The vast majority of putative solutions to the liar paradox face the infamous revenge problem. In recent work, however, Kevin Scharp has extensively developed an exciting and highly novel “inconsistency approach” to the paradox that, he claims, does not face revenge. If Scharp is right, then this represents a significant step forward in our attempts to solve the liar paradox. However, in this paper, I raise a revenge problem that faces Scharp's inconsistency approach.

In this paper I revisit an important response to the Moral Twin Earth (MTE) challenge: The Common Functional Role strategy (CFR). I argue that CFR is open to a revenge problem. MTE-cases allegedly show that two linguistic communities can be in genuine disagreement even when they are regulated by distinct families of properties. CFR provides a way to reconcile the intuition that the two communities are in genuine disagreement with the claim that the use of moral terms by both (...) communities is causally regulated by different families of properties. This is done by identifying a functional role that those families of properties both fulfill. Still, even if CFR is successful, its proponents need to face a serious revenge problem. Roughly, it could be that the families of properties that regulate each community are equally perfect realizers of the relevant higher-order functional state. I suggest that the proponent of CFR faces a dilemma: either CFR has controversial implications about first-order moral theory, or CFR needs to be coupled with substantive and parochial empirical/metaphysical assumptions to avoid those implications.

The paper offers a solution to the semantic paradoxes, one in which (1) we keep the unrestricted truth schema “True(A)↔A”, and (2) the object language can include its own metalanguage. Because of the first feature, classical logic must be restricted, but full classical reasoning applies in “ordinary” contexts, including standard set theory. The more general logic that replaces classical logic includes a principle of substitutivity of equivalents, which with the truth schema leads to the general intersubstitutivity of True(A) with A (...) within the language.The logic is also shown to have the resources required to represent the way in which sentences (like the Liar sentence and the Curry sentence) that lead to paradox in classical logic are “defective”. We can in fact define a hierarchy of “defectiveness” predicates within the language. Contrary to claims that any solution to the paradoxes just breeds further paradoxes (“revenge problems”) involving defectiveness predicates, there is a general consistency/conservativeness proof that shows that talk of truth and the various “levels of defectiveness” can all be made coherent together within a single object language.

The Revenge Problem threatens every approach to the semantic paradoxes that proceeds by introducing nonclassical semantic values. Given any such collection Δ of additional semantic values, one can construct a Revenge sentence:This sentence is either false or has a value in Δ.TheEmbracing Revengeview, developed independently by Roy T. Cook and Phlippe Schlenker, addresses this problem by suggesting that the class of nonclassical semantic values is indefinitely extensible, with each successive Revenge sentence introducing a new ‘pathological’ semantic value (...) into the discourse. The view is explicitly motivated in terms of the idea that every notion thatseemsto be expressible should, if at all possible,beexpressible. Extant work on the Embracing Revenge view has failed to live up to this promise, since the formal languages developed within such work are expressively impoverished. We rectify this here by developing a much richer formal language, and semantics for that language, and we then prove an extremely powerful expressive completeness result for the system in question.

It is “the received wisdom” that any intuitively natural and consistent resolution of a class of semantic paradoxes immediately leads to other paradoxes just as bad as the first. This is often called the “revenge problem”. Some proponents of the received wisdom draw the conclusion that there is no hope of any natural treatment that puts all the paradoxes to rest: we must either live with the existence of paradoxes that we are unable to treat, or adopt artificial and (...) ad hoc means to avoid them. Others (“dialetheists”) argue that we can put the paradoxes to rest, but only by licensing the acceptance of some contradictions (presumably in a paraconsistent logic that prevents the contradictions from spreading everywhere).

In contrast to the vast literature on retributive theories of punishment, discussions of private revenge are rare in moral philosophy. This paper reviews some examples, from both classical and recent writers, finding uncertainty and equivocation over the ethical significance of acts of revenge, and in particular over their possible resemblances, in motive, purpose or justification, to acts of lawful punishment. A key problem for the coherence of our ethical conception of revenge is the consideration that certain acts (...) of revenge may be just (at least in the minimal sense that the victim of revenge has no grounds for complaint against the revenger) and yet be generally agreed to be morally wrong. The challenge of explaining adequately why private revenge is morally wrong poses particular difficulty for purely retributive theories of punishment, since without invoking consequentialist reasons it does not seem possible adequately to motivate an objection to just and proportionate acts of revenge.

