Longtermists have recently argued that it is overwhelmingly important to do what we can to mitigate existential risks to humanity. I consider three mistakes that are often made in calculating the value of existential risk mitigation. I show how correcting these mistakes pushes the value of existential risk mitigation substantially below leading estimates, potentially low enough to threaten the normative case for existential risk mitigation. I use this discussion to draw four positive lessons for the study of existential risk. -/- (...) . (shrink)

Ever since the publication of Kripke’s Wittgenstein on Rules and Private Language, there’s been a raging debate in philosophy of language over whether meaning and thought are, in some sense, normative. Most participants in the normativity wars seem to agree that some uses of meaningful expressions are semantically correct while disagreeing over whether this entails anything normative. But what is it to say that a use of an expression is semantically correct? On the so-called orthodox construal, it is to say (...) that it doesn’t result in a factual mistake, that is, in saying or thinking something false. On an alternative construal it is instead to say that it doesn’t result in a distinctively linguistic mistake, that is, in misusing the expression. It is natural to think that these two construals of semantic correctness are simply about different things and not in competition with each other. However, this is not the common view. Instead, several philosophers who subscribe to the orthodox construal have argued that the alternative construal of correctness as use in accordance with meaning doesn’t make any sense, partly because there are no clear cases of linguistic mistakes (Whiting 2016, Wikforss 2001). In this paper I develop and defend the idea that there’s a distinctively linguistic notion of correctness as use in accordance with meaning and argue that there are clear cases of linguistic mistakes.

This paper examines two mistakes regarding David Lewis’ Principal Principle that have appeared in the recent literature. These particular mistakes are worth looking at for several reasons: The thoughts that lead to these mistakes are natural ones, the principles that result from these mistakes are untenable, and these mistakes have led to significant misconceptions regarding the role of admissibility and time. After correcting these mistakes, the paper discusses the correct roles of time and admissibility. With these results in hand, the (...) paper concludes by showing that one way of formulating the chance–credence relation has a distinct advantage over its rivals. (shrink)

In this ground-breaking article submitted for publication in mid-1986, Lucinda Vandervort creates a radically new and comprehensive theory of sexual consent as the unequivocal affirmative communication of voluntary agreement. She argues that consent is a social act of communication with normative effects. To consent is to waive a personal legal right to bodily integrity and relieve another person of a correlative legal duty. If the criminal law is to protect the individual’s right of sexual self-determination and physical autonomy, rather than (...) simply to regulate the type and degree of force that may be used to obtain compliance from a victim, the point of reference must be the individual complainant, as a person who makes choices, not social norms or objective tests based on the ordinary person. To determine whether consent is voluntary, attention must be directed to the presence or absence of factors that had a coercive impact on the individual complainant, a specific person with a collection of social, cultural, and psychological experiences, needs, fears, values, and priorities. Individuals have the right to exercise self-determination in accordance with their own values and perceptions, not those of a mythical victim. Accordingly, Vandervort argues that the prosecution may show either refusal, the absence of affirmative voluntary agreement (including passivity or the absence of consent due to unconsciousness), or circumstances that invalidate any apparent consent. Any of these prove the absence of consent for the purposes of establishing the actus reus of sexual assault. -/- The definition of consent as the affirmative communication of voluntary agreement is also shown to have a variety of implications for the interpretation and application of the law of sexual assault and the handling of evidentiary issues at trial in sexual assault cases. Key among these is the pivotal significance of the legal definition of consent as a tool to bar availability of the defence of “mistaken belief in consent.” Vandervort argues that in many cases the defence of “mistaken belief in consent” is based on ignorance of the law of consent, mistake about the legal definition of consent, or a failure to appreciate the legal significance of facts that are well-known, and not on a mistaken belief in an erroneous set of facts. The broad proposition asserted here is that a statutory criminal law is enforceable only if all defences based directly or indirectly on belief in the validity of extra-legal norms that authorize infringement of rights protected by the criminal law are barred. This proposition and the characterization of some mistakes about consent as legal, not factual, are also shown to be useful to exclude rape-myths and stereotypical assumptions---the stuff of which “social” definitions of consent have long been constructed---from the decision-making process at trial. -/- .

We present the details of a methodology for quality assurance in large medical terminologies and describe three algorithms that can help terminology developers and users to identify potential mistakes. The methodology is based in part on linguistic criteria and in part on logical and ontological principles governing sound classifications. We conclude by outlining the results of applying the methodology in the form of a taxonomy different types of errors and potential errors detected in SNOMED-CT.

