Compare your pain when immersing your hand in freezing water and your pleasure when you taste your favourite wine. The relationship seems obvious. Your pain experience is unpleasant, aversive, negative, and bad. Your experience of the wine is pleasant, attractive, positive, and good. Pain and pleasure are straightforwardly opposites. Or that, at any rate, can seem beyond doubt, and to leave little more to be said. But, in fact, it is not beyond doubt. And, true or false, it leaves a (...) good deal more to be said: about the nature of sensory affect; its relations to perception, motivation, and rationality; its value; and the mechanisms underlying it. Much is said about these matters in the contributions that follow. Here, in this introductory essay, we map the dialectical landscape and locate our contributors’ papers within it. (shrink)

Fifty years have passed since Norwood Russell Hanson's unexpected death, yet he remains an important voice in philosophy of science. This book is a revised and expanded edition of a collection of Hanson's essays originally published in 1971, edited by Stephen Toulmin and Harry Woolf. The new volume features a comprehensive introduction by Matthew Lund (Rowan University) and two new essays. The first is "Observation and Explanation: A Guide to Philosophy of Science", originally published as a posthumous book by (...) Harper and Row. This essay, written near the end of Hanson’s life, represents his mature philosophy of science. The second new addition, Hanson's essay "The Trial of Galileo", is something of a "lost" work – it was only published in a small run collection on famous trials and was left out of the published lists of Hanson’s works. Ever the outspoken firebrand, Hanson found many lessons and warnings from Galileo's trial that were relevant to Cold War America. -/- This volume not only contains Hanson's best-known work in history and philosophy of science, but also highlights the breadth of his philosophical thought. Hanson balanced extreme versatility with a unified approach to conceptual and philosophical problems. Hanson's central insight is that philosophy and science both strive to render the world intelligible -- the various concepts central to our attempts to make sense of the world are interdependent, and cannot operate, or even be fully understood, independently. The essays included in this collection present Hanson's thinking on religious belief, theory, observation, meaning, cosmology, modality, logic, and philosophy of mind. This collection also includes Hanson's lectures on the theory of flight, Hanson's greatest passion. (shrink)

This paper deals with a collection of concerns that, over a period of time, led the author away from the Routley–Meyer semantics, and towards proof- theoretic approaches to relevant logics, and indeed to the weak relevant logic MC of meaning containment.

This special issue for the Journal for General Philosophy of Science is devoted to exploring the impact and many ramifications of current research in evolutionary epistemology. Evolutionary epistemology is an inter- and multidisciplinary area of research that can be divided into two ever-inclusive research avenues. One research avenue expands on the EEM program and investigates the epistemology of evolution. The other research avenue builds on the EET program and researches the evolution of epistemology. Since its conception, EE has developed three (...) schools of thought: adaptationist, non-adaptationist, and applied EE. Although diverse in outlook and theoretical background, these research avenues and schools share the same agenda of understanding how knowledge evolves, and how it relates to the world. In this paper, we first explain wherefrom evolutionary epistemological schools of thought developed, and then we highlight current debates in EE by briefly reviewing the papers that form part of this special issue.

Norwood Russell Hanson was one of the most important philosophers of science of the post-war period. Hanson brought Wittgensteinian ordinary language philosophy to bear on the concepts of science, and his treatments of observation, discovery, and the theory-ladenness of scientific facts remain central to the philosophy of science. Additionally, Hanson was one of philosophy’s great personalities, and his sense of humor and charm come through fully in the pages of Perception and Discovery. -/- Perception and Discovery, originally published in 1969, (...) is Hanson’s posthumous textbook in philosophy of science. The book focuses on the indispensable role philosophy plays in scientific thinking. Perception and Discovery features Hanson’s most complete and mature account of theory-laden observation, a discussion of conceptual and logical boundaries, and a detailed treatment of the epistemological features of scientific research and scientific reasoning. This book is of interest to scholars of philosophy of science, particularly those concerned with Hanson’s thought and the development of the discipline in the middle of the 20th century. However, even fifty years after Hanson’s early death, Perception and Discovery still has a great deal to offer all readers interested in science. (shrink)

Over recent decades, pain has received increasing attention as – with ever greater sophistication and rigour – theorists have tried to answer the deep and difficult questions it poses. What is pain’s nature? What is its point? In what sense is it bad? The papers collected in this volume are a contribution to that effort ...

