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)

Whose Keeper? is a profound and creative treatise on modernity and its challenge to social science. Alan Wolfe argues that modern liberal democracies, such as the United States and Scandinavia, have broken with traditional sources of mortality and instead have relied upon economic and political frameworks to define their obligations to one another. Wolfe calls for reinvigorating a sense of community and thus a sense of obligation to the larger society.

Rowlands defends environmentalism, that is, the conjunction of the ontological claim that cognitive processes are not located exclusively inside the skin of cognizing organisms and the epistemological claim that it is not possible to understand the nature of cognitive processes by focusing exclusively on what is occurring inside the skin of cognizing organisms. Chapter 3 is devoted to explaining how environmentalism differs from other forms of externalism about the mental. The crucial points are that the arguments to be presented for (...) the ontological claim do not turn on considerations about the content of mental states, that environmentalism implies a strong form of externalism, and that standard arguments for externalism, based on considerations about content, do not establish the strong form.

There is a tendency in current philosophical thought to treat sensory experiences as a peculiar species of propositional attitude. Alan Millar argues against this view. While allowing that experiences may in some sense bear propositional content, he presents a view of sensory experiences asa species of psychological state. He applies the resulting analytical framework to a discussion of justified belief, dealing, firstly, with how beliefs may derive justification from other beliefs, and secondly, with how current sensory experiences may contribute (...) to the justification of a person'sbeliefs. A key theme in his general approach is that justified belief results from the competent exercise of conceptual capacities, some of which involve an ability to respond appropriately to current experience. In working out this approach the author develops a view of concepts and theirmastery, explores the role of groundless beliefs drawing on suggestions of Wittgenstein, illuminates aspects of the thought of Locke, Hume, Quine, and Goldman, and finally offers a response to a sophisticated variety of scepticism.

There is a traditional conception of sensory experience on which the experiences one has looking at, say, a cat could be had by someone merely hallucinating a cat. Disjunctivists take issue with this conception on the grounds that it does not enable us to understand how perceptual knowledge is possible. In particular, they think, it does not explain how it can be that experiences gained in perception enable us to be in ‘cognitive contact’ with objects and facts. I develop this (...) chal- lenge to the traditional conception and then show that it is possible to accommo- date an adequate account of cognitive contact in keeping with the traditional conception. One upshot of the discussion is that experiences do not bear the explanatory burden placed upon them by disjunctivists. (shrink)

Illness creates a range of negative emotions in patients including anxiety, fear, powerlessness, and vulnerability. There is much debate on the ‘therapeutic’ or ‘helping’ nurse–patient relationship. However, despite the current agenda regarding patient-centred care, the literature concerning the development of good interpersonal responses and the view that a satisfactory nursing ethics should focus on persons and character traits rather than actions, nursing ethics is dominated by the traditional obligation, act-centred theories such as consequentialism and deontology. I critically examine these theories (...) and the role of duty-based notions in both general ethics and nursing practice. Because of well-established flaws, I conclude that obligation-based moral theories are incomplete and inadequate for nursing practice. I examine the work of Hursthouse on virtue ethics’ action guidance and the v-rules. I argue that the moral virtues and a strong (action-guiding) version of virtue ethics provide a plausible and viable alternative for nursing practice. I develop an account of a virtue-based helping relationship and a virtue-based approach to nursing. The latter is characterized by three features: (1) exercising the moral virtues such as compassion; (2) using judgement; and (3) using moral wisdom, understood to include at least moral perception, moral sensitivity, and moral imagination. Merits and problems of the virtue-based approach are examined. I relate the work of MacIntyre to nursing and I conceive nursing as a practice: nurses who exercise the virtues and seek the internal goods help to sustain the practice of nursing and thus prevent the marginalization of the virtues. The strong practice-based version of virtue ethics proposed is context-dependent, particularist, and relational. Several areas for future philosophical inquiry and empirical nursing research are suggested to develop this account yet further. (shrink)

