There are three questions associated with Simpson’s Paradox (SP): (i) Why is SP paradoxical? (ii) What conditions generate SP?, and (iii) What should be done about SP? By developing a logic-based account of SP, it is argued that (i) and (ii) must be divorced from (iii). This account shows that (i) and (ii) have nothing to do with causality, which plays a role only in addressing (iii). A counterexample is also presented against the causal account. Finally, the causal and (...) logic-based approaches are compared by means of an experiment to show that SP is not basically causal. (shrink)

There are three questions associated with Simpson’s paradox (SP): (i) Why is SP paradoxical? (ii) What conditions generate SP? and (iii) How to proceed when confronted with SP? An adequate analysis of the paradox starts by distinguishing these three questions. Then, by developing a formal account of SP, and substantiating it with a counterexample to causal accounts, we argue that there are no causal factors at play in answering questions (i) and (ii). Causality enters only in connection with (...) action. (shrink)

When we compare the influences of two causes on an outcome, if the conclusion from every group is against that from the conflation, we think there is Simpson’s Paradox. The Existing Causal Inference Theory (ECIT) can make the overall conclusion consistent with the grouping conclusion by removing the confounder’s influence to eliminate the paradox. The ECIT uses relative risk difference Pd = max(0, (R − 1)/R) (R denotes the risk ratio) as the probability of causation. In contrast, Philosopher (...) Fitelson uses confirmation measure D (posterior probability minus prior probability) to measure the strength of causation. Fitelson concludes that from the perspective of Bayesian confirmation, we should directly accept the overall conclusion without considering the paradox. The author proposed a Bayesian confirmation measure b* similar to Pd before. To overcome the contradiction between the ECIT and Bayesian confirmation, the author uses the semantic information method with the minimum cross-entropy criterion to deduce causal confirmation measure Cc = (R − 1)/max(R, 1). Cc is like Pd but has normalizing property (between −1 and 1) and cause symmetry. It especially fits cases where a cause restrains an outcome, such as the COVID-19 vaccine controlling the infection. Some examples (about kidney stone treatments and COVID-19) reveal that Pd and Cc are more reasonable than D; Cc is more useful than Pd. (shrink)

We address the need for a model by considering two competing theories regarding the origin of life: (i) the Metabolism First theory, and (ii) the RNA World theory. We discuss two interrelated points, namely: (i) Models are valuable tools for understanding both the processes and intricacies of origin-of-life issues, and (ii) Insights from models also help us to evaluate the core objection to origin-of-life theories, called “the inefficiency objection”, which is commonly raised by proponents of both the Metabolism First theory (...) and the RNA World theory against each other. We use Simpson’s Paradox (SP) as a tool for challenging this objection. We will use models in various senses, ranging from taking them as representations of reality to treating them as theories/accounts that provide heuristics for probing reality. In this paper, we will frequently use models and theories interchangeably. Additionally, we investigate Conway’s Game of Life and contrast it with our SP-based approach to emergence-of-life issues. Finally, we discuss some of the consequences of our view. A scientific model is testable in three senses: (i) a logical sense, (ii) a nomological sense, and (iii) a current technological sense. The SP-based model is testable in the first two senses but it is not feasible to test it using current technology. (shrink)

In this chapter I argue that emerging soldier enhancement technologies have the potential to transform the ethical character of the relationship between combatants, in conflicts between ‘Superpower’ militaries, with the ability to deploy such technologies, and technologically disadvantaged ‘Underdog’ militaries. The reasons for this relate to Paul Kahn’s claims about the paradox of riskless warfare. When an Underdog poses no threat to a Superpower, the standard just war theoretic justifications for the Superpower’s combatants using lethal violence against their opponents (...) breaks down. Therefore, Kahn argues, combatants in that position must approach their opponents in an ethical guise relevantly similar to ‘policing’. I argue that the kind of disparities in risk and threat between opposing combatants that Kahn’s analysis posits, don’t obtain in the context of face-to-face combat, in the way they would need to in order to support his ethical conclusions about policing. But then I argue that soldier enhancement technologies have the potential to change this, in a way that reactivates the force of those conclusions. (shrink)

I describe epistemic versions of the contrast between causal and conventionally probabilistic decision theory, including an epistemic version of Newcomb's paradox.

The theory of lower previsions is designed around the principles of coherence and sure-loss avoidance, thus steers clear of all the updating anomalies highlighted in Gong and Meng's "Judicious Judgment Meets Unsettling Updating: Dilation, Sure Loss, and Simpson's Paradox" except dilation. In fact, the traditional problem with the theory of imprecise probability is that coherent inference is too complicated rather than unsettling. Progress has been made simplifying coherent inference by demoting sets of probabilities from fundamental building blocks to (...) secondary representations that are derived or discarded as needed.

