In the late summer of 1998, the authors, a cognitive scientist and a logician, started talking about the relevance of modern mathematical logic to the study of human reasoning, and we have been talking ever since. This book is an interim report of that conversation. It argues that results such as those on the Wason selection task, purportedly showing the irrelevance of formal logic to actual human reasoning, have been widely misinterpreted, mainly because the picture of logic current in psychology (...) and cognitive science is completely mistaken. We aim to give the reader a more accurate picture of mathematical logic and, in doing so, hope to show that logic, properly conceived, is still a very helpful tool in cognitive science. The main thrust of the book is therefore constructive. We give a number of examples in which logical theorizing helps in understanding and modeling observed behavior in reasoning tasks, deviations of that behavior in a psychiatric disorder (autism), and even the roots of that behavior in the evolution of the brain.

This chapter seeks to make a contribution to the growing interest in Nietzsche's relation to traditions of therapy in philosophy that has emerged in recent years. It is in the texts of his middle period that Nietzsche's writing comes closest to being an exercise in philosophical therapeutics, and in this chapter I focus on Dawn from 1881 as a way of exploring this. Dawn is a text that has been admired in recent years for its ethical naturalism and for its (...) anticipation of phenomenology. My interest in the text in this chapter is in the way it revitalises for a modern age ancient philosophical concerns, notably a teaching for mortal souls who wish to be liberated from the fear and anguish of existence, as well as from God, the ‘metaphysical need’, and romantic music, and are able to affirm their mortal conditions of existence. As a general point of inspiration I have adopted Pierre Hadot's insight into the therapeutic ambitions of ancient philosophy which was, he claims, ‘intended to cure mankind's anguish’. This is evident in the teaching of Epicurus which sought to demonstrate the mortality of the soul and whose aim was, ‘to free humans from “the fears of the mind”.’ Similarly, Nietzsche's teaching in Dawn is for mortal souls. In the face of the loss of the dream of the soul's immortality, philosophy for Nietzsche, I shall show, has new consolations to offer in the form of new sublimities. Indeed, for Nietzsche it is by reflecting, with the aid of psychological observation, on what is ‘human, all too human’, that ‘we can lighten the burden of life’. Nietzsche's thinking in Dawn contains a number of proposals and recommendations of tremendous value to philosophical therapeia, including a call for a new honesty about the human ego and human relations, including relations of self and other and love, so as to free us from certain delusions; the search for an authentic mode of existence which appreciates the value of solitude and independence; the importance of having a rich and mature taste in order to eschew the fanatical. After an introduction to Nietzsche's text the chapter is divided into two main parts. In the first main part I explore various aspects of his conception of philosophical therapy, including purification of the higher feelings and liberation from the destructive effects of ‘morality’ and Christianity. In the second main part I explore his conception of ‘the passion of knowledge’, which is the passion that guides modern free spirits as they seek to overcome the need of religion and constraints of ‘morality’, and to access the new sublimities of philosophy.

Consider the following argument written on the board in room 227: 1 = 1. So, the argument on the board in room 227 is not valid. This argument generates a paradox. The aim of this paper is to present a resolution of this paradox and related paradoxes of validity, including a version of the Curry paradox. The proposal stresses the close connections between these validity paradoxes and paradoxes of truth and paradoxes of denotation. So a more general aim is to (...) provide a unified response to semantic paradox. The positive proposal is in part inspired by a brief, tantalizing suggestion of Gödel’s, that the paradoxes might appear “as something analogous to dividing by zero”—so that the concept of validity, for example, is everywhere applicable except for certain singular points or singularities. A second central claim is that ‘valid’ is a context-sensitive predicate. The key notions of this contextual-singularity theory are presented and applied to a variety of cases. Any purported solution to paradox must deal with the phenomenon of revenge, and a response to revenge is outlined. The paper closes with remarks about the accommodation of Tarski’s claim that natural languages are universal. (shrink)

