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)

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)

Some philosophical accounts imply that masturbation is inferior sexual activity. Against this, Soble argues that masturbation is central. Relying on the physical-anatomical indistinguishability of sexual act-types, he derives a Zeno-style paradox about sexual activity: either all sexual activity (even ordinary coitus) is masturbatory or none of it is (not even solitary masturbation). Soble argues for the first horn of the dilemma, thus ensuring that solitary masturbation is a member of the continuum of sexual activities. Going beyond anatomy, Soble also argues (...) that the central psychological features of paired sexual activity are normally exhibited also by solitary masturbation, which further establishes that solitary masturbation is on the continuum of sexual activity. Altogether, Soble's arguments support a "unary" model of sexuality, compelling us to take seriously the genuine sexual nature of solitary masturbation, a result that is important for the philosophy of sex, the scientific study of sexuality, and the politics of human sexuality.

Robert Nozick argued that we would not plug into his machine that could give us any experiences we chose. More recently Richard Kraut has argued that it would be prudentially rational to plug into the machine, since only experiences count for personal welfare. I argue that both are wrong, that either choice can be rational or not, depending on the central desires of the subjects choosing. This claim is supported by the empirical evidence, which shows an almost even split between (...) those who would enter and those who would not. If we interpret those on both sides as making rational choices to maximize their personal well-being, and if such rational choice tends to enhance well-being, then the experience machine thought experiment supports neither experientialism nor its denial, but instead a rational desire satisfaction account of personal well-being. Unlike objective list and perfectionist accounts, the desire satisfaction account of well-being easily accommodates rational choices on both sides, depending on the motivational sets of the choosers.

Speech categories are defined by multiple acoustic dimensions and their boundaries are generally fuzzy and ambiguous in part because listeners often give differential weighting to these cue dimensions during phonetic categorization. This study explored how a listener's perception of a speaker's socio-indexical and personality characteristics influences the listener's perceptual cue weighting. In a matched-guise study, three groups of listeners classified a series of gender-neutral /b/-/p/ continua that vary in VOT and F0 at the onset of the following vowel. Listeners were (...) assigned to one of three prompt conditions and rated the talker in terms of vocal gender prototypicality, attractiveness, friendliness, confidence, trustworthiness, and gayness. Male listeners and listeners who saw a male face showed less reliance on VOT compared to listeners in the other conditions. Listeners' visual evaluation of the talker also affected their weighting of VOT and onset F0 cues, although the effects of facial impressions differ depending on the gender of the listener. The results demonstrate that individual differences in perceptual cue weighting are modulated by the listener's gender and his/her subjective evaluation of the talker. These findings lend support for exemplar-based models of speech perception and production where socio-indexical features are encoded as a part of the episodic traces in the listeners' mental lexicon. This study also shed light on the relationship between individual variation in cue weighting and community-level sound change by demonstrating that VOT and onset F0 co-variation in North American English has acquired a certain degree of socio-indexical significance.

Bridging the gap between the world of science and the realm of the spiritual, B. Alan Wallace introduces a natural theory of human consciousness that has its roots in contemporary physics and Buddhism. Wallace's "special theory of ontological relativity" suggests that mental phenomena are _conditioned_ by the brain, but do not _emerge_ from it. Rather, the entire natural world of mind and matter, subjects and objects, arises from a unitary dimension of reality that is more fundamental than these dualities, (...) as proposed by Wolfgang Pauli and Carl Jung. To test his hypothesis, Wallace employs the Buddhist meditative practice of _samatha_, refining one's attention and metacognition, to create a kind of telescope to examine the space of the mind. Drawing on the work of the physicist John Wheeler, he then proposes a more general theory in which the participatory nature of reality is envisioned as a self-excited circuit. In comparing these ideas to the Buddhist theory known as the Middle Way philosophy, Wallace explores further aspects of his "general theory of ontological relativity," which can be investigated by means of _vipasyana_, or insight, meditation. Wallace then focuses on the theme of symmetry in reference to quantum cosmology and the "problem of frozen time," relating these issues to the theory and practices of the Great Perfection school of Tibetan Buddhism. He concludes with a discussion of the general theme of complementarity as it relates to science and religion. The theories of relativity and quantum mechanics were major achievements in the physical sciences, and the theory of evolution has had an equally deep impact on the life sciences. However, rigorous scientific methods do not yet exist to observe mental phenomena, and naturalism has its limits for shedding light on the workings of the mind. A pioneer of modern consciousness research, Wallace offers a practical and revolutionary method for exploring the mind that combines the keenest insights of contemporary physicists and philosophers with the time-honored meditative traditions of Buddhism.