How does the human animal who thinks and loves relate to criminal justice? This essay takes up the idea of a moral psychology of guilt promoted by Bernard Williams and Herbert Morris. Against modern liberal society’s ‘peculiar’ legal morality of voluntary responsibility, it pursues Morris’s ethical account of guilt as involving atonement and identification with others. Thinking of guilt in line with Morris, and linking it with the idea of moral psychology, takes the essay to Freud’s metapsychology in Civilization and (...) Its Discontents. Two conflicting routes to guilt are noted in Freud, one involving internalisation of external anger to suppress destructive instincts, the other loving identification with others in the process of self-formation. This second route is developed through the psychoanalytic thought of Hans Loewald and Jonathan Lear. Following Loewald, the moral psychology of self-formation makes loving identification with others the root of responsibility, guilt and atonement. Following Lear, the moral psychology of guilt developed on these lines renders psychoanalysis part of a broadly understood philosophical project following Aristotelian and Socratic principles. Underlying Morris’s account of guilt is the possibility of ‘prospective identification’, understood as the moral and psychological ground of guilt and reconciliation. This is the rational core of criminal justice, which maintains an uneasy relationship with law’s ‘peculiar’ morality. (shrink)

This volume explores questions about conceptual change from both scientific and philosophical viewpoints by analyzing the recent history of evolutionary developmental biology. It features revised papers that originated from the workshop "Conceptual Change in Biological Science: Evolutionary Developmental Biology, 1981-2011" held at the Max Planck Institute for the History of Science in Berlin in July 2010. The Preface has been written by Ron Amundson. In these papers, philosophers and biologists compare and contrast key concepts in evolutionary developmental biology and their (...) development since the original, seminal Dahlem conference on evolution and development held in Berlin in 1981. Many of the original scientific participants from the 1981 conference are also contributors to this new volume and, in conjunction with other expert biologists and philosophers specializing on these topics, provide an authoritative, comprehensive view on the subject. Taken together, the papers supply novel perspectives on how and why the conceptual landscape has shifted and stabilized in particular ways, yielding insights into the dynamic epistemic changes that have occurred over the past three decades. This volume will appeal to philosophers of biology studying conceptual change, evolutionary developmental biologists focused on comprehending the genesis of their field and evaluating its future directions, and historians of biology examining this period when the intersection of evolution and development rose again to prominence in biological science.

Causal relations among components and activities are intentionally misrepresented in mechanistic explanations found routinely across the life sciences. Since several mechanists explicitly advocate accurately representing factors that make a difference to the outcome, these idealizations conflict with the stated rationale for mechanistic explanation. We argue that these idealizations signal an overlooked feature of reasoning in molecular and cell biology—mechanistic explanations do not occur in isolation—and suggest that explanatory practices within the mechanistic tradition share commonalities with model-based approaches prevalent in population (...) biology.

Although natural philosophers have long been interested in individuality, it has been of interest to contemporary philosophers of biology because of its role in different aspects of evolutionary biology. These debates include whether species are individuals or classes, what counts as a unit of selection, and how transitions in individuality occur evolutionarily. Philosophical analyses are often conducted in terms of metaphysics (“what is an individual?”), rather than epistemology (“how can and do researchers conceptualize individuals so as to address some of (...) their scientific goals?”). We review several philosophical distinctions in order to shift attention from metaphysics to epistemology. Many controversies involve epistemological differences rather than metaphysical disagreement. This implies that a pluralist stance about individuality in biology is warranted and has metaphysical consequences because the pluralism emerges from the diversity of scientific interests that investigate the complexity of living phenomena.

This essay examines logical empiricism and American pragmatism, arguing that American philosophy's embrace of logical empiricism in the 1930s was not a turning away from Dewey's pragmatism. It places both movements within scientific philosophy and finds two key points on which they agreed: their revolutionary ambitions and their social engineering sensibility. The essay suggests that the disagreement over emotivism in ethics should be placed within the context of a larger issue on which the movements disagreed: demarcationism and imperialism.

Human rights are rights which all persons equally have simply insofar as they are human. But are there any such rights? How, if at all, do we know that there are? It is with this question of knowledge, and the related question of existence, that I want to deal in this paper. 1. CONCEPTUAL QUESTIONS The attempt to answer each of these questions, however, at once raises further, more directly conceptual questions. In what sense may human rights be said to (...) exist? What does it mean to say that there are such rights or that persons have them? This question, in turn, raises a question about the nature of human rights. What is the meaning of the expression “human rights”? Within the limits of the present paper I cannot hope to deal adequately with the controversial issues raised by these conceptual questions. But we may make at least a relevant beginning by noting that, in terms of Hohfeld's famous classification of four different kinds of rights, the human rights are primarily claim-rights, in that they entail correlative duties of other persons or groups to act or to refrain from acting in ways required for the right-holders' having that to which they have rights. It will help our understanding of this and other aspects of human rights if we note that the full structure of a claim-right is given by the following formula: A has a right to X against B by virtue of Y. There are five main elements here: first, the Subject of the right, the person or persons who have the right; second, the Nature of the right; third, the Object of the right, what it is a right to; fourth, the Respondent of the right, the person or persons who have the correlative duty; fifth, the Justifying Basis or Ground of the right.

