This paper investigates the relationship between two evaluative claims about agents’ de- grees of belief: (i) that it is better to have more, rather than less accurate degrees of belief, and (ii) that it is better to have less, rather than more probabilistically incoherent degrees of belief. We show that, for suitable combinations of inaccuracy measures and incoherence measures, both claims are compatible, although not equivalent; moreover, certain ways of becoming less incoherent always guarantee improvements in accuracy. Incompatibilities between (...) particular incoherence and inaccuracy measures can be exploited to argue against particular ways of measuring either inaccuracy or incoherence. (shrink)

Incoherence is usually regarded as a bad thing. Incoherence suggests irrationality, confusion, paradox. Incoherentism disagrees: incoherence is not always a bad thing, sometimes we ought to be incoherent. If correct, Incoherentism has important and controversial implications. It implies that rationality does not always require coherence. Dilemmism and Incoherentism both embrace conflict in epistemology. After identifying some important differences between these two ways of embracing conflict, I offer some reasons to prefer Incoherentism over Dilemmism. Namely, that Incoherentism allows (...) us to deliberate about what we ought to believe using ordinary epistemology, and it does a better job of accommodating the positive features of incoherence.

In lieu of an abstract, here is a brief excerpt of the content:The Incoherence of Determining Death by Neurological Criteria: A Commentary on Controversies in the Determination of Death, A White Paper by the President’s Council on Bioethics*Franklin G. Miller** (bio) and Robert D. Truog (bio)Traditionally the cessation of breathing and heart beat has marked the passage from life to death. Shortly after death was determined, the body became a cold corpse, suitable for burial or cremation. Two technological changes (...) in the second half of the twentieth century prompted calls for a new, or at least expanded, definition of death: the development of intensive care medicine, especially the use of mechanical ventilators, and the advent of successful transplantation of vital organs. Patients with profound neurological damage, leaving them incapable of breathing on their own and in an irreversible coma, could be maintained for some period of time with the aid of mechanical ventilation. The situation of these patients posed two ethical questions. Is it appropriate to stop life-sustaining treatment? If so, is it acceptable to retrieve vital organs for transplantation to save the lives of others before stopping treatment?In 1968, the Ad Hoc Committee of the Harvard Medical School to Examine the Definition of Brain Death proposed that death could be determined on the basis of neurological criteria, thus providing a positive answer to these two questions (Ad Hoc Committee 1968). According to the position of this committee, patients diagnosed with the cessation of brain function are dead, despite the fact that they breathe and circulate blood with the aid of mechanical ventilation. [End Page 185] Because they are dead, it is appropriate, indeed imperative, to stop mechanical ventilation. And because they are dead, it becomes ethical to procure vital organs for transplantation before stopping what otherwise would be life-sustaining treatment. Remarkably, this innovative neurological determination of death became, with little debate or controversy, the established position in medical ethics and the law throughout the United States.The Harvard Committee articulated the diagnosis of “irreversible coma,” but merely asserted that this condition constituted death. No explanatory rationale was provided. It fell to the President’s Commission for the Study of Ethical Problems in Medicine and Biomedical and Behavioral Research to provide an authoritative rationale in its 1981 report, Defining Death. The second paragraph of the report set the stage as follows: “The question addressed here is not inherently difficult or complicated. Simply, it is whether the law ought to recognize new means for establishing that the death of a human being has occurred” (President’s Commission 1981, p. 3). The Commission claimed that “death is a unitary phenomenon” (p. 7) and that the determination of death by neurological criteria, in terms of the absence of all brain function, is consistent with the traditional conception of death as the cessation of vital functioning of the organism as a whole. The key issue is the integrative functioning of the human organism, which ceases to exist, according to the Commission, when the whole brain, including higher cortical areas and the brain stem, fails to function. Although “brain-dead” patients do not appear to be dead—i.e., the reality of their death is “masked” by the activity of mechanical ventilation—the patient’s body has irreversibly lost all capacity for integrative functioning. In the words of the Commission: “When artificial means of support mask this loss of integration as measured by the old methods [cessation of respiration and heart beat], brain-oriented criteria and tests provide a new window on the same phenomenon” (p. 33). The President’s Commission was instrumental in developing and establishing “The Uniform Definition of Death Act”: “An individual who has sustained either (1) irreversible cessation of circulatory and respiratory functions, or (2) irreversible cessation of all functions of the entire brain, including the brain stem, is dead” (p. 2).Although the question posed by the President’s Commission was easy to articulate, the answer, over time, has proved complicated and controversial. The coherence and cogency of determining death by neurological criteria has been challenged. Various experts have demonstrated that “brain-dead” patients maintained on mechanical ventilation display a range of vital, integrative, functioning, which conflicts with the judgment that they are dead (Truog and...

