I propose to consider the question, "Can machines think?" This should begin with definitions of the meaning of the terms "machine" and "think." The definitions might be framed so as to reflect so far as possible the normal use of the words, but this attitude is dangerous, If the meaning of the words "machine" and "think" are to be found by examining how they are commonly used it is difficult to escape the conclusion that the meaning and the answer to (...) the question, "Can machines think?" is to be sought in a statistical survey such as a Gallup poll. But this is absurd. Instead of attempting such a definition I shall replace the question by another, which is closely related to it and is expressed in relatively unambiguous words. The new form of the problem can be described in terms of a game which we call the 'imitation game." It is played with three people, a man (A), a woman (B), and an interrogator (C) who may be of either sex. The interrogator stays in a room apart front the other two. The object of the game for the interrogator is to determine which of the other two is the man and which is the woman. He knows them by labels X and Y, and at the end of the game he says either "X is A and Y is B" or "X is B and Y is A." The interrogator is allowed to put questions to A and B. We now ask the question, "What will happen when a machine takes the part of A in this game?" Will the interrogator decide wrongly as often when the game is played like this as he does when the game is played between a man and a woman? These questions replace our original, "Can machines think?". (shrink)

We are all concerned by the environmental threats facing us today. Environmental issues are a major area of concern for policy makers, industrialists and public groups of many different kinds. While science seems central to our understanding of such threats, the statements of scientists are increasingly open to challenge in this area. Meanwhile, citizens may find themselves labelled as "ignorant" in environmental matters. In Citizen Science Alan Irwin provides a much needed route through the fraught relationship between science, the (...) public and the environmental threat. (shrink)

Misunderstanding Science? offers a challenging new perspective on the public understanding of science. In so doing, it also challenges existing ideas of the nature of science and its relationships with society. Its analysis and case presentation are highly relevant to current concerns over the uptake, authority, and effectiveness of science as expressed, for example, in areas such as education, medical/health practice, risk and the environment, technological innovation. Based on several in-depth case-studies, and informed theoretically by the sociology of scientific knowledge, (...) the book shows how the public understanding of science questions raises issues of the epistemic commitments and institutional structures which constitute modern science. It suggests that many of the inadequacies in the social integration and uptake of science might be overcome if modern scientific institutions were more reflexive and open about the implicit normative commitments embedded in scientific cultures.

Many explanations in science make use of mathematics. But are there cases where the mathematical component of a scientific explanation is explanatory in its own right? This issue of mathematical explanations in science has been for the most part neglected. I argue that there are genuine mathematical explanations in science, and present in some detail an example of such an explanation, taken from evolutionary biology, involving periodical cicadas. I also indicate how the answer to my title question impacts on broader (...) issues in the philosophy of mathematics; in particular it may help platonists respond to a recent challenge by Joseph Melia concerning the force of the Indispensability Argument.

'Working Memory, Thought, and Action' is the magnum opus of one of the most influential cognitive psychologists of the past 50 years. This new volume on the model he created discusses the developments that have occurred within the model in the past twenty years, and places it within a broader context.

Does mathematics ever play an explanatory role in science? If so then this opens the way for scientific realists to argue for the existence of mathematical entities using inference to the best explanation. Elsewhere I have argued, using a case study involving the prime-numbered life cycles of periodical cicadas, that there are examples of indispensable mathematical explanations of purely physical phenomena. In this paper I respond to objections to this claim that have been made by various philosophers, and I discuss (...) potential future directions of research for each side in the debate over the existence of abstract mathematical objects.

Psychologists and philosophers have recently been exploring whether the mechanisms which underlie the acquisition of ‘theory of mind’ (ToM) are best charac- terized as cognitive modules or as developing theories. In this paper, we attempt to clarify what a modular account of ToM entails, and why it is an attractive type of explanation. Intuitions and arguments in this debate often turn on the role of develop- ment: traditional research on ToM focuses on various developmental sequences, whereas cognitive modules are thought (...) to be static and ‘anti-developmental’. We suggest that this mistaken view relies on an overly limited notion of modularity, and we explore how ToM might be grounded in a cognitive module and yet still afford development. Modules must ‘come on-line’, and even fully developed modules may still develop internally, based on their constrained input. We make these points con- crete by focusing on a recent proposal to capture the development of ToM in a module via parameterization. (shrink)

