Reprinted in Oxford Readings in Philosophical Theology, Volume 1: Trinity, Incarnation, and Atonement, Oxford 2009, ed. Michael Rea. A popular argument for the divinity of Jesus goes like this. Jesus claimed to be divine, but if his claim was false, then either he was insane (mad) or lying (bad), both of which are very unlikely; so, he was divine. I present two objections to this argument. The first, the dwindling probabilities objection, contends that even if we make generous probability assignments (...) to the relevant pieces of evidence for Jesus’ divinity, the probability calculus tell us to suspend judgement on the matter. The second, and more telling objection in my opinion, the merely mistaken objection, contends that it is no less plausible to suppose that Jesus was neither mad nor bad but merely mistaken than that he was divine.

Errol Lord explores the boundaries of epistemic normativity. He argues that we can understand these better by thinking about which mental states are competitors in rationality’s competition. He argues that belief, disbelief, and two kinds of suspension of judgment are competitors. Lord shows that there are non-evidential reasons for suspension of judgment. One upshot is an independent motivation for a certain sort of pragmatist view of epistemic rationality.

My dissertation is a systematic defense of the claim that what it is to be rational is to correctly respond to the reasons you possess. The dissertation is split into two parts, each consisting of three chapters. In Part I--Coherence, Possession, and Correctly Responding--I argue that my view has important advantages over popular views in metaethics that tie rationality to coherence (ch. 2), defend a novel view of what it is to possess a reason (ch. 3), and defend a novel (...) view about what it is to act and hold attitudes for normative reasons (ch. 4). In Part II--Foundationalism, Deception, and The Importance of Being Rational--I argue that foundationalists about epistemic rationality should think that the foundational beliefs are held for sufficient reasons (ch. 5), argue that my view solves the New Evil Demon problem for externalism (and solves a related and underapprieciated problem) (ch. 6), and argue that my view can vindicate the thought that we ought to be rational (ch. 7).

We argue that we can avoid epistemic dilemmas by properly understanding the nature and epistemology of the suspension of judgment, with a particular focus on conflicts between higher-order evidence and first-order evidence.

It is often assumed that believing that p for a normative reason consists in nothing more than (i) believing that p for a reason and (ii) that reason’s corresponding to a normative reason to believe that p, where (i) and (ii) are independent factors. This is the Composite View. In this paper, we argue against the Composite View on extensional and theoretical grounds. We advocate an alternative that we call the Prime View. On this view, believing for a normative reason (...) is a distinctive achievement that isn’t exhausted by the mere conjunction of (i) and (ii). Its being an achievement entails that (i) and (ii) are not independent when one believes for a normative reason: minimally, (i) must hold because (ii) holds. Apart from its intrinsic interest, our discussion has important upshots for central issues in epistemology, including the analysis of doxastic justification, the epistemology of perception, and the place of competence in epistemology.

Reasons fundamentalists maintain that we can analyze all derivative normative properties in terms of normative reasons. These theorists famously encounter the Wrong Kind of Reasons problem, since not all reasons for reactions seem relevant for reasons-based analyses. Some have argued that this problem is a general one for many theorists, and claim that this lightens the burden for reasons fundamentalists. We argue in this paper that the reverse is true: the generality of the problem makes life harder for reasons fundamentalists. (...) We do this in two stages. First, we show that reflection on the generality of the distinction between wrong-kind reasons and right-kind reasons shows that not all right-kind reasons are normative reasons. So, not only do reasons-based analyses require a distinction between right-kind reasons and wrong-kind reasons, they also need a distinction between normative right-kind reasons from nonnormative right-kind reasons. We call this the Right Kind of Reasons Problem. In the second stage of the paper, we argue that reasons fundamentalism places tight constraints on its proper solution: in particular, it forbids one from appealing to anything normative to distinguish normative RKRs from nonnormative RKRs. It hence seems that reasons fundamentalists can only appeal to natural facts to solve the problem, but it is unclear which ones can do the job. So, reflection on the generality of the distinction only multiplies the fundamentalist’s problems. We end by exploring several solutions to these problems, and recommend a form of constitutivism as the best. (shrink)