Do traits evolve because they are good for the group, or do they evolve because they are good for the individual organisms that have them? The question is whether groups, rather than individual organisms, are ever “units of selection.” My exposition begins with the 1960’s, when the idea that traits evolve because they are good for the group was criticized, not just for being factually mistaken, but for embodying a kind of confused thinking that is fundamentally at odds with the (...) logic that Darwin’s theory requires. A counter-movement has arisen since the 1960’s, called multi-level selection theory, according to which selection acts at multiple levels, including the level of the group. After discussing the 1960’s attack on group selection and the concept’s subsequent revival, I examine Darwin’s views on the subject. I discuss what Darwin says about four examples: human morality, the barbed stinger of the honeybee, neuter workers in species of social insect, and the sterility of many interspecies hybrids. I argue that Darwin defended hypotheses of group selection in the first three problems, but rejected it in the fourth. I also discuss Darwin’s general views about the role of group selection in evolution. (shrink)

We shall evaluate two strategies for motivating the view that knowledge is the norm of belief. The first draws on observations concerning belief's aim and the parallels between belief and assertion. The second appeals to observations concerning Moore's Paradox. Neither of these strategies gives us good reason to accept the knowledge account. The considerations offered in support of this account motivate only the weaker account on which truth is the fundamental norm of belief.

Few debates in environmental philosophy have been more heated than the one over the nature of wilderness. And yet, when one surveys the present scene, one finds that a variety of different conceptions of wilderness are still quite popular – some more so in certain professions than others. In this paper, I look at three popular conceptions of wilderness with an eye toward sussing out the good and the bad them. I look at what I call (1) the folk view (...) of wilderness, (2) Leopold’s conception of wilderness, and (3) the legal conception of wilderness (as found in the Wilderness Act of 1964). In the final part of the paper, I sketch out a sort of spectrum account of wilderness, one that I argue allows us to capture more cases of wilderness and might serve as a useful tool in future conservation efforts.

Several recent critiques of theodicy have incorporated some form of moral objection to the theodical enterprise, in which the critic argues that one ought not to engage in the practice of theodicy. In defending theodical practice against the moral critique, Atle O. Søvik argues that the moral critique (1) begs the question against theodicy, and (2) misapprehends the implications of the claim that it is inappropriate to espouse a theodicy in certain situations. In this paper I suggest some sympathetic emendations (...) for Søvik's theodical apologetic, but I argue against Søvik's claim that the moral critique of theodicy is altogether irrelevant. (shrink)

Mill thinks our attitudes should be held in a way that’s active and ‘alive’. He believes attitudes that lack these qualities—those held dogmatically, or in unreflective conformity—are inimical to our well-being. This claim then serves as a premiss in his argument for overarching principles of liberty. He argues that attitudinal vitality, in the relevant sense, relies upon people experiencing attitudinal conflict, and that this necessitates a prioritization of personal liberties. I argue that, pace Mill, contestation isn’t required for attitudinal vitality. (...) I describe one species of attitudinal vitality that isn’t reliant upon conflict. (shrink)

Should we implement epistemically paternalistic measures outside of the narrow range of cases, like legal trials, in which their benefits and justifiability seem clear-cut? In this chapter I draw on theories of student-led pedagogy, and Jane Friedman’s work on norms of inquiry, to argue against this prospect. The key contention in the chapter is that facts about an inquirer’s interests and temperament have a bearing on whether it is better for her to, at any given moment, pursue epistemic goods via (...) outward-facing evidence-acquisition, or in a more introspective, ratiocinative fashion. This makes problems for any non-consultative approach to assisting people in inquiry, and speaks in favor of approaches which, as with student-led pedagogy, aim to ‘tap into’ the inquirer’s interests and temperament in helping them to learn.

This paper argues that justification is accessible in the sense that one has justification to believe a proposition if and only if one has higher-order justification to believe that one has justification to believe that proposition. I argue that the accessibility of justification is required for explaining what is wrong with believing Moorean conjunctions of the form, ‘p and I do not have justification to believe that p.’.

Fitch’s Paradox shows that if every truth is knowable, then every truth is known. Standard diagnoses identify the factivity/negative infallibility of the knowledge operator and Moorean contradictions as the root source of the result. This paper generalises Fitch’s result to show that such diagnoses are mistaken. In place of factivity/negative infallibility, the weaker assumption of any ‘level-bridging principle’ suffices. A consequence is that the result holds for some logics in which the “Moorean contradiction” commonly thought to underlie the result (...) is in fact consistent. This generalised result improves on the current understanding of Fitch’s result and widens the range of modalities of philosophical interest to which the result might be fruitfully applied. Along the way, we also consider a semantic explanation for Fitch’s result which answers a challenge raised by Kvanvig. (shrink)

