Three experiments are reported which show that in certain contexts subjects reject instances of the valid modus ponens and modus tollens inference form in conditional arguments. For example, when a conditional premise, such as: If she meets her friend then she will go to a play, is accompanied by a conditional containing an additional requirement: If she has enough money then she will go to a play, subjects reject the inference from the categorical premise: She meets her friend, to the (...) conclusion: She will go to a play. Other contexts suppress the conditional fallacies. The first experiment demonstrates the effects of context on conditional reasoning. The second experiment shows that the inference suppression disappears when the categorical premise refers to both of the antecedents, such as: She meets her friend and she has enough money. In this case, subjects make both the valid inferences and the fallacies, regardless of the contextual information. The third experiment establishes that when subjects are given general information about the duration of a situation in which a conditional inducement was uttered, such as: If you shout then I will shoot you, they reject both the valid inferences and the fallacies. The results suggest that the interpretation of premises plays an even more central role in reasoning than has previously been admitted. Trois expériences montrent que dans certains contextes les sujets rejettent des instances valides de modus ponens et de modus tollens dans des énoncés conditionnels. Par exemple, quand une prémisse conditionnelle comme: Si elle rencontre son ami, alors elle ira jouer, est accompagnée par une phrase contenant une condition supplémentaire: Si elle a assez d'argent, alors elle ira jouer, les sujets rejettent l'inférence liant la prémisse catégorielle: Elle rencontre son ami, à la conclusion: Elle ira jouer. D'autres contextes éliminent également les inférences conditionnelles fallacieuses. La premiére expérience démontre l'effet du contexte sur la raisonnement conditionnel. La deuxiéme expérience montre que la suppression de l'inférence disparait quand la prémisse catégorielle fait référence aux deux antécédants, comme: Elle rencontre son ami et elle a assez d'argent. Dans ce cas, les sujets font aussi bien les inférences valides et fallacieuses, quelle que soit l'information contextuelle. La troisiéme expérience établit que quand l'on donne aux sujets des informations générales à propos de la durée d'une situation dans laquelle une conditionnelle a été prononcée, comme Si tu cries, alors je te tire dessus, ils rejettent autant les inférences valides que les inférences fallacieuses. Ces résultats suggèrent que l'interprétation des prémisses joue un rŏle encore plus central dans le raisonnement que l'on admettait auparavant. (shrink)

Polls suggest up to twenty percent of Americans describe their beliefs as 'libertarian', but libertarians are often derided as heartless Social Darwinists or naïve idealists. This illuminating handbook brings together scholars from a range of fields and political perspectives to consider how classical liberal principles can help us understand and potentially address a variety of pressing social problems including immigration, climate change, the growth of the prison population, and a host of others. Anyone interested in political theory or practical law (...) and politics will find this book an essential resource for understanding this major strand of American politics. (shrink)

Resumen: El artículo contribuye al esfuerzo colectivo de mostrar que la tutela judicial de los derechos sociales es posible analizando la jurisprudencia reciente del TEDH. Propone la reconstrucción de una teoría unitaria de los derechos y analiza dos de los obstáculos para consolidarla: la diferencia entre las obligaciones que establecen los derechos civiles y los sociales, y la tesis de la justiciabilidad débil. Para contrastarlos, por un lado, se identifican algunos caminos que el TEDH ha elaborado a través de una (...) interpretación creativa del Pacto, y por otro, se descartan otros mecanismos de tutela a la luz de la jurisprudencia reciente. Abstract: This work aims at contributing to the collective effort of demonstrating that protecting social rights is possible under the ECHR. Departing from a unitary theory of rights, it provides evidences about how the ECTHR has recognised the posibility of judicial adjudication of social rights either through new forms of litigation or a creative interpretation of the Convention. Finally, it evaluates the posibilities of protecting social rights through the general prohibition of discrimination by analysing recent case law of the ECTHR. (shrink)

In this book, first published in 1975, Dr Kempson argues that previous work on presupposition - whether in philosophy or linguistics - has been mistakenly based on a conflation of two different disciplines: semantics, the study of the meanings assigned to the formal system which constitutes a language, and pragmatics, the study of the use of that system in communication. The first part of the book deals generally with the nature of semantics in linguistic theory and its formal representation within (...) a transformational grammar; Dr Kempson argues against incorporating the relation of presupposition within such a grammar. The second part provides a pragmatic account of the foundations of a theory of communication and its detailed application to the problems raised by presupposition. The book is intended for those studying both philosophy and linguistics and also for those sociolinguists and psychologists with a more general interest in the theory of communication. (shrink)

