  • Project Abstract the Summer Program for Diversity in Logic for Undergraduates Builds Upon the PIKSI Summer Program Model, Focusi
    Project Abstract The Summer Program for Diversity in Logic for Undergraduates builds upon the PIKSI Summer Program Model, focusing on Logic, an area in philosophy needing to increase diversity. We request seed funding for the pilot run of the program in May of 2016, when we will offer 12 students the opportunity to explore an exciting research theme in Logic –Paradoxes—receive small-group tutoring in formal techniques, receive mentoring and support for professionalization, experience validation, understanding and advice regarding diversity issues they have encountered –sexism, racism, ableism (and which the students may worry about encountering them in the profession), and develop a sense of community with students and faculty with whom they can identify and, in turn, come to strengthen their own identities. Project Purpose Our goal is to empower students to conceive of themselves as aspiring logicians, philosophers of logic and formal philosophers who belong in our profession. As Audrey Yap has noted, a majority of philosophy majors encounter some logic as a part of their undergraduate curriculum. Increasing diversity in logic is not simply a problem of exposure, but concretely addressing underlying pressures women and minority students experience, particularly stereotype threat and pernicious ideas about “natural aptitude.” (1) These pressures are especially strong in the subfield of logic, where almost no women and minorities have contributed to the research literature until very recently, and women and minorities remain underrepresented to a higher degree than in philosophy more broadly. Women and minorities learning logic can be vulnerable to feeling that a field like logic, that tends to be male and white dominated on the whole, is not welcoming to them.

  • Introduction: at the Intersection of Truth and Falsity
    Introduction: At the Intersection of Truth and Falsity JC Beall ‘Now we will take another line of reasoning. When you follow two separate chains of thought, Watson, you will find some point of intersection which should approximate to the truth.’—Sherlock Holmes, in ‘The Disappearance of Lady Frances Carfax’. 1. TOWARDS THE INTERSECTION Suppose that we have (at least) two categories X and Y for any meaningful, declarative sentence A of our language.É Pending further information about X and Y, there seem to be four options for an arbitrary sentence A: » A is only in X » A is only in Y » A is in both X and Y » A is in neither X nor Y Whether each such ‘option’ is logically possible depends not only on our logic (about which more below) but on the details of X and Y. Suppose that X comprises all (and only) sentences composed of exactly six words, and Y those with exactly nineteen words. In that case, only the third option is ruled out: X and Y are exclusive—their intersection X ∩ Y is empty—since no A can be composed of exactly six words and also be composed of exactly nineteen words.Ê Despite being exclusive, X and Y are not exhaustive—their union X ∪ Y does not exhaust all sentences—since some A may fall into neither X nor Y. (Just consider ‘Max sat on Agnes’.) Consider another example. Let X comprise all sentences of your favourite novel and Y your all-time favourite sentences. In that case, exclusion is not ruled out; the intersection of X and Y may well be non-empty.

  • Defending Logical Pluralism
    Defending Logical Pluralism .................................................................... JC Beall Greg Restall School of Philosophy Department of Philosophy University of Tasmania Macquarie University .................................................................... Version of May 17, 1999 1 Introducing Logical Pluralism We are pluralists about logical consequence [1]. We hold that there is more than one sense in which arguments may be deductively valid, that these senses are equally good, and equally deserving of the name deductive validity. Our pluralism starts with our analysis of consequence. This analysis of con- sequence is not idiosyncratic. We agree with Richard Jeffrey, and with many other philosophers of logic about how logical consequence is to be defined. To quote Jeffrey: Formal logic is the science of deduction. It aims to provide system- atic means for telling whether or not given conclusions follow from given premises, i.e., whether arguments are valid or invalid . Validity is easily defined: A valid argument is one whose conclusion is true in every case in which all its premises are true. Then the mark of validity is absence of counterexamples, cases in which all premises are true but the conclusion is false. Difficulties in applying this definition arise from difficulties in can- vassingthecasesmentionedinit...[6,page1] We agree that deductive validity is a matter of the preservation of truth in all cases. An argument is valid when there is no counterexample to it: that is, there is no case in which the premises are true and in which the conclusion is not true. We call this account of validity (V) for short. Our pluralism stems from the difficulties to which Jeffrey alludes. We hold that there is more than one notion of case which may be substituted (correctly) into the defining scheme for validity.