The Ontology for Biomedical Investigations (OBI) is an ontology that provides terms with precisely defined meanings to describe all aspects of how investigations in the biological and medical domains are conducted. OBI re-uses ontologies that provide a representation of biomedical knowledge from the Open Biological and Biomedical Ontologies (OBO) project and adds the ability to describe how this knowledge was derived. We here describe the state of OBI and several applications that are using it, such as adding semantic expressivity to (...) existing databases, building data entry forms, and enabling interoperability between knowledge resources. OBI covers all phases of the investigation process, such as planning, execution and reporting. It represents information and material entities that participate in these processes, as well as roles and functions. Prior to OBI, it was not possible to use a single internally consistent resource that could be applied to multiple types of experiments for these applications. OBI has made this possible by creating terms for entities involved in biological and medical investigations and by importing parts of other biomedical ontologies such as GO, Chemical Entities of Biological Interest (ChEBI) and Phenotype Attribute and Trait Ontology (PATO) without altering their meaning. OBI is being used in a wide range of projects covering genomics, multi-omics, immunology, and catalogs of services. OBI has also spawned other ontologies (Information Artifact Ontology) and methods for importing parts of ontologies (Minimum information to reference an external ontology term (MIREOT)). The OBI project is an open cross-disciplinary collaborative effort, encompassing multiple research communities from around the globe. To date, OBI has created 2366 classes and 40 relations along with textual and formal definitions. The OBI Consortium maintains a web resource providing details on the people, policies, and issues being addressed in association with OBI. (shrink)

Throughout the biological and biomedical sciences there is a growing need for, prescriptive ‘minimum information’ (MI) checklists specifying the key information to include when reporting experimental results are beginning to find favor with experimentalists, analysts, publishers and funders alike. Such checklists aim to ensure that methods, data, analyses and results are described to a level sufficient to support the unambiguous interpretation, sophisticated search, reanalysis and experimental corroboration and reuse of data sets, facilitating the extraction of maximum value from data sets (...) them. However, such ‘minimum information’ MI checklists are usually developed independently by groups working within representatives of particular biologically- or technologically-delineated domains. Consequently, an overview of the full range of checklists can be difficult to establish without intensive searching, and even tracking thetheir individual evolution of single checklists may be a non-trivial exercise. Checklists are also inevitably partially redundant when measured one against another, and where they overlap is far from straightforward. Furthermore, conflicts in scope and arbitrary decisions on wording and sub-structuring make integration difficult. This presents inhibit their use in combination. Overall, these issues present significant difficulties for the users of checklists, especially those in areas such as systems biology, who routinely combine information from multiple biological domains and technology platforms. To address all of the above, we present MIBBI (Minimum Information for Biological and Biomedical Investigations); a web-based communal resource for such checklists, designed to act as a ‘one-stop shop’ for those exploring the range of extant checklist projects, and to foster collaborative, integrative development and ultimately promote gradual integration of checklists.

Audre Lorde’s account of the erotic is one of her most widely celebrated contributions to political theory and feminist activism, but her explanation of the term in her brief essay “Uses of the Erotic” is famously oblique and ambiguous. This article develops a detailed, textually grounded interpretation of Lorde’s erotic, based on an analysis of how Lorde’s essay brings together commitments expressed across her work. I describe four integral elements of Lorde’s erotic: feeling, knowledge, power, and concerted action. The erotic (...) is a way of feeling in the work a person does, which makes possible new knowledge about the self and the social environment— particularly to counteract epistemic oppression imposed by an unjust society. The erotic is a source of power by providing vision and energy for actions integrating a person’s multiple commitments and political interests. It facilitates concerted action and coalition by enhancing a person’s appreciation of their interests and values, while fostering embodied, personal connections that build trust on the basis of shared vulnerability. Thus, the erotic helps build coalitions where genuine differences of perspective and experience can be examined, in resistance against an oppressive society’s epistemic distortions. (shrink)

This paper explores the liar paradox and its implications for logic and philosophical reasoning. It analyzes the paradox using classical logic principles and paraphrases it as "affirmation of the falsity of the very affirmation." The study draws connections between the liar paradox and Hegel's speculative sentence and suggests it functions as a "quasi-speculative sentence." Additionally, it examines parallels with the logocentric predicament and the determinist's assertion, highlighting their paradoxical nature. Through these analyses, the paper aims to illuminate the fundamental paradoxes (...) in our reasoning and logic. (shrink)

A semantic solution to the liar paradox (“This statement is not true”) is presented in this article. Since the liar paradox seems to evince a contradiction, the principle of non-contradiction is preliminarily discussed, in order to determine whether dismissing this principle may be reason enough to stop considering the liar paradox a problem. No conclusive outcome with respect to the value of this principle is aspired to here, so that the inquiry is not concluded at this point and the option (...) to explore an alternative, semantic, solution remains open. This proposed solution is focused on what the liar paradox expresses and what it fails to express. (shrink)