A suggestion famously made by Peter Winch and carried through to present discussions holds that what constitutes the social as a kind consists of something shared – rules or practices commonly learned, internalized, or otherwise acquired by all members belonging to a society. This essays argues against the explanatory efficacy of appeals to this shared something as constitutive of a social kind by examining a violation of social norms or rules, viz., mistakes. I argue that an asymmetric relation exists between (...) the notion of mistakes and that of the social. In particular, mistakes do not presuppose a concept of the social, but the concept of the social requires prior specification of a category of mistakes. But no such prior specification proves possible. The very notion of a mistake is so inchoate that it makes it impossible to provide the kind of regimentation required for a rule-governed domain. Thus, there may be recognized mistakes even in the absence of a unified system or common knowledge of norms.Later writers attempt to avoid Winch's over-strong assumption that something shared and internal constitutes the social but cannot. Extending recent work by Stephen Turner, I argue that ``the social'' is not a domain that is susceptible to lawlike treatment, but rather a heterogeneous, motley collection. For absent the assumption of a shared something, no social object exists to be explained. So, I conclude, we have at present no clear way of marking out the social as a coherent or unified domain of inquiry. (shrink)

What are the justifications for and constraints on the use of force in self-defense? In his book The Morality of Defensive Force, Jonathan Quong presents the moral status account to address this and other fundamental questions. According to the moral status account, moral liability to defensive harm is triggered by treating others with less respect than they are due. At the same time, Quong rejects the relevance of culpability to the morality of defensive harming. In this article I argue that (...) this rejection of culpability is unfounded and that Quong fails to establish his account as superior to the culpability account of liability to defensive harm.

Attribution theorists assume that character information informs judgments of blame. But there is disagreement over why. One camp holds that character information is a fundamental determinant of blame. Another camp holds that character information merely provides evidence about the mental states and processes that determine responsibility. We argue for a two-channel view, where character simultaneously has fundamental and evidential effects on blame. In two large factorial studies (n = 495), participants rate whether someone is blameworthy when he makes a (...) class='Hi'>mistake (burns a cake or misses a bus stop). Although mental state inferences predict blame judgments, character information does not. Using mediation analyses, we find that character information influences responsibility via two channels (Studies 3–4; n = 447), which are sensitive to different kinds of information (Study 5; n = 149). On the one hand, forgetfulness increases judgments of responsibility, because mental lapses manifest an objectionable character flaw. On the other hand, forgetfulness decreases judgments of state control, which in turn decreases responsibility judgments. These two channels cancel out, which is why we find no aggregate effect of forgetfulness on responsibility. Our results challenge several fundamental assumptions about the role of character information in moral judgment, including that good character typically mitigates blame. (shrink)

In this chapter, we consider the plausibility and consequences of the use of the term “honest errors” to describe the accidental killings of civilians resulting from the US military’s drone campaigns in Iraq, Syria, Afghanistan, and elsewhere. We argue that the narrative of “honest errors” unjustifiably excuses those involved in these killings from moral culpability, and reinforces long-standing, pernicious assumptions about the moral superiority of the US military and the inevitability of civilian deaths in combat. Furthermore, we maintain that, given (...) the knowledge-distorting practices within the US military’s organizational structure, few if any civilian deaths from drone strikes meet the criteria of a genuinely morally excusing “honest mistake”. Instead, these accidental killings often reflect objectionable attitudes of relative disregard for the safety of civilians. These attitudes are, we argue, sufficient to warrant the attribution of blame and moral responsibility, both with respect to certain individual actions and with respect to the US military as an institution. In light of this, we propose incorporating a Principle of the Moral Equality of Non-combatants into military assessments of what counts as “acceptable risk” to civilians. This would go some way, we argue, to redressing the ongoing injustice inflicted on the victims of civilian killings by the failure of the US military and US political leadership to take moral responsibility for unjustified civilian deaths.

This is a draft of my chapter on Agency and Mistakes for the Routledge Handbook of Philosophy of Agency. In it, I focus on performance mistakes and distinguish them from other "derivative" mistakes that we make as agents. I argue that a proper understanding of these mistakes recommends a generalized fallibilism about human agency.

In ‘Excusing Mistakes of Law’, Gideon Yaffe sets out to ‘vindicate’ the claim ‘that mistakes of law never excuse’ by ‘identifying the truth that is groped for but not grasped by those who assert that ignorance of law is no excuse’. Yaffe does not offer a defence of the claim that mistakes of law never excuse. That claim, Yaffe argues, is false. Yaffe’s article is, rather, an effort to assess what plausible thought might be behind the idea that mistakes of (...) law often should not excuse. (Yaffe is interested in more than just the descriptive claim that in Anglo-American legal jurisdictions mistakes of law routinely do not, in fact, excuse.) More particularly, Yaffe is interested in what plausible normative justification there might be for this asymmetric pattern: -/- Asymmetry: False beliefs about non-legal facts often excuse, but false beliefs about the law rarely excuse. -/- Yaffe offers a complex argument in support of Asymmetry. This paper is organised around my reconstruction of Yaffe’s argument. I argue that Yaffe’s argument does not succeed, but that his argument provides a template for an argument that could succeed.

