What I am calling for is not as radically new as it may sound to ears that are still tuned to positivist frequencies. A very large part of what we value as our cultural monuments can be thought of as metaphoric criticism of metaphor and the characters who make them. The point is perhaps most easily made about the major philosophies. Stephen Pepper has argued, in World Hypotheses,1 that the great philosophies all depend on one of the four "root metaphors," (...) formism, mechanism, organicism, and contextualism, and they are great precisely because they have so far survived the criticism of rival metaphors. Each view of the totality of things claims supremacy, but none has been able to annihilate the others. They all thus survive as still plausible, pending further criticism through further philosophical inquiry. In this view, even the great would-be literalists like Hobbes and Locke are finally metaphorists—simply committed to another kind of metaphor, one that to them seems literal. Without grossly oversimplifying we could say that the whole work of each philosopher amounts to an elaborate critique of the inadequacy of all other philosophers' metaphors. What is more, the very existence of a tradition of a small group of great philosophies is a sign that hundreds of lesser metaphors for the life of mankind have been tested in the great philosophical—that is, critical—wars and found wanting. · 1.

Orthologic is defined by weakening the axioms and rules of inference of the classical propositional calculus. The resulting Lindenbaum-Tarski quotient algebra is an orthoimplication algebra which generalizes the author's implication algebra. The associated order structure is a semi-orthomodular lattice. The theory of orthomodular lattices is obtained by adjoining a falsity symbol to the underlying orthologic or a least element to the orthoimplication algebra.

Napolitano (The epistemology of fake news, Oxford University Press, 2021) argues that the Minimalist Account of conspiracy theories—i.e., which defines conspiracy theories as explanations, or theories, about conspiracies—should be rejected. Instead, she proposes to define conspiracy theories as a certain kind of belief—i.e., an evidentially self-insulated belief in a conspiracy. Napolitano argues that her account should be favored over the Minimalist Account based on two considerations: ordinary language intuitions and theoretical fruitfulness. I show how Napolitano’s account fails its own purposes (...) with respect to these two considerations and so should not be favored over the Minimalist Account. Furthermore, I propose that the Minimalist Account is the best conception of ‘conspiracy theory’ if we share Napolitano’s goal of advancing the understanding of conspiracy theories. (shrink)

In Spandrels of Truth, Beall concisely presents and defends a modest, so-called dialetheic theory of transparent truth.

Consequence is at the heart of logic, and an account of consequence offers a vital tool in the evaluation of arguments. This text presents what the authors term as 'logical pluralism' arguing that the notion of logical consequence doesn't pin down one deductive consequence relation; it allows for many of them.

A good argument is one whose conclusions follow from its premises; its conclusions are consequences of its premises. But in what sense do conclusions follow from premises? What is it for a conclusion to be a consequence of premises? Those questions, in many respects, are at the heart of logic (as a philosophical discipline). Consider the following argument: 1. If we charge high fees for university, only the rich will enroll. We charge high fees for university. Therefore, only the rich (...) will enroll. There are many different things one can say about this argument, but many agree that if we do not equivocate (if the terms mean the same thing in the premises and the conclusion) then the argument is valid, that is, the conclusion follows deductively from the premises. This does not mean that the conclusion is true. Perhaps the premises are not true. However, if the premises are true, then the conclusion is also true, as a matter of logic. This entry is about the relation between premises and conclusions in valid arguments. (shrink)

Las reflexiones recogidas en este volumen constituyeron, en su mayor parte, el contenido del Seminario de Semántica celebrado en la Universidad de Oviedo, y uno de los textos ("Léxico y cognición: ¿hay términos de base?") formó parte del programa de conferencias de Año Europeo de las Lenguas. Conforme al espíritu de esas jornadas centradas en la pluralidad lingüística, esta publicación se hace simultáneamente en dos lenguas: español y francés. Aunque se tomen como referencia aspectos concretos de dos lenguas concretas, la (...) española y la francesa, los problemas que aquí se suscitan son de índole general, ya que afectan, y de manera crucial, a todas las lenguas.

The Liar paradox raises foundational questions about logic, language, and truth (and semantic notions in general). A simple Liar sentence like 'This sentence is false' appears to be both true and false if it is either true or false. For if the sentence is true, then what it says is the case; but what it says is that it is false, hence it must be false. On the other hand, if the statement is false, then it is true, since it (...) says (only) that it is false. -/- How, then, should we classify Liar sentences? Are they true or false? A natural suggestion would be that Liars are neither true nor false; that is, they fall into a category beyond truth and falsity. This solution might resolve the initial problem, but it beckons the Liar's revenge. A sentence that says of itself only that it is false or beyond truth and falsity will, in effect, bring back the initial problem. The Liar's revenge is a witness to the hydra-like nature of Liars: in dealing with one Liar you often bring about another. -/- JC Beall presents fourteen new essays and an extensive introduction, which examine the nature of the Liar paradox and its resistance to any attempt to solve it. Written by some of the world's leading experts in the field, the papers in this volume will be an important resource for those working in truth studies, philosophical logic, and philosophy of language, as well as those with an interest in formal semantics and metaphysics.