The present discussion takes up an issue raised in Section 5 of Ross Brady and Penelope Rush’s paper ‘Four Basic Logical Issues’ concerning the (claimed) triviality – in the sense of automatic availability – of soundness and completeness results for a logic in a metalanguage employing at least as much logical vocabulary as the object logic, where the metalogical behaviour of the common logical vocabulary is as in the object logic. We shall see – in Propositions 4.5–4.7 – that (...) this triviality claim faces difficulties in the face of Halldén incompleteness, for essentially the same reasons that Halldén thought this phenomenon raised seman- tic difficulties for the modal logics of C. I. Lewis exhibiting it. To counter any inclination to dismiss the phenomenon as providing at best a marginal range of counterexamples to the triviality claim, a Postscript assembles some reminders of the extent of – and the varied considerations favouring – Halldén incompleteness.

The book is addressed to all readers interested in cognitive science, and especially in research combining a logical analysis with psychological, linguistic and neurobiological approaches. The publication is the result of a collaboration between the Department of Cognitive Science at University of Lodz and the Department of Cognitive Science at Lund University. It is intended to provide a comprehensive presentation of the key research issues undertaken in both Departments, including considerations on meaning, natural language and reasoning, linguistic as well (...) as numerical competence, the theory of decision making, modelling of conceptual representations, cognitive and game theoretic approach to social interactions.

Harm is a concept in philosophy that has been able to elude definition. Many attempts have been made to formulate a definition of harm, however they have all been futile. This has led many to question if it is even possible to define harm, or if we really even need a definition of harm? My answer to both of these questions is yes, harm is something that is worth caring about and has many practical implications in society today. The theories (...) of harm that have been the closest thus far have been comparative accounts of harm, which compare different states of the agent undergoing the harm. The most common of these comparative accounts has been the counterfactual comparative account of harm. This approach has faced many problems like preemption, overdetermination, and omission. I argue the comparative account of harm is correct, but the wrong comparison is being made. Instead of a counterfactual comparison we should make a temporal comparison, and evaluate whether or not the agent has become worse off than he or she was before the harming event occurred. First I will use Bradley’s model to sketch a brief definition checklist of harm. I will then briefly evaluate a general counterfactual theory of harm and illustrate why it falls short. Next I will pose the temporal comparative account of harm , and explain how it gets around the counterexamples that tripped up the counterfactual approach. Finally I will present some objections to TCA, and try to respond to them. (shrink)

Formal symptoms of relevance usually concern the propositional variables shared between the antecedent and the consequent of provable conditionals. Among the most famous results about such symptoms are Belnap’s early results showing that for sublogics of the strong relevant logic R, provable conditionals share a signed variable between antecedent and consequent. For logics weaker than R stronger variable sharing results are available. In 1984, Ross Brady gave one well-known example of such a result. As a corollary to the main (...) result of the paper, we give a very simple proof of a related but strictly stronger result. (shrink)

This paper offers a qualified defense of a historically popular view that I call sentimental perceptualism. At a first pass, sentimental perceptualism says that emotions play a role in grounding evaluative knowledge analogous to the role perceptions play in grounding empirical knowledge. Recently, András Szigeti and Michael Brady have independently developed an important set of objections to this theory. The objections have a common structure: they begin by conceding that emotions have some important epistemic role to play, but then (...) go on to argue that understanding how emotions play that role means that there must be some alternative, emotion-independent route to obtaining knowledge of value. If there has to be such an emotion-independent route, then the perceptual analogy breaks down in a significant way. In this paper, I argue that the right ways for sentimental perceptualists to respond to each of these objections are revealed by thinking through how analogous objections applied to perception and the empirical domain would be answered. Although Szigeti's and Brady's objections should not persuade sentimental perceptualists to give up their view, the objections do put important constraints on what a form of the view has to be like in order to do exciting metaethical work.

