Plato's examination of False Statement is, like many of his discussions in the later dialogues, a mixture of complete lucidity with extreme obscurity. Any English student who seeks to understand it will of course turn first to Professor Cornford's translation and commentary; and if he next reads what M. Diès has to say in the Introduction to his Budé edition of the Sophist he will, I think, have sufficient acquaintance with the views of modern Platonic scholars on the (...) subject. For myself, at least, I have not gained any further understanding from other writers than these two. (shrink)

A pair of studies demonstrates that simply asking children to make a blatantly false accusation in the guise of helping others can result in both immediate and long-term false claims. In the pilot study, the initial willingness to make a blatantly false statement was associated with some children making false statements a week later despite being told that the first interviewer had made mistakes during the initial interview. On a positive note, the majority of participants (...) accurately stated that they did not have first-hand knowledge of their accusation's accuracy. Across both studies, the rate of false accusation rates was high. The main experiment demonstrated that children who were young, possessed the lowest verbal intelligence or who were from the lowest SES homes made the most accusations. These findings illustrate not only the dangers of encouraging children to make false statements, but the ease and durability of making such false statements. (shrink)

Financial accountants falsify financial statements by means of financial techniques such as financial practices and financial standards, and when compared with conventional financial data, it is found that the falsified financial data often lack correlation or even contradict each other in terms of financial data indicators. At the same time, there are also inherent differences in reporting patterns from conventional financial data, but these differences are difficult to test manually. In this paper, the fuzzy C-means clustering method is used to (...) amplify these differences and thus identify false financial statements. In the proposed algorithm, firstly, the normalization constraint of the FCM clustering algorithm on the sum of affiliation of individual samples is relaxed to the constraint on the sum of affiliation of all samples, thus reducing the sensitivity of the algorithm to noise and isolated points; secondly, a new affiliation correction method is proposed to address the problem that the difference in affiliation is too large after the relaxation of the constraint. In the discussion of this paper, most of the information comes from the annual reports of companies, administrative penalty decisions of the Securities Regulatory Commission, and some information comes from research reports made by securities institutions, which are limited sources of information. The proposed method can correct the affiliation to a reasonable range, effectively avoiding the problem that some samples have too much affiliation and become a class of their own and also avoiding the problem that it is difficult to choose the termination threshold of the algorithm iteration due to too little affiliation, and can ensure that the constraint on the sum of affiliation of all samples is always satisfied during the iteration of the algorithm. The method has the characteristics of high recognition accuracy and has the significance of theoretical method innovation. (shrink)

False dilemma is a specific form of reasoning : despite the fact that it is based on a deductively valid argument form, it is rightly depicted as fallacy. A systematic exposition of false dilemma is missing in theoretical approaches to fallacies. This article formulates six criteria for a well-grounded exposition of a fallacy, suggesting also a systematic exposition of false dilemma. These criteria can be used to both explain, and categorise, the various false dilemma fallacies. The (...) article introduces distinction between four types of false dilemma : False quandary, Defeasible sound quandary, False obstruction and Defeasible sound obstruction. The types of criticism appropriate for each variant of false dilemma are suggested. Being able to discover false dilemma in situations when it is important to make good and free choices is a significant dimension of critical thinking. It may liberate us from accepting the consequences that necessarily follow from prearranged alternatives, when these are not the only alternatives possible. It may also liberate us from refraining from actions on the basis of obstructive disjunctive statements. In that respect, the faculty of critical thinking directed at uncovering reasoning based on false dilemma may also initiate the discovery of new alternatives, or discover the ways of unifying seemingly opposing alternatives. Thus, a well-developed ability to understand the tricky argumentative moves of false dilemma may be a good step towards initiating some features of creative thinking. (shrink)

Of the later dialogues of Plato, the Sophists stand out. This article highlights the concept of sophist as propounded by Plato. A didactic approach runs through the text. Socrates harps on the relation between sophist, philosopher and a statesman. Are they three different or they are the same. The basic idea that Plato wants to convey is, both features highlight some of the key enigmas of the dialogue: What is the relation between the outer and middle parts? How seriously are (...) we to take the outer part? And is there a genuine, and successful, attempt to say what the sophist is? The article focuses on two key problems discussed and solved in the middle part: the late-learners' problem, and the problem of false statement. The article also discusses communion of kinds and Plato's idea of the four quartets. (shrink)

Lies are typically defined as believed falsehoods asserted with the intention of deceiving the hearer. A particularly problematic case for this definition is that of false implicatures. These are prototypically cases where the proposition expressed by the speaker's utterance is true, yet an implicature conveyed by this proposition in context is false. However, implicature is a diverse category and whether a blanket statement such as “false implicatures are lies,” as some have argued can account for all (...) of them is open to investigation. We present an experimental investigation of whether naïve participants define different types of implicatures as lies. Our results show that only a couple of types of implicatures were strongly rated as lies by participants. These results suggest that participants distinguish between different types of communicated meanings on linguistic grounds, contributing both to the literature on lying, as well as to theoretical discussions of how different types of meaning are communicated.