John Hick’s theory concerning plurality of religions is an ontologic pluralism according to which all religions are authentic ways for man to attain the "real an sich". Gods of religions are real as perceived and veridical hallucinations; while the “real an sich” has ineffable substantial and trans-categorical properties. Hick’s view suffers from several problems. As a second order analysis of religions, Hick’s view is not a correct one. To reject naturalism, it falls into an epistemological circle, where distinction between formal (...) and substantial properties fades away. It seems that Hick is captured by a category mistake in the presentation of his own theory concerning authenticity of all religions to attain the "real an sich". (shrink)

This essay discusses the Vietnam War from the perspective of the strategist, and with focus on men-power,which is part of the concept of `order of the battle’. The interest is progressing toward determining best methodsfor the calculation of estimates of this type to decrease mistake in wars that involve various nations. Uponstudying the debate involving the estimates for the Vietnam War, period ranging from 1965 to 1968, theconclusion is that there were gross mistakes from the part of the military, (...) and methods of producing the order ofthe battle have to be much better examined. Systems of decision, and management deserve revision, so that whathas happened during the Vietnam War does not repeat: important is saving human lives, not the prestige ofindividual institutions or even the amount of negative criticism that is made publicly available about them.National forces must mean also Academia, and there is a chance that Academia can improve those systems bymuch if governmental authorities acknowledge its existence in all sectors of the national life. The best strategyis still including the dissident group or person, not facing them as an enemy, when it comes to those who areregarded by the general public as part of the national forces. (shrink)

The paper argues that at present the Criminal law does not contain satisfactory rules for dealing with the circumstances in which a mistake can be taken to vitiate the victim's consent to an action or transaction. Rules on this issue vary both between different offences and within given offences in a way that is neither coherent nor predictable. As a matter of fact consent should be regarded as vitiated whenever the victim is under a misapprehension but for which (s)he (...) would not have given consent, but from a practical point of view it will not always be possible to allow this factual vitiation to have legal effect. To try to find a more satisfactory set of rules the paper offers a series of potential rules placed along a spectrum. Towards either end of the spectrum the rules have greater certainty and coherence, but produce less desirable results in terms of policy. Towards the centre of the spectrum the reverse is true. The paper therefore concludes that no single rule will be able to provide the answer to this area, and that an approach which recognises a series of circumstances in which consent will be regarded as legally vitiated should be retained instead. However, it is imperative that in future these categories be clearly, and predictably drawn and individually explicable and justifiable. As a starting point it is proposed that consent should be regarded as vitiated when the victim has made a non est factum mistake, has been mistaken about something which would render the action or transaction physically different from that expected, or where the victim believed that the defendant had a legal qualification which in fact (s)he lacked.

Allan Gibbard maintains that his plan-based expressivism allows for a particular type of innocent mistake: I can agree that your plan to X makes sense (say, because it was based on advice from someone you trust), while nonetheless insisting that it is incorrect (e.g., because you chose a bad advisor). However, Steve Daskal has recently argued that there are significant limitations in Gibbard’s account of how we can be mistaken about the normative judgments we make. This essay refines Gibbard’s (...) account in order to show--contra Daskal--that expressivists can deliver a surprisingly robust form of normative objectivity. (shrink)

More than a century ago, G. E. Moore famously attempted to refute ethical naturalism by offering the so-called open question argument (OQA), also charging that all varieties of ethical naturalism commit the naturalistic fallacy. Although there is consensus that OQA and the naturalistic-fallacy charge both fail, OQA is sometimes vindicated, but only as an argument against naturalistic semantic analyses. The naturalistic-fallacy charge, by contrast, usually finds no takers at all. This paper provides new grounds for an OQA thus restricted. But (...) it aims chiefly at vindicating a version of the naturalistic fallacy, „the semantic-naturalist fallacy‟ (SNF), that we think defensible. We first argue that the openness of the question OQA raises against such analyses hinges on self-ascriptive, comparative judgments of content, which may be considered a priori warranted. We then provide independent reasons for the claim that the sort of mistake committed by naturalistic analyses in fact amounts to a pragmatic fallacy of a kind familiar in petitio principii and other forms of viciously circular inference. Of interest here are naturalistic analyses of ethical terms or concepts, not of properties. Our OQA (OQA*) raises an objection to the former. For no such semantic analyses can get off the ground unless moral terms are content-equivalent to purely descriptive terms, which amounts to saying that they must instantiate the same semantic types. Suppose „good‟ is the analysandum and „pleasure maximizing‟ the analysans (whichever purely descriptive term or terms would turn out to be the correct descriptive analysis of the target analysandum) of a certain semantic analysis. The claim that such terms are content-equivalent appears to be open to doubt on a priori grounds. After 1 all, whether one‟s own tokens of „good‟ and „pleasure maximizing‟ have/don‟t have the same content is a first-person, comparative judgment of content. Evaluating the proposed analysis requires, then, a self-ascriptive, comparative judgment of content.1 Judgments of this sort are thought to have a special epistemic status, since they seem grounded in neither evidence nor inference..