  • HISTORY of LOGICAL CONSEQUENCE 1. Introduction
    HISTORY OF LOGICAL CONSEQUENCE CONRAD ASMUS AND GREG RESTALL 1. Introduction Consequence is a, if not the, core subject matter of logic. Aristotle's study of the syllogism instigated the task of categorising arguments into the logically good and the logically bad; the task remains an essential element of the study of logic. In a logically good argument, the conclusion follows validly from the premises; thus, the study of consequence and the study of validity are the same. In what follows, we will engage with a variety of approaches to consequence. The following neutral framework will enhance the discussion of this wide range of approaches. Consequences are conclusions of valid arguments. Arguments have two parts: a conclusion and a collection of premises. The conclusion and the premises are all entities of the same sort. We will call the conclusion and premises of an argument the argument's components and will refer to anything that can be an argument component as a proposition. The class of propositions is defined func- tionally (they are the entities which play the functional role of argument compo- nents); thus, the label should be interpreted as metaphysically neutral. Given the platonistic baggage often associated with the label \proposition", this may seem a strange choice but the label is already used for the argument components of many of the approaches below (discussions of Aristotlean and Medieval logic are two ex- amples). A consequence relation is a relation between collections of premises and conclusions; a collection of premises is related to a conclusion if and only if the latter is a consequence of the former.

  • Pluralism.Pdf
    Logical Pluralism ...................................................... JC Beall and Greg Restall Version of March 28, 2000 Abstract: A widespread assumption in contemporary philosophy of logic is that there is one true logic, that there is one and only one correct answer as to whether a given argument is deductively valid. In this paper we propose an alternative view, logical pluralism. According to logical pluralism there is not one true logic; there are many. There is not always a single answer to the question “is this argument valid?” 1 Logic, Logics and Consequence Anyone acquainted with contemporary Logic knows that there are many so-called logics.1 But are these logics rightly so-called? Are any of the menagerie of non-classical logics, such as relevant logics, intuitionistic logic, paraconsistent logics or quantum logics, as deserving of the title ‘logic’ as classical logic? On the other hand, is classical logic really as de- serving of the title ‘logic’ as relevant logic (or any of the other non-classical logics)? If so, why so? If not, why not? Logic has a chief subject matter: Logical Consequence. The chief aim of logic is to account for consequence — to say, accurately and systematically, what consequence amounts to, which is normally done by specifying which arguments (in a given language) are valid. All of this, at least today, is common ground. Logic has not always been seen in this light. Years ago, Logic was dom- inated by the Frege–Russell picture which treats logical truth as the lead character and consequence as secondary. The contemporary picture re- verses the cast: consequence is the lead character.

  • Greg Restall Is Associate Professor in Philosophy at Melbourne University, Australia
    Logic Logic is a comprehensive introduction to the major concepts and techniques involved in the study of logic. It explores both formal and philosophical logic and examines the ways in which we can achieve good reasoning. The methods of logic are essential to an understanding of philosophy and are also crucial in the study of mathematics, computing, linguistics and in many other domains. Individual chapters include: • Propositions and arguments • Truth tables • Trees • Conditionality • Natural deduction • Predicate, names and quantifiers • Definite descriptions Logic is an exceptionally clear introduction to the subject and is ideally suited to students taking an introductory course in logic. Greg Restall is Associate Professor in Philosophy at Melbourne University, Australia. Fundamentals of Philosophy Series editor: John Shand This series presents an up-to-date set of engrossing, accurate and lively introductions to all the core areas of philosophy. Each volume is written by an enthusiastic and knowledgeable teacher of the area in question. Care has been taken to produce works that while even-handed are not mere bland expositions, and as such are original pieces of philosophy in their own right. The reader should not only be well informed by the series, but also experience the intellectual excitement of being engaged in philosophical debate itself. The volumes serve as an essential basis for the under-graduate courses to which they relate, as well as being accessible and absorbing for the general reader. Together they comprise an indispensable

  • Carnap's Tolerance, Language Change and Logical Pluralism
    Carnap's Tolerance, Language Change and Logical Pluralism GREG RESTALL∗ PHILOSOPHY DEPARTMENT, MACQUARIE UNIVERSITY [email protected] May 16, 2001 http://www.phil.mq.edu.au/staff/grestall/cv.html Abstract: In this paper, I distinguish different kinds of pluralism about logical conse- quence. In particular, I distinguish the pluralism about logic arising from Carnap's Principle of Tolerance from a pluralism which maintains that there are different, equally “good” logical consequence relations on the one language. I will argue that this sec- ond form of pluralism does more justice to the contemporary state of logical theory and practice than does Carnap's more moderate pluralism. 1 Pluralism about Logical Consequence With JC Beall, I have argued for and defended a very particular account of logical pluralism [5, 6]. We take it that the notion of logical consequence is ir- reducibly plural in its application. That is, we take it that there are at least two distinct relations of logical consequence — and not simply two distinct rela- tions in intension, but two distinct relations in extension. We take it that there are arguments which are valid according to one logic, and invalid according to another, and that there is no further fact of the matter as to whether the argu- ment is really valid. For the sake of this paper let me be quite specific. I will take two particular argument forms. First, the argument form I will call explosion: From A ^ ∼A to infer B. This argument form is valid classically, and invalid relevantly. Similarly, the argument form of disjunctive syllogism: From A _ B and ∼A to infer B is valid classically, and invalid relevantly [8].