Minimalism about truth-aptitude, if correct, would undercut expressivism about moral discourse. Indeed, it would undercut nonfactualism about any area of discourse. But it cannot be correct, for there are areas, about which people hold beliefs and make statements, to which nonfactualism uncontroversially applies. Or so I will argue. I will be thereby challenging John Divers and Alexander Miller’s [3] appeal to minimalism about truth-aptitude in defending a certain argument against expressivism about value. But I will not be defending expressivism. For (...) what is wrong with minimalism about truth-aptitude is, in my view, also what is wrong with expressivism: both mistakenly assume that for an utterance to qualify as a statement or a psychological state as a belief, it must be capable of being true or false.

The paradox that there can be no such thing as falsity is treated by Plato in a number of places. As exploited in the early dialogue Euthydemus it appears to rest on a simple equivocation. A false statement would be one that stated what is not, but to state what is not is to state nothing; so a false statement would in fact be a non-statement, no statement at all.

Over a period of more than twenty years, Sybil Wolfram gave lectures at Oxford University on Philosophical Logic, a major component of most of the undergraduate degree programmes. She herself had been introduced to the subject by Peter Strawson, and saw herself as working very much within the Strawsonian tradition. Central to this tradition, which began with Strawson's seminal attack on Russell's theory of descriptions in ‘On Referring' (1950), is the distinction between a sentence and what is said by a (...) sentence − Strawson initially called the latter a use of a sentence, and sometimes a proposition , but his most frequent term for what is said , which Wolfram consistently adopts, is the statement expressed.1 The force of the distinction is clearly illustrated in ‘On Referring', which uses it to undermine the common assumption that any sentence must be either true, or false, or meaningless. Russell had argued on this basis that a sentence such as ‘The King of France is bald' (which is clearly neither true nor meaningless) must be false, but Strawson points out that if we distinguish between the sentence itself and the statement that it expresses (on some occasion of use), we can quite easily combine the admission that the sentence is meaningful − for it can in appropriate circumstances be used to express true and false statements − with the claim that nevertheless if the circumstances are ‘inappropriate' (in particular, when there is no current King of France), the sentence can fail to express a statement that is either true or false. On this picture, therefore, it is sentences that are meaningful, but statements that are the primary bearers of truth. (shrink)

Can there be a non-reductivist, source-based explanation of the use of normative language in statements describing the law and legal situations? This problem was formulated by Joseph Raz, who also claimed to have solved it. According to his well-known doctrine of ‘detached’ statements, normative legal statements can be informatively made by speakers who merely adopt, without necessarily sharing, the point of view of someone who accepts that legal norms are justified and ought to be followed. In this paper I defend (...) two theses. I argue, first, that the notion of a detached statement cannot be made to work, and that Raz’s problem is thus not thereby solved. But the problem itself, I also suggest, is a false one. (shrink)

The version of the paradox of false judgement examined at Tht. 188c10–189b9 relies on the assumption that to judge falsehoods is to judge the things which are not. The presentation of the argument displays several syntactic ambiguities: at several points it allows the reader to adopt different syntactic connections between the components of sentences. For instance, when Socrates says that in a false judgement the cognizer is “he who judges the things which are not about anything whatsoever” (188d3–4), (...) how should the clause “about anything whatsoever” be construed? In common with “he who judges” and “the things which are not” (in which case the cognizer would be “he who judges about anything whatsoever the things which are not about it”), or exclusively with “he who judges” (in which case the cognizer would be “he who judges about anything whatsoever the things which are not”)? The most plausible answer is that both construals are envisaged. Accordingly, the argument has two branches corresponding to these two alternative construals. In particular, it attempts to show that in both cases the cognizer will address what does not exist – an impossibility. The idea that a false judgement is concerned with what is not about its reference has a clear echo in the Sophist. The way in which the problem is handled in the Theaetetus provides a hint that can help to find a solution for the hotly debated issue of the interpretation of the Sophist’s account of false statement.