Discussion of the behaviour of pregnant women and mothers, in academic literature, medical advice given to mothers, mainstream media and social media, assumes that a mother who fails to do something to benefit her child is liable for moral criticism unless she can provide sufficient countervailing considerations to justify her decision. I reconstruct the normally implicit reasoning that leads to this assumption and show that it is mistaken. First, I show that the discussion assumes that if any action might benefit (...) her child, the mother has a defeasible duty to perform that action. I suggest that this assumption is implicitly supported by two arguments but that each argument is unsound. The first argument conflates moral reasons and defeasible duties; the second misunderstands the scope of a defeasible duty to benefit. This argument has important practical and theoretical implications: practically, it provides a response to a highly damaging discourse on maternal behaviour; theoretically, it provides the framework for a clearer understanding of the scope and nature of defeasible duties to benefit.

Plato argues in Republic IX that people are often mistaken about their own pleasures and pains. One of the mistakes he focuses on isjudging that an experience of ours is pleasant when, in fact, it is not. The view that such a mistake is possible is an unpopular one, andscholars have generally been dismissive of Plato’s position. Thus Urmson argues not only that this position is deeply flawed, but alsothat it results from a confusion on Plato’s part. In this (...) paper, I show that Urmson’s criticism is misguided. I then defend Plato against theidea that it is impossible for someone to make the mistake in question. In doing so, I bring out details in Plato’s text and show that his account of the phenomenology involved in making this mistake is far more sophisticated than has so far been recognized. (shrink)

Wittgenstein’s Tractatus construes the nature of reasoning in a manner which sharply conflicts with the conventional wisdom that logic is normative, not descriptive of thought. For although we sometimes seem to reason incorrectly, Wittgenstein denies that we can make logical mistakes (5.473). My aim in this paper is to show that the Tractatus provides us with good reasons to rethink some of the central assumptions that are standardly made in thinking about the relation between logic and thought. In particular, the (...) rejection of logical mistakes is to be understood in connection with Wittgenstein’s non-psychological approach to the thinking subject (5.641). On Wittgenstein's view, inference, understanding, and meaning are holistically related; cases of defective reasoning are to be explained in terms of a defective grasp of meaning which manifests in an indeterminate use of signs. Invalid reasoning therefore does not count for Wittgenstein as a species of reasoning, but rather as the mere illusion of reasoning. The rejection of logical mistakes thus gives voice to a radical disjunctivist approach. (shrink)

What can we learn from cases of knowledge from falsehood? Critics of knowledge-first epistemology have argued that these cases provide us with good reason for rejecting the knowledge accounts of evidence, justification, and the norm of belief. I shall offer a limited defense of the knowledge-first approach to these matters. Knowledge from falsehood cases should undermine our confidence in like-from-like reasoning in epistemology. Just as we should be open to the idea that knowledge can come from non-knowledge, we should be (...) open to the idea that justified beliefs can come from unjustified beliefs. (shrink)

Timothy Williamson has famously argued that the principle should be rejected. We analyze Williamson's argument and show that its key premise is ambiguous, and that when it is properly stated this premise no longer supports the argument against. After canvassing possible objections to our argument, we reflect upon some conclusions that suggest significant epistemological ramifications pertaining to the acquisition of knowledge from prior knowledge by deduction.

Can we make mistakes about what rationality requires? A natural answer is that we can, since it is a platitude that rational belief does not require truth; it is possible for a belief to be rational and mistaken, and this holds for any subject matter at all. However, the platitude causes trouble when applied to rationality itself. The possibility of rational mistakes about what rationality requires generates a puzzle. When combined with two further plausible claims – the enkratic principle, and (...) the claim that rational requirements apply universally – we get the result that rationality generates inconsistent requirements. One popular and attractive solution to the puzzle denies that it is possible to make rational mistakes about what rationality requires. I show why (contra Titelbaum (2015b), and Littlejohn (2015)) this solution is doomed to fail. (shrink)