Panpsychism is now a bona fide potential solution to the metaphysical quandary of consciousness. Much of the debate concerning the viability of panpsychism is centered on the combination problem. Intriguingly, the literature analyzing this problem displays two competing interpretations which differ in their modal force. According to the first, which we call the ‘no-necessitation view', CP consists in the absence of a priori necessitation of macro-level phenomenal facts from micro-level phenomenal facts. In contrast, the second interpretation, which we label the (...) ‘incoherence charge’, goes further by insisting that it can be positively demonstrated that micro-experiences cannot combine to yield integral macro-experiences. While conceivability arguments are vulnerable to debates over conflicting intuitions, as well as to the claim that a more complete picture will grant the desired necessitation, IC has the advantage that, if true, it removes these concerns and approaches a more final verdict. Nevertheless, while conceivability arguments are widely discussed IC has not been equally well understood or recognized. In this paper we conduct a systematic investigation and reevaluation of IC, as it applies to constitutive micropsychism. We argue that the problem is real and therefore that constitutive micropsychism is a blind alley. (shrink)

Recent work on quantum gravity suggests that neither spacetime nor spatiotemporally located entites exist at a fundamental level. The loss of both brings with it the threat of empirical incoherence. A theory is empirically incoherent when the truth of that theory undermines the empirical justification for believing it. If neither spacetime nor spatiotemporally located entities exist as a part of a fundamental theory of QG, then such a theory seems to imply that there are no observables and so no (...) way that the theory can be confirmed. The threat of empirical incoherence can be addressed by treating spacetime and spatiotemporally located entities as emergent. The question then arises as to what the metaphysical nature of this emergence might be. In this paper, I explore a functionalist approach to this kind of emergence in the context of loop quantum gravity. I begin by rehearsing the spacetime functionalist’s account of emergence, clarifying the view along the way. I proceed to sketch out a functionalist treatment of spatiotemporally located entities and combine the two forms of functionalism into a double functionalism, according to which both spacetime and matter have the same functional realisers.

The incoherence is between Whitehead’s definition of “speculative philosophy” in the first section of Process and Reality's opening chapter which defines metaphysics as transcendental and important moments in later chapters of the book, where he asserts that metaphysical formulations are generalizations of empirical or contingent features. In explicating this inconsistency, the article attends to Whitehead’s definition of metaphysical in distinction from cosmological features, his understandings of the “aeroplane” metaphor, the ontological principle, and especially the initial aim. The article argues (...) that Whitehead’s account of these, and especially the initial aim, should be deleted from neoclassical metaphysics. (shrink)

I consider two possible evidentialist responses to Schmidt. According to the first, all of the reason-giving work in the relevant cases is being done by evidence. According to the second, even if the ‘incoherence fact’ sometimes provides a reason, what it provides a reason for is not a doxastic attitude, or at least not one that is an alternative to belief. I argue that the first response is not satisfying, but the second is defensible.

In this paper, we explore how we should aggregate the degrees of belief of a group of agents to give a single coherent set of degrees of belief, when at least some of those agents might be probabilistically incoherent. There are a number of ways of aggregating degrees of belief, and there are a number of ways of fixing incoherent degrees of belief. When we have picked one of each, should we aggregate first and then fix, or fix first and (...) then aggregate? Or should we try to do both at once? And when do these different procedures agree with one another? In this paper, we focus particularly on the final question. (shrink)