How might social theory, public understanding of science and science policy best inform one another? What have been the key features of science-society relations in the modern world? How are we to re-think science-society relations in the context of globalization, hybridity and changing patterns of governance? This topical and unique book draws together the three key perspectives on science-society relations: public understanding of science, scientific and public governance, and social theory. The book presents a series of case studies (including the (...) debates on genetically modified foods and the AIDS movement in the USA) to discuss critically the ways in which social theorists, social scientists, and science policy makers deal with science-society relations. ‘Science' and 'society' combine in many complex ways. Concepts such as citizenship, expertise, governance, democracy and the public need to be re-thought in the context of contemporary concerns with globalization and hybridity. A radical new approach is developed and the notion of ethno-epistemic assemblage is used to articulate a new series of questions for the theorization, empirical study and politics of science-society relations.

An explanation is given of why it is in the nature of inquiry into whether or not p that its aim is fully achieved only if one comes to know that p or to know that not-p and, further, comes to know how one knows, either way. In the absence of the latter one is in no position to take the inquiry to be successfully completed or to vouch for the truth of the matter in hand. An upshot is that (...) although knowledge matters because truth matters this should not be understood to mean that knowledge matters because true belief matters. (shrink)

When communal sharing relationships suddenly intensify, people experience an emotion that English speakers may label, depending on context, “moved,” “touched,” “heart-warming,” “nostalgia,” “patriotism,” or “rapture”. We call the emotion kama muta. Kama muta evokes adaptive motives to devote and commit to the CSRs that are fundamental to social life. It occurs in diverse contexts and appears to be pervasive across cultures and throughout history, while people experience it with reference to its cultural and contextual meanings. Cultures have evolved diverse practices, (...) institutions, roles, narratives, arts, and artifacts whose core function is to evoke kama muta. Kama muta mediates much of human sociality. (shrink)

We discuss a recent attempt by Chris Daly and Simon Langford to do away with mathematical explanations of physical phenomena. Daly and Langford suggest that mathematics merely indexes parts of the physical world, and on this understanding of the role of mathematics in science, there is no need to countenance mathematical explanation of physical facts. We argue that their strategy is at best a sketch and only looks plausible in simple cases. We also draw attention to how frequently Daly and (...) Langford find themselves in conflict with mathematical and scientific practice. (shrink)

It is a common complaint that antireductionist arguments are primarily negative. Here I describe an alternative nonreductionist epistemology based on considerations taken from multidisciplinary research in biology. The core of this framework consists in seeing investigation as coordinated around sets of problems (problem agendas) that have associated criteria of explanatory adequacy. These ideas are developed in a case study, the explanation of evolutionary innovations and novelties, which demonstrates the applicability and fruitfulness of this nonreductionist epistemological perspective. This account also bears (...) on questions of conceptual change and theory structure in philosophy of science. †To contact the author, please write to: Department of Philosophy, University of Minnesota, 831 Heller Hall, 271 19th Ave. S., Minneapolis, MN 55455; e‐mail: [email protected].

Interest in ethical leadership from academics and practitioners has grown enormously in recent years. This article addresses this literature through a framework that identifies three interlocking questions. First, who are ethical leaders and what are their characteristics? Second, how do ethical leaders do what they do? Third, why do leaders do as they do and what are the outcomes of ethical leadership? Different dimensions to ethical leadership are examined and presented as three interlocking circles; Virtues, Purposes and Practices. This framework (...) presents an integrated approach to ethical leadership and argues that future research take this holistic framework and apply it to different sectors or contexts. (shrink)

The first work to introduce Foucault's ideas on law to both graduates and undergraduates.

According to one popular nominalist picture, even when mathematics features indispensably in scientific explanations, this mathematics plays only a purely representational role: physical facts are represented, and these exclusively carry the explanatory load. I think that this view is mistaken, and that there are cases where mathematics itself plays an explanatory role. I distinguish two kinds of explanatory generality: scope generality and topic generality. Using the well-known periodical-cicada example, and also a new case study involving bicycle gears, I argue that (...) what is picked out by the mathematics are structural facts that go beyond any specific physical facts.