In this article, we aim to reveal the common mistakes made in the evaluation of the problem of evil from our perspective. Briefly, the problem of evil, which can be defined as “how evil can coexist with the existence of a good and almighty God”, is a problem that both theists and atheists might relate. The subject is important for theists because it is one of their existential questions and problems, and, perhaps, most of the time, it is the subject (...) of criticism of their beliefs. It is important for atheists as it is one of the most important intellectual grounds against theism. In this problem, the theism has been criticized from many points and many different answers have been given to these criticisms in this article, we will try to respond to these general criticisms from our perspective by showing the errors. considering the vast scope of the evil problem, this research is no means conclusive on the matter. It is our hope to contribute to the debate to make the problem of evil clearer for those who are interested in the topic. (shrink)

In this paper, I explore a line of argument against one form of realism about fictional characters : abstract artifact theory, the view according to which fictional characters like Harry Potter are part of our reality, but, they are abstract objects created by humans, akin to the institution of marriage and the game of soccer. I will defend artifactualism against an objection that Mark Sainsbury considers decisive against it: the category-mistake objection. The objection has it that artifactualism attributes to (...) people who produce and process sentences and thoughts about Harry Potter massive error, indeed, a category mistake about what kind of thing Harry Potter is; for an abstract object isn’t the sort of thing that can wear glasses, ride a double-decker bus, attend school. Given problems with this objection, artifactualism, I shall conclude, remains a tenable contender. (shrink)

In this paper I develop an objection to the version of expressivism found in Allan Gibbard’s book Thinking How to Live, and I suggest that the difficulty faced by Gibbard’s analysis is symptomatic of a problem for expressivism more generally. The central claim is that Gibbard’s expressivism is unable to account for certain normative judgments that arise in the process of evaluating cases of innocent mistakes. I begin by considering a type of innocent mistake that Gibbard’s view is able (...) to capture, one that can occur in situations in which our judgments of what it makes sense to do come apart from our judgments of what it makes sense to plan to do. Whether or not such mistakes are possible is a normative question, and I argue against Gibbard that we should adopt a normative stance that rules out such mistakes. This leads me to consider a second type of innocent mistake, one that can arise when an agent is constituted in such a way as to be incapable of recognizing the appropriate course of action. I argue here that our full normative assessment of the situation incorporates judgments that cannot be captured by Gibbard’s expressivism. I conclude by suggesting that any form of expressivism that shares Gibbard’s commitment to account for an intimate tie between normative judgments and action will face a similar problem. (shrink)

This Article falls into three general parts. The first part starts with an important question: is the insanity defense constitutionally required? The United States Supreme Court will finally try to answer this question next term in the case of Kahler v. Kansas. -/- I say “finally” because the Court refused to answer this question in 2012 when it denied certiorari to an appeal brought by John Joseph Delling, a severely mentally ill defendant who was sentenced to life in prison three (...) years earlier for two murders. Delling never had the opportunity to plead the insanity defense because his home state, Idaho, had abolished it in 1982. -/- By depriving Delling of the right to plead insanity, Idaho violated Delling’s Fourteenth Amendment right to due process and his Eighth Amendment right against “cruel and unusual” punishment. Naturally, the same is true for many other mentally ill and disabled defendants who have been prosecuted in Idaho and in the other three states that have abolished the insanity defense: Kansas, Montana, and Utah. -/- The second general part of this Article notes an insight that I stumbled upon in the course of researching the first part: the insanity defense and the mistake of law defense both require ignorance of the law, what I refer to as “normative ignorance.” Indeed, normative ignorance is what makes both of these defenses exculpatory in the first place. -/- Given this critical connection, there is a way for Idaho, Kansas, Montana, and Utah to resume compliance with the Constitution. Instead of reinstating the insanity defense per se, which might be politically unpopular, they should just broaden their mistake of law defense to include normative ignorance caused by cognitive incapacity that is itself caused by mental illness or disability. -/- Still, this Article is not merely directed at these four western states. It is directed at the other forty-six states as well. Because they already have an insanity defense, they need not incorporate it into their mistake of law defense. But in the third general part, I will argue that they should still expand their mistake of law defense to cover defendants who either lack a reasonable opportunity to learn the law or reasonably but mistakenly infer from widely accepted norms or ethics that their conduct is lawful.