In this paper I draw apart two different contexts of Freirean pedagogical practice that I label interactional and institutional. The interactional refers to the immediate learning environment with relation to the interaction between the students and the teacher. In contrast, the institutional refers to how the institutions of education are managed, constructed, and organised and how they relate to the individuals those institutions are composed of. I begin by presenting a brief overview of Freire’s argument in favour of a revolutionary (...) pedagogy. I then highlight how this project is represented at both interactional and institutional levels with a particular focus upon the practice of the revolutionary leaders and their role in the development of the humanisation of the oppressed. In presenting the interactional and institutional elements of Freire’s pedagogy separately the tension between the individual and the state is made plain and the limitations of his politico-educational project are drawn out. I argue that due to an inconsistent application of the relationship between means and ends in Freire’s politico-educational project an incoherence between the interactional and institutional levels of education is highlighted. In responding to this limitation of Freire’s politico-educational project with a thoroughly interconnected relationship of means and ends I show that there remains a necessary conflict between the interests of the individual and the state. As a result of this a door is opened for the development of an argument in favour of the disestablishment of education and state from a Freirean perspective. (shrink)

Incoherence arguments are intended to demonstrate that some philosophical position should be rejected because it is fatally flawed. I review the kinds of fatal flaws targeted in incoherence arguments, and argue that such arguments are not conclusive against the position they target, but merely pose challenges that require greater imagination. Furthermore, I claim that apparently incoherent positions have an instrumental value in expanding the intellectual resources of philosophy.

Eva Schmidt argues that facts about incoherent beliefs can be non-evidential epistemic reasons to suspend judgment. In this commentary, I argue that incoherence-based reasons to suspend are epistemically superfluous: if the subjects in Schmidt’s cases ought to suspend judgment, then they should do so merely on the basis of their evidential reasons. This suggests a more general strategy to reduce the apparent normativity of coherence to the normativity of evidence. I conclude with some remarks on the independent interest that (...) reasons-first epistemology might have within an evidentialist framework. (shrink)

J.J.C. Smart famously complained that rule utilitarianism is incoherent, and that rule utilitarians are guilty of rule worship . Much has been said about whether Smart’s complaint is justified, but I will assume for the sake of argument that Smart was on to something. Instead, I have three other goals. First, I want to show that Smart’s complaint is a specific instance of a more general objection to a moral theory—what I will call the Incoherence Objection. Second, I want (...) to illustrate how the Incoherence Objection can apply both to consequentialist and, surprisingly, some nonconsequentialist theories. Finally, I want to demonstrate at least one way nonconsequentialist theories that make use of rules, principles, and the like can dodge the Incoherence Objection. (shrink)

The modern Everett interpretation of quantum mechanics describes an emergent multiverse. The goal of this paper is to provide a perspicuous characterisation of how the multiverse emerges making use of a recent account of (weak) ontological emergence. This will be cashed out with a case study that identifies decoherence as the mechanism for emergence. The greater metaphysical clarity enables the rebuttal of critiques due to Baker (2007) and Dawid and Th\'ebault (2015) that cast the emergent multiverse ontology as incoherent; responses (...) are also offered to challenges to the Everettian approach from Maudlin (2010) and Monton (2013).

Of the many possible, and no doubt actual, forms of incoherence covered by my title, I shall be concerned with only one, and must begin by dismissing the others. The incoherence I shall speak of is not any alleged inconsistency between deterministic and indeterministic physical theories , such as between classical particle mechanics and quantum theory. It is an inconsistency internal to determinism. Not, that is, internal to any deterministic theory ; but to the general claims put forward (...) by determinists—whether scientists, philosophers, or laymen. Still another qualification—it is ‘hard’ determinism I shall be concerned with—‘hard’ in the sense in which William James distinguished between hard and soft determinism. Soft determinism James himself ridiculed as glaringly incoherent, and in any case I shall not be specially concerned with determinism as regards human conduct—with the problem of free will and responsibility.

Brad Hooker; II*—Rule-Consequentialism, Incoherence, Fairness1, Proceedings of the Aristotelian Society, Volume 95, Issue 1, 1 June 1995, Pages 19–36, https://d.

For a long time many philosophers felt the incoherence objection was a decisive objection to rule-consequentialism, but that position has recently become less secure, because Brad Hooker has offered a clever new way for rule-consequentialists to avoid the incoherence objection. Hooker’s response defeats traditional forms of the incoherence objection, but this paper argues that another version of the problem remains. Several possible solutions fail. One other does not, but it introduces other problems into the theory. I conclude (...) that the new incoherence objection still poses a major challenge to rule-consequentialism, though not for the reasons usually assumed. It does not constitute a fatal objection to rule-consequentialism but instead highlights a theoretical drawback in the theory which must be taken into account during a more holistic evaluation of rule-consequentialism and its rivals.

