  1. In Contradiction: A Study of the Transconsistent.Graham Priest - 1987 - Dordrecht, Netherland: Oxford University Press.
    In Contradiction advocates and defends the view that there are true contradictions, a view that flies in the face of orthodoxy in Western philosophy since Aristotle. The book has been at the center of the controversies surrounding dialetheism ever since its first publication in 1987. This second edition of the book substantially expands upon the original in various ways, and also contains the author’s reflections on developments over the last two decades. Further aspects of dialetheism are discussed in the (...)

  3. Contradictions at the borders.David Ripley - 2011 - In Rick Nouwen, Robert van Rooij, Uli Sauerland & Hans-Christian Schmitz (eds.), Vagueness in Communication. Springer. pp. 169--188.
    The purpose of this essay is to shed some light on a certain type of sentence, which I call a borderline contradiction. A borderline contradiction is a sentence of the form F a ∧ ¬F a, for some vague predicate F and some borderline case a of F , or a sentence equivalent to such a sentence. For example, if Jackie is a borderline case of ‘rich’, then ‘Jackie is rich and Jackie isn’t rich’ is a borderline (...). Many theories of vague language have entailments about borderline contradictions; correctly describing the behavior of borderline contradictions is one of the many tasks facing anyone offering a theory of vague language. Here, I first briefly review claims made by various theorists about these borderline contradictions, attempting to draw out some predictions about the behavior of ordinary speakers. Second, I present an experiment intended to gather relevant data about the behavior of ordinary speakers. Finally, I discuss the experimental results in light of several different theories of vagueness, to see what explanations are available. My conclusions are necessarily tentative; I do not attempt to use the present experiment to demonstrate that any single theory is incontrovertibly true. Rather, I try to sketch the auxiliary hypotheses that would need to be conjoined to several extant theories of vague language to predict the present result, and offer some considerations regarding the plausibility of these various hypotheses. In the end, I conclude that two of the theories I consider are better-positioned to account for the observed data than are the others. But the field of logically-informed research on people’s actual responses to vague predicates is young; surely as more data come in we will learn a great deal more about which (if any) of these theories best accounts for the behavior of ordinary speakers.

  4. Contradiction and Kant’s Formula of Universal Law.Pauline Kleingeld - 2017 - Kant Studien 108 (1):89-115.
    Kant’s most prominent formulation of the Categorical Imperative, known as the Formula of Universal Law (FUL), is generally thought to demand that one act only on maxims that one can will as universal laws without this generating a contradiction. Kant's view is standardly summarized as requiring the 'universalizability' of one's maxims and described in terms of the distinction between 'contradictions in conception' and 'contradictions in the will'. Focusing on the underappreciated significance of the simultaneity condition included in the FUL, (...)

    Contradiction, Quantum Mechanics, and the Square of Opposition.Jonas R. B. Arenhart & Décio Krause - unknown
    We discuss the idea that superpositions in quantum mechanics may involve contradictions or contradictory properties. A state of superposition such as the one comprised in the famous Schrödinger’s cat, for instance, is sometimes said to attribute contradictory properties to the cat: being dead and alive at the same time. If that were the case, we would be facing a revolution in logic and science, since we would have one of our greatest scientific achievements showing that real contradictions exist.We analyze that (...)

    The Contradictions of Modern Moral Philosophy: Ethics After Wittgenstein.Dr Paul Johnston & Paul Johnston - 1999 - Routledge.
    _The Contradictions of Modern Moral Philosophy_ is a highly original and radical critique of contemporary moral theory. Paul Johnston demonstrates that much recent moral philosophy is confused about the fundamental issue of whether there are correct moral judgements. He shows that the standard modern approaches to ethics cannot justify - or even make much sense of - traditional moral beliefs. Applied rigorously, these approaches suggest that we should reject ethics as a set of outdated and misguided claims. Rather than facing (...)