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

Revenge arguments purport to show that any proposed solution to the semantic paradoxes generates new paradoxes that prove that solution to be inadequate. In this paper, I focus on revenge arguments that employ the model-theoretic semantics of a target theory and I argue, contra the current revenge-theoretic wisdom, that they can constitute genuine expressive limitations. I consider the anti-revenge strategy elaborated by Field and argue that it does not offer a way out of the revenge (...) problem. More generally, I argue that the difference between ‘standard’ and ‘revenge’ paradoxes is ill-conceived and should be abandoned. This will contribute to show that the theories that provide a uniform account of truth and other semantic notions are the ones best equipped to avoid the paradoxes altogether—‘standard’ and ‘revenge’ alike. (shrink)

It is an assumption widely shared by both retributivists and anti-retributivists that revenge is a morally impermissible basis for inflicting harm. Retributivists have thus exercised great ingenuity in demonstrating that retribution is fundamentally different from revenge. But this is, I argue, to misconstrue the problem. The problem is rather to recognize the essential continuity between revenge and retribution, and to address the question whether there is a moral basis for the very idea of inflicting harm in response (...) to moral wrongdoing. I argue that the only plausible such moral justification is the defense of honor, and that the debate needs to be focused on the legitimacy of honor as a moral basis for punishment. (shrink)

The paradoxes of self-reference are genuinely paradoxical. The liar paradox, Russell’s paradox and their cousins pose enormous difficulties to anyone who seeks to give a comprehensive theory of semantics, or of sets, or of any other domain which allows a modicum of self-reference and a modest number of logical principles. One approach to the paradoxes of self-reference takes these paradoxes as motivating a non-classical theory of logical consequence. Similar logical principles are used in each of the paradoxical inferences. If one (...) or other of these problematic inferences are rejected, we may arrive at a consistent (or at least, a coherent) theory. In this paper I will show that such approaches come at a serious cost. The general approach of using the paradoxes to restrict the class of allowable inferences places severe constraints on the domain of possible propositional logics, and on the kind of metatheory that is appropriate in the study of logic itself. Proof-theoretic and model-theoretic analyses of logical consequence make provide different ways for non-classical responses to the paradoxes to be defeated by revenge problems: the redefinition of logical connectives thought to be ruled out on logical grounds. Non-classical solutions are not the “easy way out” of the paradoxes. (shrink)

According to the paradigm of adaptive rationality, successful inference and prediction methods tend to be local and frugal. As a complement to work within this paradigm, we investigate the problem of selecting an optimal combination of prediction methods from a given toolbox of such local methods, in the context of changing environments. These selection methods are called meta-inductive strategies, if they are based on the success-records of the toolbox-methods. No absolutely optimal MI strategy exists—a fact that we call the “ (...) class='Hi'>revenge of ecological rationality”. Nevertheless one can show that a certain MI strategy exists, called “AW”, which is universally long-run optimal, with provably small short-run losses, in comparison to any set of prediction methods that it can use as input. We call this property universal access-optimality. Local and short-run improvements over AW are possible, but only at the cost of forfeiting universal access-optimality. The last part of the paper includes an empirical study of MI strategies in application to an 8-year-long data set from the Monash University Footy Tipping Competition. (shrink)

Minimizing the costs that others impose upon oneself and upon those in whom one has a fitness stake, such as kin and allies, is a key adaptive problem for many organisms. Our ancestors regularly faced such adaptive problems (including homicide, bodily harm, theft, mate poaching, cuckoldry, reputational damage, sexual aggression, and the infliction of these costs on one's offspring, mates, coalition partners, or friends). One solution to this problem is to impose retaliatory costs on an aggressor so that the (...) aggressor and other observers will lower their estimates of the net benefits to be gained from exploiting the retaliator in the future. We posit that humans have an evolved cognitive system that implements this strategy – deterrence – which we conceptualize as a revenge system. The revenge system produces a second adaptive problem: losing downstream gains from the individual on whom retaliatory costs have been imposed. We posit, consequently, a subsidiary computational system designed to restore particular relationships after cost-imposing interactions by inhibiting revenge and motivating behaviors that signal benevolence for the harmdoer. The operation of these systems depends on estimating the risk of future exploitation by the harmdoer and the expected future value of the relationship with the harmdoer. We review empirical evidence regarding the operation of these systems, discuss the causes of cultural and individual differences in their outputs, and sketch their computational architecture.