In this paper I discuss two views that focus on the natural environment, namely (1) a western or “W” view (hereafter W) basedloosely on the kind of liberal outlook offered by John Rawls in A Theory of Justice and (2) a primal or “P” view (hereafter, P) stemming from environmental teachings of primal peoples. I suggest that while the W tradition has produced many truly helpful and comfortable amenities, it is nevertheless oriented toward commitments to resource acquisition and “detached” objectivity (...) of sorts that could ultimately lead human beings down paths of predictable and tragic destruction. I conclude that P needs to be seriously considered and, where possible, utilized to remold W to achieve a view with maximal environment-preserving possibilities. (shrink)

Advocates for the professionalization of clinical bioethics argue that bioethics professionals play an important role in contemporary medicine and patient care, especially when addressing complex ethical questions that arise in the delivery of reproductive medicine. For bioethics consultants to serve effectively, they need adequate training in the medical and ethical issues that patients and clinicians will face, and they need skills to facilitate effective dialog among all parties. Because clinical ethics consultation is a “high‐stakes endeavor” that can acutely affect patient (...) care, efforts are under way to ensure that bioethics consultants have the competence to provide such guidance. Yet to date, no studies have examined whether the training of bioethics consultants meets the needs of health care professionals who are on the front lines of such issues. In fact, limited information is available on the reproductive health issues that bioethics training programs address or the degree to which these programs meet the needs of patients confronting reproductive health decisions and their clinicians. It is therefore important to answer this key question: What are the primary ethical issues encountered in reproductive medicine that currently affect patient care? Equally important, are bioethics training programs prepared to address those issues?To begin to answer these questions, we conducted parallel surveys of directors of graduate bioethics training programs and obstetrician‐gynecologists. The goal of this project is to lay the groundwork to establish a working partnership between bioethics educators and reproductive medicine practitioners to address the often troubling and frequently complex ethical issues in reproductive medicine.

Semantics is a bridge discipline between linguistics and philosophy; but linguistics student are rarely able to reach that bridge, let alone cross it to inspect and assess the activity on the other side. Professor Kempson's textbook seeks particularly to encourage such exchanges. She deals with the standard linguistic topics like componential analysis, semantic universals and the syntax-semantics controversy. But she also provides for students with no training in philosophy or logic an introduction to such central topics in the philosophy of (...) language as logical form, truth, speech acts, analyticity, entailment and presupposition. The exposition throughout is deliberately argumentative rather than descriptive, introducing the student step by step to the major problems in theoretical semantics. Special emphasis is placed on the need to consider individual arguments within the overall perspective of semantics as an integral part of general linguistic theory. Written primarily as a textbook for undergraduates and graduates in linguistics departments, this book will also be useful to undergraduates in philosophy and in psychology where linguistics is a part of their course.