    Hyper-contradictions, generalized truth values and logics of truth and falsehood.Yaroslav Shramko & Heinrich Wansing - 2006 - Journal of Logic, Language and Information 15 (4):403-424.
    In Philosophical Logic, the Liar Paradox has been used to motivate the introduction of both truth value gaps and truth value gluts. Moreover, in the light of “revenge Liar” arguments, also higher-order combinations of generalized truth values have been suggested to account for so-called hyper-contradictions. In the present paper, Graham Priest's treatment of generalized truth values is scrutinized and compared with another strategy of generalizing the set of classical truth values and defining an entailment relation on the resulting sets of (...)

    Contradictions, from Consistency to Inconsistency (Trends in Logic 47, Springer International Publishing, 2018, VI+322 pages). [REVIEW]Rafael R. Testa - 2019 - Manuscrito 42 (1):219-228.
    In this review I briefly analyse the main elements of each chapter of the book centred in the general areas of logic, epistemology, philosophy and history of science. Most of them are developed around a fine-grained investigation on the principle of non-contradiction and the concept of consistency, inquired mainly into the broad area of paraconsistent logics. The book itself is the result of a work that was initiated on the Studia Logica conference "Trends in Logic XVI: Consistency, Contradiction, (...)

  11. The Law of Non-Contradiction : New Philosophical Essays.Graham Priest, Jc Beall & Bradley P. Armour-Garb (eds.) - 2004 - Oxford, England: Oxford University Press.
    The Law of Non-Contradiction - that no contradiction can be true - has been a seemingly unassailable dogma since the work of Aristotle, in Book G of the Metaphysics. It is an assumption challenged from a variety of angles in this collection of original papers. Twenty-three of the world's leading experts investigate the 'law', considering arguments for and against it and discussing methodological issues that arise whenever we question the legitimacy of logical principles. The result is a balanced (...)

    Paraconsistent Logic: Consistency, Contradiction and Negation.Walter Carnielli & Marcelo Esteban Coniglio - 2016 - Basel, Switzerland: Springer International Publishing.
    This book is the first in the field of paraconsistency to offer a comprehensive overview of the subject, including connections to other logics and applications in information processing, linguistics, reasoning and argumentation, and philosophy of science. It is recommended reading for anyone interested in the question of reasoning and argumentation in the presence of contradictions, in semantics, in the paradoxes of set theory and in the puzzling properties of negation in logic programming. Paraconsistent logic comprises a major logical theory and (...)
  13. Acceptable Contradictions: Pragmatics or Semantics? A Reply to Cobreros et al. [REVIEW]Sam Alxatib, Peter Pagin & Uli Sauerland - 2013 - Journal of Philosophical Logic 42 (4):619-634.
    Naive speakers find some logical contradictions acceptable, specifically borderline contradictions involving vague predicates such as Joe is and isn’t tall. In a recent paper, Cobreros et al. (J Philos Logic, 2012) suggest a pragmatic account of the acceptability of borderline contradictions. We show, however, that the pragmatic account predicts the wrong truth conditions for some examples with disjunction. As a remedy, we propose a semantic analysis instead. The analysis is close to a variant of fuzzy logic, but conjunction and disjunction (...)

    Contradictions: Logic, History, Actuality.Elena Ficara (ed.) - 2014 - Boston: De Gruyter.
    The papers in this volume present some of the most recent results of the work about contradictions in philosophical logic and metaphysics; examine the history of contradiction in crucial phases of philosophical thought; consider the relevance of contradictions for political and philosophical actuality. From this consideration a common question emerges: the question of the irreducibility, reality and productive force of (some) contradictions.

  18. A Contradiction of the Right Kind: Convenience Killing and Kant’s Formula of Universal Law.Pauline Kleingeld - 2019 - Philosophical Quarterly 69 (274):64-81.
    One of the most important difficulties facing Kant’s Formula of Universal Law (FUL) is its apparent inability to show that it is always impermissible to kill others for the sake of convenience. This difficulty has led current Kantian ethicists to de-emphasize the FUL or at least complement it with other Kantian principles when dealing with murder. The difficulty stems from the fact that the maxim of convenience killing fails to generate a ‘contradiction in conception’, producing only a ‘contradiction (...)