Realism about material objects faces a variety of epistemological objections. Recently, however, some realists have offered new accounts in response to these long-standing objections; many of which seem plausible. In this paper, I raise a new objection against realism vis-à-vis how we could empirically come to know mind-independent essential properties for objects. Traditionally, realists hold kind-membership and persistence as bound together for purposes of tracing out an object’s essential existence conditions. But I propose kind-membership and persistence for objects can conceptually (...) come apart and function epistemologically distinctly from one another—in which case the usual reliance by realists on an assumption of persistence to determine kind-membership conditions is unjustified. Thus, present realist attempts to explain how empirical detection of mind-independent essential properties for objects could possibly occur inevitably results in circularity. The charge against the realist is to explain why we don’t have to first discover persistence conditions for an object before we can ascertain kind-membership conditions for an object. If no answer is forthcoming, then it seems the weight of the epistemological objection to realism is back in full force. (shrink)

Fregean theories of descriptions as terms have to deal with improper descriptions. To save bivalence various proposals have been made that involve assigning referents to improper descriptions. While bivalence is indeed saved, there is a price to be paid. Instantiations of the same general scheme, viz. the one and only individual that is F and G is G, are not only allowed but even required to have different truth values.

Liberal government, as analysed by Foucault, is a project of measured, utilitarian political activity, that takes ‘population’ as its object, dating back to the late 17th century. The rise of nationalism, authoritarianism and populism directly challenges this project, by seeking to re-introduce excessive, gratuitous and performative modes of power back into liberal societies. This article examines the relationship and tensions between government and sovereignty, so as to make sense of this apparent ‘revenge of sovereignty on government’. It argues that (...) neoliberalism has been a crucial factor in the return of sovereignty as a ‘problem’ of contemporary societies. Neoliberalism tacitly generates new centres of sovereign power, which have become publicly visible since 2008, leading to a dramatic resurgence of discourses and claims to ‘sovereignty’. (shrink)

According to ‘paracomplete’ theorists like Hartry Field, there are some sentences (such as sentences that attribute untruth to themselves) about which we should reject the relevant instances of the Law of the Excluded Middle without accepting their negations. The central alleged advantage of this approach over other consistent solutions to the Liar Paradox—for example, the view that Liars have some third truth-value other than ‘true’ or ‘false’—lies in its apparently superior ability to avoid ‘revenge paradoxes’. I argue, however, that (...) this advantage is illusory. The paracomplete theorist faces revenge problems of their own. (shrink)

Forgiveness and Revenge is a powerful exploration of our attitudes to serious wrongdoings and a careful examination of the values that underlie our thinking about revenge and forgiveness. From adulterous spouses to terrorist factions, we are surrounded by wrongdoing, yet we rarely agree which response is appropriate. The problem of how to respond realistically and sensitively to the wrongs of the past remains a perplexing one. Trudy Govier clarifies our thinking on this subject by examining the moral and (...) practical impact of revenge and forgiveness, both personal and political. Forgiveness and Revenge offers much-needed clarity and reason where emotions often prevail. It is essential reading for anyone interested in the ethics of attitudes to wrongdoing. (shrink)

A depraved conscience is the most destructive force in political life. J. Budziszewski incisively demonstrates that modern ideologies all deny the fallen nature that is the source of the three great problems of public life; we do wrong, our thinking about the wrong we do is clouded, and our efforts to rectify that wrong are themselves deformed by sin. Blinded to this truth about ourselves, we habitually suppress our conscience until it is corrupted and, taking its revenge, leads (...) us to cultural calamity. Describing the political effects of Original Sin, Dr. Budziszewski shows how man's suppression of his knowledge of right and wrong corrupts his conscience and accelerates social collapse. The depraved conscience grasps at the illusion of "moral neutrality", the absurd notion that men can live together without a shared understanding of how things are. The revenge of conscience is horrifically manifest today in abortion, euthanasia, and suicide, evils brought about by the pollution of good impulses such as pity, prudence, honor, and love. The way out of this confusion, he concludes, is a return to Christianity, whose troubling memory men now suppress along with their knowledge of natural law. (shrink)