SummarySubjecting to a detailed analysis Kant's diagnosis of dialectical error in the Transcendental Dialectic of the first Critique, the author posits that Kant's understanding of such error is, to the extent that it conflates the subjective‐objective, phenomenal‐noumenal, and regulative‐constitutive distinctions, fundamentally incoherent. The author argues not only that these three distinctions cannot on Kant's own terms be conflated, but also that Kant's treatment of dialectical error is further vitiated by circularity of argument: Kant proposes to explain the three distinctions by (...) means of the notion of transcendental error, which however the distinctions themselves were supposed to explain in the first place. After showing that Kant's diagnosis of dialectical error cannot be salvaged even by resorting to the Kantian concept of “transcendental subreption”, the author concludes that unless Kant could in some other way spell out the minimal conditions for dialectical error, Kant's very distinction between understanding and reason becomes difficult to justify.

In so-called garden-path jokes, an initial semantic representation is violated, and semantic revision reestablishes a coherent representation. 48 jokes were manipulated in three conditions: (i) a coherent ending, (ii) a joke ending, and (iii) a discourse-incoherent ending. A reading times study ( N = 24) and three studies with recordings of ERP and pupil changes ( N = 21, 24, and 24, respectively) supported the hypothesized cognitive processes. Jokes showed increased reading times of the final word compared to coherent endings. (...) ERP data mainly indicated semantic integration difficulties (N400). Larger pupil diameters to joke endings presumably reflect emotional responses. ERP evidence for increased discourse processing efforts and emotional responses, as assumed to be reflected in modulations of the late left anterior negativity (LLAN) and in an enhanced late frontal positivity (fP600), respectively, remains however incomplete. Processing of incoherent endings was also accompanied by increased reading times, a stronger and sustained N400, and context-sensitive P600 effects. Together, these findings provide evidence for a sequential, non-monotonic, and incremental discourse comprehension of garden-path jokes. (shrink)

Probabilism is the view that a rational agent's credences should always be probabilistically coherent. It has been argued that Probabilism follows, given the assumption that an epistemically rational agent ought to try to have credences that represent the world as accurately as possible. The key claim in this argument is that the goal of representing the world as accurately as possible is best served by having credences that are probabilistically coherent. This essay shows that this claim is false. In certain (...) cases, the goal of having accurate credences is best served by being probabilistically incoherent. Assuming that an epistemically rational agent ought to try to have credences that are as accurate as possible, it follows that in certain cases a rational agent ought to have probabilistically incoherent credences.

In his Just and Unjust Wars, Michael Walzer claims that his theory of just war is based on the rights of individuals to life and liberty. This is not the case. Walzer in fact bases his theory of jus ad bellum on the supreme rights of supra-individual political communities. According to his theory of jus ad bellum, the rights of political communities are of utmost importance, and individuals can be sacrificed for the sake of these communal rights. At the same (...) time, Walzer bases his theory of jus in bello on the supreme rights of individuals to life and liberty. According to his theory of jus in bello, the rights of individuals are of utmost importance, and political communities can never permissibly violate them in war. Thus, Walzer’s theory of just war is based on two incompatible theories of justice. This explains why Walzer’s theory produces incoherent practical prescriptions in cases of supreme emergencies. Furthermore, it is impossible for Walzer to base his theory of jus ad bellum on the rights of individuals as he conceives them. The theory of jus ad bellum holds that soldiers are obligated to obey the commands of their political superiors. However, this obligation violates the rights of individuals in a number of respects. This is why Walzer does not base the theory of jus ad bellum on individual rights, and produces an incoherent theory. (shrink)

We focus in this paper on the potential uses of Ludics, a logical framework based on recent developments in proof theory, for modeling natural language dialogues. The aim is to be able to grasp and to account for some aspects of incoherence in discourses. Among the properties relevant for studying dialogues, two features of Ludics are of interest for our purpose: the duality of viewpoints of two interlocutors as well as the possibility of ruptures. We illustrate first the potential (...) usefulness of such a model for accounting and analyzing incoherence in dialogues due to cultural gap. We then focus on dialogues with schizophrenic individuals to try to answer the following questions: to what extent does incoherence play a role in schizophrenic discourse? And, would a more precise characterization of “non-standard” rationality help explain the range of potential complications of schizophrenia? (shrink)

L’acceptabilité sociale fait référence aux échelons d’acceptation sociale accordée par les communautés et les autres parties prenantes à une entreprise, un projet ou une activité.