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.

The term 'episodic memory' refers to our memory for unique, personal experiences, that we can date at some point in our past - our first day at school, the day we got married. It has again become a topic of great importance and interest to psychologists, neuroscientists, and philosophers. How are such memories stored in the brain, why do certain memories disappear (especially those from early in childhood), what causes false memories (memories of events we erroneously believe have really taken (...) place)? Since Endel Tulving's classic book 'Episodic memory' (OUP, 1983) very few books have been published on this topic. In recent years however, many of the assumptions made about episodic memory have had to be reconsidered as a result of new techniques, which have allowed us a far deeper understanding of episodic memory. In 'Episodic memory: new directions in research' three of the worlds leading researchers in the topic of memory have brought together a stellar team of contributors from the fields of cognitive psychology, neuropsychology, and neuroscience, to present an account of what we now know about about this fundamentally important topic. The list of contributors includes, amongst others, Daniel Schacter, Richard Morris, Fareneh Vargha-Khadem, and Endel Tulving. The work presented within this book will have a profound effect on the direction that future research in this topic will take. (shrink)

The artform of standup comedy can be seen as having much in common with the discipline of philosophy, particularly with the way philosophy is carried out or “performed,” whether professionally or otherwise. There are, for instance, certain basic similarities between how standup comedians and philosophers value ideals of clarity and precision when it comes to the issue of determining what kind of language is best to employ if one seeks to either effectively deliver a funny joke, as in the case (...) of standup comedy, or if one seeks to effectively articulate and present an argument that can later be assessed as sound, as in the case of philosophy. The reason this is of note is because it is rooted in another similarity that serves not only to bring these two activities significantly closer but to isolate standup comedy from most artforms when it comes to how it conceives of matters pertaining to interpretation and purpose. More specifically, this is the fact that standup comedians and philosophers alike hope, and even expect on some level, that, in the best of cases, their respective jokes and reasoned arguments will compel some form of unanimous approval from those who properly understand and engage with their content. When this observation is combined with the additional observation that jokes can also serve as vehicles for imparting wisdom of a genuinely philosophical nature despite the fact that generating laughter rather than seeking truth per se represents standup comedy’s ostensive primary goal, this leads one to wonder how porous the boundaries that otherwise serve to distinguish these two activities might be. In particular, in light of the nature and scope of the many similarities that can be said to exist between them, which I lay out and discuss in the article, it seems that standup comedy could even be reasonably argued to be the artform closest to philosophy.

At some time around 200 A.D., the Stoic philosopher and teacher Cleomedes delivered a set of lectures on elementary astronomy as part of a complete introduction to Stoicism for his students. The result was _The Heavens, _the only work by a professional Stoic teacher to survive intact from the first two centuries A.D., and a rare example of the interaction between science and philosophy in late antiquity. This volume contains a clear and idiomatic English translation—the first ever—of _The Heavens, _along (...) with an informative introduction, detailed notes, and technical diagrams. This important work will now be accessible to specialists in both ancient philosophy and science and to readers interested in the history of astronomy and cosmology but with no knowledge of ancient Greek.

To an unusual extent, philosophers agree that counterfactuals have truth conditions involving the most similar possible worlds where their antecedents are true, in the style of the celebrated and path‐breaking Stalnaker/Lewis accounts. Roughly, these accounts say that the counterfactual if A were the case, C would be the case is true if and only if at the most similar A‐worlds, C is true. I will argue that there are general structural problems with the appeals to both “the most” and “similar”. (...) I will challenge any fixation on ‘the most __ worlds’, however we fill in the blank with a non‐trivial ordering of worlds: in ignoring worlds that are later in the ordering, it adjudicates various implausibly specific counterfactuals to be true. I will then raise foundational problems for appealing to ‘similarity’—from consequents that are chancy, disjunctive antecedents, and unspecific antecedents more generally. I will also raise further problems for a number of specific proposals for understanding ‘similarity’. A recurring theme will be the tension that may arise between probability and similarity considerations. I will end by arguing for a paradigm shift, replacing ‘the most similar worlds’ approach with one based on conditional chances. (shrink)

Then (t, F) is closed in r-Dagger under truth-Functions and relevant implication, Which, When confined to (t, F) acts just like material 'implication.' but r-Dagger admits of many propositions other than t, F. The article also contains polemics against extensionalism and nominalism. (edited).