Empirical results suggest that defocusing attention results in primary process or associative thought, conducive to finding unusual connections, while focusing attention results in secondary process or analytic thought, conducive to rule-based operations. Creativity appears to involve both. It is widely believed that it is possible to escape mental fixation by spontaneously and temporarily engaging in a more divergent or associative mode of thought. The resulting insight may be refined in a more analytic mode of thought. The question addressed here is: (...) how does the architecture of memory support these two modes of thought, and what is happening at the neural level when one shifts between them? Recent advances in neuroscience shed light on this. It was demonstrated that activated cell assemblies are composed of multiple ‘neural cliques’, groups of neurons that respond differentially to general or context-specific aspects of a situation. I refer to neural cliques that would not be included in the assembly if one were in an analytic mode, but would be if one were in an associative mode, as ‘neurds’. It is posited that the shift to a more associative mode of thought conducive to insight is accomplished by recruiting neurds that respond to abstract or atypical subsymbolic microfeatures of the problem or situation. Since memory is distributed and content-addressable this fosters remindings and the forging of creative connections to potentially relevant items previously encoded in those neurons. Thus it is proposed that creative thought involves neither randomness, nor search through a space of predefined alternatives, but emerges naturally through the recruitment of neurds. It is suggested this occurs when there is a need to resolve conceptual gaps in ones’ internal model of the world, and resolution involves context-driven actualization of the potentiality afforded by its fine-grained associative structure.

Most work on the semantic paradoxes within classical logic has centered around what this essay calls “linguistic” accounts of the paradoxes: they attribute to sentences or utterances of sentences some property that is supposed to explain their paradoxical or nonparadoxical status. “No proposition” views are paradigm examples of linguistic theories, although practically all accounts of the paradoxes subscribe to some kind of linguistic theory. This essay shows that linguistic accounts of the paradoxes endorsing classical logic are subject to a particularly (...) acute form of the revenge paradox: that there is no exhaustive classification of sentences into “good” and “bad” such that the T-schema holds when restricted to the “good” sentences unless it is also possible to prove some “bad” sentences. The foundations for an alternative classical nonlinguistic approach is outlined that is not subject to the same kinds of problems. Although revenge paradoxes of different strengths can be formulated, they are found to be indeterminate at higher orders and not inconsistent. (shrink)

“Spousal revenge” killers murder their child apparently out of a desire to cause harm to their ex-partner, the child’s other parent. Standard explanations of these killings fail to provide an adequate solution to what I call the problem of spousal revenge filicide. This is the problem of how a killer comes to take their rage at their former partner out on their own child and how that child can be dehumanized to the point of murder. Although the dehumanization (...) of the victim is acknowledged to occur, why it occurs is not well understood. Here, I offer an hypothesis that the killer fails to represent their child as a moral subject with a mind of their own. This is due to a deficit in the killer’s capacity for person perception which is, by hypothesis, pathological. As such, the killer experiences the child as an object, rather than a person, which is of significant emotional value to the other parent. The specificity of this disorder explains why the ex-partner themselves is not targeted, and it explains how the killer is able to understand that killing the child will harm the other parent.

The 2020 coronavirus pandemic is a phenomenon of great interest from the point of view of philosophy of technique. In this paper, we propose an interpretation of its causes and its current and foreseeable effects through a dual theoretical framework. On the one hand, we will use Edward Tenner’s concept of the revenge effect, which refers to the phenomenon by which a technique produces unexpected consequences that cancel its objective. In this case, modern mobility techniques, by spreading the disease (...) on a global scale, have produced the opposite effect, that is, the mobility limitations of lockdowns. On the other hand, we will embrace Jacques Ellul’s philosophy of technique, which shows how many problems produced by modern technique, such as the current pandemic, have an ultimate tendency toward the establishment of a centralized and authoritarian organization of humanity not compatible with the fundamental rights of liberal democracies. The conclusion drawn from these elements will be that the way the pandemic has been tackled supports Ellul’s prediction about the establishment of such an organization. (shrink)