In recent years there has been a revitalised interest in non-classical solutions to the semantic paradoxes. In this paper I show that a number of logics are susceptible to a strengthened version of Curry's paradox. This can be adapted to provide a proof theoretic analysis of the omega-inconsistency in Lukasiewicz's continuum valued logic, allowing us to better evaluate which logics are suitable for a naïve truth theory. On this basis I identify two natural subsystems of Lukasiewicz logic which individually, (...) but not jointly, lack the problematic feature. (shrink)

Permissivism says that for some propositions and bodies of evidence, there is more than one rationally permissible doxastic attitude that can be taken towards that proposition given the evidence. Some critics of this view argue that it condones, as rationally acceptable, sets of attitudes that manifest an untenable kind of arbitrariness. I begin by providing a new and more detailed explication of what this alleged arbitrariness consists in. I then explain why Miriam Schoenfield’s prima facie promising attempt to answer the (...) Arbitrariness Objection, by appealing to the role of epistemic standards in rational belief formation, fails to resolve the problem. Schoenfield’s strategy is, however, a useful one, and I go on to explain how an alternative form of the standards-based approach to Permissivism – one that emphasizes the significance of the relationship between people’s cognitive abilities and the epistemic standards that they employ – can respond to the arbitrariness objection.

The Russell's paradox concerns the foundations of naive set theory. This short short paper is about how it can be interpreted in other contexts and has significance in the world of commands. Understanding the paper assumes that the reader is broadly familiar with the foundations of set theory and its history. The text contains many formulas and therefore the reader should be comfortable in the world of logical formulas. My example is somewhat similar to the barber paradox. There, (...) too, we are puzzled by the feasibility of a task. In the case of the barber paradox there is a solution: the barber is a woman, in my example there is no such escape. (shrink)

The standard view of academic freedom and free speech is that they play complementary roles in universities. Academic freedom protects academic discourse, while other public discourse in universities is protected by free speech. Here I challenge this view, broadly, on the grounds that free speech in universities sometimes undermines academic practices. One defense of the standard view, in the face of this worry, says that campus free speech actually furthers the university’s academic aims. Another says that universities have a secondary (...) democratic function, which cannot be fulfilled without free speech on campus. I identify shortcomings in both types of arguments. (shrink)

I argue that Meno’s Paradox targets the type of knowledge that Socrates has been looking for earlier in the dialogue: knowledge grounded in explanatory definitions. Socrates places strict requirements on definitions and thinks we need these definitions to acquire knowledge. Meno’s challenge uses Socrates’ constraints to argue that we can neither propose definitions nor recognize them. To understand Socrates’ response to the challenge, we need to view Meno’s challenge and Socrates’ response as part of a larger disagreement about the (...) value of inquiry. (shrink)

Moral expressivists think that moral thoughts and sentences don’t represent or describe the world, at least not in any interesting sense. Global expressivists think that _no_ thoughts or sentences represent the world; local expressivists think that some do and others don’t. Huw Price has influentially argued that local expressivism collapses into global expressivism, due both to the effects of minimalist theories of representation and similar concepts, and to an unappreciated consequence of the success of specific expressivist theories like moral expressivism. (...) In this paper I argue that Price’s arguments don’t succeed. While they can be fixed, doing so makes them miss their intended target. Local expressivists should therefore not be worried by Price’s arguments. (shrink)

Moore’s Paradox is a test case for any formal theory of belief. In Knowledge and Belief, Hintikka developed a multimodal logic for statements that express sentences containing the epistemic notions of knowledge and belief. His account purports to offer an explanation of the paradox. In this paper I argue that Hintikka’s interpretation of one of the doxastic operators is philosophically problematic and leads to an unnecessarily strong logical system. I offer a weaker alternative that captures in a more (...) accurate way our logical intuitions about the notion of belief without sacrificing the possibility of providing an explanation for problematic cases such as Moore’s Paradox. (shrink)

This paper examines two recent contributions to the hate speech literature – by Steven Heyman and Jeremy Waldron – which seek a justification for the legal restriction of hate speech in an account of the way that hate speech infringes against people’s dignity. These analyses look beyond the first-order hurts and disadvantages suffered by the immediate targets of hate speech, and consider the prospect of hate speech sustaining complex social structures whose wide-scale operations lower the social status of members of (...) targeted groups. In Heyman’s and Waldron’s accounts we find plausible insights into the nature of identity-based social hierarchies, and the harms that redound to subordinated people under the operations of such hierarchies. I argue, however, that both analyses are unsuccessful as justifications for the restriction of hate speech, because they do not ultimately provide reason to think that hate speech is responsible for creating or sustaining identity-based social hierarchies. (shrink)