[Stephen Yablo] The usual charge against Carnap's internal/external distinction is one of 'guilt by association with analytic/synthetic'. But it can be freed of this association, to become the distinction between statements made within make-believe games and those made outside them-or, rather, a special case of it with some claim to be called the metaphorical/literal distinction. Not even Quine considers figurative speech committal, so this turns the tables somewhat. To determine our ontological commitments, we have to ferret out all traces of (...) nonliterality in our assertions; if there is no sensible project of doing that, there is no sensible project of Quinean ontology. /// [Andre Gallois] I discuss Steve Yablo's defence of Carnap's distinction between internal and external questions. In the first section I set out what I take that distinction, as Carnap draws it, to be, and spell out a central motivation Carnap has for invoking it. In the second section I endorse, and augment, Yablo's response to Quine's arguments against Carnap. In the third section I say why Carnap's application of the distinction between internal and external questions runs into trouble. In the fourth section I spell out what I take to be Yablo's version of Carnap. In the last I say why that version is especially vulnerable to the objection raised in the second. (shrink)

Recent debate in the literature on political obligation about the principle of fairness rests on a mistake. Despite the widespread assumption to the contrary, a person can have a duty of fairness to share in the burdens of sustaining some cooperative scheme even though that scheme does not represent a net benefit to her. Recognizing this mistake allows for a resolution of the stalemate between those who argue that the mere receipt of some public good from a scheme (...) can generate a duty of fairness and those who argue that only some voluntary action of consent or acceptance of the good can generate such a duty. I defend a version of the principle of fairness that holds that it is the person’s reliance on a scheme for the provision of some product or service that generates duties of fairness to share in the burdens of sustaining the scheme. And, on this version, the principle of fairness is politically significant: regardless of whether the citizen has a duty to obey the law, she will still have important political duties of fairness generated by her reliance on the various public goods provided by those society-wide cooperative schemes sustained by the sacrifices of her fellow citizens.

In this commentary on Nuno Venturinha’s Description of Situations, after highlighting what in my view are the most significant and innovative features of his work, I focus on Venturinha’s infallibilist approach to knowledge. This topic allows for a wider discussion concerning the pragmatist aspects of the later Wittgenstein’s philosophy. I discuss this in three steps: first, by describing the general similarity between Wittgenstein and the pragmatists with respect to the emphasis on contexts; second, by focusing on the kind of fallibilism (...) endorsed by the pragmatists and its compatibility with Charles S. Peirce’s concept of the “indubitables,” which I take as a precursor of Wittgenstein’s concept of hinges; and, finally, by advancing the hypothesis that it is possible to find a form of fallibilism in the later Wittgenstein too, notwithstanding his insistence on the impossibility of mistakes. My conclusion is that while Venturinha’s contextualism finds support in the later Wittgenstein’s writings, his infallibilism does not. (shrink)

In a letter to William Molyneux John Locke states that in reviewing his chapter 'Of Power' for the second edition of An Essay Concerning Human Understanding he noticed that he had made one mistake which, now corrected, has put him "into a new view of things" which will clarify his account of human freedom.

In this paper, I argue that the method of cases (namely, the method of using intuitive judgments elicited by intuition pumps as evidence for and/or against philosophical theories) is not a reliable method of generating evidence for and/or against philosophical theories. In other words, the method of cases is unlikely to generate accurate judgments more often than not. This is so because, if perception and intuition are analogous in epistemically relevant respects, then using intuition pumps to elicit intuitive judgments is (...) like using illusions to elicit perceptual judgments. In both cases, judgments are made under bad epistemic circumstances. (shrink)

The concept of narrow content is still under discussion in the debate over mental representation. In the paper, one-factor dimensional accounts of representation are analyzed, particularly the case of Fodor's methodological solipsism. In methodological solipsism, semantic properties of content are arguably eliminated in favor of syntactic ones. If “narrow content” means content properties independent of external factors to a system (as in Segal's view), the concept of content becomes elusive. Moreover, important conceptual problems with one-factor dimensional account are pointed out (...) as a result of analysis arguments presented by J. Searle, S. Harnad and T. Burge. Furthermore, these problems are illustrated with psychological and ethological examples. Although understanding content as partially independent from contextual factors allows theorists to preserve content properties, it seems that understanding content in total abstraction from external factors of these properties is implausible. As a result, internalism is rejected in favor of externalism. (shrink)

I defend origins of life research against an argument, given by Roger White in 2007, that it rests on a mistake. I show how the Bayesian machinery can illuminate the rational search for alternative explanations of currently inexplicable, improbable data, and in particular how it can illuminate the rational search for a secular explanation of the origins of life and of the fine-tuning of the universe.