    Although it is not younger than other areas of non-classical logic, paraconsistent logic has received full recognition only in recent years, largely due to the work of, among others, Newton da Costa, Graham Priest, Diderik Batens, and Jerzy Perzanowski. A logical system Λ is paraconsistent if there is a set of Λ-formulas Δ ∪ {A} such that in Λ one may derive from Δ both A and its negation, and the deductive closure of Δ with respect to Λ is different (...)

    Disentangling Contradiction from Contrariety via Incompatibility.Jean-Yves Beziau - 2016 - Logica Universalis 10 (2-3):157-170.
    Contradiction is often confused with contrariety. We propose to disentangle contrariety from contradiction using the hexagon of opposition, providing a clear and distinct characterization of three notions: contrariety, contradiction, incompatibility. At the same time, this hexagonal structure describes and explains the relations between them.

    The Law of Non-Contradiction holds that both sides of a contradiction cannot be true. Dialetheism is the view that there are contradictions both sides of which are true. Crucial to the dispute, then, is the central notion of contradiction. My first step here is to work toward clarification of that simple and central notion: Just what is a contradiction?

    In In Contradiction, Graham Priest shows, as clearly as anything like this can be shown, that it is coherent to maintain that some sentences can be both true and false at the same time. As a consequence, some contradictions are true, and an appreciation of this possibility advances our understanding of the nature of logic and language.

  24. Dialectical Contradictions and Classical Formal Logic.Inoue Kazumi - 2014 - International Studies in the Philosophy of Science 28 (2):113-132.
    A dialectical contradiction can be appropriately described within the framework of classical formal logic. It is in harmony with the law of noncontradiction. According to our definition, two theories make up a dialectical contradiction if each of them is consistent and their union is inconsistent. It can happen that each of these two theories has an intended model. Plenty of examples are to be found in the history of science.

However, things have recently changed, and nowadays various philosophers, called dialetheists, claim that this Law does (...)

    Contradiction in Buddhist Argumentation.Mark Siderits - 2008 - Argumentation 22 (1):125-133.
    Certain Buddhist texts contain statements that are prima facie contradictions. The scholarly consensus has been that such statements are meant to serve a rhetorical function that depends on the apparent contradictions being resolvable. But recently it has been claimed that such statements are meant to be taken literally: their authors assert as true statements that are of the form ‘p and not p’. This claim has ramifications for our understanding of the role played by the principle of non-contradiction in (...)

    Is there a notion of contradiction—let us call it, for dramatic effect, “absolute”—making all contradictions, so understood, unacceptable also for dialetheists? It is argued in this paper that there is, and that spelling it out brings some theoretical benefits. First it gives us a foothold on undisputed ground in the methodologically difficult debate on dialetheism. Second, we can use it to express, without begging questions, the disagreement between dialetheists and their rivals on the nature of truth. Third, dialetheism has (...)

    Are Contradictions Believable?Yale Weiss - 2019 - Thought: A Journal of Philosophy 8 (1):42-49.
    A number of philosophers deny that contradictions can be believed. Are they correct? In this note, I show that even in quite weak logics, on pain of inconsistency, if there are false beliefs, either there are propositions which are true but unbelievable or contradictions are believable. Since the antecedent clearly holds, I offer some considerations in favor of the latter disjunct. Objections and variants of the main argument are considered.

    Epistemic Contradictions Do Not Threaten Classical Logic.Philipp Mayr - 2022 - Acta Analytica 37 (4):551-573.
    Epistemic contradictions are now a well-known and often discussed phenomenon among those who study epistemic modals. These contradictions are expressed by sentences like ‘It is raining and it might not be raining’ whose oddness to the common ear demands an explanation. However, it has turned out to be a rather controversial enterprise to provide such an explanation in a sufficiently precise and general manner. According to pragmatic explanations, epistemic contradictions are semantically consistent but pragmatically defective. According to semantic explanations, one (...)