This paper presents a counterexample to the principle that all epistemic reasons for doxastic attitudes towards p are provided by evidence concerning p. I begin by motivating and clarifying the principle and the associated picture of epistemic reasons, including the notion of evidence concerning a proposition, which comprises both first- and second-order evidence. I then introduce the counterexample from incoherent doxastic attitudes by presenting three example cases. In each case, the fact that the subject’s doxastic attitudes are incoherent is an (...) epistemic reason to suspend, which is not provided by evidence. I argue that this incoherence fact is a reason for the subject to take a step back and reassess her evidence for her conflicting attitudes, and thus a reason to suspend all of them. Suspending judgment enables the subject to revise attitudes where appropriate and thus (typically) to arrive at a set of coherent and well-supported attitudes. I then address a dilemma for my proposal and, in conclusion, briefly suggest a picture of epistemic reasons on which they are to be understood against the background of the subject’s virtuous intellectual conduct.

There has recently been an expansion of anti-abortion measures in the United States. Within these various measures there is a divide over certain exceptions: some States permit abortion for pregnancies caused by rape while other States do not. This paper explores the underlying moral justification for such exceptions. I argue that within the dominant moral framework for reproductive ethics these exceptions are incoherent by their own lights. But this is not a defense of an exceptionless anti-abortion position. Rather, because the (...) typical way of making such exceptions is incoherent, this shows why the anti-abortion movement is dangerous: as these incoherencies are acknowledged, this may lead to ever stricter measures being put in place. I end by suggesting that those who are sympathetic to these exceptions should find it easier to move to a pro-choice position rather than to a more extreme, exceptionless one. (shrink)

In this paper, we ask: how should an agent who has incoherent credences update when they learn new evidence? The standard Bayesian answer for coherent agents is that they should conditionalize; however, this updating rule is not defined for incoherent starting credences. We show how one of the main arguments for conditionalization, the Dutch strategy argument, can be extended to devise a target property for updating plans that can apply to them regardless of whether the agent starts out with coherent (...) or incoherent credences. The main idea behind this extension is that the agent should avoid updating plans that increase the possible sure loss from Dutch strategies. This happens to be equivalent to avoiding updating plans that increase incoherence according to a distance-based incoherence measure. (shrink)

In this paper I am primarily interested in establishing that a coherence theory of truth is conceptually incoherent.

Habermas proposes a new solution to the problematic relation between republican values and democracy. He asserts that a new model of social cohesion is needed and he suggests that the sense of community in a democratic society should be founded exclusively on the acceptance and support of a system of constitutionally established rules which are the logical result of the historical evolution of constitution-making. He argues that an account of the constitutional process which led to the formation of the modern (...) republican state should provide the criteria for a rational set of norms which will exclude nationalism from the political arena. In this article, I point out the democratic hazards and the internal incoherence of Habermass alternative to the national state and I argue that a theoretical substitute should consider the existence of national identities as one of the aspects of modern pluralistic society.

Before God created did God have ideas in mind for particular things, kinds of things, properties of things, particular events, and laws of nature? At least since Augustine, theists have proposed differing answers. This paper is about a relatively recent theory, which holds that God constructs them when he creates the universe. James Ross, Brian Leftow, and Hugh McCann are its primary advocates. Since the shared features of their views do not pertain to the so-called “abstract objects” or to the (...) “necessary truths” of mathematics and logic, let us call this “divine possibility constructivism”, differentiating it from the theistic activism of Christopher Menzel and Thomas Morris and from the voluntarism of René Descartes—both of which could otherwise be construed as “constructivist”. According to Ross, Leftow, and McCann, God had nothing in mind before he created—which is to say that, before God created, God was not aware of possibilities for a universe. Rather, God’s being aware of any such possibilities is grounded only in God’s having constructed them ex nihilo. This paper shows that DPC is incoherent. (shrink)