In this chapter we suggest that many experiences of suffering can be further illuminated as forms of transformative experience, using the term coined by L.A. Paul. Such suffering experiences arise from the vulnerability, dependence, and affliction intrinsic to the human condition. Such features can create a variety of positively, negatively, and ambivalently valanced forms of epistemically and personally transformative experiences, as we detail here. We argue that the productive element of suffering experiences can be articulated as transformative, although suffering experiences (...) are not the type mostly discussed in the transformative experience literature. We correct for this here by developing a taxonomy of negatively valenced transformative experiences. We suggest three features that make such experiences ones of suffering, following Michael Brady’s definition: intensity, novelty, and attentional focus. Finally, we suggest that one possible explanation for the edifying capacity of suffering comes from it requiring more transformation than positive experiences. (shrink)

The naive theory of properties states that for every condition there is a property instantiated by exactly the things which satisfy that condition. The naive theory of properties is inconsistent in classical logic, but there are many ways to obtain consistent naive theories of properties in nonclassical logics. The naive theory of classes adds to the naive theory of properties an extensionality rule or axiom, which states roughly that if two classes have exactly the same members, they are identical. In (...) this paper we examine the prospects for obtaining a satisfactory naive theory of classes. We start from a result by Ross Brady, which demonstrates the consistency of something resembling a naive theory of classes. We generalize Brady’s result somewhat and extend it to a recent system developed by Andrew Bacon. All of the theories we prove consistent contain an extensionality rule or axiom. But we argue that given the background logics, the relevant extensionality principles are too weak. For example, in some of these theories, there are universal classes which are not declared coextensive. We elucidate some very modest demands on extensionality, designed to rule out this kind of pathology. But we close by proving that even these modest demands cannot be jointly satisfied. In light of this new impossibility result, the prospects for a naive theory of classes are bleak. (shrink)

Recalcitrant emotions are emotions that conflict with your evaluative judgements, e.g. fearing flying despite judging it to be safe. Drawing on the work of Greenspan and Helm, Brady argues these emotions raise a challenge for a theory of emotion: for any such theory to be adequate, it must be capable of explaining the sense in which subjects that have them are being irrational. This paper aims to raise scepticism with this endeavour of using the irrationality shrouding recalcitrant episodes to (...) inform a theory of emotion. I explain how ‘recalcitrant emotions’ pick out at least two phenomena, which come apart, and that there are different epistemic norms relevant to assessing whether, and if so how, subjects undergoing recalcitrant bouts are being irrational. I argue these factors result in differing accounts of the precise way these emotions make their bearers irrational, which in turn frustrates present efforts to adjudicate whether a given theory of emotion successfully meets this challenge. I end by briefly exploring two possible ways a philosophy of emotion might proceed in the face of such scepticism. (shrink)

This article aims to provide a response to the problem of suffering through an explication of a new theodicy termed the Exemplarist Theodicy. This specific theodicy will be formulated in light of the moral theory provided by Linda Zagzebski, termed the Exemplarist Moral Theory, the notion of transformative experience, as explicated by L.A. Paul, Havi Carel and Ian James Kidd, and the virtue-theoretic approach to suffering proposed by Michael Brady, which, in combination with some further precisifying philosophical concepts—namely, compensation, (...) total empathy, and infinitely valuable connections—will provide us with a possible, morally sufficient reason for why God allows individuals to experience suffering.

The project “A Plurality of Lives” was funded and hosted by the Pufendorf Institute for Advanced Studies at Lund University, Sweden. The aim of the project was to better understand how a second origin of life, either in the form of a discovery of extraterrestrial life, life developed in a laboratory, or machines equipped with abilities previously only ascribed to living beings, will change how we understand and relate to life. Because of the inherently interdisciplinary nature of the project (...) aim, the project took an interdisciplinary approach with a research group made up of 12 senior researchers representing 12 different disciplines. The project resulted in a joint volume, an international symposium, several new projects, and a network of researchers in the field, all continuing to communicate about and advance the aim of the project.