    Transhumanism, the belief that technology can transcend the limitations of the human body and brain, is part of the family of Enlightenment philosophies. As such, transhumanism has also inherited the internal tensions and contradictions of the broad Enlightenment tradition. First, the project of Reason is self-erosive and requires irrational validation. Second, although most transhumanists are atheist, their belief in the transcendent power of intelligence generates new theologies. Third, although most transhumanists are liberal democrats, their belief in human perfectibility and governance (...)

    Non-contradiction: Oh Yeah and So What?Mark T. Nelson - 2013 - Think 12 (34):87-91.
    The logical Law of Non-contradiction – that a proposition cannot be both true and false – enjoys a special, perhaps uniquely privileged, status in philosophy. Most philosophers think that finding a contradiction – the assertion of both P and not-P – in one's reasoning is the best possible evidence that something has gone wrong, the ultimate refutation of a position. But why should this be so? What reason do we have to believe it? In this paper, I address (...)

    Contradiction and the Instant of Change Revisited.Graham Priest - 2017 - Vivarium 55 (1-3):217-226.
    Instantaneous changes may well be thought to give rise to contradiction. If one endorses an explosive logic, where contradictions entail everything, this is entirely unacceptable. However, if one deploys a paraconsistent logic, which keeps contradictions under control, one may give perfectly coherent and precise models of such changes. In In Contradiction the author showed how and he explored the philosophical implications of the model. Here, the author revisits the issue in the light of a recent critique by Greg (...)

    This essay argues that we should find Crimmigration, which is the collapsing of immigration law with criminal law, morally problematic for three reasons. First, it denies those who are facing criminal penalties important constitutional protections. Second, it doubly punishes those who have already served their criminal sentence with an added punishment that should be considered cruel and unusual (i.e., indefinite imprisonment or exile). Third, when the tactics aimed at protecting and serving local communities get usurped by the federal government for (...)

  44. Contradiction, Coherence, and Guided Discretion in the Supreme Court's Capital Sentencing Jurisprudence.Mary Sigler - 2003 - Dissertation, Arizona State University
    This project explores the "contradiction" that critics contend lies at the heart of the Supreme Court's capital sentencing jurisprudence. The doctrine of "guided discretion," represents the Court's attempt to achieve both consistency and individuation in capital sentencing. Guided discretion rejects the unbridled sentencing discretion of an earlier era that resulted in sentencing decisions that were "arbitrary and capricious." At the same time, guided discretion requires juries to give individualized consideration to the facts and circumstances of individual defendants. Critics contend (...)

  45. The Contradictions of Libertarianism.Joseph Grcic - 2011 - Etica E Politica 13 (2):365-382.
    Libertarianism is an ideology which reveals its contradictions when it is implemented. The libertarian denial of the right to what Rawls calls fair quality of opportunity, especially to the right to education, would negatively impact any libertarian society in adapting to its environment. Further, a libertarian society would lead to a caste society and the domination of the political system by an elite primarily interested in protecting its own privileges, not the freedom of the masses.

    Belief, Contradiction and the Logic of Self-Deception.Newton C. A. da Costa & Steven French - 1990 - American Philosophical Quarterly 27 (3):179 - 197.
    The apparently paradoxical nature of self-deception has attracted a great deal of controversy in recent years. Focussing on those aspects of the phenomenon which involve the holding of "contradictory" beliefs, it is our intention to argue that this presents no "paradox" if a non-classical, "paraconsistent", doxastic logic is adopted. (On such logics, see, for example, N. C. A. da Costa, 'On the theory of inconsistent formal systems', Notre Dame J Formal Logic 11(1974), 497-510, and A. I. Arruda, 'A survey of (...)

    In this paper we discuss Priest’s account of change and motion, contrasting it with its more orthodox rival, the Russellian account. The paper is divided in two parts. In first one we take a stance that is more sympathetic to the Russellian view, arguing that Priest’s arguments against it are inconclusive. In the second part, instead, we take a more sympathetic attitude towards Priest’s objections. We argue, however, that if these objections pose insurmountable difficulties to the Russellian account, then they (...)