The Routledge Handbook of Mechanisms and Mechanical Philosophy is an outstanding reference source to the key topics, problems, and debates in this exciting subject and is the first collection of its kind. Comprising over thirty chapters by a team of international contributors, the Handbook is divided into four Parts: Historical perspectives on mechanisms The nature of mechanisms Mechanisms and the philosophy of science Disciplinary perspectives on mechanisms. Within these Parts central topics and problems are examined, including the rise of mechanical (...) philosophy in the seventeenth century; what mechanisms are made of and how they are organized; mechanisms and laws and regularities; how mechanisms are discovered and explained; dynamical systems theory; and disciplinary perspectives from physics, chemistry, biology, biomedicine, ecology, neuroscience, and the social sciences. Essential reading for students and researchers in philosophy of science, the Handbook will also be of interest to those in related fields, such as metaphysics, philosophy of psychology, and history of science.

This article outlines a conception of perceptual-recognitional abilities. These include abilities to recognize certain things from their appearance to some sensory modality, as being of some kind, or as possessing some property. An assumption of the article is that these abilities are crucial for an adequate understanding of perceptual knowledge. The specific aim here is to contrast those abilities with abilities or competences as conceived in the virtue-theoretic literature, with particular reference to views of Ernest Sosa and John Greco. In (...) the course of the discussion, it is emphasized that the notion of exercising a perceptual-recognitional ability is a success notion: exercising such an ability is nothing less than acquiring knowledge. Even so, the view can make sense of our fallibility. It can also be defended in the face of an objection stemming from consideration of what are here called success-rate abilities. (shrink)

The idea that moral virtues form some sort of “unity” has received considerable attention from virtue theorists. In this paper, I argue that the possibility of unity among intellectual virtues has been wrongly overlooked. My approach has two main components. First, I work to distinguish the variety of different views that are available under the description of a unity thesis. I suggest that these views can be categorised depending on whether they are versions of standard unity or of strong unity. (...) Standard unity claims that the possession of one virtue implies possession of all the others. Strong unity claims that the virtues are, in some sense, all the same thing. By exploring what these different versions of unity would look like when applied to intellectual virtues, I aim to provide a menu of options for future work in virtue epistemology. I then develop and defend one of these options in more detail, arguing that the initially less plausible strong unity has merit when applied to the intellectual sphere. In these two ways, I aim to show that the possibility of unity among the intellectual virtues is deserving of serious consideration. (shrink)

Model organisms are central to contemporary biology and studies of embryogenesis in particular. Biologists utilize only a small number of species to experimentally elucidate the phenomena and mechanisms of development. Critics have questioned whether these experimental models are good representatives of their targets because of the inherent biases involved in their selection (e.g., rapid development and short generation time). A standard response is that the manipulative molecular techniques available for experimental analysis mitigate, if not counterbalance, this concern. But the most (...) powerful investigative techniques and molecular methods are applicable to single-celled organisms (‘microbes’). Why not use unicellular rather than multicellular model organisms, which are the standard for developmental biology? To claim that microbes are not good representatives takes us back to the original criticism leveled against model organisms. Using empirical case studies of microbes modeling ontogeny, we break out of this circle of reasoning by showing: (a) that the criterion of representation is more complex than earlier discussions have emphasized; and, (b) that different aspects of manipulability are comparable in importance to representation when deciding if a model organism is a good model. These aspects of manipulability harbor the prospect of enhancing representation. The result is a better understanding of how developmental biologists conceptualize research using experimental models and suggestions for underappreciated avenues of inquiry using microbes. More generally, it demonstrates how the practical aspects of experimental biology must be scrutinized in order to understand the associated scientific reasoning. (shrink)