This paper describes the ways in which trolls and bots impede the acquisition of knowledge online. I distinguish between three ways in which trolls and bots can impede knowledge acquisition, namely, by deceiving, by encouraging misplaced skepticism, and by interfering with the acquisition of warrant concerning persons and content encountered online. I argue that these threats are difficult to resist simultaneously. I argue, further, that the threat that trolls and bots pose to knowledge acquisition goes beyond the mere threat of (...) online misinformation, or the more familiar threat posed by liars offline. Trolls and bots are, in effect, fake persons. Consequently, trolls and bots can systemically interfere with knowledge acquisition by manipulating the signals whereby individuals acquire knowledge from one another online. I conclude with a brief discussion of some possible remedies for the problem of fake persons. (shrink)

The purpose of this note is to present a strong form of the liar paradox. It is strong because the logical resources needed to generate the paradox are weak, in each of two senses. First, few expressive resources required: conjunction, negation, and identity. In particular, this form of the liar does not need to make any use of the conditional. Second, few inferential resources are required. These are: (i) conjunction introduction; (ii) substitution of identicals; and (iii) the inference: From ¬(p (...) ∧ p), infer ¬ p. It is, interestingly enough, also essential to the argument that the ‘strong’ form of the diagonal lemma be used: the one that delivers a term λ such that we can prove: λ = ¬ T(⌈λ⌉); rather than just a sentence Λ for which we can prove: Λ ≡ ¬T(⌈Λ⌉). The truth-theoretic principles used to generate the paradox are these: ¬(S ∧ T(⌈¬S⌉); and ¬(¬S ∧ ¬T(⌈¬S⌉). These are classically equivalent to the two directions of the T-scheme, but they are intuitively weaker. The lesson I would like to draw is: There can be no consistent solution to the Liar paradox that does not involve abandoning truth-theoretic principles that should be every bit as dear to our hearts as the T-scheme. So we shall have to learn to live with the Liar, one way or another. (shrink)

This article shows that there is a liar-like paradox that arises for rational credence that relies only on very weak logical and credal principles. The paradox depends on a weak rational reflection principle, logical principles governing conjunction, and principles governing the relationship between rational credence and proof. To respond to this paradox, we must either reject even very weak rational reflection principles or reject some highly plausible logical or credal principle.

In their (2008) article Liar-Like Paradox and Object Language Features C.S. Jenkins and Daniel Nolan (henceforth, JN) argue that it is possible to construct Liar-like paradox in a metalanguage even though its object language is not semantically closed. I do not take issue with this claim. I find fault though with the following points contained in JN’s article: First, that it is possible to construct Liar-like paradox in a metalanguage, even though this metalanguage is not semantically closed. Second, that the (...) presented examples of Liar-like paradox are supposed to be counterexamples to Tarski’s diagnosis of the classic Liar paradox. Third, that JN fail to notice Tarski’s postulate. And finally, that JN fail to recognize that the world they are pondering is not among the possible worlds. (shrink)

Al-Taftāzānī introduces the Liar Paradox, in a commentary on al-Rāzī, in a short passage that is part of a polemic against the ethical rationalism of the Muʿtazila. In this essay, we consider his remarks and their place in the history of the Liar Paradox in Arabic Logic. In the passage, al-Taftāzānī introduces Liar Cycles into the tradition, gives the paradox a puzzling name—the fallacy of the “irrational root” —which became standard, and suggests a connection between the paradox and what it (...) tells us about truth and falsehood, and arguments for divine voluntarism and what they tell us about the nature of goodness and badness. On this last point, we also discuss a passage from al-Rāzī, which suggests similar connections. (shrink)

This article examines the various Liar paradoxes and their near kin, Grelling’s paradox and Gödel’s Incompleteness Theorem with its self-referential Gödel sentence. It finds the family of paradoxes to be generated by circular definition–whether of statements, predicates, or sentences–a manoeuvre that generates pseudo-statements afflicted with the Liar syndrome: semantic vacuity, semantic incoherence, and predicative catalepsy. Such statements, e.g., the self-referential Liar statement, are meaningless, and hence fail to say anything, a point that invalidates the reasoning on which the various paradoxes (...) rest. The seeming plausibility of the paradoxes is due to the fact that often the sentence used to make the pseudo-statement is ambiguous in that it may also be used to make a genuine statement about the pseudo-statement. Hence, if a formal system is to avoid ambiguity and consequent paradox and contradiction, it must distinguish between the two statements the sentence may be used to make. Gödel’s Theorem presents a further complication in that the self-reference involved is sentential rather than statemental. Nevertheless, on the intended interpretation of the system as a formalization of arithmetic, the self-referential Gödel sentence can only be an ambiguous statement, one that is both a pseudo-statement and its genuine double. Consequently, the conclusions commonly drawn from Gödel’s theorem must be deemed unwarranted. Arithmetic might well be formalized in a proper system that either excludes circular definition or introduces disambiguators. (shrink)