A self-fulfilling prophecy in neuroprognostication occurs when a patient in coma is predicted to have a poor outcome, and life-sustaining treatment is withdrawn on the basis of that prediction, thus directly bringing about a poor outcome for that patient. In contrast to the predominant emphasis in the bioethics literature, we look beyond the moral issues raised by the possibility that an erroneous prediction might lead to the death of a patient who otherwise would have lived. Instead, we focus on the (...) problematic epistemic consequences of neuroprognostic SFPs in settings where research and practice intersect. When this sort of SFP occurs, the problem is that physicians and researchers are never in a position to notice whether their original prognosis was correct or incorrect, since the patient dies anyway. Thus, SFPs keep us from discerning false positives from true positives, inhibiting proper assessment of novel prognostic tests. This epistemic problem of SFPs thus impedes learning, but ethical obligations of patient care make it difficult to avoid SFPs. We then show how the impediment to catching false positive indicators of poor outcome distorts research on novel techniques for neuroprognostication, allowing biases to persist in prognostic tests. We finally highlight a particular risk that a precautionary bias towards early withdrawal of life-sustaining treatment may be amplified. We conclude with guidelines about how researchers can mitigate the epistemic problems of SFPs, to achieve more responsible innovation of neuroprognostication for patients in coma. (shrink)

Sometimes we make mistakes, even when we try to do our best. When those mistakes are about normative matters, such as what is required, this leads to a puzzle. This puzzle arises from the possibility of misleading evidence about what rationality requires. I argue that the best way to solve this puzzle is to distinguish between two kinds of evaluation: requirement and appraisal. The strategy I defend connects three distinct debates in epistemology, ethics, and normativity: the debate over how our (...) theories of epistemic rationality should accommodate misleading evidence, the debate over the relationship between complying with requirements and deserving particular appraisals, and the debate over whether normative ignorance can excuse. Part 1 shows how three apparently plausible claims about epistemic rationality generate a puzzle when agents have misleading evidence about what rationality requires. Part 2 solves this puzzle by distinguishing between evaluations of requirement and appraisal and rejecting the idea that one is required to conform to the Enkratic Principle. I argue instead that complying with the Enkratic Principle provides defeasible evidence that the agent should be positively appraised. One of the consequences of this solution is that false normative beliefs can sometimes excuse agents from negative appraisal they would otherwise deserve for violating requirements. Part 3 defends the view that false normative belief can sometimes excuse against the rival views that false normative belief always excuses, and that false normative belief never excuses. I argue that false normative belief can sometimes excuse violations of requirements, when it is the case that the agent has done what it is reasonable to expect of her. (shrink)

In this paper I argue against Twin-Earth externalism. The mistake that Twin Earth arguments rest on is the failure to appreciate the force of the following dilemma. Some features of things around us do matter for the purposes of conceptual classification, and others do not. The most plausible way to draw this distinction is to see whether a certain feature enters the cognitive perspective of the experiencing subject in relation to the kind in question or not. If it does, (...) we can trace conceptual differences to internal differences. If it doesn’t, we do not have a case of conceptual difference. Neither case supports Twin Earth externalism. (shrink)

‘Transplant’ thought-experiments, in which the cerebrum is moved from one body to another, have featured in a number of recent discussions in the personal identity literature. Once taken as offering confirmation of some form of psychological continuity theory of identity, arguments from Marya Schechtman and Kathleen Wilkes have contended that this is not the case. Any such apparent support is due to a lack of detail in their description or a reliance on predictions that we are in no position to (...) make. I argue that the case against them rests on two serious misunderstandings of the operation of thought-experiments, and that even if they do not ultimately support a psychological continuity theory, they do major damage to that theory’s opponents.

The present article discusses the measurement of social class in the social psychology of education research. It was evident that social class experiences are conflated with the socioeconomic status indicators and the subjective measure of the class context was underrepresented. However, this was discussed in Rubin et al about the intersectional nature of social class taking into account both objective and subjective indicators. The derivation of the social class experience from the objective and subjective measures were critically discussed. An effort (...) was made to understand whether these translations are category mistake or not. Three trajectories will be utilized to address the category mistake, that is, 1) subjectivity and objectivity debate in the measurement of social class in social psychology of education, 2) debates encircling around the position of social psychology and its underutilized concept such as social class as scientifically objective facets in social sciences and 3) operationalism of social class and category mistake.

This is an attempt to axiomatise the natural laws. Note especially axiom 4, which is expressed in third order predicate logic, and which permits a solution to the problem of causation in nature without stating that “everything has a cause”. The undefined term “difference” constitutes the basic element and each difference is postulated to have an exact position and to have a discrete cause. The set of causes belonging to a natural set of dimensions is defined as a law. This (...) means that a natural law is determined by the discrete causes tied to a natural set of dimensions. A law is defined as “defined” in a point if a difference there has a cause. Given that there is a point for which the law is not defined it is shown that a difference is caused that connects two points in two separate sets of dimensions. (shrink)