ABSTRACT An influential argument against the possibility of obligations to oneself states that the very notion of such obligations is incoherent: If there were such obligations, we could release ourselves from them; yet releasing oneself from an obligation is impossible. I challenge this argument by arguing against the premise that it is impossible to release oneself from an obligation. I point out that this premise assumes that if it were possible to release oneself from an obligation, it would be impossible (...) to violate that obligation. I note that there are two interpretations of this assumption, one conceptual and one psychological. I argue that, on both interpretations, the assumption is false—at least according to independently plausible accounts of obligations to oneself and of what it means to waive an obligation. My arguments paint a picture of obligations to oneself that not only challenges the argument against their coherence, but also illuminates these obligations’ relationship to other parts of the moral domain.

Stojnić holds the radical view that coherence relations determine the reference of context-sensitive language. I argue against this from the theoretical perspective presented in Overlooking Conventions (2021). Theoretical interest in language comes from an interest in thoughts and their communication. A language is a system of symbols, constituted by a set of governing rules, used (inter alia) to communicate the meanings (contents) of thoughts. Thought meanings, hence speaker meanings, are explanatorily prior to semantic meanings. So, we start our consideration of (...) the theoretical place of coherence by considering the bearing of coherence on thought meanings. The paper argues that a person can have any thought at all, however incoherent. So, a thought’s meaning is independent of its coherence. Any thought can be expressed in an utterance. The semantic meaning of any utterance governed by the linguistic rules will be the meaning of the thought it expresses. So, the utterance’s meaning is independent of its coherence. The paper concludes that coherence has no place in the theory of meaning or reference. Nonetheless, it has a place in the theory of communication. I suspect that the error exemplifi es the widespread confusion of the metaphysics of meaning with the epistemology of interpretation. (shrink)

Kantian and commonsense moral thinking are incoherent because self‐other asymmetry does not cogently combine with the belief that we owe more to people the closer they are to us in familial or personal terms. The latter is commonsensically explained by the claim that it is natural or inevitable that we should care about those closer to us more than about those less close to us, but this seemingly plausible assumption tends to undercut the justification that is typically and intuitively offered (...) for self‐other asymmetry, namely, that we naturally care more about ourselves than about others, so that there is no need to assume any duty to avoid harming oneself. A commonsense ethics of virtue avoids this and other incoherences or tensions in Kantian and commonsense moral thinking. (shrink)

In a narrow sense of ‘disagreement,’ you and I disagree iff we believe inconsistent propositions. But there are numerous cases not covered by this definition that seem to constitute disagreements in a wider sense: disagreements about what to do, disagreements in attitude, disagreements in credence, etc. This wider sense of disagreement plays an important role in metaethics and epistemology. But what is it to disagree in the wider sense? On the view I’ll defend, roughly, you and I disagree in the (...) wide sense iff we hold attitudes that it would be incoherent for a single individual to hold. I’ll argue that this captures the relevant cases, and explore the consequences for metaethical debates between expressivists and contextualists. My view has two broader upshots: that coherence is a theoretically important property, and that an apparently descriptive question—are two subjects disagreeing?—turns on a normative one—are their attitudes jointly incoherent?

Although Abu Hamid Muhammad al-Ghazali lived a relatively short life, he established himself as one of the most important thinkers in the history of Islam. _The Incoherence of the Philosophers_, written after more than a decade of travel and ascetic contemplation, contends that while such Muslim philosophers as Avicenna boasted of unassailable arguments on matters of theology and metaphysics, they could not deliver on their claims; moreover, many of their assertions represented disguised heresy and unbelief.

It is argued that certain quantum theories of gravity — string theory, loop quantum gravity, non-commutative field theory — do not include spacetime as part of their fundamental ontology. There is a concern in the literature that theories of this kind are physically opaque and empirically incoherent.

Whereas the content of this paper centres on the disappearance and re-emergence of spacetime in quantum gravity, much of the (...) philosophical work centres more generally on issues of (emergent) ontology and how this ontology can be extracted from formal theories, the role of formal derivations in justifying ontological relations, the nature of Kuhnian revolutions, and the application of these revolutions to quantum gravity.