In disagreements about trivial matters, it often seems appropriate for disputing parties to adopt a ‘middle ground’ view about the disputed matter. But in disputes about more substantial controversies (e.g. in ethics, religion, or politics) this sort of doxastic conduct can seem viciously acquiescent. How should we distinguish between the two kinds of cases, and thereby account for our divergent intuitions about how we ought to respond to them? One possibility is to say that ceding ground in a trivial dispute (...) is appropriate because the disputing parties are usually epistemic peers within the relevant domain, whereas in a more substantial disagreement the disputing parties rarely, if ever, qualify as epistemic peers, and so ‘sticking to one’s guns’ is usually the appropriate doxastic response. My aim in this paper is to explain why this way of drawing the desired distinction is ultimately problematic, even if it seems promising at first blush. (shrink)

In recent work Mary Kate McGowan presents an account of oppressive speech inspired by David Lewis's analysis of conversational kinematics. Speech can effect identity-based oppression, she argues, by altering 'the conversational score', which is to say, roughly, that it can introduce presuppositions and expectations into a conversation, and thus determine what sort of subsequent conversational 'moves' are apt, correct, felicitous, etc., in a manner that oppresses members of a certain group (e.g. because the suppositions and expectations derogate or demean members (...) of that group). In keeping with the Lewisian picture, McGowan stresses the asymmetric pliability of conversational scores. She argues that it is easier to introduce (for example) sexist presuppositions and expectations into a conversation than it is to remove them. Responding to a sexist remark, she thus suggests, is like trying to "unring a bell". I begin by situating McGowan's work in the wider literature on speech and social hierarchy, and explaining how her account of oppressive speech improves upon the work of others in its explication of the relationship between individuals' verbal conduct and structurally oppressive social arrangements. I then propose an explanation and supportive elaboration of McGowan's claims about the asymmetric pliability of conversations involving identity-oppressive speech. Rather than regarding such asymmetry as a sui generis phenomenon, I show how we can understand it as a consequence of a more general asymmetry between making things salient and un-salient in speech, and I show how this asymmetry also operates in various cases that interested Lewis.

Since it was presented in 1963, Chisholm’s paradox has attracted constant attention in the deontic logic literature, but without the emergence of any definitive solution. We claim this is due to its having no single solution. The paradox actually presents many challenges to the formalization of deontic statements, including (1) context sensitivity of unconditional oughts, (2) formalizing conditional oughts, and (3) distinguishing generic from nongeneric oughts. Using the practical interpretation of ‘ought’ as a guideline, we propose a linguistically (...) motivated logical solution to each of these problems, and explain the relation of the solution to the problem of contrary-to-duty obligations.

If I were to say, “Agnes does not know that it is raining, but it is,” this seems like a perfectly coherent way of describing Agnes’s epistemic position. If I were to add, “And I don’t know if it is, either,” this seems quite strange. In this chapter, we shall look at some statements that seem, in some sense, contradictory, even though it seems that these statements can express propositions that are contingently true or false. Moore thought it was paradoxical (...) that statements that can express true propositions or contingently false propositions should nevertheless seem absurd like this. If we can account for the absurdity, we shall solve Moore’s Paradox. In this chapter, we shall look at Moore’s proposals and more recent discussions of Moorean absurd thought and speech. (shrink)

Chilling Effects occur when the risks surrounding a speech restriction inadvertently deter speech that lies outside the restriction’s official scope. Contrary to the standard interpretation of this phenomenon I show how speech deterrence for individuals can sometimes, instead of suppressing discourse at the group level, intensify it – with results that are still unwelcome, but crucially unlike a ‘chill’. Inadvertent deterrence of speech may, counterintuitively, create a Heating Effect. This proposal gives us a promising explanation of the intensity of public (...) debate on topics for which there is, simultaneously, evidence of people self-censoring, for fear of breaching speech restrictions. It also helps to pinpoint two problems with existing theoretical analyses of the Chilling Effect: (i) in how they construe the relation between individual- and group-level discursive phenomena; and (ii) how they characterize the distinctively wrongful nature of inadvertent speech deterrence.

According to the “paradox of knowability”, the moderate thesis that all truths are knowable – ... – implies the seemingly preposterous claim that all truths are actually known – ... –, i.e. that we are omniscient. If Fitch’s argument were successful, it would amount to a knockdown rebuttal of anti-realism by reductio. In the paper I defend the nowadays rather neglected strategy of intuitionistic revisionism. Employing only intuitionistically acceptable rules of inference, the conclusion of the argument is, firstly, not (...) ..., but .... Secondly, even if there were an intuitionistically acceptable proof of ..., i.e. an argument based on a different set of premises, the conclusion would have to be interpreted in accordance with Heyting semantics, and read in this way, the apparently preposterous conclusion would be true on conceptual grounds and acceptable even from a realist point of view. Fitch’s argument, understood as an immanent critique of verificationism, fails because in a debate dealing with the justification of deduction there can be no interpreted formal language on which realists and anti-realists could agree. Thus, the underlying problem is that a satisfactory solution to the “problem of shared content” is not available. I conclude with some remarks on the proposals by J. Salerno and N. Tennant to reconstruct certain arguments in the debate on anti-realism by establishing aporias. (shrink)