The paper reviews a number of approaches for handling restricted quantification in relevant logic, and proposes a novel one. This proceeds by introducing a novel kind of enthymematic conditional.

At first thought, our question of the day seems to be "about the text itself." Is there, in all texts, or at least in some texts, what Abrams calls "a core of determinate meanings," "the central core of what they [the authors] undertook to communicate"? Miller has seemed to find in the texts of Nietzsche a claim that there is not, that "the same text authorizes innumerable interpretations: There is no 'correct' interpretation. . . . reading is never the objective (...) identifying of a sense but the importation of meaning into a text which has no meaning 'in itself.'" Abrams claims that Miller cannot report on Nietzsche's deconstructionist claims without violating them: Miller seems to claim that he has found something that Nietzsche's text really says, not something that Miller himself merely brought to it. Is this objection a quibble or a clincher?1 · 1. See my "M.H. Abrams: Historian as Critic, Critic as Pluralist," Critical Inquiry 2 : 411-45, and Abrams' reply, "Rationality and Imagination in Cultural History," pp. 447-64, esp. 456-58. Wayne C. Booth's other contributions to Critical Inquiry include "Kenneth Burke's Way of Knowing" , "Irony and Pity Once Again: Thais Revisited" , "Notes and Exchanges" , "Metaphor as Rhetoric: The Problem of Evaluation" ,"Ten Literal 'Theses" , with Wright Morris: "The Writing of Organic Fiction: A Conversation" , and with Robert E.

In his book The Austrian Mind (1972) W. M. Johnston observes that between 1861 and 1938 a striking number of Austrian intellectuals committed uicide. He also remarks that prior to 1920 suicide was relatively rare among Hungarian intellectuals, and as a possible explanation he refers to their more intensive political activity. The present paper investigates relations between a society's intellectual life and its general suicidal tendencies. In so doing it takes up a central theme of T. G. Masaryk's Suicide as (...) a Social Mass Phenomenon of Modern Civilization, published in Vienna in 1881. (shrink)

Extensively classroom-tested, Possibilities and Paradox provides an accessible and carefully structured introduction to modal and many-valued logic. The authors cover the basic formal frameworks, enlivening the discussion of these different systems of logic by considering their philosophical motivations and implications. Easily accessible to students with no background in the subject, the text features innovative learning aids in each chapter, including exercises that provide hands-on experience, examples that demonstrate the application of concepts, and guides to further reading.

This book is available either individually, or as part of the specially-priced Arguments of the Philosphers Collection.

Semantic and soritical paradoxes challenge entrenched, fundamental principles about language - principles about truth, denotation, quantification, and, among others, 'tolerance'. Study of the paradoxes helps us determine which logical principles are correct. So it is that they serve not only as a topic of philosophical inquiry but also as a constraint on such inquiry: they often dictate the semantic and logical limits of discourse in general. Sixteen specially written essays by leading figures in the field offer new thoughts and arguments (...) about the paradoxes. (shrink)

The dominating theologian in Europe between Thomas Aquinas and John Duns Scotus, Henry of Ghent produced a massive Summa of Ordinary Questions as well as fifteen quodlibets during his long tenure at the University of Paris. His work constituted a new synthesis of faith and reason which competed with that of Thomas Aquinas and influenced the history of both philosophy and theology. The first five articles of the Summa, dealing with various issues associated with human knowledge, constitute an adequate introduction (...) to Henry's thought. In them we find his approach to fundamental principles and themes developed in detail in the rest of his corpus. Of the five, only article one has appeared as a whole in English translation. The next four articles reinforce and develop the findings of the first article, providing additional treatments that indicate Henry's principles and orientation. In fact, these four articles alone provide a condensed but remarkably rich portrait of Henry's basic thought, and so are an invaluable resource for beginning and advanced students alike. Articles 2-5 include important positions on knowledge and reality, a conception of humanity's ultimate purpose and the pursuits most conducive to it, and an approach to faith and reason. These four articles are presented here for the first time in English translation with an introduction and notes. Along with the translation, the volume includes the Latin text of the modern critical edition. --Book cover. (shrink)

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 consequence 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.