In the opening sections of this paper, we defined ambiguity in terms of distinct sentences (for a single sentence-string) with, in particular, distinct sets of truth conditions for the corresponding negative sentence-string. Lexical vagueness was defined as equivalent to disjunction, for under conditions of the negation of a sentence-string containing such an expression, all the relevant more specific interpretations of the string had also to be negated. Yet in the case of mixed quantification sentences, the strengthened, more specific, interpretations of (...) some such positive string are not all of them necessarily implied to be false if the corresponding negative sentence-string is asserted. On the contrary, as we saw in section 6, a negative sentence-string can be used to deny one of the more specific interpretations of the corresponding positive string without also denying other weaker interpretations of that same string. One might therefore argue that the only empirical evidence availble for assessing quantified sentences suggests clearly that these sentence-strings are ambiguous. Indeed logicians, many of whom restrict their attention to propositions, MUST recognise logical ambiguity at this point. For the contextualisation of the negative sentences in section 6 showed that it was possible to assert the falsity of some proposition P expressed by the sentence S while asserting a further proposition which was compatible with the truth of S. However the corresponding conclusion that such sentence-strings are sententially ambiguous is not a necessary conclusion for the linguist: for the alternative account of postulating a single semantic representation plus a set of semantic procedures is also compatible with the negation evidence. Moreover we have seen independent reasons for thinking that if sentential ambiguity is assumed to be in one-to-one correspondence with what we should now call logical ambiguity, a considerable body of generalisations is lost. For the maximal ambiguity account, it should be recalled, is committed to assigning at least thirteen distinct propositions and hence thirteen distinct sentence outputs for every sentence-string containing no more than two quantifiers, for three out of the four interpretations originally outlined in this paper can be understood with each numeral taken either in an ’exactly’ sense or in an ’at least’ sense. Moreover there is no explanation of why just these interpretations are available-they are merely an arbitrary list, no more connected than are the two interpretations of John saw her duck, with no reason to predict that the ambiguity would carry over from language to language. If then it is granted that an ambiguity account fails to capture appropriate generalisations, only two alternative accounts of mixed quantification sentence-strings remain viable-an analysis proposing an initial co-ordinate logical form like the logical form III, which is the strongest form compatible with each of the propositional interpretations of sentence-string Two examiners marked six scripts, and the radically weak form in which only existential quantification (both over sets and over members of those sets) is invoked. Since there are strong arguments to suggest that the procedures which both analyses require are semantic, there seems no reason not to adopt the radical vagueness account, with its considerably greater simplicity.

Simple Heuristics That Make Us Smart invites readers to embark on a new journey into a land of rationality that differs from the familiar territory of cognitive science and economics. Traditional views of rationality tend to see decision makers as possessing superhuman powers of reason, limitless knowledge, and all of eternity in which to ponder choices. To understand decisions in the real world, we need a different, more psychologically plausible notion of rationality, and this book provides it. It is about (...) fast and frugal heuristics--simple rules for making decisions when time is pressing and deep thought an unaffordable luxury. These heuristics can enable both living organisms and artificial systems to make smart choices, classifications, and predictions by employing bounded rationality. But when and how can such fast and frugal heuristics work? Can judgments based simply on one good reason be as accurate as those based on many reasons? Could less knowledge even lead to systematically better predictions than more knowledge? Simple Heuristics explores these questions, developing computational models of heuristics and testing them through experiments and analyses. It shows how fast and frugal heuristics can produce adaptive decisions in situations as varied as choosing a mate, dividing resources among offspring, predicting high school drop out rates, and playing the stock market. As an interdisciplinary work that is both useful and engaging, this book will appeal to a wide audience. It is ideal for researchers in cognitive psychology, evolutionary psychology, and cognitive science, as well as in economics and artificial intelligence. It will also inspire anyone interested in simply making good decisions. (shrink)

: In this paper, I consider some issues concerning Hume’s epistemology of testimony. I’ll particularly focus on the accusation of reductivism and individualism brought by scholars against Hume’s view on testimonial evidence, based on the tenth section of his An enquiry concerning human understanding. I first explain the arguments against Hume’s position, and address some replies in the literature in order to offer an alternative interpretation concerning the way such a defense should go. My strategy is closely connected with Hume’s (...) notion of virtue and the role it plays in his epistemology, mainly as presented in his A treatise of human nature. I address the problem of how the section “Of miracles” in the Enquiry must be properly understood, as several misunderstandings of Hume’s epistemology of testimony emerge partially from the particular character and aim of that section. Resumen: En este artículo, considero algunas cuestiones relacionadas con la epistemología del testimonio de David Hume. El eje central será la acusación de reductivismo e individualismo de los estudiosos en contra de la opinión de Hume sobre la evidencia testimonial. Dicha acusación se basa en su tratamiento de los reportes sobre hechos milagrosos, presente en la sección X de su Investigación sobre el entendimiento humano. En primer lugar, se abordan los argumentos en contra de la posición de Hume y algunas respuestas en la literatura reciente, para luego ofrecer una interpretación alternativa con respecto a la forma en que debería articularse esa defensa. Mi estrategia está estrechamente relacionada con la noción de virtud de Hume y el papel que desempeña en su epistemología, principalmente como se presenta en su Tratado de la naturaleza humana. Finalmente, abordaré el problema relacionado con la forma en que debe entenderse correctamente la sección “Of miracles” de la Investigación, ya que varios malentendidos sobre la epistemología del testimonio de Hume emergen parcialmente del carácter particular y el objetivo de dicho ensayo.