I give an interpretation according to which Meno’s paradox is an epistemic regress problem. The paradox is an argument for skepticism assuming that (1) acquired knowledge about an object X requires prior knowledge about what X is and (2) any knowledge must be acquired. (1) is a principle about having reasons for knowledge and about the epistemic priority of knowledge about what X is. (1) and (2) jointly imply a regress-generating principle which implies that knowledge always requires an (...) infinite sequence of known reasons. Plato’s response to the problem is to accept (1) but reject (2): some knowledge is innate. He argues from this to the conclusion that the soul is immortal. This argument can be understood as a response to an Eleatic problem about the possibility of coming into being that turns on a regress-generating causal principle analogous to the regress-generating principle presupposed by Meno’s paradox. (shrink)

In this paper I argue that Donald Davidson's rejection of the notion of language, as commonly understood in philosophy and linguistics, is justified. However, I argue that his position needs to be supplemented by an account of the development and nurture of pre-linguistic communicative skills. Davidson argues (in ‘A Nice Derangement of Epitaphs' and elsewhere) that knowledge of a language (conceived of as a set of rules or conventions) is neither sufficient nor necessary for 'linguistic' communication. The strongest argument against (...) the initial formulation is that while Davidson may have shown that knowledge of a language is not sufficient, he failed to show that it is not necessary. Subsequently, Davidson has invoked his Triangulation' thesis, to show that understanding can rest on the apprehension of mutuality in a shared objective world, and does not presuppose the sharing of rules or practices. I argue that the starting position arrived at from the triangulation thesis itself presupposes the possibility of communication. The triangulation thesis needs, therefore, to be supplemented by a (non-reductive) naturalistic account of non-linguistic communicative skills. In such an account we must posit shared practices (practices of mutual engagement with a shared world), but not an account of practices conceived on the model of rules or conventions. I note, finally, that by adopting such an approach we offer a way of explicating the formulation of passing theories, which in Davidson's account are the point at which communicative understanding occurs.

Some authors claim that hate speech plays a key role in perpetuating unjust social hierarchy. One prima facie plausible hypothesis about how this occurs is that hate speech has a pernicious influence on the attitudes of children. Here I argue that this hypothesis has an important part to play in the formulation of an especially robust case for general legal prohibitions on hate speech. If our account of the mechanism via which hate speech effects its harms is built around claims (...) about hate speech’s influence on children, then we will be better placed to acquire evidence that demonstrates the processes posited in our account, and better placed to ascribe responsibility for these harms to individuals who engage in hate speech. I briefly suggest some policy implications that come with developing an account of the harm of hate speech along these lines. (shrink)

The idea that human beings are intellectually self-governing plays two roles in free-speech theory. First, this idea is frequently called upon as part of the justification for free speech. Second, it plays a role in guiding the translation of free-speech principles into legal policy by underwriting the ascriptive framework through which responsibility for certain kinds of speech harms can be ascribed. After mapping out these relations, I ask what becomes of them once we acknowledge certain very general and profound limitations (...) in people's capacity for intellectual self-governance. I argue that acknowledging these limitations drastically undermines the putative justifications for free speech of the type that I identify in the first part of the paper. I then show how we can reformulate an account of intellectual and doxastic responsibility on which we may still be held responsible for what we think or believe even though we lack agent-causal capacities in our thinking and believing. Then, in light of this ascriptive account of intellectual responsibility, I show how the key ideahave minds of their owncan (and should) still play a significant role in guiding the legislative outworkings of free speech. (shrink)

An important suggestion of objective Bayesians is that the maximum entropy principle can replace a principle which is known to get into paradoxical difficulties: the principle of indifference. No one has previously determined whether the maximum entropy principle is better able to solve Bertrand’s chord paradox than the principle of indifference. In this paper I show that it is not. Additionally, the course of the analysis brings to light a new paradox, a revenge paradox of the chords, (...) that is unique to the maximum entropy principle. (shrink)

Contemporary proponents of theodicy generally believe that a theodical reply to the evidential argument from evil must involve some appeal to the afterlife. In Richard Swinburne's writings on theodicy, however, we find two arguments that may be offered in opposition to this prevailing view. In this paper, these two arguments - the argument from usefulness and the argument from assumed consent - are explained and evaluated. It is suggested that both of these arguments are rendered ineffective by their failure to (...) distinguish between the different ways in which persons may be of-use in the attainment of some good state of affairs.