In a series of recent publications, Jeffrey King (The nature and structure of content, 2007; Proc Aristot Soc 109(3):257–277, 2009; Philos Stud, 2012) argues for a view on which propositions are facts. He also argues against views on which propositions are set-theoretical objects, in part because such views face Benacerraf problems. In this paper, we argue that, when it comes to Benacerraf problems, King’s view doesn’t fare any better than its set-theoretical rivals do. Finally, we argue that his (...) view faces a further Benacerraf problem, one that threatens to undercut his explanation of why propositions have truth-conditions. If correct, our arguments undercut King’s main motivation for accepting his view over its rivals. (shrink)

Logical pluralism is the view that there is more than one correct logic. Most logical pluralists think that logic is normative in the sense that you make a mistake if you accept the premisses of a valid argument but reject its conclusion. Some authors have argued that this combination is self-undermining: Suppose that L1 and L2 are correct logics that coincide except for the argument from Γ to φ, which is valid in L1 but invalid in L2. If you accept (...) all sentences in Γ, then, by normativity, you make a mistake if you reject φ. In order to avoid mistakes, you should accept φ or suspend judgment about φ. Both options are problematic for pluralism. Can pluralists avoid this worry by rejecting the normativity of logic? I argue that they cannot. All else being equal, the argument goes through even if logic is not normative. (shrink)

In the introduction to our volume, we discuss the need for philosophical reflection on tourism as a cultural and human phenomenon. We give a brief account of the conference which was the starting point of the discussion and papers contained in this volume. We consider pressing social and environmental issues associated with the phenomenon of tourism, tracing its roots from antiquity to the present. Consideration of the peculiar connection between tourism and human behaviour, tourism and culture, provides insights into the (...) causes and possible solutions of problems arising from mass tourism, overtourism, “revenge tourism” in the post-pandemic world – problems of social justice, environmental protection, sustainability, economic and political security, human happiness and well-being. The journey of the tourist reveals itself as a journey of self-exploration and self-discovery in a world whose natural resources, biological and cultural diversity, and capacity to sustain humans’ pursuit of happiness and pleasure are fast diminishing. Despite the “breather” afforded by the global Covid-19 pandemic to all those engaged in the practice of tourism, whether as consumers or providers, lasting improvements have yet to be implemented. Instead, tourists and tourist providers everywhere are rushing to recoup their losses and make up for lost time. The papers in this volume examine crucial social, physical, psychological and cultural factors influencing tourism practice and their significance for the nurturing of human happiness and well-being, in order to help assure the preservation of the necessary conditions for life on earth.

Response-dependence theses are usually formulated in terms of a priori true biconditionals of roughly the form ‘something, x, falls under the concept ‘F’ ↔ x would elicit response R from subjects S under conditions C’.

Invoking a form of quantifier variance promises to let us explain mathematicians’ freedom to introduce new kinds of mathematical objects in a way that avoids some problems for standard platonist and nominalist views. In this paper I’ll note that, despite traditional associations between quantifier variance and Carnapian rejection of metaphysics, Siderian realists about metaphysics can naturally be quantifier variantists.

The author of the article contrasts the objection to transhumanism, which proceeds from the fact of success technoscience, with the objection, that takes the very fact of technoscience as a problem. Transhumanism itself gives rise to the problematization of science. It is the top of its development, and at the same time it fits into a single line of continuity of the forms of transformation of human nature known in history, as another, new link of it, following Christianity in this (...) serie. The identification of this kind of "religious" roots of transhumanism brings back the relevance of the problem of the connection between science and Christianity and provides additional resources for reviewing this problem today. The author of the article shows the connection between the problem of the mathematization (transformation) of nature, known even to the Eleatics, the new possibilities opened for it by Christianity, and the new European tradition of the I-cogito. The Cogito presented itself as a human nature transformed through union with God, as the very unit that Zeno had once sought, but never found. But while posing as something new to western european philosophy and thus defining its development, the cogito was not what it claimed to be. The transition from Descartes' pseudo-discoveries to Zeno's conclusions was inevitable. It has declared itself as a transition from classical epistemology to non-classical epistemology. In view of the fact that non-classics do not just indicate the failure of the classics, but call into question the very possibility of science, two paths open up: the way back or the way forward. The way back brings us back to the problem of the genesis of science, to a radical revision of its possibility. The way forward is the path of transhumanism as a rehabilitation of the pseudo-unity of the I-cogito in the new, extremely favorable conditions, when postmodernism has already abolished the polarization of the top and the bottom, the upper and the lower, that set the problem of unity.