The liar paradox is still an open philosophical problem. Most contemporary answers to the paradox target the logical principles underlying the reasoning from the liar sentence to the paradoxical conclusion that the liar sentence is both true and false. In contrast to these answers, Buddhist epistemology offers resources to devise a distinctively epistemological approach to the liar paradox. In this paper, I mobilise these resources and argue that the liar sentence is what Buddhist epistemologists call a contradiction with one’s own (...) words. I situate my argument in the works of Dignāga and Dharmakīrti and show how Buddhist epistemology answers the paradox. (shrink)

In "Convention and Dickie's Institutional Theory" (British Journal of Aesthetics 1980), Catherine Lord maintains the following thesis: (L) If a work of art is defined as institutional and conventional, then the definition precludes the freedom and creativity associated with art. Lord also maintains that the antecedent of this conditional is false. In this note, I argue that (i) certain confusions and assumptions prevent Lord from showing the antecedent is false, and (ii) even if the antecedent is assumed to be true, (...) there are counterexamples to the entire conditional. With regard to (ii), I will suggest that conventionality is necessary for creativity. [This was my first published paper, written as a graduate student, taken from my University of Illinois at Chicago dissertation written with Professor George Dickie on the topic of conventions, utilitizing David Lewis' definition of "convention."].

This paper considers the phenomenon of lying and the implications it has for those subjects who are capable of lying. It is argued that lying is not just intentional untruthfulness, but is intentional untruthfulness plus an insincere invocation of trust. Understood in this way, lying demands of liars a sophistication in relation to themselves, to language, and to those to whom they lie which exceeds the demands on mere truth-tellers.

This is the review of a book by Paula Byrne on Lord Mansfield's great-niece, Dido, whom he raised as his own daughter. Lord Mansfield was the Lord Chief Justice of England in the Eighteenth Century.

His great-niece was the child of a black slave and his sister's son, Sir John Lindsay. This is (...) also a narrative of the British Slave trade including some of Lord Mansfield's judgements at the King's Bench Division, Royal Courts of Justice. (shrink)

Hegel's lord-bondsman dialectic has been of especially great interest to progressive and radical Hegelians—broadly speaking, politically left-leaning interpreters of Hegel who object to certain social hierarchies and demand their abolition. They read Hegel as giving an account of how ‘lordship’ over others is an inherently unstable and unsatisfying social formation, even for its supposed beneficiaries. Marxists, feminists and post-colonial theorists have all found inspiration in Hegel's analysis of the lord and bondsman by applying it to concrete relations of oppression, such (...) as capitalism, patriarchy, or racism. In contrast, recent scholarship on Hegel's views on race and colonialism has cast doubt on whether his systematic political philosophy and philosophy of history can be of similar use to progressives. Hegel was undeniably a Eurocentric thinker, but philosophers like Robert Bernasconi and Alison Stone have convincingly shown that he was also a racist and a defender of colonialism. Crucially, however, few of the scholars who write on Hegel's pro-colonialism have analysed this feature of Hegel's thought in connection with the lord-bondsman dialectic. In this article, I argue for two connected theses. First, I argue that contrary to the hopes of some progressive defenders of Hegel, we cannot easily separate the lord-bondsman dialectic from Hegel's pro-colonialism. This is because Hegel himself appealed to the lord-bondsman dialectic to argue that colonial slavery educated its victims, and could therefore be temporarily justified. Second, I argue that this pro-colonial reading of the dialectic, though largely ignored by contemporary interpreters, was in fact recognized and embraced by a group of Hegelians in North America known as the St Louis Hegelians. They used the lord-bondsman dialectic as a basis for a qualified defence of pre-Civil War American slavery. (shrink)