The sentences ‘p but I don’t believe p’ (omissive form) and ‘p but I believe that not-p’ (comissive form) are typical examples of Moore’s paradox. When an agent (sincerely) asserts such sentences under normal circumstances, we consider his statements absurd. The Simple Solution (Moore, Heal, Wolgast, Kriegel, et al.) finds the source of absurdity for such statements in a certain formal contradiction (some kind of like ‘p & not-p’), the presence of which is lexically disguised. This solution is facing (...) criticism since it is obvious that the denial of the contradiction allegedly hidden in Moore’s paradox will not become an expression of tautology for us. Hintikka offers another solution to Moore’s paradox. In his view, the source of absurdity is the practical inconceivability of the situation, in which the agent would be able to hold mutually incompatible (inconsistent) beliefs. The sentences ‘p but I don’t believe that p’ and ‘p but I believe that not-p’ sound absurd because they express high-ordered beliefs that no rational agent can hold. A belief expressed in the sentence ‘he believes that p’, in order to be available to the agent, must be compatible with the truth of everything the agent believes. The problem with Hintikka’s solution is that it relies on an epistemic principle that does not correspond to our general intuitions about the notion of belief. According to this principle, there must be a close connection between the sentence ‘p but I don’t believe that p’ and the sentence ‘I believe that is the case is that p but I don’t believe that p’. However, it is not difficult to imagine the context for situations when the agent asserts the sentence ‘p but I don’t believe that p’ when s/he believes that p, but in parallel does not hold any high-ordered belief about his/her belief in p. For example, the agent does not recognize oneself in a photograph after a hard plastic surgery, and when one asks him ‘who is this?’ it would not be absurd for him/her to accept the following description of his/her beliefs ‘I believe that {I am me} but I don’t believe that I believe that {I am me}’. Wittgenstein provides an alternative solution based on a descriptive analysis of the grammar of verbs we use to express, attribute, and understand each other’s psychological states. In his view, the everyday practice of using the verb ‘believe’ demonstrates a characteristic asymmetry in the semantic and logical properties of the usage of this verb in the first person. The expression ‘I believe falsely’ has no real meaning since no one can meaningfully say the sentence ‘Now I believe falsely that p’ on their own behalf. Therefore, the genuine source of absurdity is associated with situations of self-attribution of false belief by the agent. Despite its originality, Wittgenstein’s solution faces objections. For example, in a certain context, it would not be absurd to assert the sentence ‘There are no beliefs, but I don’t believe in it’, unlike the sentence ‘There are no beliefs and I believe that it is so’. The solution proposed by Wittgenstein does not allow us to correct the situation since one could assert quite reasonably and without any absurdity a sentence like ‘In fact, there are no beliefs and now I falsely believe that it is so’. Based on Evans’ principle of epistemic transparency, some researchers (Atlas, Chan, Kwon, et al.) offer another strategy for solving Moore’s paradox, in which peculiar attention is paid to the dependence of understanding and evaluating the meaning of the sentences ‘p but I do not believe that p’ and ‘p but I believe that not-p’ from the immediate context of their usage. The source of absurdity should be looked for in the established practice of the self-referential use of the pronoun ‘I’. In the researchers’ view, Moore’s paradox arises only in the context of situations where the agent asserting such sentences is conscious speaking about oneself. Therefore, there is an obvious structural analogy between the sentences of the Liar family (‘This very sentence is false’, ‘Now I am lying’, etc.) and Moore’s paradox (‘p but I don’t believe that p’, ‘p but I believe that not-p’) – self-reference is constitutive for both families of paradoxical statements.

Gail Murrow and Richard Murrow offer a novel account of dehumanization, by synthesizing data which suggest that where subject S has a dehumanized view of group G, S‘s neural mechanisms of empathy show a dampened response to the suffering of members of G, and S‘s judgments about the humanity of members of G are largely non-conscious. Here I examine Murrow and Murrow‘s suggestions about how identity-based hate speech bears responsibility for dehumanization in the first place. I identify a distinction between (...) (i) accounts of the nature of the harm effected by identity prejudice, and (ii) accounts of how hate speech contributes to the harms of identity prejudice. I then explain why Murrow and Murrow‘s proposal is more aptly construed as an account of type (i), and explain why accounts of this type, even if they‘re plausible and evidentially well-supported, have limited implications in relation to justifications for anti-hate speech law.

Shills are people who endorse products and companies for pay, while pretending that their endorsements are ingenuous. Here we argue that there is something objectionable about shilling that is not reducible to its bad consequences, the lack of epistemic conscientiousness it often relies upon, or to the shill’s insincerity. Indeed, we take it as a premise of our inquiry that shilling can sometimes be sincere, and that its wrongfulness is not mitigated by the shill’s sincerity, in cases where the shill (...) is sincere. Our proposal is that the shill’s defining characteristic is their knowingly engaging in a kind of speech that obscures a certain aspect of its social status – most commonly, by pretending to speak on their own personal behalf, while in fact speaking as an employee – and that this sort of behaviour is objectionable irrespective of any other features of the shill’s conduct. This sort of obfuscation undermines a socially beneficial communicative custom, in which we conscientiously mark the distinction between personal speech and speech-for-hire. (shrink)