A Curry paradox about truth is generated by the following sentence, written on the board in room 101:If the sentence on the board in room 101 is true then 1 ≠ 1.A Curry paradox about validity is generated by the following argument, written on the board in room 102:The argument on the board in room 102 is valid. Therefore, 1 ≠ 1.Though the sentence and the argument generate Curry paradoxes, they also generate more basic paradoxes, in a sense to be (...) made clear. I argue that if we solve these more basic paradoxes, we have solutions to both kinds of Curry paradox. The positive proposal is in part inspired by a brief remark of Gödel’s, that the paradoxes might appear “as something analogous to dividing by zero”—so that the concepts of truth and validity, for example, are everywhere applicable except for certain singular points or singularities. A second central claim is that 'true' and 'valid' are context-sensitive predicates. This contextual-singularity approach to the Curry paradoxes applies also to other paradoxes of truth, validity, denotation, and predicate-extension. So a more general aim of the paper is to provide a unified response to semantic paradox. (shrink)

The dual role of olfaction in both smelling and tasting, i.e. flavour perception, makes it an important test case for philosophical theories of sensory individuation. Indeed, the psychologist Paul Rozin claimed that olfaction is a “dual sense”, leading some scientists and philosophers to propose that we have not one, but two senses of smell: orthonasal and retronasal olfaction. In this paper I consider how best to understand Rozin’s claim, and upon what grounds one might judge there to be one or (...) two distinct olfactory modalities. I conclude that while Rozin may be right that humans have dual occurrences of an olfactory ‘sense’, the concept of a sense-modality, and hence the ‘sense’ of smell, is ambiguous between two different notions: a physiological sensory channel and an experiential modality, along the lines suggested by J. J. Gibson. Furthermore, recognising that these are complementary rather than competing conceptions of a sense-modality enables the formulation of a powerful ‘dual-concept’ framework for posing and addressing questions concerning the complex architecture of human multisensory experience.

Contemporary virtue ethics was revolutionized by Alasdair MacIntyre’s reconfiguration using practices as the starting point for understanding virtues. However, MacIntyre has very pointedly excluded the professions of the financial world from the reformulation. He does not count these professions as practices, and further charges that virtue would actually hinder or even rule out one’s pursuit of these professions. This paper addresses three tasks, in regard to the financial profession of investment advising. First, the paper lays out MacIntyre’s soon-to-be-published charges against (...) the investment world, as specified to this profession. Second, it sets forth the role function of investment advising and shows that it does possess internal goods—the crucial aspect of practices disputed by MacIntyre in this case—including goods of production and goods of performance. Third, it demonstrates that this function, and the goods tied to it, cannot be achieved apart from the virtuous pursuit of the profession, thereby showing that MacIntyre’s charges are mistaken. Investment advising is shown to be a virtue-based practice, and the groundwork is laid for showing that other financial professions are so, as well. (shrink)

This paper offers a brief comment on Jennings’ preceding paper, focusing on the capacity of a republican approach to public health ethics to facilitate reconceptualization of the right to health in situations of limited resources through a relational reading.

In a 2022 paper, Hamami claimed that the orthodox view in mathematics is that a proof is rigorous if it can be translated into a derivation. Hamami then developed a descriptive account that explains how mathematicians check proofs for rigor in this sense and how they develop the capacity to do so. By exploring introductory texts in computability theory, we demonstrate that Hamami’s descriptive account does not accord with actual mathematical practice with respect to computability theory. We argue instead for (...) an alternative account in which imagination, anticipation, and interpretations of natural language play roles in establishing mathematical rigor. (shrink)

The discourses of agricultural extension reveal how actors represent their scientific activities and goals. The “transfer of technology” discourse developed with the professional U.S. extension service, reproducing its expert/lay power relations. Agroecology is emerging as a systems approach to preventing agricultural pollution. Its theoreticians argue that agroecology cannot be transferred like technology but must be extended through networks of participatory social learning. In California, hundreds of actors and dozens of institutions have cocreated agroecological partnerships using this alternative extension model. They (...) have developed three alternative extension discourses to represent and explain their activities. Bruno Latour's “circulatory system of science” model provides a superior theoretical framework for interpreting the participation and discourses of diverse actors in this extension practice.

My argument is that naturalism is too restricted and dogmatic an account of the many different sorts of entities and explanations that we employ in trying to understand our world. It is a faith rather than a mode of inquiry.

Is it possible to remember Hiroshima and, if it is, what exactly is being remembered? This paper uses Resnais’s film Hiroshima Mon Amour as a way of asking this question. The problem of remembering is identified as being due to how nuclear explosions are beyond the human capacity to understand. The paper draws on the work of Günther Anders to explore the implications of Hiroshima for the human understanding of human possibilities.