This article informally presents a solution to the paradoxes of truth and shows how the solution solves classical paradoxes (such as the original Liar) as well as the paradoxes that were invented as counterarguments for various proposed solutions (“the revenge of the Liar”). This solution complements the classical procedure of determining the truth values of sentences by its own failure and, when the procedure fails, through an appropriate semantic shift allows us to express the failure in a classical two-valued language. (...) Formally speaking, the solution is a language with one meaning of symbols and two valuations of the truth values of sentences. The primary valuation is a classical valuation that is partial in the presence of the truth predicate. It enables us to determine the classical truth value of a sentence or leads to the failure of that determination. The language with the primary valuation is precisely the largest intrinsic fixed point of the strong Kleene three-valued semantics (LIFPSK3). The semantic shift that allows us to express the failure of the primary valuation is precisely the classical closure of LIFPSK3: it extends LIFPSK3 to a classical language in parts where LIFPSK3 is undetermined. Thus, this article provides an argumentation, which has not been present in contemporary debates so far, for the choice of LIFPSK3 and its classical closure as the right model for the truth predicate. In the end, an erroneous critique of Kripke-Feferman axiomatic theory of truth, which is present in contemporary literature, is pointed out. (shrink)

ABSTRACT: This chapter offers a revenge-free solution to the liar paradox (at the centre of which is the notion of Gestalt shift) and presents a formal representation of truth in, or for, a natural language like English, which proposes to show both why -- and how -- truth is coherent and how it appears to be incoherent, while preserving classical logic and most principles that some philosophers have taken to be central to the concept of truth and our use of (...) that notion. The chapter argues that, by using a truth operator rather than truth predicate, it is possible to provide a coherent, model-theoretic representation of truth with various desirable features. After investigating what features of liar sentences are responsible for their paradoxicality, the chapter identifies the logic as the normal modal logic KT4M (= S4M). Drawing on the structure of KT4M (=S4M), the author proposes that, pace deflationism, truth has content, that the content of truth is bivalence, and that the notions of both truth and bivalence are semideterminable.

In this paper, we do two things. First, we provide some support for adopting a version of the meaningless strategy with respect to the liar paradox, and, second, we extend that strategy, by providing, albeit tentatively, a solution to that paradox—one that is semantic, rather than logical.

One well known approach to the soritical paradoxes is epistemicism, the view that propositions involving vague notions have definite truth values, though it is impossible in principle to know what they are. Recently, Paul Horwich has extended this approach to the liar paradox, arguing that the liar proposition has a truth value, though it is impossible to know which one it is. The main virtue of the epistemicist approach is that it need not reject classical logic, and in particular the (...) unrestricted acceptance of the principle of bivalence and law of excluded middle. Regardless of its success in solving the soritical paradoxes, the epistemicist approach faces a number of independent objections when it is applied to the liar paradox. I argue that the approach does not offer a satisfying, stable response to the paradoxes—not in general, and not for a minimalist about truth like Horwich. (shrink)

In contrast to film, theater, and literature, audiences typically sing along with popular songs. This can encourage a first-person mode of engagement with the narrative content. Unlike mere spectators, listeners sometimes imagine acting out the content when it is recited in the first-person. This is a common mode of engaging with popular music. And it can be uniquely morally problematic. It is problematic when it involves the enjoyment of imaginatively doing evil. I defend a Moorean view on the issue: It (...) is wrong to enjoy evil whether real or merely fiction. I develop my position through an examination of the controversially song "Mind of a Lunatic" (1990) by the Houston based rap group Geto Boys. (shrink)

Pluralists maintain that there is more than one truth property in virtue of which bearers are true. Unfortunately, it is not yet clear how they diagnose the liar paradox or what resources they have available to treat it. This chapter considers one recent attempt by Cotnoir (2013b) to treat the Liar. It argues that pluralists should reject the version of pluralism that Cotnoir assumes, discourse pluralism, in favor of a more naturalized approach to truth predication in real languages, which should (...) be a desideratum on any successful pluralist conception. Appealing to determination pluralism instead, which focuses on truth properties, it then proposes an alternative treatment to the Liar that shows liar sentences to be undecidable. (shrink)

Throughout her work, Audre Lorde maintains that her self-preservation in the face of oppression depends on acting from the recognition and valorization of her feelings as a deep source of knowledge. This claim, taken as a portrayal of agency, poses challenges to standard positions in ethics, epistemology, and moral psychology. This article examines the oppositional agency articulated by Lorde’s thought, locating feeling, poetry, and the power she calls “the erotic” within her avowed project of self-preservation. It then explores the implications (...) of taking seriously Lorde’s account, particularly for theorists examining ethics and epistemology under nonideal social conditions. For situations of sexual intimacy, for example, Lorde’s account unsettles prevailing assumptions about the role of consent in responsibility between sexual partners. I argue that obligations to solicit consent and respect refusal are not sufficient to acknowledge the value of agency in intimate encounters when agency is oppositional in the way Lorde describes.