In Wollstonecraft’s early writings, she articulates the foundational theological and philosophical principles that would underpin her work throughout her career. One difference between her early and later work lies in the way that the values to which she refers are combined. Whereas Wollstonecraft at first appeals to the separate ideals of independence, equality, and virtue, from the 1790s onwards she integrates these into a characteristic republican framework that was in common use amongst dissenting theorists at the time. The set of (...) values on which Wollstonecraft draws, and the version of the republican framework that she develops, closely resemble those of Richard Price with whose work she was familiar. Examining the structural similarities between their respective models, I argue, gives us an insight into the systematic manner of aspects of Wollstonecraft’s own thought. It also allows us to see how Wollstonecraft goes beyond the republicanism of Price and others as she develops her own feminist solutions to the problems of structural domination. (shrink)

Defenders of the enhanced indispensability argument argue that the most effective route to platonism is via the explanatory role of mathematical posits in science. Various compelling cases of mathematical explanation in science have been proposed, but a satisfactory general philosophical account of such explanations is lacking. In this paper, I lay out the framework for such an account based on the notion of “the mathematical stance.” This is developed by analogy with Dennett’s well-known concept of “the intentional stance.” Roughly, adopting (...) the mathematical stance towards a particular physical phenomenon involves treating it as an abstract mathematical structure for the purposes of prediction and explanation. Interestingly, Dennett himself frequently draws analogies between his intentional stance towards beliefs and desires and scientists’ stance towards centers of gravity. I explore the theoretical role played by centers of gravity within science and discuss how an indispensabilist platonist ought to categorize the ontological status of this type of posit. I conclude with some thoughts on how an approach based on the mathematical stance might be developed into a more general philosophical account of the application of mathematics in science. (shrink)

Expressions like "two novels" are traditionally taken to convey information about cardinality and are analyzed using a cardinality function. Salmon (Philosop Perspect 11:1–15, 1997), Liebesman (Australasian J Philos 93:21–42, 2015; Philos’ Impr 16:1–25, 2016; In D. W. Zimmerman (ed.), Oxford studies in metaphysics, Oxford University Press, Oxford, forthcoming), and Haida and Trinh (in: Dočekal, Wagiel (eds) Formal approaches to number in Slavic and beyond, Language Science Press, Berlin, 2001) argue against this traditional account, claiming that it can’t explain our use (...) of expressions like "two and a half novels". According to them, the proper analysis of such expressions requires a partiality measure, which maps entities to rational numbers such as 2.5. In this paper, we set out to defend the traditional account. To do so, we demonstrate that an analysis based on a partiality measure is inconsistent with the truth conditions of plural comparatives and equatives. We also show that such an account doesn’t provide an adequate analysis for expressions like "two novels and a half", nor for their French counterparts (e.g., "deux romans et demi"). Critically, such expressions contain no constituent that could refer to the number 2.5. We provide an alternative analysis for all these expressions, based on cardinality and an operation of non-overlapping summation. (shrink)

The paper is a response to William Newman’s rebuttal of a critique of his account of the origins of modern chemistry by Alan Chalmers.

Texts from the writings of Boyle that are cited by Newman as (...) posing problems for Chalmers’ thesis are interpreted as in fact supporting it. (shrink)

This paper looks at some of the ways in which environmental philosophers have sought to press ecological concepts into the service of environmental ethics. It seeks to show that although ecology plays a major role in opening our eyes to sources of value in the natural world, we should not necessarily attempt to build our account of nature’s value upon the concepts which ecology supplies. No description is going to capture nature’s essence; no formula is going to demonstrate its value. (...) We should recognise the natural world as a particular historic individual and relate to it accordingly. This means acknowledging its value in a contingent, conditional and provisional way, and recognizing its value as a precondition of the value of our own lives. (shrink)

This essay looks at some of the key aspects of Hans Reichenbach’s career as a radio engineer, broadcaster, and producer. It argues that some of the themes of Reichenbach’s logical empiricism can be illuminated by looking at them in relation to his work as a radio engineer during and after World War One. It also argues that attention to the educational activities he undertook in the new broadcast radio medium can help us understand that affinities he saw between logical empiricism (...) and other modernizing projects of Weimar Germany.

Much specific support for theories of personal identity comes from data which is really about 'what matters' in identity. I argue that if we accept Parfit's arguments that identity is not sufficient for what matters, then we should think our subject matter is actually underdetermined and indefinite, and there can be no correct answer to the question 'Under what conditions is P2 identical to P!?'.