The economic crisis is also a crisis for economic theory. Most analyses of the evolution of the crisis invoke three themes, contagion, networks and trust, yet none of these play a major role in standard macroeconomic models. What is needed is a theory in which these aspects are central. The direct interaction between individuals, firms and banks does not simply produce imperfections in the functioning of the economy but is the very basis of the functioning of a modern economy. This (...) book suggests a way of analysing the economy which takes this point of view. The economy should be considered as a complex adaptive system in which the agents constantly react to, influence and are influenced by, the other individuals in the economy. In such systems which are familiar from statistical physics and biology for example, the behaviour of the aggregate cannot be deduced from the behaviour of the average, or "representative" individual. Just as the organised activity of an ants’ nest cannot be understood from the behaviour of a "representative ant" so macroeconomic phenomena should not be assimilated to those associated with the "representative agent". This book provides examples where this can clearly be seen. The examples range from Schelling’s model of segregation, to contributions to public goods, the evolution of buyer seller relations in fish markets, to financial models based on the foraging behaviour of ants. The message of the book is that coordination rather than efficiency is the central problem in economics. How do the myriads of individual choices and decisions come to be coordinated? How does the economy or a market, "self organise" and how does this sometimes result in major upheavals, or to use the phrase from physics, "phase transitions"? The sort of system described in this book is not in equilibrium in the standard sense, it is constantly changing and moving from state to state and its very structure is always being modified. The economy is not a ship sailing on a well-defined trajectory which occasionally gets knocked off course. It is more like the slime described in the book "emergence", constantly reorganising itself so as to slide collectively in directions which are neither understood nor necessarily desired by its components.

Philosophers of mathematics have become increasingly interested in the explanatory role of mathematics in empirical science, in the context of new versions of the Quinean ‘Indispensability Argument’ which employ inference to the best explanation for the existence of abstract mathematical objects. However, little attention has been paid to analysing the nature of the explanatory relation involved in these mathematical explanations in science (MES). In this paper, I attack the only articulated account of MES in the literature (an account sketched by (...) Mark Steiner), according to which a genuine MES incorporates an explanatory proof of the mathematical result being used. The central case study involves an explanation for why bees build the cells of their honeycombs in the shape of hexagons. I make a distinction between two kinds of MES, mathematics-driven explanation in science and science-driven mathematical explanation, and argue that it is the second category which is both scientifically and philosophical more central. I conclude that the explanatory relation involved in MES is genuinely scientific and hence that the phenomenon of MES poses a challenge to general accounts of scientific explanation. (shrink)

Actualists who believe in possible worlds typically regard them as "abstract" objects of some special sort. For example, Alvin Plantinga takes worlds to be maximal possible states-of-affairs, all of which "exist", as actualism requires, but only one of which "obtains". Views like Plantinga's run into difficulty in the interpretation of statements of "iterated" modality, statements about what is "possible" for individuals that "could" exist but that do not actually exist. These statements seem to require the existence of "singular" states-Of-affairs that (...) have nonactual individuals as constituents, a requirement that is incompatible with actualism. One can try to avoid the troublesome singular states-of-affairs by introducing "unexemplified individual essences" and maintaining that these are the true constituents of the required states-of-affairs, rather than the nonactual possibles themselves. However, serious arguments are raised against this employment of individual essences. (shrink)

The relationship between religiosity and ethical behavior at work has remained elusive. In fact, inconsistent results in observed magnitudes and direction led Hood et al. (The psychology of religion: An empirical approach, 1996 ) to describe the relationship between religiosity and ethics as “something of a roller coaster ride.” Weaver and Agle (Acad Manage Rev 27(1):77–97, 2002 ) utilizing social structural versions of symbolic interactionism theory reasoned that we should not expect religion to affect ethical outcomes for all religious individuals; (...) rather, such a relationship likely depends on specific religious attitudes including religious motivation orientation (intrinsic RMO vs. extrinsic RMO), perceived sacred qualities of work (job sanctification), and views of God (VOG, loving vs. punishing). We examined the effects of these three religious attitudes on participants’ judgments of 29 ethically questionable vignettes. Consistent with symbolic interactionism theory, intrinsic RMO and having a loving view of God were both negatively related to endorsing ethically questionable vignettes, whereas extrinsic RMO was positively related to endorsing the vignettes. Unexpectedly, job sanctification was positively related to endorsing the vignettes. However, both intrinsic and extrinsic RMO moderated this relationship such that sanctifying one’s job was related to ethical judgments only for those who were: (a) low in intrinsic RMO or (b) high in extrinsic RMO. We reasoned based on symbolic interactionism theory that intrinsically motivated participants, in contrast to extrinsically motivated participants, may have utilized their religious beliefs as a guiding framework in making ethical judgments.