Discrepancies between the Uniform Determination of Death Act (UDDA) and the adult and pediatric diagnostic guidelines for brain death (BD) (the “Guidelines”) have motivated proposals to revise the UDDA. A revision proposed by Lewis, Bonnie and Pope (the RUDDA), has received particular attention, the three novelties of which would be: (1) to specify the Guidelines as the legally recognized “medical standard,” (2) to exclude hypothalamic function from the category of “brain function,” and (3) to authorize physicians to conduct an apnea (...) test without consent and even over a proxy’s objection. One hundred seven experts in medicine, bioethics, philosophy, and law, spanning a wide variety of perspectives, have come together in agreement that while the UDDA needs revision, the RUDDA is not the way to do it. Specifically, (1) the Guidelines have a non-negligible risk of false-positive error, (2) hypothalamic function is more relevant to the organism as a whole than any brainstem reflex, and (3) the apnea test carries a risk of precipitating BD in a non-BD patient, provides no benefit to the patient, does not reliably accomplish its intended purpose, and is not even absolutely necessary for diagnosing BD according to the internal logic of the Guidelines; it should at the very least require informed consent, as do many procedures that are much more beneficial and less risky. Finally, objections to a neurologic criterion of death are not based only on religious belief or ignorance. People have a right to not have a concept of death that experts vigorously debate imposed upon them against their judgment and conscience; any revision of the UDDA should therefore contain an opt-out clause for those who accept only a circulatory-respiratory criterion.

In De interpretatione 9, Aristotle argues against the fatalist view that if statements about future contingent singular events (e.g. ‘There will be a sea battle tomorrow,’ ‘There will not be a sea battle tomorrow’) are already true or false, then the events to which those statements refer will necessarily occur or necessarily not occur. Scholars have generally held that, to refute this argument, Aristotle allows that future contingent statements are exempt from either the principle of bivalence, or the law (...) of excluded middle. This paper offers a new interpretation of Aristotle’s refutation of fatalism. According to this interpretation, each member of a pair of contradictory future contingent statements, in virtue of expressing modal necessity, is simply false. (shrink)

1. Object of this note . In his lively essay, “Between Analytic and Empirical,” , Mr. J. W. N. Watkins challenges the empiricist identification of synthetic statements with empirical ones by arguing that there exists an important class of statements which are synthetic, i.e. not analytically true or false, and yet not empirical. I find Mr. Watkins's arguments very stimulating, but I do not think they provide a sound basis for his contention. In the present note, I wish to (...) indicate what seem to me the principal flaws in Mr. Watkins's reasoning, and to make some additional comments on the issues raised by his discussion. (shrink)

This paper offers an interpretation of Plato's Cratylus 427d1-431c3 that supports a reading of the dialogue as a whole as concluding in favour of a conventionalist account of naming. While many previous interpretations note the value of this passage as evidence for Platonic investigations of false propositions, this paper argues that its demonstration that there can be false (or incorrect) naming in turn refutes the naturalist account of naming; that is, it shows that a natural relation between name (...) and nominatum is neither a necessary nor a sufficient condition for reference. Socrates secures this outcome by using demonstratives and their concomitants to show how any putative natural imitative link between name and object may be overridden. Furthermore, Socrates' employment of demonstratives and context-dependent statements in his case-studies of false naming speaks in favour of a reading of this passage as primarily focussing on naming rather than on propositions in general.

According to the standard view, alethic (or modal) statements are intensional in that the Principle of Substitution (PS) fails for them -- e.g. substituting 'nine' in "Necessarily, nine is composite" with the co-referring 'the number of planets' turns this statement from true to false. It is argued in the paper that we could avoid ascribing intensionality to alethic statements altogether by separating between singular and functional uses of definite descriptions: on the singular use the description given above amounts (...) to 'the actual number of planets', which is salva veritate substitutable to 'nine' in all alethic statements; on the functional use, in turn, that description is really a function from possible worlds to numbers, and thus the Principle of Substitution is not violated in this case either, since such a function cannot be held to be co-referential with 'nine'.

Let us now consider the third class of statements, those completely nonrestrictive. For example, "Something exists." Since this is the pure contradictory of the wholly restrictive, "Nothing exists," which we have found reason to regard as impossible, and since the contradictory of an impossible statement is necessary, we should expect "Something exists" to be necessarily true, a statement valid a priori. And we see that it excludes nothing from existence, except bare "nothing" itself. But the existence of bare (...) nothing is no existence. Further, "Something exists" is in no conceivable circumstances falsifiable, since the falsifying experience would have to exist, and it would also have to be the experience of something existing--at least if, as I should maintain, experience is essentially a relative term, requiring that to which it is relative, or of which it is the experience. But though "Something exists" is unfalsifiable, it is verified every moment. Could the verifiable but in any conceivable world absolutely unfalsifiable be false? I hold that the necessarily true must be knowable as true and only as true, and that, conversely, whatever is in principle verifiable though not falsifiable is thereby shown to be necessarily true.

