CONTRASTING PREJUDICES TRUTH AND FALSEHOOD How can one say something false? How can one even think such a thing? Since, for example, all men are mortal, ...

On the basis of careful textual exegesis and philosophical analysis, and contrary to the received view, Mark R. Wheeler demonstrates that Aristotle presents and systematically explicates his definition of the essence of the truth in the Metaphysics. Aristotle states the nominal definitions of the terms "truth" and "falsehood" as part of his arguments in defense of the logical axioms. These nominal definitions express conceptions of truth and falsehood his philosophical opponents would have recognized and accepted in the context (...) of dialectical argument. On the basis of these nominal definitions, Aristotle develops his definitions of the essences of truth and falsehood--his "real" definitions of truth and falsehood. Aristotle's methodical exposition of his essential definitions of truth and falsehood in the Metaphysics serves as a well-developed example of how his philosophical inquiry starts with nominal definitions and ends with real definitions. Wheeler also argues for the novel claim that Aristotle defines the most fundamental kind of truth in terms of accurate measurement. Aristotle's metrical conception of truth serves as the theoretical basis for specifying the truth conditions of various assertions, for identifying the sorts of beings implicated in these truth conditions, and for explaining the nature of approximate truth and falsehood. Far from offering us a minimal account of truth, Wheeler shows how Aristotle offers us a sophisticated and metrical theory of truth. (shrink)

Did archaic Greek poets think that speech should be factually informative? Studies in the "history of thought" suggest that archaic culture offered no developed alternative to the opposition of truth to falsehood judged in relationship to fact. But the mythic poems display more interest in person-to-person agreement than eye-to-object fidelity. This is seen in the numerous stories where partnerships are negotiated and symbolized through tokens whose impersonal value is flagrantly disregarded. In the Hymn to Hermes, facetious non-truths establish intimacy (...) and cooperation among those who understand them. (shrink)

The book presents a thoroughly elaborated logical theory of generalized truth-values understood as subsets of some established set of truth values. After elucidating the importance of the very notion of a truth value in logic and philosophy, we examine some possible ways of generalizing this notion. The useful four-valued logic of first-degree entailment by Nuel Belnap and the notion of a bilattice constitute the basis for further generalizations. By doing so we elaborate the idea of a multilattice, and most notably, (...) a trilattice of truth values – a specific algebraic structure with information ordering and two distinct logical orderings, one for truth and another for falsity. Each logical order not only induces its own logical vocabulary, but determines also its own entailment relation. We consider both semantic and syntactic ways of formalizing these relations and construct various logical calculi. (shrink)

Current epistemological dogma has it that the twin goalsof believing truths and avoiding errors exhaust our cognitive aspirations.On such a view, (call it the TG view) the only evaluationsthat count as genuinely epistemological are those that evaluatesomething (a belief, believer, set of beliefs, a cognitivetrait or process, etc.) in terms of its connection to thesetwo goods. In particular, this view implies that all theepistemic value of knowledge must be derived from thevalue of the two goals cited in TG. I argue (...) thatthis implication is false, and thus that the TG view must be abandoned. I propose a candidate to replacethe TG view that makes better sense of the value ofknowledge. (shrink)

What makes it true when we say that something is not the case? Truthmaker maximalists think that every truth has a truthmaker—some fact in the world—that makes it true. No such facts can be found for the socalled negative truths. If a proposition is true when it has a truthmaker, then it would be false when it has no truthmaker. I therefore argue that negative truths, such as t<p>, are best understood as falsehoods, f<p>.

According to the Ignorance Factivity Thesis, for every proposition p, one is ignorant of p only if p is a truth. By contrast, according to the Ignorance Non-Factivity Thesis, it is false that, for every proposition p, one is ignorant of p only if p is a truth. I argue that, on balance, the case for the latter thesis is stronger than the case for the former.

Narratives are never meant to be neutral in their rhetorical intent. They have power not onlyto reveal realities and prevail worldviews but also to create new realities and new worldviewsby refuting illusions and falsehood, and affirming the truth. The Judith narrative is a goodexample for the exploration of this claim. This article contributes by employing the thematiclevel of analysis, the veridictory square in particular, of the Greimassian approach to narratives,to map out the possible illusions and affirming the truth within (...) the second temple Judaism.The study of the veridictory square as informed by the level of analysis, mentioned above,seems to persuade the reader by first, extracting the truth from illusion and thereafter exposingand shaming falsehood in Judith. Subsequently, the article asserts that Judith is not neutral in itsintent but was designed to deal with illusive ideas that might have been impacting the wellbeingof the second temple Judaism.