In this paper we offer a new argument for the existence of God. We contend that the laws of logic are metaphysically dependent on the existence of God, understood as a necessarily existent, personal, spiritual being; thus anyone who grants that there are laws of logic should also accept that there is a God. We argue that if our most natural intuitions about them are correct, and if they are to play the role in our intellectual activities that we take (...) them to play, then the laws of logic are best construed as necessarily existent thoughts -- more specifically, as divine thoughts about divine thoughts. We conclude by highlighting some implications for both theistic arguments and antitheistic arguments. (shrink)

The article critically examines the heuristic capacity and methods of using separate tools of Wittgenstein’s philosophical grammar to treat various semantic pathologies (paradoxes of Liar, Truth-Teller, etc.). According to Wittgenstein, philosophical confusion associated with the analysis of such semantic pathologies arises on the grounds of our intuitive faith that we are able to express in language any property that interests us. For instance, we believe that the property “to have a length of exactly one metre” can be meaningfully attributed to (...) any extended object. However, such a faith is fundamentally wrong, since an object like a standard metre, which plays an exclusive role as the criterion of length in our measuring practices based on the metric system, is an example of an extended object about which one can say neither that it is one metre long, nor that it is not one metre long. A correct understanding of the language-game concept shows that the criterion by which we form a set of objects that meet the standards established by the criterion cannot be described in the same way as objects of this set. Language-games using predicates of truth and falsehood are similar to our practice of measuring length using the metric system. In cases of Liar and Truth-Teller sentences, we encounter resembling examples of philosophical confusion. Beyond the context of their usage, “This sentence is false” and “This sentence is true” sentences seem to us paradoxes. But, according to Wittgenstein’s philosophical grammar, a correct method of treating such “paradoxical” sentences demands to find the lack- ing context for their usage, i.e. pay attention to the language-game in which they are emplloyed. Like in the case of the standard metre, we can claim that the sentence “This sentence is false” (“This sentence is true”) is neither false (true), nor not false (true). In an analogous way, Liar and Truth-Teller sentences should be interpreted as peculiar standards of falsehood and truth that we use in our language-games to judge about the truth value of other sentences.

This book is a fictionalized conversation in the form of dialogue between a devotee and Lord Krishna. Many current issues are analytically and critically discussed and debated providing an enlightening spirit and liberal attitude.

This chapter investigates the conflict between thought and speech that is inherent in lying. This is the conflict of saying what you think is false. The chapter shows how stubbornly saying what you think is false resists analysis. In traditional analyses of lying, saying what you think is false is analyzed in terms of saying something and believing that it is false. But standard cases of unconscious or divided belief challenge these analyses. Classic puzzles about belief from Gottlob Frege and (...) Saul Kripke show that suggested amendments involving assent instead of belief do not fare better. I argue that attempts to save these analyses by appeal to guises or Fregean modes of presentation will also run into trouble. I then consider alternative approaches to untruthfulness that focus on (a) expectations for one’s act of saying/asserting and (b) the intentions involved in one’s act of saying/asserting. Here I introduce two new kinds of case, which I call “truth serum” and “liar serum” cases. Consideration of these cases reveals structural problems with intention- and expectation-based approaches as well. Taken together, the string of cases presented suggests that saying what you think is false, or being untruthful, is no less difficult and interesting a subject for analysis than lying itself. Tackling the question of what it is to say what you think is false illuminates ways in which the study of lying is intertwined with fundamental issues in the nature of intentional action. (shrink)