The present study examines cross-cultural differences in people’s concept of lying with regard to the question of whether lying requires an agent to _say_ something they believe to be false. While prominent philosophical views maintain that lying entails that a person explicitly expresses a believed-false claim, recent research suggests that people’s concept of lying might also include certain kinds of deception that are communicated more indirectly. An important drawback of previous empirical work on this topic is that only (...) few studies have investigated people’s concept of lying in non-Western samples. In the present study, we compare people’s intuitions about lying with indirect deceptions (i.e., presuppositions, conversational implicatures, and non-verbal actions) in a sample of _N_ = 255 participants from Russia and _N_ = 300 participants from the United Kingdom. Our findings show a strong degree of similarity between lie ratings of participants from Russia and the United Kingdom, with both samples holding it possible for agents to lie with deceptive statements and actions that do not involve the agent _saying_ something they believe to be false.

First, I show that the semantic thesis of scientific realism may be relaxed significantly—to allow that some scientific discourse is not truth-valued—without making any concessions concerning the epistemic or methodological theses that lie at realism’s core. Second, I illustrate how relaxing the semantic thesis allows realists to avoid positing abstract entities and to fend off objections to the “no miracles” argument from positions such as cognitive instrumentalism. Third, I argue that the semantic thesis of scientific realism should be relaxed because (...) it is possible for scientific statements to be partially true, and hence approximately true, without being false.

In his Quadratura, Paul of Venice considers a sophism involving time and tense which appears to show that there is a valid inference which is also invalid. Consider this inference concerning some proposition A : A will signify only that everything true will be false, so A will be false. Call this inference B. A and B are the basis of an insoluble-that is, a Liar-like paradox. Like the sequence of statements in Yablo's paradox, B looks ahead to (...) a moment when A will be false, yet that moment may never come. In the Quadratura, Paul follows the solution to insolubles found in the collection of elementary treatises known as the Logica Oxoniensis, which posits an implicit assertion of its own truth in insolubles like B. However, in the treatise on insolubles in his Logica Magna, Paul develops and endorses a different solution that takes insolubles at face value. We consider how both types of solution apply to A and B : on both, B is valid. But on one, B has true premises and false conclusion, and contradictories can be false together; on the other (following the Logica Oxoniensis), the counterexample is rejected. (shrink)

In 385B-C of the Cratylus, Plato appears to be formulating a version of the correspondence theory of truth, in such a way that it applies not only to discourse, but to individual names as well. However commentators who have remarked on this passage, either take exception to the reasoning, or find it necessary to interpret the conclusion with qualifications that Plato never could have intended. Richard Robinson, for example, on p.328 of “A Criticism of Plato’s Cratylus”, sums up the argument (...) thus:... since statements have a truthvalue, their parts, including names, must have a truthvalue too. Therefore names are true or false.and criticises it for involving a fallacy of division. Lorenz and Mittelstrasse, by contrast, construe the argument as validly proceeding from the true-false distinction of sentences to a corresponding true-false distinction of their parts. (shrink)

In a survey on research misconduct, roughly 20% of the respondents admitted that they have submitted federal grant proposals that include scholars as research participants even though those scholars were not expected to contribute to the research effort.

Moreover, it is not only the offending academics and the (...) false investigators that face civil and criminal penalties because administrators may also be liable if they sign off on proposals and are in a position to know that false investigators might be included. Policy recommendations that should reduce the use of false investigators include changing institutional cultures, better training and oversight of the responsible conduct of research, and, most importantly, making all grant reviews double blind.

This text aims to provide a contribution to the analysis of beliefs and, through the elaboration of the notion of good reasons, to make a significant contribution to the theory of rationality. It examines the main theories that have been used in the social sciences and psychology for the explanation of beliefs. The author develops a particular model which enables him to show that people often have good reasons to believe in false ideas. The central idea of this model (...) is that people often draw controversial conclusions from valid arguments because they introduce implicit statements which they do not perceive, since they treat them - with good reasons - as self-evident. Hence they can hold doubtful, or even false, conclusions and regard them as solidly grounded. Boudon shows that this model can be used to reinterpret many findings from the sociology of religion and the sociology of knowledge, as well as from cognitive psychology. (shrink)

Our acceptance of falsely dichotomous statements is often intellectually distorting. It restricts imagination, limits opportunities, and lends support to pseudo-logical arguments. In conflict situations, the presumption that there are only two sides is often a harmful distortion. Why do so many false dichotomies seem plausible? Are all dichotomies false? What are the alternatives, if any, to such fundamental dichotomies as ‘true/false’, ‘yes/no’, ‘proponent/opponent,’ and ‘accept/reject’?