Sophists and rhetoricians like Gorgias are often accused of disregarding truth and rationality: their speeches seem to aim only at effective persuasion, and be constrained by nothing but persuasiveness itself. In his extant texts Gorgias claims that language does not represent external objects or communicate internal states, but merely generates behavioural responses in people. It has been argued that this perspective erodes the possibility of rationally assessing speeches by making persuasiveness the only norm, and persuasive power the only virtue, of (...) speech. Against this view, I show how Gorgias’ texts support a robust normativity of language that goes well beyond persuasion while remaining non-representational. Gorgias’ claims that a speech can be persuasive and false, or true and unpersuasive, reveal pragmatic, epistemic, and agonistic constraints on the validity of speech that are neither representational nor reducible to sheer persuasiveness.

Sextus Empiricus ascribes to Epicurus a curious account of truth and falsehood, according to which these characteristics belong to things in the world about which one speaks, not to what one says about them. I propose an interpretation that takes this account seriously and explains the connection between truth and existence that the Epicureans also seem to recognise. I then examine a second Epicurean account of truth and falsehood and show how it is related to the first.

Current epistemological dogma has it that the twin goalsof believing truths and avoiding errors exhaust our cognitive aspirations.

In particular, this view implies that all the epistemic value of knowledge must be derived from the value of the (...) two goals cited in TG. I argue that this implication is false, and thus that the TG view must be abandoned. I propose a candidate to replace the TG view that makes better sense of the value of knowledge. (shrink)

The logic with independent truth and falsehood operators TFL is proposed. In TFL(→) standard truth-conditions for the implication are adopted. Nevertheless the laws of classical logic are not valid. In this language more then 107 different binary connectives can be defined. So this logic can be treated as universal logic relatively to the class of sentential logics.

Some philosophers argue that false speech and false belief are impossible. In the Sophist, Plato addresses this 'falsehood paradox', which purports to prove that one can neither say nor believe falsehoods. In this book Paolo Crivelli closely examines the whole dialogue and shows how Plato's brilliant solution to the paradox is radically different from those put forward by modern philosophers. He surveys and critically discusses the vast range of literature which has developed around the Sophist over the past fifty (...) years, and provides original solutions to several problems that are so far unsolved. His book will be important for all who are interested in the Sophist and in ancient ontology and philosophy of language more generally. (shrink)

We discuss misinformation about “the liar antinomy” with special reference to Tarski’s 1933 truth-definition paper [1]. Lies are speech-acts, not merely sentences or propositions. Roughly, lies are statements of propositions not believed by their speakers. Speakers who state their false beliefs are often not lying. And speakers who state true propositions that they don’t believe are often lying—regardless of whether the non-belief is disbelief. Persons who state propositions on which they have no opinion are lying as much as those who (...) state propositions they believe to be false. Not all lies are statements of false propositions—some lies are true; some have no truth-value. People who only occasionally lie are not liars: roughly, liars repeatedly and habitually lie. Some half-truths are statements intended to mislead even though the speakers “interpret” the sentences used as expressing true propositions. Others are statements of propositions believed by the speakers to be questionable but without revealing their supposed problematic nature. The two “formulations” of “the antinomy of the liar” in [1], pp.157–8 and 161–2, have nothing to do with lying or liars. The first focuses on an “expression” Tarski calls ‘c’, namely the following. -/- c is not a true sentence -/- The second focuses on another “expression”, also called ‘c’, namely the following. -/- for all p, if c is identical with the sentence ‘p’, then not p -/- Without argumentation or even discussion, Tarski implies that these strange “expressions” are English sentences.

The Courage of the Truth is the last course that Michel Foucault delivered at the College de France before his death in 1984. In this course, he continues the theme of the previous year's lectures in exploring the notion of "truth-telling" in politics to establish a number of ethically irreducible conditionsbased on courage and conviction.

"The Sophist seems to be concerned with two things: being and nonbeing, on the one hand, and true and false speech, on the other. If speech is either true or false speech, it seems not even plausible for being to be either being or nonbeing, since we would then be compelled to say that nonbeing is as much being as false speech is speech. If nonbeing, however, is being, then nonbeing cannot be nonbeing, for otherwise the falseness of false speech (...) would not consist in its saying 'nonbeing.' And, in turn, if nonbeing is nonbeing, the falseness of' false speech again cannot consist in its saying 'nonbeing,' for it would then not be saying anything. If we then say that nonbeing is appearing, and appearing is not unqualified nonbeing, being is being and appearing, and we want to distinguish between the strict identity which belongs to being and the likeness of' nonbeing to the strict identity of being. We say, then, 'Here is Socrates himself' and 'Here is a likeness of Socrates.' Everything in the likeness of Socrates that is a likeness of' Socrates himself will generate a true speech of Socrates identical to another speech true of Socrates himself. Everything, how ever, in the likeness of Socrates that is not a likeness of Socrates himself yields a false speech of Socrates. Among the false speeches of Socrates would be, for example, the paint on Socrates' portrait but not the color of the paint that is true of Socrates himself. The paint, then, without the color (per impossibile), is not true of Socrates, but it certainly is not a likeness of Socrates either. The paint must be together with its color in order for it to be both a likeness of Socrates and nonbeing, but it seems to be utterly mysterious how by being together it can be that and by being apart it ceases to be anything of the sort. If every thing then is just what it is and nothing else, it is impossible for there to be any speech, either true or false, for speech is impossible unless something can be put together with something else..

