIoN The central point of relevant logicians has been to avoid the paradoxes of material and strict implication. In other words, according to them, the heart of logic lies in the notion “if […] then [...]”. Among the material paradoxes the following are known: M1. α → (β → α) (positive paradox); M2. ~ α → (α → β); M3. (α → β) ∨ (β → α); M4. (α → β) ∨ (β → γ). In turn, among the strict paradoxes there are known the following: S1. α → (β → β); S2. α → (β ∨ ~ β); S3. (α ∧ ¬ α) → β (ex falso quodlibet). www.argument-journal.eu 88 Ryszard MIREK Relevance logicians have claimed that these theses are counterintui- tive. According to them, in each of them the antecedent seems irrelevant to the consequent.

  • Some Remarks on the Validity of the Principle of Explosion in Intuitionistic Logic1
    Some remarks on the validity of the principle of explosion in intuitionistic logic1 Edgar Campos2 & Abilio Rodrigues3 Abstract The formal system proposed by Heyting (1930, 1936) became the stan- dard formulation of intuitionistic logic. The inference called ex falso quodlibet, or principle of explosion, according to which anything follows from a contradiction, holds in intuitionistic logic. However, it is not clear that explosion is in accordance with Brouwer’s views on the nature of mathematics and its relationship with logic. Indeed, van Atten (2009) argues that a formal system in line with Brouwer’s ideas should be a relevance logic. We agree that explosion should not hold in intuitionistic logic, but a relevance logic requires more than the invalidity of explosion. The principle known as ex quodlibet verum, according to which a valid formula follows from anything, should also be rejected by a relevantist. Given ex quodlibet verum, the inference we call weak explosion, accord- ing to which any negated proposition follows from a contradiction, is proved in a few steps. Although the same argument against explosion can be also applied against weak explosion, rejecting the latter requires the rejection of ex quodlibet verum. The result is the loss of at least one among reflexivity, monotonicity, and the deduction theorem in a Brouwerian intuitionistic logic, which seems to be an undesirable result. 1. Introduction: Brouwer on mathematics and logic The main divergence between Brouwer and the standard approach to mathematics, based on classical logic, is his understanding of the notions of existence and truth as applied to mathematics. According to Brouwer, “to exist in mathematics means: to be constructed by intuition” (Brouwer, 1907, p.

  • J. Michael Dunn and Greg Restall
    J. MICHAEL DUNN AND GREG RESTALL RELEVANCE LOGIC 1 INTRODUCTION 1.1 Delimiting the topic The title of this piece is not `A Survey of Relevance Logic'. Such a project was impossible in the mid 1980s when the first version of this article was published, due to the development of the field and even the space limitations of the Handbook. The situation is if anything, more difficult now. For example Anderson and Belnap and Dunn's two volume [1975, 1992] work Entailment: The Logic of Relevance and Necessity, runs to over 1200 pages, and is their summary of just some of the work done by them and their co- workers up to about the late 1980s. Further, the comprehensive bibliography (prepared by R. G. Wolf) contains over 3000 entries in work on relevance logic and related fields. So, we need some way of delimiting our topic. To be honest the fact that we are writing this is already a kind of delimitation. It is natural that you shall find emphasised here the work that we happen to know best. But still rationality demands a less subjective rationale, and so we will proceed as follows. Anderson [1963] set forth some open problems for his and Belnap's sys- tem E that have given shape to much of the subsequent research in relevance logic (even much of the earlier work can be seen as related to these open problems, e.g. by giving rise to them). Anderson picks three of these prob- lems as major: (1) the admissibility of Ackermann's rule γ (the reader should not worry that he is expected to already know what this means), (2) the decision problems, (3) the providing of a semantics.