William of Ockham discussed the fallacy of amphiboly twice in his writings. The first treatment was in his Expositio super libros Elenchorum, where he simply presents Aristotle’s treatment, updates it with some Latin examples, and tells us it is not too important, since we do not often run into cases of ambiguity of thiskind. Later, in his Summa logicae, however, he extends his treatment appreciably. He here includes under ambiguous statements philosophical and theological sentences which are improperly stated. Led by (...) Aristotle, Augustine and Anselm, Ockham finds that in their writings they give us instances of improper statements which need to be restated properly before they can be evaluated as true or false. These leads provide for Ockham a key to unlocking the teaching treasures of the Ancients. (shrink)

The traditional analysis of the basic version of the double-slit experiment leads to the conclusion that wave-particle duality is a fundamental fact of nature. However, such a conclusion means to imply that we are not only required to have two contradictory pictures of reality but also compelled to abandon the objectiveness of the truth values, “true” and “false”. Yet, even if we could accept wave-like behavior of quantum particles as the best explanation for the build-up of an interference pattern (...) in the double-slit experiment, without the objectivity of the truth values we would never have certainty regarding any statement about the world. The present paper discusses ways to reconcile the correct description of the double-slit experiment with the objectiveness of “true” and “false”. (shrink)

“The Standard Interpretation” of Descartes on material falsity states that Descartes believed that materially false ideas (MFIs) lack “objective reality” [realitas objectiva]. The argument for the Standard Interpretation depends on a statement from the “Third Meditation” that MFIs are caused by nothing. This statement, in conjunction with a causal principle introduced by Descartes, seems to entail that MFIs lack objective reality. However, the Standard Interpretation is incorrect. First, I argue that, despite initial appearances, the manner in which (...) Descartes understands the proposition that MFIs are caused by nothing does not entail that they lack objective reality. Secondly, I argue that Descartes is committed to the objective reality of MFIs because of his quasi-scholastic explanation of MFIs. (shrink)

Disjunctive Syllogism, that is, the inference from 'not-A or B' and 'A', to 'B' can lead from true premises to a false conclusion if each of the sentences 'A' and 'not-A' is a statement of a partial truth such that affirming one of them amounts to denying the other, without each being the contradictory of the other.

Mindfulness/mindlessness as a new factor influencing false memories: evidence from imagination inflation and modified premature cognitive commitment study Two effects that can influence the creation of false memories were investigated. First, the classic effect of imagination inflation was investigated.

Then half of (...) the subjects imagined performing some other actions. One week later half of the subjects were exposed to false information that they have the tendency to underestimate the quantity of many occurrences in everyday life. The surprising finding was that imagination inflation effect had not emerged. Nevertheless, the exposure to information about fictitious deficit led to bias correction and to source monitoring errors in which actions that had not been presented were recollected as having been imagined or heard.

One of Marx‘s and Engels‘ main claims (hereafter ―original Marxism) in their account of the historical ―inevitability of the collapse of capitalism is that one‘s material (economic) conditions, not one‘s ideas, arguments or philosophy, determines one‘s ―consciousness and actions. However, the self-reference in this characterization of philosophical views generates a paradox analogous to the 7th century B.C. Epimenides ―Liar paradox. The Epimenides-paradox arises when Epimenides, a Cretan, states that all Cretans are liars. Epimenides-statement is paradoxical in the sense that (...) if it is true then it is false. Similarly, the Marxist claim that all philosophers who purport to state the cause of all social changes must be wrong, where Marx and Engels are themselves philosophers stating just such a claim, generates a paradox analogous to the ― Epimenides Liar paradox. This leads to what Engels himself calls a―false consciousness, i.e., a failure to understand the true causes of social change. This paradox can only be escaped by abandoning at least one of original Marxism‘s core doctrines. (shrink)

Rather than considering paradox in a literal sense to be unresolvable, both Bhartṛhari and the Daoists develop a distinctive hermeneutics to decipher them, always exploring an overarching meaning where the fundamental differences are contained within. The conversation on paradox escapes the boundary of paradox then, as it relates to interpreting negation, and above all, the philosophy of semantics. Being and non-being, one and many, or something being both true and false at the same time are examples found from their (...) texts. Just as the static and dynamic domains of the Dao remain a key to address paradox in Chinese literature, the stratification of speech, wherein deeper layers of speech are capable of resolving the apparent tension found at the surface level, seems central to Bhartṛhari’s approach.