In lieu of an abstract, here is a brief excerpt of the content:Eclecticism or Skepticism? A Problem of the Early EnlightenmentMartin MulsowEclecticism has its own logic.1 According to this logic, eclecticism is an attitude which seeks to free itself from sectarian doctrines and to achieve a more objective position above all such groups. However, many revolutions end by catching their own tails, and this attitude quickly deteriorates into the definition of just another sect, taking the original argument for eclecticism with (...) it. Germany’s self-styled “eclectic” philosophy found itself in just such a self-destructive phase at the beginning of the eighteenth century, the very point at which the concept was beginning to be used much more widely, as a recent comprehensive study by Michael Albrecht has demonstrated.2 Taking Albrecht’s observations as my basis, I wish to draw upon the example provided by two thinkers and some previously neglected material to consider in greater depth a problem which characterizes a part of the eclectic movement of the early German Enlightenment: the tense relationship between eclecticism and radical skepticism.3 [End Page 465]Jakob Friedrich Reimmann, SkepticAs a young man, Jakob Friedrich Reimmann, the great scholar and historian of philosophy and scholarship, was one of the most resolutely skeptical philosophers of the early Enlightenment.4 In an anonymous contribution to the eighth volume of the Observationes selectae, which appeared in 1704, Reimmann raises the question: was Solomon a skeptic?5 The anonymity which protected this article, as it did all others which appeared in Halle’s periodical,6 made it possible for Reimmann to experiment with unorthodox ideas, including some which had to do with the then-fashionable eclecticism. He could thus include such criticism of eclecticism as:[I]t is not so, as you say, that a distinction must be made between sectarians and eclectics. For it is possible to prove from induction that eclectics also disagree among themselves about knowledge of fundamentals, and that they do not agree among themselves any better than the clocks of a large town. What could be found wiser, what more pious, what better than the hypotheses of the Pyrrhonists?7Contemporary eclecticism, he asserted, was nothing other than a reproduction of the various individual sects because its own arguments mirrored their fundamental differences. Reimmann’s risky suggestion was that this eclecticism should be replaced by a pyrrhonism which would be better able to fulfil the original intentions of the “eclectic” philosophers. [End Page 466]Reimmann’s article has a somewhat cryptic relationship to Joachim Lange’s Medicina Mentis of 1704.8 Reimmann replies to this work without referring to it explicitly. Lange had written a history of philosophy as a history of corruption (a historia philomoriae, of the love of madness), according to which philosophy could only become blinder when, after the fall of Adam and the loss of Old Testament wisdom, it moved away from its origin. This argument was combined with an eclectic psychological logic in the style of Buddeus and Poiret. Reimmann is revenging himself for the “collubus,” that is, for Lange’s twisting of the ideas which Reimmann had discussed with him in confidence to portray them falsely as godless. The tensions between Thomasius and Lange, which increased after 1702, may also have played a role in the background. It is possible here to see the close contact and discussions which preceded the publication of books in Halle. From the safety of his anonymity Reimmann responds that it is ridiculous to try to sell the patriarchs as philosophers, but that, if one must do so, then Solomon can only be seen as a skeptic, if not a pyrrhonist. French libertines had already shocked the church with this assertion at the beginning of the seventeenth century,9 and it is significant that this tendency [End Page 467] reappears in the midst of the eclecticism of the early Enlightenment. Reimmann cites La Mothe le Vayer extensively.It seems logical, then, that Reimmann should have taken a critical position against Thomasian eclecticism as early as 1697 in his Schediasma philosophicum de Logices Aristotelicae, Rameae, Cartesianae & Electivae insufficientia.10 With Johann Jakob von Ryssel, a student of Thomasius, Reimmann develops the concept of “eclectic doubt”; his growing experience...