This paper discusses comparison classes—sets that relativize the interpretation of gradable adjectives, often specified with for-clauses as in John is smart for a linguist. Such a discussion ultimately lends support to the thesis that scales, degrees, measure functions, and linear orders are grammatically derived from more basic relations between individuals. Three accounts of comparison classes are compared and evaluated. The first proposes that such classes serve as an argument to a function that determines a standard of comparison. The second maintains (...) that these classes restrict the domain of a measure function used to map entities to degrees. The third proposes that these classes limit the kind of individuals that participate in a binary relation; this relation is then used in the construction of a scale and a measure function. It is this third account that is most consistent with the empirical data. It can explain how comparison classes fix a standard of comparison, induce presuppositions concerning the comparative subjects, and induce incommensurability in comparative constructions. (shrink)

“Functional homology” appears regularly in different areas of biological research and yet it is apparently a contradiction in terms—homology concerns identity of structure regardless of form and function. I argue that despite this conceptual tension there is a legitimate conception of ‘homology of function’, which can be recovered by utilizing a distinction from pre-Darwinian physiology (use versus activity) to identify an appropriate meaning of ‘function’. This account is directly applicable to molecular developmental biology and shares a connection to the theme (...) of hierarchy in homology. I situate ‘homology of function’ within existing definitions and criteria for structural assessments of homology, and introduce a criterion of ‘organization’ for judging function homologues, which focuses on hierarchically interconnected interdependencies (similar to relative position and connection for skeletal elements in structural homology). This analysis of biological concepts has at least three broad philosophical consequences: (1) it provides the grounds for the study of behavior and psychological categories as homologues; (2) it demonstrates that philosophers who take selected effect function as primary effectively ignore large portions of comparative, structural, and experimental research, thereby misconstruing biological reasoning and knowledge; and, (3) it underwrites causal generalizations, which illuminates inferences made from model organisms in experimental biology.

The goal of this paper is to encourage a reconfiguration of the discussion about typology in biology away from the metaphysics of essentialism and toward the epistemology of classifying natural phenomena for the purposes of empirical inquiry. First, I briefly review arguments concerning ‘typological thinking’, essentialism, species, and natural kinds, highlighting their predominantly metaphysical nature. Second, I use a distinction between the aims, strategies, and tactics of science to suggest how a shift from metaphysics to epistemology might be accomplished. Typological (...) thinking can be understood as a scientific tactic that involves representing natural phenomena using idealizations and approximations, which facilitates explanation, investigation, and theorizing via abstraction and generalization. Third, a variety of typologies from different areas of biology are introduced to emphasize the diversity of this representational reasoning. One particular example is used to examine how there can be epistemological conflict between typology and evolutionary analysis. This demonstrates that alternative strategies of typological thinking arise due to the divergent explanatory goals of researchers working in different disciplines with disparate methodologies. I conclude with several research questions that emerge from an epistemological reconfiguration of typology. (shrink)

One foundational question in contemporarybiology is how to `rejoin evolution anddevelopment. The emerging research program(evolutionary developmental biology or`evo-devo) requires a meshing of disciplines,concepts, and explanations that have beendeveloped largely in independence over the pastcentury. In the attempt to comprehend thepresent separation between evolution anddevelopment much attention has been paid to thesplit between genetics and embryology in theearly part of the 20th century with itscodification in the exclusion of embryologyfrom the Modern Synthesis. This encourages acharacterization of evolutionary developmentalbiology as the marriage (...) of evolutionary theoryand embryology via developmental genetics. Butthere remains a largely untold story about thesignificance of morphology and comparativeanatomy (also minimized in the ModernSynthesis). Functional and evolutionarymorphology are critical for understanding thedevelopment of a concept central toevolutionary developmental biology,evolutionary innovation. Highlighting thediscipline of morphology and the concepts ofinnovation and novelty provides an alternativeway of conceptualizing the `evo and the `devoto be synthesized. (shrink)

The paper explains what disjunctivism is and explores its implications for skepticism. Following an account of Paul Snowdon’s conception of a disjunctivist account of perceptual experience the the focus is on how disjunctivism has figured in the epistemological work of John McDowell. A conception of recognitional abilities is deployed to expand on McDowell’s position. Finally, there is consideration of whether McDowell offers a satisfactory response to skepticism, taking account of criticism’s made by Crispin Wright.