Rationality requires that our mental attitudes exhibit specific patterns of coherence. Do we have reason to comply? 'Prichardian Quietists' regard this question as fundamentally confused: the only reasons to comply with rational requirements are the ones given by the requirements themselves. In this paper, I argue that PQ fails. I proceed by granting that Prichard's own position, from which PQ draws inspiration, is defensible, while identifying three serious problems with the parallel position about rationality. First, as I argue, PQ is (...) not plausibly combined with either the narrow-scope or the wide-scope formulations of rational requirements. Second, PQ implies that the reasons to comply with rational requirements are reasons of the wrong kind. And finally, PQ lacks a crucial component of its explanation, viz. a plausible theory of what constitutes being rationally required to V. (shrink)

As its title indicates, Philip Pettit’s “Three Mistakes about Doing Good (and Bad)” identifies and rejects three common claims restricting what can count as a good (or bad ) effect of action. The key question here is how do we work out how much good you have brought about by your action? The first common claim is that only causal effects or consequences of action can count as goods that are brought about by an action. The second, that we can (...) only count behavioural effects of action. The third, that we can only count consequences of “an all-or-nothing or on-off or discrete kind”. Pettit argues that all three of these claims are mistaken: the first claim is mistaken because our actions can bring about goods that are constitutive consequences of those actions; the second claim is mistaken because the good consequences of an action can depend upon the agent having acted out of certain dispositions; the third claim is mistaken because the good consequences of an action can include the extra effects of pursuing more basic good consequences (such as benefits to others) in a more deliberate or reliable manner.

There are two ways that we might respond to the underdetermination of theory by data. One response, which we can call the agnostic response, is to suspend judgment: "Where scientific standards cannot guide us, we should believe nothing". Another response, which we can call the fideist response, is to believe whatever we would like to believe: "If science cannot speak to the question, then we may believe anything without science ever contradicting us". C.S. Peirce recognized these options and suggested evading (...) the dilemma. It is a Logical Maxim, he suggests, that there could be no genuine underdetermination. This is no longer a viable option in the wake of developments in modern physics, so we must face the dilemma head on. The agnostic and fideist responses to underdetermination represent fundamentally different epistemic viewpoints. Nevertheless, the choice between them is not an unresolvable struggle between incommensurable worldviews. There are legitimate considerations tugging in each direction. Given the balance of these considerations, there should be a modest presumption of agnosticism. This may conflict with Peirce's Logical Maxim, but it preserves all that we can preserve of the Peircean motivation. (shrink)

John Greco claims that knowledge is a kind of achievement. The value achievements have (as such) shows, according to Greco, why knowledge is better than mere true belief. I argue that, for a variety of reasons, it is not always good to know. Furthermore, it is wrong to think that achievements are always good – think of achieving what is bad. Greco is mistaken twice; this leaves the idea that knowledge is a kind of achievement intact.

Within the social sciences, much controversy exists about which status should be ascribed to the rationality assumption that forms the core of rational choice theories. Whilst realists argue that the rationality assumption is an empirical claim which describes real processes that cause individual action, instrumentalists maintain that it amounts to nothing more than an analytically set axiom or ‘as if’ hypothesis which helps in the generation of accurate predictions. In this paper, I argue that this realist-instrumentalist debate about rational choice (...) theory can be overcome once it is realised that the rationality assumption is neither an empirical description nor an ‘as if’ hypothesis, but a normative claim.

The aim of this paper is to clarify the truth-functional interpretation of the logical connective of the material implication. The importance of such clarification lies in the fact that it allows avoiding the supposed paradoxes introduced by C. I. Lewis (1918). I argue that an adequate understanding of the history and purposes of logic is enough to dissolve them away. The defense is based on an exposition of propositional compositionalism. To compare, I also present Stalnaker’s (1968) alternative that seeks to (...) explain the implicit concept of conditionality of conditionals assertions. In order to reinforce my aim I expound the twelve different meanings of ‘implication’ stated by Corcoran (1993) in order to hold that a proper understanding of these meanings allows us to avoid ambiguities and confusions. Finally, I expect to show that despite the possible alternatives, compositionalism is still the best explanation for the truth-functionality account of logical connectives. (shrink)

I argue that the dispute between two leading theories of interpretation of legal texts, textual originalism and textual evolutionism, depends on the false presupposition that changes in the way a word is used necessarily require a change in the word’s meaning. Semantic externalism goes a long way towards reconciling these views by showing how a word’s semantic properties can be stable over time, even through vicissitudes of usage. I argue that temporal externalism can account for even more semantic stability, however. (...) Temporal externalism is the theory that the content of an utterance at time t may be determined by developments in linguistic usage subsequent to t. If this semantic theory is correct, then the originalist and evolutionist positions effectively collapse. Originalism is correct in that the original meaning of the text is the meaning that is binding on jurists, but evolutionism is vindicated, as it is the current practices and standards that determine the meaning the text now has, and has always had. Objections to temporal externalism, and to its application to the interpretation of legal texts, are considered and addressed. (shrink)