August Wilhelm von Schlegel, who did so much to rend the already torn artistic reputation of Euripides in the early nineteenth century, is singularly lenient in his criticism of the Hecuba. His adverse comment is limited to three points only: The first, that ‘the two actions of this piece—the sacrifice of Polyxena and the revenge on Polymestor on account of the murder of Polydorus—have nothing in common with each other but their connexion with Hecuba’; the second, that ‘the second (...) half destroys the soft impressions of the first in a highly repulsive manner’; and the third, that it is ‘not very suitable that Hecuba should display such presence of mind in her revenge.’ In this leniency he differs from one of the latest modern English critics, Professor G. Norwood,2 who does not hesitate to condemn the play as ‘on the whole poor and uninteresting,’ ‘far below the best of Euripides' work’; and from his great predecessor, J. J. Reiske, who condemned the play on ten distinct counts, all different from those that form the basis of SchlegeFs own argument. (shrink)

Conciliatory theories of disagreement face a revenge problem; they cannot be coherently believed by one who thinks they have peers who are not conciliationists. I argue that this is a deep problem for conciliationism.

Closure is the idea that what is true about a theory of truth should be true in it. Commitment to closure under truth motivates non-classical logic; commitment to closure under validity leads to substructural logic. These moves can be thought of as responses to revenge problems. With a focus on truth in mathematics, I will consider whether a noncontractive approach faces a similar revenge problem with respect to closure under provability, and argue that if a noncontractive theory (...) is to be genuinely closed, then it must be free of all contraction, even in the metatheory.

Truth values are, properly understood, merely proxies for the various relations that can hold between language and the world. Once truth values are understood in this way, consideration of the Liar paradox and the revenge problem shows that our language is indefinitely extensible, as is the class of truth values that statements of our language can take – in short, there is a proper class of such truth values. As a result, important and unexpected connections emerge between the semantic (...) paradoxes and the set-theoretic paradoxes. (shrink)

We show how in the hierarchies${F_\alpha }$of Fieldian truth sets, and Herzberger’s${H_\alpha }$revision sequence starting from any hypothesis for${F_0}$ that essentially each${H_\alpha }$ carries within it a history of the whole prior revision process.As applications we provide a precise representation for, and a calculation of the length of, possiblepath independent determinateness hierarchiesof Field’s construction with a binary conditional operator. We demonstrate the existence of generalized liar sentences, that can be considered as diagonalizing past the determinateness hierarchies definable in Field’s recent (...) models. The ‘defectiveness’ of such diagonal sentences necessarily cannot be classified by any of the determinateness predicates of the model. They are ‘ineffable liars’. We may consider them a response to the claim of Field that ‘the conditional can be used to show that the theory is not subject to “revenge problems”.’. (shrink)

A new solution to the liar paradox is developed using the insight that it is illegitimate to even suppose (let alone assert) that a liar sentence has a truth-status (true or not) on the grounds that supposing this sentence to be true/not-true essentially defeats the telos of supposition in a readily identifiable way. On that basis, the paradox is blocked by restricting the Rule of Assumptions in Gentzen-style presentations of the sequent-calculus. The lesson of the liar is that not all (...) assumptions are for free. One merit of this proposal is that it is free from the revenge problem. (shrink)

Consideration of a paradox originally discovered by John Buridan provides a springboard for a general solution to paradoxes within the Liar family. The solution rests on a philosophical defence of truth-value-gaps and is consistent (non-dialetheist), avoids ‘revenge’ problems, imports no ad hoc assumptions, is not applicable to only a proper subset of the semantic paradoxes and implies no restriction of the expressive capacities of language.

A syntactically correct number-specification may fail to specify any number due to underspecification. For similar reasons, although each sentence in the Yablo sequence is syntactically perfect, none yields a statement with any truth-value. As is true of all members of the Liar family, the sentences in the Yablo sequence are so constructed that the specification of their truth-conditions is vacuous; the Yablo sentences fail to yield statements. The ‘revenge’ problem is easily defused. The solution to the semantical paradoxes offered (...) here revives the mediaeval cassatio approach, one that largely disappeared due to its incomprehending rejection by influential contemporary writers such as William Shyreswood and Thomas Bradwardine. The diagnosis readily extends to the set-theoretic paradoxes. (shrink)