It was Lord Northbourne who gifted to the world the term ‘organic farming’. His 1940 book Look to the Land is a manifesto of organic agriculture. In it he mooted a contest of “organic versus chemical farming” which he foresaw as a clash of world views that may last for generations. Northbourne’s ideas were foundational in launching the worldwide organics movement, and the book was a turning point in his own life. This biography relies on primary sources to draw a (...) picture of Lord Northbourne. He was a very shy man, a talented artist, a capable linguist, a keen sportsman and an Olympic silver medallist, a graduate and lecturer in agriculture of the University of Oxford, a lifelong farmer, he was profoundly spiritual, an accomplished author, and as a wordsmith he could be a compelling advocate for his cause as Look to the Land shows. His interest in biodynamics led him to visit Switzerland in 1939 to invite the leading advocate of the times, Dr Ehrenfried Pfeiffer, to present the first conference on biodynamic farming in Britain, and it was in the following year that Look to the Land appeared. Rather than the mechanics or the practices of organics, Northbourne’s book presents the philosophy, the rationale, and the imperative of organic farming. The ideas of his organics manifesto took on a life of their own and were quickly spread globally, with early uptakes in the USA and Australia. Meanwhile, while maintaining lifelong interests and commitments to agriculture and education, Northbourne became progressively more engaged with spiritual matters, and his subsequent writings reflect his growing interest in metaphysics. He translated books by leading perennialist authors Frithjof Schuon, René Guénon, and Titus Burckhardt. Northbourne led a full life, but it is Look to the Land that is his enduring ideological legacy. This biography examines: firstly, the book, its ideas, history, uptake and impact; secondly, Northbourne’s life before Look to the Land; and thirdly, his life after Look to the Land. (shrink)

The present paper investigates whether strictly classical inferences contribute to the formalization of (genuine) paradoxes within natural deduction. Tennant's criterion for paradoxicality relies on the generation of an infinite reduction sequence, which distinguishes genuine paradoxes from mere inconsistencies. His methodological conjecture posits that genuine paradoxes are never strictly classical and can be derived without classical inferences such as the Law of Excluded Middle, Dilemma, Classical Reductio, and Double Negation Elimination. -/- It appears that there were two reasons for Tennant's proposal (...) of the methodological conjecture. The one is that strictly classical inferences hinder the generation of an infinite reduction sequence and the other is that strictly classical inferences have no role in the formalization of genuine paradoxes. -/- This paper raises questions about these two reasons. Focusing on the liar paradox, it will be argued that strictly classical inferences do not interfere with the generation of an infinite reduction sequence and that the liar sentence may implicitly entail strictly classical inferences. Should this analysis hold, it would call into question not only Tennant’s motivation for advancing the methodological conjecture, but also challenge his contention that genuine paradoxes—exemplified by the liar paradox—are never constructed with reliance on strictly classical inferences.

Confronting the Liar Paradox is commonly viewed as a prerequisite for developing a theory of truth. In this paper I turn the tables on this traditional conception of the relation between the two. The theorist of truth need not constrain his search for a “material” theory of truth, i.e., a theory of the philosophical nature of truth, by committing himself to one solution or another to the Liar Paradox. If he focuses on the nature of truth (leaving issues of formal (...) consistency for a later stage), he can arrive at material principles that prevent the Liar Paradox from arising in the first place. I argue for this point both on general methodological grounds and by example. The example is based on a substantivist theory of truth that emphasizes the role of truth in human cognition. The key point is that truth requires a certain complementarity of “immanence” and “transcendence”, and this means that some hierarchical structure is inherent in truth. Approaching the Liar Paradox from this perspective throws new light on its existent solutions: their differences and commonalities, their purported ad-hocness, and the relevance of natural language and bivalence to truth and the Liar.

My replies to Errol Lord, Adam Pautz, and Peter Railton's commentaries on The Rationality of Perception (2017).

We describe the earliest occurrences of the Liar Paradox in the Arabic tradition. e early Mutakallimūn claim the Liar Sentence is both true and false; they also associate the Liar with problems concerning plural subjects, which is somewhat puzzling. Abharī (1200-1265) ascribes an unsatisfiable truth condition to the Liar Sentence—as he puts it, its being true is the conjunction of its being true and false—and so concludes that the sentence is not true. Tūsī (1201-1274) argues that self-referential sentences, like the (...) Liar, are not truth-apt, and defends this claim by appealing to a correspondence theory of truth. Translations of the texts are provided as an appendix. (shrink)

Stephen Barker presents a novel approach to solving semantic paradoxes, including the Liar and its variants and Curry’s paradox. His approach is based around the concept of alethic undecidability. His approach, if successful, renders futile all attempts to assign semantic properties to the paradoxical sentences, whilst leaving classical logic fully intact. And, according to Barker, even the T-scheme remains valid, for validity is not undermined by undecidable instances. Barker’s approach is innovative and worthy of further consideration, particularly by those of (...) us who aim to find a solution without logical revisionism. As it stands, however, the approach is unsuccessful, as I shall demonstrate below. (shrink)