Wherever there is life, there are lies. Slick-suited politicians lie on the podium, ready to tell voters what they want to hear. Cheating lovers, swindling businessmen, double-crossing villains – all liars. But nature lies too – the cheetah crouching in the tall grass waiting to pounce, its spots and straw-coloured fur blending in with its surroundings, the chameleon with its adaptable skin, the octopus hiding in its cave. Juan Jacinto Muñoz-Rengel uncovers the slippery history of lies, some dark and elusive, (...) others thunderous and dazzling. From primeval forests to modern politics, he explores the uncomfortable truths of our white lies, fudged facts and blatant deceptions. For centuries, philosophers, writers and poets have grappled with the paradox of what’s fact and what’s fiction. So who can we really believe? Our friends? Our partners? Our leaders? Can we even trust ourselves? Truly, this is the only book in which the abundance of lies on its pages is a sign of success. Or maybe it isn’t. Who can really tell? (shrink)

'Post-truth', Oxford Dictionary's 2016 word of the year, appears to cover only the turn away from reason in contemporary politics. In fact the truth behind 'post-truth' is historically and philosophically more complex. As Fuller shows in this book, it reaches into the nature of knowledge itself.

In Far-Right Revisionism and the End of History: Alt/Histories, historians, sociologists, neuroscientists, lawyers, cultural critics, and literary and media scholars come together to offer an interconnected and comparative collection for understanding how contemporary far-right, neo-fascist, Alt-Right, Identitarian, and New Right movements have proposed revisions and counter-narratives to accepted understandings of history, fact and narrative. The innovative essays found here bring forward urgent questions to diverse public, academic, and politically-minded audiences interested in how historical understandings of race, gender, class, nationalism, religion, (...) law, technology and the sciences have been distorted by these far-right movements. If scholars of the last twenty years, like Francis Fukuyama, believed that neoliberalism marked an "end of history," this volume shows how the far right is effectively threatening democracy and its institutions through the dissemination of alt-facts and histories.

Hilary Putnam deals in this book with some of the most fundamental persistent problems in philosophy: the nature of truth, knowledge and rationality. His aim is to break down the fixed categories of thought which have always appeared to define and constrain the permissible solutions to these problems.

Lying in Early Modern English Culture is a major study of ideas of truth and falsehood in early modern England from the advent of the Reformation to the aftermath of the failed Gunpowder Plot. The period is characterised by panic and chaos when few had any idea how religious, cultural, and social life would develop after the traumatic division of Christendom. While many saw the need for a secular power to define the truth others declared that their allegiances belonged (...) elsewhere. Accordingly there was a constant battle between competing authorities for the right to declare what was the truth and so label opponents as liars. Issues of truth and lying were, therefore, a constant feature of everyday life and determined ideas of individual identity, politics, speech, sex, marriage, and social behaviour, as well as philosophy and religion. This book is a cultural history of truth and lying from the 1530s to the 1610s, showing how lying needs to be understood in action as well as in theory. Unlike most histories of lying, it concentrates on a series of particular events reading them in terms of academic theories and more popular notions of lying. The book covers a wide range of material such as the trials of Ann Boleyn and Thomas More, the divorce of Frances Howard, and the murder of Anthony James by Annis and George Dell; works of literature such as Othello, The Faerie Queene, A Mirror for Magistrates, and The Unfortunate Traveller; works of popular culture such as the herring pamphlet of 1597; and major writings by Castiglione, Montaigne, Erasmus, Luther, and Tyndale.

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 (...) higher-order values. This method is based on the concept of a multilattice. If the method is applied to the set of truth values of Belnap's “useful four-valued logic”, one obtains a trilattice, and, more generally, structures here called Belnap-trilattices. As in Priest's case, it is shown that the generalized truth values motivated by hyper-contradictions have no effect on the logic. Whereas Priest's construction in terms of designated truth values always results in his Logic of Paradox, the present construction in terms of truth and falsity orderings always results in First Degree Entailment. However, it is observed that applying the multilattice-approach to Priest's initial set of truth values leads to an interesting algebraic structure of a “bi-and-a-half” lattice which determines seven-valued logics different from Priest's Logic of Paradox.