Joel Feinberg’s Offense to Others is the most comprehensive contemporary work on the significance of offense in a liberal legal system. Feinberg argues that being offended can impair a person’s liberty, much like a nuisance, and that it is therefore legitimate in principle to regulate conduct because of its offensiveness. In this article, I discuss some overlooked considerations that give us reason to resist Feinberg’s conclusion, even while granting this premise. My key claim is that the regulation of offense can (...) inadvertently increase the incidence of offense, by nurturing offense-taking sensibilities. In the course of defending this claim and spelling out its implications, I explain why concerns about the inadvertent nurturing of offense are now more pressing, given the identity–political character of contemporary offense-based social conflicts, and I discuss why a reluctance to legally regulate offensive conduct need not be insensitive to the identity–political issues that animate those conflicts.

Austin's distinction between locutionary and illocutionary acts has offered a fruitful way of focussing the relation between language and communication. In particular, by adopting the distinction we attend to linguistic and communicative subjects as actors, not just processors or conduits of information. Yet in many attempts to explicate the constitution of illocutionary acts the subject as actor is subsumed within the role of linguistic rules or conventions. I propose an account of illocutionary acts in which rules or conventions are secondary (...) to what I call communicative skills. These skills are taken as the primary component of communicative competence. They are derived from the principle that linguistic communication is not ultimately a linguistic matter, but relates instead to the way a communicator uses language. This principle is found in the work of Donald Davidson, but Davidson has tended to concentrate on semantics, and leaves the details of linguistic communication for pragmatics.

In this paper, I argue that the recent discussion on the time - reversal invariance of classical electrodynamics (see (Albert 2000: ch.1), (Arntzenius 2004), (Earman 2002), (Malament 2004),(Horwich 1987: ch.3)) can be best understood assuming that the disagreement among the various authors is actually a disagreement about the metaphysics of classical electrodynamics. If so, the controversy will not be resolved until we have established which alternative is the most natural. It turns out that we have a paradox, namely that (...) the following three claims are incompatible: the electromagnetic fields are real, classical electrodynamics is time-reversal invariant, and the content of the state of affairs of the world does not depend on whether it belongs to a forward or a backward sequence of states of the world.

Expressivists explain the expression relation which obtains between sincere moral assertion and the conative or affective attitude thereby expressed by appeal to the relation which obtains between sincere assertion and belief. In fact, they often explicitly take the relation between moral assertion and their favored conative or affective attitude to be exactly the same as the relation between assertion and the belief thereby expressed. If this is correct, then we can use the identity of the expression relation in the two (...) cases to test the expressivist account as a descriptive or hermeneutic account of moral discourse. I formulate one such test, drawing on a standard explanation of Moore's paradox. I show that if expressivism is correct as a descriptive account of moral discourse, then we should expect versions of Moore's paradox where we explicitly deny that we possess certain affective or conative attitudes. I then argue that the constructions that mirror Moore's paradox are not incoherent. It follows that expressivism is either incorrect as a hermeneutic account of moral discourse or that the expression relation which holds between sincere moral assertion and affective or conative attitudes is not identical to the relation which holds between sincere non-moral assertion and belief. A number of objections are canvassed and rejected. (shrink)

If we want to say that all truths are knowable Fitch’s Paradox leads us to conclude that all truths are known. Is it a real philosophical problem or a mere modeling problem? Is it possible to express the idea of knowability using modal logic? The Knowability Principle is expressed by the formula: if Phi is true then it is possible to know that Phi. But what is the meaning of possibility in this context? Using standard modal operators under what (...) condition can we express the idea of knowability? We will in particular examine the subjacent relations of the modal operators in a Kripke Model. We will define the possibility as the possibility of learning opposed to an unclear possibility. Then we will show that Fitch’s Paradox becomes clearer and we will examine how the Knowability Principle could be expressed in such frame. (shrink)

The principle of indifference is supposed to suffice for the rational assignation of probabilities to possibilities. Bertrand advances a probability problem, now known as his paradox, to which the principle is supposed to apply; yet, just because the problem is ill‐posed in a technical sense, applying it leads to a contradiction. Examining an ambiguity in the notion of an ill‐posed problem shows that there are precisely two strategies for resolving the paradox: the distinction strategy and the well‐posing strategy. (...) The main contenders for resolving the paradox, Marinoff and Jaynes, offer solutions which exemplify these two strategies. I show that Marinoff’s attempt at the distinction strategy fails, and I offer a general refutation of this strategy. The situation for the well‐posing strategy is more complex. Careful formulation of the paradox within measure theory shows that one of Bertrand’s original three options can be ruled out but also shows that piecemeal attempts at the well‐posing strategy will not succeed. What is required is an appeal to general principle. I show that Jaynes’s use of such a principle, the symmetry requirement, fails to resolve the paradox; that a notion of metaindifference also fails; and that, while the well‐posing strategy may not be conclusively refutable, there is no reason to think that it can succeed. So the current situation is this. The failure of Marinoff’s and Jaynes’s solutions means that the paradox remains unresolved, and of the only two strategies for resolution, one is refuted and we have no reason to think the other will succeed. Consequently, Bertrand’s paradox continues to stand in refutation of the principle of indifference. (shrink)