This paper draws upon a research study of accountants and HR specialists. The study eschewed hypothetical scenarios and focused upon those situations and scenarios that the interviewees defined as causing them ethical concerns. There are two distinct but related issues arising from the paper. The first is that the singular categorisations of moral reasoning attributed to individuals when faced with hypothetical scenarios by many who write on the issue of moral reasoning, did not correspond to the fluidity in moral choices (...) faced by the interviewees as they experienced their unfolding moral dilemmas. The second issue relates to the unwillingness of the interviewees to give voice to their concerns, not only externally, but also within their employing organisations. The tensions within the two cases featured were held in check only by the diminution of the autonomy of the two principal actors. As a consequence, the exercise of moral agency was denied. (shrink)

The ubiquity of top-down causal explanations within and across the sciences is prima facie evidence for the existence of top-down causation. Much debate has been focused on whether top-down causation is coherent or in conflict with reductionism. Less attention has been given to the question of whether these representations of hierarchical relations pick out a single, common hierarchy. A negative answer to this question undermines a commonplace view that the world is divided into stratified ‘levels’ of organization and suggests that (...) attributions of causal responsibility in different hierarchical representations may not have a meaningful basis for comparison. Representations used in top-down and bottom-up explanations are primarily ‘local’ and tied to distinct domains of science, illustrated here by protein structure and folding. This locality suggests that no single metaphysical account of hierarchy for causal relations to obtain within emerges from the epistemology of scientific explanation. Instead, a pluralist perspective is recommended—many different kinds of top-down causation (explanation) can exist alongside many different kinds of bottom-up causation (explanation). Pluralism makes plausible why different senses of top-down causation can be coherent and not in conflict with reductionism, thereby illustrating a productive interface between philosophical analysis and scientific inquiry.

What do people consciously experience when they read? There has been almost no rigorous research on this question, and opinions diverge radically among both philosophers and psychologists. We describe three studies of the phenomenology of reading and its relationship to memory of textual detail and general cognitive abilities. We find three main results. First, there is substantial variability in reports about reading experience, both within and between participants. Second, reported reading experience varies with passage type: passages with dialogue prompted increased (...) reports of inner speech, while passages with vivid visual detail prompted increased reports of visual imagery. Third, reports of visual imagery experiences, inner speech experiences, and experiences of conscious visual perception of the words on the page were at best weakly related to general cognitive abilities and memory of visual and auditory details.

Idealization is a reasoning strategy that biologists use to describe, model and explain that purposefully departs from features known to be present in nature. Similar to other strategies of scientific reasoning, idealization combines distinctive strengths alongside of latent weaknesses. The study of ontogeny in model organisms is usually executed by establishing a set of normal stages for embryonic development, which enables researchers in different laboratory contexts to have standardized comparisons of experimental results. Normal stages are a form of idealization because (...) they intentionally ignore known variation in development, including variation associated with phenotypic plasticity (e.g. via strict control of environmental variables). This is a tension between the phenomenon of plasticity and the practice of staging that has consequences for evolutionary developmental investigation because variation is conceptually removed as a part of rendering model organisms experimentally tractable. Two compensatory tactics for mitigating these consequences are discussed: employing a diversity of model organisms and adopting alternative periodizations. (shrink)

A central reason that undergirds the significance of evo-devo is the claim that development was left out of the Modern synthesis. This claim turns out to be quite complicated, both in terms of whether development was genuinely excluded and how to understand the different kinds of embryological research that might have contributed. The present paper reevaluates this central claim by focusing on the practice of model organism choice. Through a survey of examples utilized in the literature of the Modern synthesis, (...) I identify a previously overlooked feature: exclusion of research on marine invertebrates. Understanding the import of this pattern requires interpreting it in terms of two epistemic values operating in biological research: theoretical generality and explanatory completeness. In tandem, these values clarify and enhance the significance of this exclusion. The absence of marine invertebrates implied both a lack of generality in the resulting theory and a lack of completeness with respect to particular evolutionary problems, such as evolvability and the origin of novelty. These problems were salient to embryological researchers aware of the variation and diversity of larval forms in marine invertebrates. In closing, I apply this analysis to model organism choice in evo-devo and discuss its relevance for an extended evolutionary synthesis. (shrink)