This essay reconstructs the sophisticated views on free will and determinism of the nineteenth-century Hindu mystic Sri Ramakrishna and brings them into dialogue with the views of three western philosophers—namely, the Scottish Enlightenment philosopher Lord Kames and the contemporary analytic philosophers Saul Smilansky and Derk Pereboom. Sri Ramakrishna affirms hard theological determinism, the incompatibilist view that God determines everything we do and think. At the same time, however, he claims that God, in His infinite wisdom, has endowed ordinary unenlightened people (...) with the illusion of free will for the sake of their moral and spiritual welfare. Kames, I suggest, defends a theological determinist position remarkably similar to Sri Ramakrishna’s. However, I argue that Sri Ramakrishna’s mystical orientation puts him in a better position than Kames to explain why a loving God would implant in us the illusion of free will in the first place. I then show how certain aspects of the views of Smilansky and Pereboom resonate with those of Sri Ramakrishna. (shrink)

It seems that the most common strategy to solve the liar paradox is to argue that liar sentences are meaningless and, consequently, truth-valueless. The other main option that has grown in recent years is the dialetheist view that treats liar sentences as meaningful, truth-apt and true. In this paper I will offer a new approach that does not belong in either camp. I hope to show that liar sentences can be interpreted as meaningful, truth-apt and false, but without engendering any (...) contradiction. This seemingly impossible task can be accomplished once the semantic structure of the liar sentence is unpacked by a quantified analysis. The paper will be divided in two sections. In the first section, I present the independent reasons that motivate the quantificational strategy and how it works in the liar sentence. In the second section, I explain how this quantificational analysis allows us to explain the truth teller sentence and a counter-example advanced against truthmaker maximalism, and deal with some potential objections.

Prayer is not a psychoactive chant that may trigger a meditative mood or transfigure us into a mystic. It is a simple set of words that are metaphorically arranged which induces a state of being aware and conscious beyond the mundane. It makes an amendment between us and God and makes us to be aware of God, Its creation and the purpose of our existence. The Lords’ Prayer indeed conditions us to know the reality beyond the personality of the mind.

A reply to two responses to an earlier paper, "A Liar Paradox".

One recently proposed solution to the Liar paradox is the contextual theory of truth. Tyler Burge (1979) argues that truth is an indexical notion and that the extension of the truth predicate shifts during Liar reasoning. A Liar sentence might be true in one context and false in another. To many, contextualism seems to capture our pre-theoretic intuitions about the semantic paradoxes; this is especially due to its reliance on the so-called Revenge phenomenon. I, however, show that Super-Liar sentences (where (...) a Super-Liar sentence is a sentence which says of itself that it is not true in any context) generate a significant problem for Burge’s contextual theory of truth.

Some infamous memoirs have turned out to be chock-full of fibs. Should we care? Why not say—as many have—that all autobiography is fiction, that accurate memory is impossible, that we start lying as soon as we start narrating, and that it doesn’t matter anyway, since made-up stories are just as good as true ones? Because, well, every part of that is misleading. First, we don’t misremember absolutely everything; second, we have other sources to draw on; third, story form affects only (...) significance, not facts; fourth, fiction and nonfiction offer different affordances, benefits, and delights. And since we need both kinds of writing, we have to insist on honesty in memoir; we have to stop saying that everything is invention and that fibs don’t matter. If memoirs could never be trusted, who would still read them? In a world without truth, what exactly would we speak to power? (shrink)

This is the original English version of a paper that has been published only in Chinese translation. (For the published, Chinese version, see "透視悖論說謊者的幽默指南", in page 37-44 on 拒絕再Hea──真理與意義的追尋) The paper was originally written as a lecture given at the University of Macau in April 2010. The paper argues that humor is essentially a form of paradoxical deception.

The truth-functional hypothesis states that indicative conditional sentences and the material implication have the same truth conditions. Haze (2011) has rejected this hypothesis. He claims that a self-referential conditional, coupled with a plausible assumption about its truth-values and the assumption that the truth-functional hypothesis is true, lead to a liar’s paradox. Given that neither the self-referential conditional nor the assumption about its truth-values are problematic, the culprit of the paradox must be the truth-functional hypothesis. Therefore, we should reject it. In (...) this paper I argue that, contrary to what Haze thinks, the truth-functional hypothesis is not to blame. In fact, no liar’s paradox emerges when the truth-functional hypothesis is true; it emerges only if it is false. (shrink)