The most common way of dealing with the fear of death is denying death. Such denial can take two and only two forms: strategy 1 denies the finality of death; strategy 2 denies the reality of the dying subject. Most religions opt for strategy 1, but Buddhism seems to be an example of the 2nd. All variants of strategy 1 fail, however, and a closer look at the main Buddhist argument reveals that Buddhism in fact does not follow strategy 2. (...) Moreover, there is no other theory that does, and neither can there be. This means that there is no tenable theory that denies death. There may be no universally psychologically acceptable alternative, however, which would mean that if denying death is incoherent, this is an unavoidable incoherence. (shrink)

This article revisits some of the main tenets and problems of the Just Peace concept as developed in the German Protestant Church, showing how it is beset by incoherences, ironical returns of expanded violence, as well as the problem of abstraction: once the Just Peace concept is applied to concrete problems, it runs dry. The article then examines some recent contributions made under the wider umbrella of ‘peace ethics’, showing that attempts to combine the Just Peace and bellum iustum are (...) bound to fail. It then retraces the present shift to Just War thinking that reorders the basic terms, whilst also retaining some of the tenets of the Just Peace approach. Some refinements of these developments are indicated. (shrink)

A strength of liberal political institutions is their ability to accommodate pluralism, both allowing divergent comprehensive doctrines as well as constructing the common ground necessary for diverse people to live together. A pressing question is how far such pluralism extends. Which comprehensive doctrines are simply beyond the pale and need not be accommodated by a political consensus? Rawls attempted to keep the boundaries of reasonable disagreement quite broad by infamously denying that political liberalism need make reference to the concept of (...) truth, a claim that has been criticized by Joseph Raz, Joshua Cohen, and David Estlund. In this paper, we argue that these criticisms fail due to the fact that political liberalism can remain non-committal on the nature of truth, leaving the concept of truth in the domain of comprehensive doctrines while still avoiding the issues raised by Raz, Cohen, and Estlund. Further substantiating this point is the fact that Rawls would, and should, include parties in the overlapping consensus whose views on truth may be incoherent. Once it is seen that political liberalism allows such incoherence to reasonable parties, it is clear that the inclusion of truth and the requirement of coherence urged by Raz, Cohen, and Estlund requires more of reasonable people than is necessary for a political consensus.

In this commentary, I raise a few questions about Schmidt’s argument against (R-E): whether facts about incoherence are directly reasons for suspension on particular propositions, as opposed to reasons against sets of attitudes; whether (R-E) should really be formulated in terms of a broad category of “doxastic attitudes” that includes transitional attitudes like suspension; and whether incoherence-based reasons really must fit into the category of “epistemic reasons,” as opposed to be a more general category of right-kind reasons. Though (...) my questions reflect some skepticism about the specifics of Schmidt’s argument, I conclude that it succeeds in what I take to be its broader aim. (shrink)

In this essay I argue that the ethical and political position known as libertarianism is logically incoherent and, as such, cannot serve as a sound basis for either political theory or public policy. Given that the libertarian position is frequently used to provide the rationale for many of the economic (if not the social) policies of the right, a recognition of this incoherence is especially relevant to us today.

Contemporary theories of justice fail to recognize that the concepts constitutive of our political practices ? including ?justice? itself? have historically mutable meanings. To recognize the fact of conceptual change entails an alteration in our understanding of justice between generations. Because there can be no transhistorical theory of justice, there can be no valid theory of intergenerational justice either ? especially where the generations in question are distant ones having very different understandings of justice. The upshot is that an earlier (...) generation cannot aspire to act justly toward a later distant generation whose members? understanding of justice differs radically from theirs. Conceptual change and incommensurability render the very idea of intergenerational justice incoherent. Even so, such radical relativism need not entail moral nihilism. (shrink)

Approaches to truth and the Liar paradox seem invariably to face a dilemma: either appeal to some sort of hierarchy, or declare apparently perfectly coherent concepts incoherent. But since both options lead to severe expressive restrictions, neither seems satisfactory. The aim of this paper is a new approach, which avoids the dilemma and the resulting expressive restrictions. Previous approaches tend to appeal to some new sort of semantic value for the truth predicate to take. I argue that such approaches inevitably (...) lead to the dilemma in question. In contrast, the present proposal sticks with classical semantic values, but allows the compositional rules associated with these to admit of exceptions. I show how such an approach can be developed systematically. (shrink)