From the stance of cognitive developmental theories, claims that general g is an entity of the mind are compatible with notions about domain-general development and age-invariant individual differences. Whether executive function is equated with general g or fluid g, research into the mechanisms by which development occurs is essential to elucidate the kinds of environmental inputs that engender effective intervention.

En este artículo se abordan las perspectivas de David Hume y Bertrand Rus-sell en tormo dos asuntos estrechamente vinculados, a saber, el problema de la justificación de la inferencia no demostrativa y de la validez del principio de causalidad, ambos configu-ran el así llamado “problema de Hume”. Desde una perspectiva analítica y comparativa, se intenta mostrar que a pesar de la lectura fuertemente crítica que Russell adopta respecto del filósofo escocés, ambos filósofos comparten en cierta medida un programa filosófico común. (...) En este contexto se hacen notar algunas distinciones de importancia pasadas a menudo por alto en la discusión especializada, que permiten concluir que la teoría de Russell del conoci-miento está en realidad alineada con la del empirista moderno, y por tanto, que es también susceptible de las mismas críticas.

People judge that an individual who attempts to harm someone but fails should be blamed and punished more when they imagine how things could have turned out worse, compared to when they imagine how things could have turned out the same, or when they think only about what happened. This moral counterfactual amplification effect occurs when people believe the protagonist had no reason for the attempt to harm, and not when the protagonist had a reason, as Experiment 1 shows. It (...) occurs for intentional failed attempts to harm and also for accidental near-misses, as Experiment 2 shows, but not for failed attempts in which the harm occurs anyway by another cause, for both general judgments about the event and specific judgments about the individual's actions, as Experiments 3 and 4 show. The implications for understanding the role of counterfactual thoughts in moral judgement are discussed. (shrink)

Four studies show that observers and readers imagine different alternatives to reality. When participants read a story about a protagonist who chose the more difficult of two tasks and failed, their counterfactual thoughts focused on the easier, unchosen task. But when they observed the performance of an individual who chose and failed the more difficult task, participants' counterfactual thoughts focused on alternative ways to solve the chosen task, as did the thoughts of individuals who acted out the event. We conclude (...) that these role effects may occur because participants' attention is engaged when they experience or observe an event more than when they read about it. (shrink)

Philosophy of Linguistics investigates the foundational concepts and methods of linguistics, the scientific study of human language. This groundbreaking collection, the most thorough treatment of the philosophy of linguistics ever published, brings together philosophers, scientists and historians to map out both the foundational assumptions set during the second half of the last century and the unfolding shifts in perspective in which more functionalist perspectives are explored. The opening chapter lays out the philosophical background in preparation for the papers that follow, (...) which demonstrate the shift in the perspective of linguistics study through discussions of syntax, semantics, phonology and cognitive science more generally. The volume serves as a detailed introduction for those new to the field as well as a rich source of new insights and potential research agendas for those already engaged with the philosophy of linguistics. It provides a bridge between philosophy and current scientific findings, encourages multi-disciplinary dialogue, and covers theory and applications. (shrink)

This article presents a fundamental advance in the theory of mental models as an explanation of reasoning about facts, possibilities, and probabilities. It postulates that the meanings of compound assertions, such as conditionals (if) and disjunctions (or), unlike those in logic, refer to conjunctions of epistemic possibilities that hold in default of information to the contrary. Various factors such as general knowledge can modulate these interpretations. New information can always override sentential inferences; that is, reasoning in daily life is defeasible (...) (or nonmonotonic). The theory is a dual process one: It distinguishes between intuitive inferences (based on system 1) and deliberative inferences (based on system 2). The article describes a computer implementation of the theory, including its two systems of reasoning, and it shows how the program simulates crucial predictions that evidence corroborates. It concludes with a discussion of how the theory contrasts with those based on logic or on probabilities. (shrink)