Throughout history, humans have always indulged in certain irrationalities and held some fairly wrong-headed beliefs. But in his newest book, philosopher Lee McIntyre shows how we've now reached a watershed moment for ignorance in the modern era, due to the volume of misinformation, the speed with which it can be digitally disseminated, and the savvy exploitation of our cognitive weaknesses by those who wish to advance their ideological agendas. In _Respecting Truth: Willful Ignorance in the Internet Age_, McIntyre issues a (...) call to fight back against this slide into the witless abyss. In the tradition of Galileo, the author champions the importance of using tested scientific methods for arriving at true beliefs, and shows how our future survival is dependent on a more widespread, reasonable world.

Judgments of the rationality of beliefs must take the costs of acquiring and possessing beliefs into consideration. In that case, certain false beliefs, especially those that are associated with the benefits of a cohesive community, can be seen to be useful for an agent and perhaps instrumentally rational to hold. A distinction should be made between excusable misbeliefs, which a rational agent should tolerate, and misbeliefs that are defensible in their own right because they confer benefits on the agent. Likely (...) candidates for such misbeliefs are to be found in the realm of nationalism and religion, where the possession costs of true beliefs are high, and where collective beliefs in falsehoods may allow for a cohesive community. We discuss the paradoxes of reflective awareness involved in the idea of deliberately embracing falsehoods. More rigorous, fully reflective concepts of rationality would still disallow false beliefs, but such demanding versions of rationality would commit agents to pay large costs, thereby weakening the motivation for acquiring true beliefs.

Nietzsche often gives the impression that all human beliefs are false. Some scholars, like Maudemarie Clark, believe that such a “falsification thesis” is unacceptable and try to limit Nietzsche's commitment to it, claiming that he abandons it in his very last works. Others, like Lanier Anderson and Nadeem Hussain, take it in ways that make it true and locate it in all. I argue that the view that is common to both approaches—that Nietzsche held that thesis in the first place—is (...) unjustified. To that end, I interpret the texts where these scholars claim to find the thesis in a way that shows that they do not commit Nietzsche to it, and I offer some reasons for thinking that this is a more fruitful way of interpreting his views on the importance of truth—and falsehood—and their function in the economy of human life.

Goldstein attempts to establish a middle position between the idealist and the realist arguments concerning truth and fact in history. Though fact serves as the touchstone of truth, we cannot verify propositions, especially historical propositions, in terms of fact. Nowell-Smith argues that Goldstein cannot acknowledge the importance of reality for everyday affairs, while denying its importance in history. Goldstein could have avoided such problems by realizing that if he is an opponent of historical realism, he must be a supporter of (...) historical idealism. He could resolve Nowell-Smith's objections by adopting the Kantian argument which contrasts two types of judgment; judgment proper and particular attempts at judgment. Statements of objective fact, including historical facts, would be considered judgment proper. This would still allow for some judgments which did not fulfill objective criteria, but could count as knowledge. (shrink)

Chapter Θ10 of Aristotle's Metaphysics is traditionally taken to be about the truth of intuitions, namely episodes of an immediate and sub-propositional grasp of entities. This exegesis however saddles Aristotle with a broken-backed theory of truth because in other passages of his works he claims that truth and falsehood apply only to items of a propositional nature and denies that sub-propositional items can be true or false. An alternative exegesis is preferable which takes Θ10 to be about the truth (...) of existential statements and judgements concerning simple items. (shrink)

Truth, Christopher Norris reminds us, is very much out of fashion at the moment whether at the hands of politicians, media pundits, or purveyors of postmodern wisdom in cultural and literary studies. Across a range of disciplines the idea has taken hold that truth-talk is either redundant or the product of epistemic might. Questions of truth and falsehood are always internal to some specific language-game; history is just another kind of fiction; philosophy is only a kind of writing; law (...) is a wholly rhetorical practice. In _Reclaiming Truth_, Norris critiques these fashionable trends of thought and mounts a specific challenge to cultural relativist doctrines in epistemology, philosophy of science, ethics, and political theory. Norris presents his case in a series of closely argued chapters that take issue with the relativist position. He attempts to rehabilitate the value of truth in philosophy of science by restoring a lost distinction between concept and metaphor and argues that theoretical discourse, so far from being an inconsequential activity, has very real consequences, particularly in ethics and politics. This debate has become skewed, he suggests, through the widespread and typically postmodern idea that truth-claims must always go along with a presumptive or authoritarian bid to silence opposing views. On the contrary, there is nothing as dogmatic—or as silencing—as a relativism that acknowledges no shared truth conditions for valid or responsible discourse. Norris also offers a timely reassessment of several thinkers—Althusser and Derrida among them—whose reception history has been distorted by the vagaries of short-term intellectual fashion. _Reclaiming Truth _will be welcomed by readers concerned with the uses and abuses of theory at a time when such questions are in urgent need of sustained and serious debate.