In this paper I present two new paradoxes, a definability paradox (related to the paradoxes of Berry, Richard and König), and a paradox about extensions (related to Russell’s paradox). However, unlike the familiar definability paradoxes and Russell’s paradox, these new paradoxes involve no self-reference or circularity.

Religion is an important social force, both for good and evil, in the modern world. This book considers the main ways in which religion and society interact, and the ways in which the major world religions need to adapt themselves in the modern world. The author, a Christian theologian, describes the major types of religious community in the world, and proposes a radical vision of the church as a person-affirming, world-transforming society in the emerging global community of many faiths and (...) cultures.

Some texts appear more than once across the corpus of Zygmunt Bauman’s work. This has led to accusations of self-plagiarism and a lack of scholarly rigour. This paper is an explanation of why texts reappear. It pays attention to a number of frequently overlooked texts from the 1970s which are of fundamental importance for any understanding of Bauman’s work. It is contended that if: (a) there is an understanding of the stakes and purpose of sociology as it is framed in (...) Bauman’s work; and (b) attention is paid to the argument of Hermeneutics and Social Science; then (c) the repetition of texts across the work becomes explicable and unproblematic. The paper argues that dealings with Bauman’s work need to be more aware of the less well-known texts. They also need to be alert to different – and incommensurable – ways of practising sociology.

A relatively under-analysed theme in the sociology of the media is the moral consequentiality for television viewers of representations and reports of the suffering of others. The theme has been broached by Michael Ignatieff, and this article uses an essay by him as an opportunity to develop the thesis that any consideration of the relationship between television and morality must centrally concern itself with the complex exchanges between television and its viewers. The article seeks to offer some initial themes and (...) theses about the moral consequentiality of television. (shrink)

Previous research on associative learning has uncovered detailed aspects of the process, including what types of things are learned, how they are learned, and where in the brain such learning occurs. However, perceptual processes, such as stimulus recognition and identification, take time to unfold. Previous studies of learning have not addressed when, during the course of these dynamic recognition processes, learned representations are formed and updated. If learned representations are formed and updated while recognition is ongoing, the result of learning (...) may incorporate spurious, partial information. For example, during word recognition, words take time to be identified, and competing words are often active in parallel. If learning proceeds before this competition resolves, representations may be influenced by the preliminary activations present at the time of learning. In three experiments using word learning as a model domain, we provide evidence that learning reflects the ongoing dynamics of auditory and visual processing during a learning event. These results show that learning can occur before stimulus recognition processes are complete; learning does not wait for ongoing perceptual processing to complete. (shrink)

Courts are increasingly obliged to adjudicate upon challenges to allocative decisions in healthcare, but their involvement continues to be regarded with unease, imperilling the legitimacy of the judicial role in this context. A central reason for this is that judges are perceived to lack sufficient expertise to determine allocative questions. This article critically appraises the claim of lack of judicial expertise through an examination of the various components of a limit-setting decision. It is argued that the inexpertise argument is weak (...) when compared with other rationales for judicial restraint, such as the procedural unsuitability and lack of constitutional competence of courts.

At 14 months, children appear to struggle to apply their fairly well-developed speech perception abilities to learning similar sounding words (e.g., bih/dih; Stager & Werker, 1997). However, variability in nonphonetic aspects of the training stimuli seems to aid word learning at this age. Extant theories of early word learning cannot account for this benefit of variability. We offer a simple explanation for this range of effects based on associative learning. Simulations suggest that if infants encode both noncontrastive information (e.g., cues (...) to speaker voice) and meaningful linguistic cues (e.g., place of articulation or voicing), then associative learning mechanisms predict these variability effects in early word learning. Crucially, this means that despite the importance of task variables in predicting performance, this body of work shows that phonological categories are still developing at this age, and that the structure of noninformative cues has critical influences on word learning abilities.

The vision of global health with justice which Larry Gostin articulates in his book Global Health Law envisages a switch to ‘upstream’ priority-setting for expenditure on health, with a focus upon social determinants and a goal of redressing health inequalities. This article explores what is meant by this proposal and offers a critical evaluation of it. It is argued that difficulties arise in respect of the ethical and evidential bases for such an approach to the setting of priorities, while significant (...) challenges may also arise in the necessary modification of structures of governance.