According to truthmaker maximalism, each truth has a truthmaker. Peter Milne has attempted to refute truthmaker maximalism on mere logical grounds via the construction of a self-referential truthmaker sentence M “saying” of itself that it doesn’t have a truthmaker. Milne argues that M turns out to be a true sentence without a truthmaker and thus provides a counterexample to truthmaker maximalism. In this paper, I show that Milne’s refutation of truthmaker maximalism does not succeed. In particular, I argue that the (...) notion of truthmaker meets two structural principles which, if added to a formal language of a theory, are already sufficient to produce a provable contradiction—a contradiction that gives rise to a socalled “Truthmaker paradox”. I also address the question of how to possibly resolve the Truthmaker paradox. I thereby show that the Truthmaker paradox, just as the strengthened Liar paradox, yields a “revenge problem” for paracomplete theories and might lead to triviality for Priest’s dialetheist account LP if the notion of truthmaker is defined as a certain semantic predicate within LP. But regardless of how one tries to cope with the Truthmaker paradox, this paradox is surely interesting in its own right. However, its significance is completely orthogonal to the question of whether truthmaker maximalism is a philosophically sound view. (shrink)

In this paper, I consider the question of whether or not the deflationist about truth can respond to the Liar and allied paradoxes by taking sentences such as the following: (1) (1) is false (2) (2) is not true (3) (3) is true to be meaningless. Let's call this strategy for dealing with the Liar and Liar-like phenomena the Meaningless Strategy. This strategy is intuitively satisfying: it captures many people's initial response to the paradoxes; and it is theoretically important: if (...) successful, it might allow the deflationist to avoid the revenge problem that plagues so many putative solutions to the Liar. Moreover, owing to the austerity of their theory, deflationists have very few resources to deploy in attempting to accommodate the Liar, which means that if the deflationist is in a good position to employ the Meaningless Strategy, so much the better for deflationism.

This paper offers an analysis of a hitherto neglected text on insoluble propositions dating from the late XiVth century and puts it into perspective within the context of the contemporary debate concerning semantic paradoxes. The author of the text is the italian logician Peter of Mantua (d. 1399/1400). The treatise is relevant both from a theoretical and from a historical standpoint. By appealing to a distinction between two senses in which propositions are said to be true, it offers an unusual (...) solution to the paradox, but in a traditional spirit that contrasts a number of trends prevailing in the XiVth century. It also counts as a remarkable piece of evidence for the reconstruction of the reception of English logic in italy, as it is inspired by the views of John Wyclif. Three approaches addressing the Liar paradox (Albert of Saxony, William Heytesbury and a version of strong restrictionism) are first criticised by Peter of Mantua, before he presents his own alternative solution. The latter seems to have a prima facie intuitive justification, but is in fact acceptable only on a very restricted understanding, since its generalisation is subject to the so-called revenge problem.

emantic pathologies of self-reference include the Liar (‘this sentence is false’), the Truth-Teller (‘this sentence is true’) and the Open Pair (‘the neighbouring sentence is false’ ‘the neighbouring sentence is false’). Although they seem like perfectly meaningful declarative sentences, truth value assignment to their uses seems either inconsistent (the Liar) or arbitrary (the Truth-Teller and the Open-Pair). These pathologies thus call for a resolution. I propose such a resolution in terms of relative-truth: the truth value of a pathological sentence use (...) varies with the context of its assessment. It always has a determinate truth value, but this truth value is relative to the context of its assessment. I start by considering a fairly esoteric pathology: the Truth-Teller, that is, sentences which assert nothing but their own truth. I make the case that truth value of a given truth-teller use must in general depend on the context of its assessment, and that one can indeed change its truth value at will. I then show how the notion of assessment-sensitive truth can help us provide solutions to other semantic paradoxes such as the Liar and the Open Pair and that those solutions are immune to revenge problems. I conclude by situating my proposal among the main approaches to the semantic paradoxes, and by drawing a very broad moral about pathological self-reference and intentionality. (shrink)

I argue that a new solution to the semantic paradoxes is possible based on truth-making. I show that with an appropriate understanding of what the ultimate truth and falsity makers of sentences are, it can be demonstrated that sentences like the liar are alethically undecidable. That means it cannot be said in principle whether such sentences are true, not true, false, not-false, neither true nor false, both true and false, and so on. I argue that this leads to a solution (...) to the semantic paradoxes that appears to be free of revenge problems, allows us to maintain classical logic and the validity of the T-schema. (shrink)