Sokrates var inte bara en filosofisk nydanare. Genom sitt sätt att involvera sina samtalspartners i den filosofiska processen var han också i hög utsträckning en pedagogisk nydanare. Hans pedagogiska grundidé var den så kallade majeutiska metoden – det vill säga ”barnmorskemetoden”. Med det menade han att han inte överförde sina egna färdiga tankar till den han talade med utan han hjälpte sin samtalspartner att föda sina egna tankar. Inom pedagogiken är det vanligt att använda den så kallade ”Sokratiska metoden” vilket (...) i sin enklaste form bara innebär att man ställer frågor till studenterna. Den här artikeln kommer emellertid att handla om en mer sofistikerad metod som används för begreppsanalys/begreppsdefinition i grupp. Metoden är inspirerad av Sokrates men skiljer sig också en del från hur Sokrates själv grep sig an sina dialoger – åtminstone så som de beskrivs av Platon. Artikeln innehåller en kort historisk och pedagogisk bakgrund men syftar framför allt till att utgöra en praktisk vägledning för genomförande av sokratiska dialoger i filosofiundervisningen. Artikeln bygger framför allt på mina egna erfarenheter av att använda Sokratisk Dialog i undervisningen vid Filosofiska institutionen vid Lunds universitet, Lunds Tekniska Högskola, Sveriges Lantbruksuniversitet och i det privata näringslivet. Artikeln vänder sig till alla som undervisar i filosofi på universitetet eller gymnasiet eller i filosofiska metoder för studenter vid andra utbildningar, t.ex. värdeteori, vetenskapsteori eller tillämpad etik för ingenjörer eller medicinare – eller i vilket annat ämne som helst där det förekommer begrepp som saknar en enkel och knivskarp definition men som är viktiga för ämnet.

The study of active matter systems demonstrates how interactions might co-constitute agential dynamics. Active matter systems are comprised of self-propelled independent entities which, en masse, take part in complex and interesting collective group behaviors at a far-from-equilibrium state (Menon, 2010 ; Takatori & Brady, 2015 ). These systems are modelled using very simple rules (Vicsek at al. 1995), which reveal the interactive nature of the collective behaviors seen from humble to highly complex entities. Here I show how the study (...) of active matter systems supports two related proposals regarding interaction and agency. First, I argue that the study of interactive dynamics in these systems evidences the utility of treating interaction as an ontological category (Longino, 2021 ) and challenges methodological individualism as the received explanatory primitive in the study of agency. Second, the methods used to research active matter systems demonstrate how a minimal approach to agency can scale up in studying interactive agential dynamics in more complex systems. The examples of coordination dynamics (Kelso, 2001 ) and participatory sense-making (De Jaegher & Di Paolo, 2007 ) are provided to show how understanding agency requires us to look beyond the individuals to the interactive agential dynamics that can guide, scaffold, or constrain their activity.

What is meaning-making? How do new domains of meanings emerge in the course of child’s development? What is the role of consciousness in this process? What is the difference between making sense of pointing, pantomime and language utterances? Are great apes capable of meaning-making? What about dogs? Parrots? Can we, in any way, relate their functioning and behavior to a child’s? Are artificial systems capable of meaning-making? The above questions motivated the emergence of cognitive semiotics as a discipline devoted to (...) theoretical and empirical studies of meaning-making processes. As a transdisciplinary approach to meaning and meaning-making, cognitive semiotics necessarily draws on a different disciplines: starting with philosophy of mind, via semiotics and linguistics, cognitive science(s), neuroanthropology, developmental and evolutionary psychology, comparative studies, and ending with robotics. The book presents extensively this discipline. It is a very eclectic story: highly abstract problems of philosophy of mind are discussed and, simultaneously, results of very specific experiments on picture recognition are presented. On the one hand, intentional acts involved in semiotic activity are elaborated; on the other, a computational system capable of a limited interpretation of excerpts from Carroll’s Through the Looking-Glass is described. Specifically, the two roads to cognitive semiotics are explored in the book: phenomenological-enactive path developed by the so-called Lund school and author’s own proposal: a functional-cognitivist path.

Experiencing tragedy may broaden our ability to understand the suffering of others, and further our ability to endure future suffering. In the work of stoic philosopher Epictetus, he proports one should practice premeditatio malorum, preparing for the tragedies to come so that when they do occur one will be less disturbed. Through the stories of those that have survived tragedy and great suffering though, we can grow to understand the choices people make that lead to suffering are often the lesser (...) of two evils. When man sees a reason to suffer, he will choose to suffer, it is possible to understand and explain what experiencing suffering causes. The writings of philosophical professor Michael Brady, Susan Feagin, and others explain that the virtues of suffering are enough so we should not avoid the experience of it. We study history so that we may avoid repeating it, and just the same we experience the suffering that comes naturally throughout life so that we may avoid repeating it. (shrink)