Rationality and reasonableness are often sharply distinguished from one another and are even held to be in conflict. On this construal, rationality consists in means-end calculation of the most efficient means to one's ends, while reasonableness consists in equitableness whereby one respects the rights of other persons as well as oneself. To deal with this conflict, it is noted that both rationality and reasonableness are based on reason, which is analyzed as the power of attaining truth, and especially necessary truth. (...) It is then shown that, by the rationality involved in reason, the moral principle of reasonableness, the Principle of Generic Consistency, has a stringently rational justification in that to deny or violate it is to incur self-contradiction. Objections are considered bearing on relevance and motivation. It is concluded that, where reasonableness and egoistic rationality conflict, the former is rationally superior. (shrink)

Descartes's general rule that “whatever is clearly and distinctly perceived is true” has traditionally been criticized on two closely related grounds. As Leibniz, for example, puts it, clearness and distinctness are of no value as criteria of truth unless we have criteria of clearness and distinctness; but Descartes gives none. And consequently, the standards of judgment which the rule in fact evokes are purely subjective and psychological. There must hence be set up analytic, logical “marks” by means of which it (...) can infallibly and without arbitrariness be recognized whether any ideas or propositions are or are not clear and distinct.

Social screening of investments calls not only for investment policy and criteria, but also for information about companies, their policies, practices and performance. The Global Reporting Initiative (GRI) and its June 2000 Sustainability Reporting Guidelines have the potential to significantly improve the usefulness and quality of information reported by companies about their environmental, social and economic impacts and performance. The GRI aims to develop a voluntary reporting framework that will elevate sustainability reporting practices to a level equivalent to that of (...) financial reporting in rigour, comparability, auditability and general acceptance. This will be a welcome and efficient supplement to the questionnaires, interviews, press releases, media reports and other sources of information traditionally used for screening in investment decision making - social/ethical and mainstream. The Dow Jones Sustainability Group Index, the Jantzi Social Index and the Innovest EcoValue'21 analytical platform, together with the SRI community, are all likely to benefit from GRI-style sustainability reports. One of the GRI's key challenges is to accommodate the broad variety of disclosure needs and expectations of a wide range of report users and company stakeholders. To maximize the usefulness of the GRI Guidelines, report users, including the SRI community, need to be engaged in the process of developing and refining the Guidelines over time. The GRI Guidelines are emerging as an important instrument in enabling companies to communicate with their stakeholders about performance and accountability beyond just the financial bottom line.

In this paper I examine the interconnections between two paradigms of technology, nature, and social life, and their associated environmental impacts. The dominant technocratic philosophy which now guides policy and technological power is mechanistic. It conceptualizes nature as a resource to be controlled fully for human ends and it threatens drastically to alter the integrity of the planet’s ecosystems. Incontrast, the organic, person-planetary paradigm conceptualizes intrinsic value in all beings. Deep ecology gives priority to community and ecosystem integrity and seeks (...) to guide the design and applications of technology according to principles which follow from ecological understanding. I describe this shift in paradigms and how it affects our perceptions, values, and actions. (shrink)

Should a philosophical account of perceptual knowledge accord a justificatory role to sensory experiences? This discussion raises problems for an affirmative answer and sets out an alternative account on which justified belief is conceived as well-founded belief and well-foundedness is taken to depend on knowledge. A key part of the discussion draws on a conception of perceptual-recognitional abilities to account for how perception gives rise both to perceptual knowledge and to well-founded belief.

Robert Wilson’s The Eugenic Mind Project is a major achievement of engaged scholarship and socially relevant philosophy and history of science. It exemplifies the virtues of interdisciplinarity. As principal investigator of the Living Archives on Eugenics in Western Canada project, while employed in the Department of Philosophy at the University of Alberta, Wilson encountered a proverbial big ball of mud with questions and issues that involved local individuals living through a painful set of memories and implicated his institutional home in (...) outstanding moral obligations. It is engaged scholarship because it required building relationships with affected persons and taking responsibility for his institution’s legacy, as well as transforming Wilson’s own outlook along the way. It is socially relevant philosophy and history of science because it brings to light issues that remain salient today, especially how eugenic themes are ubiquitous in societal discourse and evinced in everyday decisions. It is interdisciplinary because to accomplish this type of analysis requires intellectual gymnastics that range over diverse domains of research: from standpoint theory and disability studies to oral history and governmental policy; from the evolutionary biology of prosociality and variation to conceptual questions about the categorization of human traits and types.