When people think about how a situation might have turned out differently, they tend to imagine counterfactual alternatives to their actions. We report the results of three experiments which show that people imagine alternatives to actions differently when they know about a reason for the action. The first experiment ( n = 36) compared reason - action sequences to cause - effect sequences. It showed that people do not imagine alternatives to reasons in the way they imagine alternatives to causes: (...) they imagine an alternative to an action more than an effect, and to a cause more than a reason. The second experiment ( n = 214) and the third experiment ( n = 190) both show that different sorts of reasons have different sorts of effects on how people imagine alternatives to actions. People imagine an alternative to an action (the protagonist went to a ball) less often when they know the reason for the action was an obligation (he had to participate in fundraising) compared to when they know about a weaker reason (he wanted to meet a famous violinist) or no reason. The second experiment shows the effect for a social obligation and the third experiment replicates and extends it to a health obligation. We interpret the results in terms of the possibilities that people keep in mind about actions and their reasons. (shrink)

Many proteins responsible for genome maintenance interact with one another via short sequence motifs. The best known of these are PIP motifs, which mediate interactions with the replication protein PCNA. Others include RIR motifs, which bind the translesion synthesis protein Rev1, and MIP motifs, which bind the mismatch repair protein Mlh1. Although these motifs have similar consensus sequences, they have traditionally been viewed as separate motifs, each with their own target protein. In this article, we review several recent studies that (...) challenge this view. Taken together, they imply that these different motifs are not distinct entities. Instead, there is a single, broader class of motifs, which we call “PIP‐like” motifs, which have overlapping specificities and are capable of binding multiple target proteins. Given this, we must reassess the role of these motifs in forming the network of interacting proteins responsible for genome maintenance. (shrink)

Semifactual thinking about what might have been the same, e.g., ''even if Philip had not chosen the chocolate ice-cream sundae, he would have developed an allergic reaction'' has been neglected compared to counterfactual thinking about what might have been different, e.g., ''if only Philip had not chosen the chocolate ice-cream sundae, he would not have developed an allergic reaction''. We report the first systematic comparison of the two sorts of thinking in two experiments. The first experiment showed that counterfactual ''if (...) only'' thoughts about an antecedent event lead people to judge the event to be more causally related to the outcome, whereas semifactual ''even if'' thoughts lead people to judge the antecedent event to be less causally related to the outcome. In addition, the experiment showed that generating counterfactual ''if only'' thoughts increases emotional reactions such as regret, whereas generating semifactual ''even if'' thoughts decreases such reactions. The second experiment, along with a replication experiment, showed that when people complete ''if only'' and ''even if'' sentence stems, they focus on different alternative antecedents to the outcome: ''if only'' thoughts focus on alternatives that would undo the outcome whereas ''even if'' thoughts focus on alternatives that would not undo it, from among a set of available alternative antecedents in which either all, some, or none would undo the outcome. The implications of the results for theories of thinking about what might have been are discussed. (shrink)

There can be no doubt that discrimination based on sex, race, ethnicity, religion or beliefs should not be tolerated in academia. Surprisingly, however, in recent years, policies of Diversity, Inclusion and Equity (DIE), officially introduced to counteract discrimination, have increasingly led to quite the opposite result: the exclusion of individuals who do not share a radical 'woke' ideology on identity politics (feminism, other gender activisms, critical race theory, etc.), and to the suppression of the academic freedom to discuss such dogmas. (...) This subversion of academia — disguised Trojan-horse style as universal human rights advocacy — is unacceptable because academia must be politically neutral and protect freedom of speech, a cornerstone of professional scholarly activity without which universities as we know them will slowly but surely suffocate. Our purpose here is to put together some particularly illustrative cases of such repression in a single book, testifying to a ubiquitous trend within western culture, irreducible to a few isolated complaints. The essays contained here illustrate the abuse of power, censorship and witch-hunts at many universities and research centres in the name of DIE.

We examined how people think about how things could have turned out differently after they made a decision to cooperate or not in three social interactions: the Prisoner’s dilemma (Experiment 1), the Stag Hunt dilemma (Experiment 2), and the Chicken game (Experiment 3). We found that participants who took part in the game imagined the outcome would have been different if a different decision had been made by the other player, not themselves; they did so whether the outcome was good (...) or bad for them, their own choice had been to cooperate or not, and the other player’s choice had been to cooperate or not. Participants who only read about a fictional protagonist’s game imagined changes outside the protagonist’s control (such as the other player’s decision) after a good outcome but within the protagonist’s control (such as the protagonist’s decision) after a bad outcome. The implications for theories of counterfactual thinking and moral decision-making are discussed. (shrink)