This is a review of a long, comprehensive, and mostly very good collection of philosophical essays on human rights. I briefly summarise the main ideas put forward in some of the essays that I most admired in the collection. While the collection includes essays from proponents of a wide range of theoretical and methodological perspectives, I suggest in my review that the collection's overall function is to serve as a kind of demonstrative rejoinder to those philosophers, like Raz, who argue (...) that we can and should theorise human rights without trying to furnish them with philosophical foundations.

This piece is a side-by-side review of two books: Strangers Drowning, by Larissa MacFarquhar, and Doing Good Better, by William MacAskill. Both books are concerned with the question of whether we should try to live as morally good a life as possible. MacAskill thinks the answer is 'yes', and his book is an overview of how the Effective Altruist movement approaches the problem of how to achieve a morally optimal life. MacFarquhar's book is a more descriptive account of the lives (...) of people who aim to live in a morally optimal way. Her discussion is nuanced, and somewhat ambivalent about the merits of this aim. My review brings out some commonalities and differences between the two books, and critically digests the arguments on offer. (shrink)

I argue that Donald Davidson's rejection of the notion of language, as commonly understood in philosophy and linguistics, is justified. However, I argue that his position needs to be supplemented by an account of the development and nurture of pre-linguistic communicative skills. Davidson argues (in 'A Nice Derangement of Epitaphs' and elsewhere) that knowledge of a language (conceived of as a set of rules or conventions) is neither sufficient nor necessary for 'linguistic' communication. The strongest argument against the initial formulation (...) is that while Davidson may have shown that knowledge of a language is not sufficient, he failed to show that it is not necessary. Subsequently, Davidson has invoked his 'triangulation' thesis, to show that understanding can rest on the apprehension of mutuality in a shared objective world, and does not presuppose the sharing of rules or practices. I argue that the starting position arrived at from the triangulation thesis itself presupposes the possibility of communication. The triangulation thesis needs, therefore, to be supplemented by a (non-reductive) naturalistic account of non-linguistic communicative skills. In such an account we must posit shared practices (practices of mutual engagement with a shared world), but not an account of practices conceived on the model of rules or conventions. I note, finally, that by adopting such an approach we offer a way of explicating the formulation of passing theories, which in Davidson's account are the point at which communicative understanding occurs.

The question of whether lies by those who govern are acceptable receives a clear focus and an ideal case in the Republic. Against C. D. C. Reeve, and T. C. Brickhouse and N. D Smith, I argue that the Republic’s apparent recommendation of administrative lies is incoherent. While lies may be a necessary part of the City’s administration, the process and practice of lying undermines that nature which is necessary for any suitable ruler – rendering the ideal impossible. I argue (...) that this analysis, while concerned with an ideal case, also applies to the political realist’s regrettable-but-necessary defence of such practices. (shrink)

Wittgenstein constantly invokes teaching, training and learning in his later work. It is therefore interesting to consider what role these notions play for him there. I argue that their use is central to Wittgenstein’s attempt to refute cognitivist assumptions, and to show how normative practices can be understood without the threat of circularity, grounded not in a kind of seeing, but in doing, and the natural reactions of an organism. This can generate a worry that Wittgenstein’s position is quietist and (...) anti-critical: critique, as a challenge to the taken-for-granted grammar of our language game, is technically meaningless. I argue that Wittgenstein does not rule out critique. His own practice demonstrates that critique is possible, but takes place within a language game, and its status as critique is always subject to challenge in the agora of a discourse. (shrink)

Zeno’s paradoxes of motion, allegedly denying motion, have been conceived to reinforce the Parmenidean vision of an immutable world. The aim of this article is to demonstrate that these famous logical paradoxes should be seen instead as paradoxes of immobility. From this new point of view, motion is therefore no longer logically problematic, while immobility is. This is convenient since it is easy to conceive that immobility can actually conceal motion, and thus the proposition “immobility is mere illusion of the (...) senses” is much more credible than the reverse thesis supported by Parmenides. Moreover, this proposition is also supported by modern depiction of material bodies: the existence of a ceaseless random motion of atoms—the ‘thermal agitation’—in the scope of contemporary atomic theory, can offer a rational explanation of this ‘illusion of immobility’. Our new approach to Zeno’s paradoxes therefore leads to presenting the novel concept of ‘impermobility’, which we think is a more adequate description of physical reality. (shrink)