The prospect for widespread therapeutic use of human fetal tissues has aroused strong emotions and prompted several objections. Fetal tissue transplantation circumscribed by medical and moral limits will not erode important ethical values, but the pace of scientific research must not preempt public debate and a verdict consistent with societal values.

Alan Bailey offers a clear and vigorous exposition and defence of the philosophy of Sextus Empiricus, one of the most influential of ancient thinkers, the father of philosophical scepticism. The subsequent sceptical tradition in philosophy has not done justice to Sextus: his views stand up today as remarkably insightful, offering a fruitful way to approach issues of knowledge, understanding, belief, and rationality. Bailey's refreshing presentation of Sextus to a modern philosophical readership rescues scepticism from the sceptics.

First published in 1967, _Writing and Difference_, a collection of Jacques Derrida's essays written between 1959 and 1966, has become a landmark of contemporary French thought. In it we find Derrida at work on his systematic deconstruction of Western metaphysics. The book's first half, which includes the celebrated essay on Descartes and Foucault, shows the development of Derrida's method of deconstruction. In these essays, Derrida demonstrates the traditional nature of some purportedly nontraditional currents of modern thought—one of his main targets (...) being the way in which "structuralism" unwittingly repeats metaphysical concepts in its use of linguistic models. The second half of the book contains some of Derrida's most compelling analyses of why and how metaphysical thinking must exclude writing from its conception of language, finally showing metaphysics to be constituted by this exclusion. These essays on Artaud, Freud, Bataille, Hegel, and Lévi-Strauss have served as introductions to Derrida's notions of writing and _différence_—the untranslatable formulation of a nonmetaphysical "concept" that does not exclude writing—for almost a generation of students of literature, philosophy, and psychoanalysis. _Writing and Difference_ reveals the unacknowledged program that makes thought itself possible. In analyzing the contradictions inherent in this program, Derrida foes on to develop new ways of thinking, reading, and writing,—new ways based on the most complete and rigorous understanding of the old ways. Scholars and students from all disciplines will find _Writing and Difference_ an excellent introduction to perhaps the most challenging of contemporary French thinkers—challenging because Derrida questions thought as we know it.

The desire to minimize the number of individual new entities postulated is often referred to as quantitative parsimony. Its influence on the default hypotheses formulated by scientists seems undeniable. I argue that there is a wide class of cases for which the preference for quantitatively parsimonious hypotheses is demonstrably rational. The justification, in a nutshell, is that such hypotheses have greater explanatory power than less parsimonious alternatives. My analysis is restricted to a class of cases I shall refer to as (...) additive. Such cases involve the postulation of a collection of qualitatively identical individual objects which collectively explain some particular observed phenomenon. Especially clear examples of this sort occur in particle physics.1Introduction2Particle physics: a case study3Three kinds of simplicity4Explanatory power5Explanation and non‐observation6Parsimony and scientific methodology7Conclusions.

The integration of technology in care is core business in nursing and this role requires that we must understand and use technology informed by evidence that goes much deeper and broader than actions and behaviours. We need to delve more deeply into its complexity because there is nothing minor or insignificant about technology as a major influence in healthcare outcomes and experiences. Evidence is needed that addresses technology and nursing from perspectives that examine the effects of technology, especially related to (...) increasing demands for efficiency, the relationship of technology to nursing and caring, and a range of philosophical questions associated with empowering people in their healthcare choices. Specifically, there is a need to confront in practice the ways technique influences care. Technique is the creation of a kind of thinking that is necessary for contemporary healthcare technology to develop and be applied in an efficient and rational manner. Technique is not an entity or specific thing, but rather a way of thinking that seeks to shape and organize nursing activity, and manage efficiently individual difference(s) in care. It emphasizes predetermined causal relationships, conformity, and sameness of product, process, and thought. In response is needed a radical vision of nursing that attempts in a real sense to ensure we meet the needs of individuals and their community. Activism and advocacy are needed, and a willingness to create a certain detachment from the imperatives that technique demands. It is argued that our responsibility as nurses is to respond in practice to the errors, advantages, difficulties, and temptations of technology for the benefit of those who most need our assistance and care.