Jewish by birth, though from a secular family, Alan Morinis took a deep journey into Hinduism and Buddhism as a young man. He received a doctorate for his study of Hindu pilgrimage, learned yoga in India with B. K. S. Iyengar, and attended his first Buddhist meditation course in the Himalayas in 1974. But in 1997, when his film career went off track and he reached for some spiritual oxygen, he felt inspired to explore his Jewish heritage. In his (...) reading he happened upon a Jewish tradition of spiritual practice called Mussar. Gradually he realized he had stumbled on an insightful discipline for self-development, complete with meditative, contemplative, and other well-developed transformative practices designed to penetrate the deepest roots of the inner life. Eventually reaching the limits of what he could learn on his own, he decided to seek out a Mussar teacher. That was not easily achieved, since almost the entire world of the Mussar tradition had been wiped out in the Holocaust. In time, he did find an accomplished master who stood in an unbroken line of transmission of the Mussar tradition, and who lived at the center of a community of Orthodox Jews on Long Island. This book tells the story of Morinis’s journey to meet his teacher and what he learned from him, and reveals the central teachings and practices that are the spiritual treasury and legacy of Mussar. Alan Morinis has written this book because the wisdom and practices that helped him so much have not penetrated the world beyond the confines of Orthodox Judaism, and may not be fully appreciated even there at this time. His hope is that Jews and non-Jews alike will find in Mussar a time-tested path of spiritual practice that will help them discover the hidden radiance within. (shrink)

Let φ be a monadic second order sentence about a finite structure from a class K which is closed under disjoint unions and has components. Compton has conjectured that if the number of n element structures has appropriate asymptotics, then unlabelled (labelled) asymptotic probabilities ν(φ) (μ(φ) respectively) for φ always exist. By applying generating series methods to count finite models, and a tailor made Tauberian lemma, this conjecture is proved under a mild additional condition on the asymptotics of the number (...) of single component K-structures. Prominent among examples covered, are structures consisting of a single unary function (or partial function) and a fixed number of unary predicates. (shrink)

Pluractionality (PLR) is the morphological category that generally signifies multiple actions. This paper, based on original fieldwork, provides the first investigation of PLR in Chechen, a Nakh language spoken in the eastern central part of the North Caucasus. The data reflects the standard dialect of Chechen spoken in and near the cities of Murus-Martan and Grozny. Chechen PLR, which is marked by stem vowel alternations, prototypically signifies the repetition of an event (e.g., saca/sieca `to stop once/many times'; laaca/liica `to catch (...) once/many times'). The plurality of the nominative argument can affect the interpretation of some verbs (e.g., ghitta `to wake up'; hitta `to assume a standing position'), rendering the reading distributive. More interestingly, a durative reading, signaling the prolongation of an event, is available for some verbs (e.g., xouzha/xiizha `to ache momentarily/for a while', zouza/ziiza `to itch momentarily/for a while') but not others. Following Ojeda (1998) and Lasersohn (1995), PLR is accounted for in terms of the pluralization of the event argument of a predicate. The various semantic effects are the results of interactions between the aspectual properties of individual verbs and event pluralization. (shrink)

Intentionalism must be distinguished from computational psychology. The former is a mentalist-realist metatheoretical stance vis-a-vis the latter, which is a research programme devoted to the construction of informationally-characterized simulation models for human behavior, perception, cognition, etc. Intentionalism has its attractive aspects, but unfortunately it is plagued by severe conceptual difficulties. Recent attempts to justify the intentionalist interpretation of computational models, by J.A. Fodor and by C. Graves, J.J. Katz et al., fail to secure a conceptually adequate and genuinely intentional sense (...) for the intentional idiom they employ. (shrink)

The views on race expressed by Hume in a footnote appended to his essay ‘Of National Characters’ seem so egregiously misguided that the suspicion has developed among some commentators that his fundamental philosophical outlook may be inextricably intertwined with a host of deeply pejorative racist assumptions that serve to encourage a pervasive pattern of exploitative and oppressive actions directed against people of colour. This paper, in contrast, argues that predominant thrust of Hume’s account of human nature is towards emphasizing the (...) psychological similarities manifest by all healthy human beings, irrespective of biological sex or alleged racial affiliations: from Hume’s perspective, white Europeans and people of colour are separated by much less than they have in common. It is, moreover, Hume’s acknowledgement of the characteristics that all human beings have in common that motivates his forceful criticisms of the practice of chattel slavery. Basing his judgement on his appreciation of our shared humanity, Hume condemns slavery as a practice that cannot be reconciled with any legitimate set of moral sentiments. (shrink)
