Engineers today cannot meet their professional obligation to the welfare of society if they do not have a broad, multidisciplinary vision, and yet a multidisciplinary vision is becoming enormously difficult to obtain. A new curriculum must emerge that can integrate a focused, discipline-based scientific approach with an integrated approach. To do this, we must recognize that there is already a structure that is deeply embedded into the current pedagogy, which values performance ratios such as efficiency as paramount. Current trends indicate (...) a call for a broader, reflexive, and preventative curriculum, but like many other calls for change, these will fail if the focus continues to be on wrong values. A model for an adaptive engineering curriculum is developed that strives to maintain a scientific approach as well as a broad “culture-based approach.” A new way of thinking about engineering curriculum must involve a “resymbolization” in which experience, context, community, and certain nonmeasurable principles are valued.

Consider a circle and a pair of its semicircles. Which is prior, the whole or its parts? Are the semicircles dependent abstractions from their whole, or is the circle a derivative construction from its parts? Now in place of the circle consider the entire cosmos (the ultimate concrete whole), and in place of the pair of semicircles consider the myriad particles (the ultimate concrete parts). Which if either is ultimately prior, the one ultimate whole or its many ultimate parts?

Originally published in 1982, this was an extensive and up-to-date review of research into the psychology of deductive reasoning, Jonathan Evans presents an alternative theoretical framework to the rationalist approach which had dominated much of the published work in this field at the time. The review falls into three sections. The first is concerned with elementary reasoning tasks, in which response latency is the prime measure of interest. The second and third sections are concerned with syllogistic and propositional reasoning (...) respectively, in which interest has focused on the explanation of frequently observed logical errors. In an extended discussion it is argued that reasoning processes are content specific, and give little indication of the operation of any underlying system of logical competence. Finally, a dual process theory of reasoning, with broad implications and connections with other fields of psychology, is elaborated and assessed in the light of recent evidence. (shrink)

Renowned moral philosopher Jonathan Glover confronts the brutal history of the twentieth century to unravel the mystery of why so many atrocities occurred. In a new preface, Glover brings the book through the post-September 11 era and into our own time—and asks whether humankind can "weaken the grip war has on us." _Praise for the first edition:_ “It is hard to imagine a more important book. Glover makes an overwhelming case for the need to understand our own inhumanity, and (...) reduce or eliminate the ways in which it can express itself—and he then begins the task himself. _Humanity _is_ _an extraordinary achievement.”—Peter Singer, Princeton University “This is an extraordinary book: brilliant, haunting and uniquely important. Almost 40 years ago a president read a best seller and avoided a holocaust. I like to think that some of the leaders and followers of tomorrow will read _Humanity._”_—_Steven Pinker, _New York Times Book Review_. (shrink)

Conditionalization and Jeffrey Conditionalization cannot simultaneously satisfy two widely held desiderata on rules for empirical learning. The first desideratum is confirmational holism, which says that the evidential import of an experience is always sensitive to our background assumptions. The second desideratum is commutativity, which says that the order in which one acquires evidence shouldn't affect what conclusions one draws, provided the same total evidence is gathered in the end. (Jeffrey) Conditionalization cannot satisfy either of these desiderata without violating the other. (...) This is a surprising problem, and I offer a diagnosis of its source. I argue that (Jeffrey) Conditionalization is inherently anti-holistic in a way that is just exacerbated by the requirement of commutativity. The dilemma is thus a superficial manifestation of (Jeffrey) Conditionalization's fundamentally anti-holistic nature. (shrink)

For a century at least, parties have been central to the study of politics. Yet their typical conceptual reduction to a network of power-seeking elites has left many to wonder why parties were ever thought crucial to democracy. This book seeks to retrieve a richer conception of partisanship, drawing on modern political thought and extending it in the light of contemporary democratic theory and practice. Looking beyond the party as organization, the book develops an original account of what it is (...) to be a partisan. It examines the ideas, orientations, obligations, and practices constitutive of partisanship properly understood, and how these intersect with the core features of democratic life. Such an account serves to underline in distinctive fashion why democracy needs its partisans, and puts in relief some of the key trends of contemporary politics. (shrink)

I argue that there can be no such thing as a borderline case of the predicate ‘phenomenally conscious’: for any given creature at any given time, it cannot be vague whether that creature is phenomenally conscious at that time. I first defend the Positive Characterization Thesis, which says that for any borderline case of any predicate there is a positive characterization of that case that can show any sufficiently competent speaker what makes it a borderline case. I then appeal to (...) the familiar claim that zombies are conceivable, and I argue that this claim entails that there can be no positive characterizations of borderline cases of ‘phenomenally conscious’. By the Positive Characterization Thesis, it follows that ‘phenomenally conscious’ can not have any borderline cases. (shrink)

Personal autonomy is often lauded as a key value in contemporary Western bioethics. Though the claim that there is an important relationship between autonomy and rationality is often treated as uncontroversial in this sphere, there is also considerable disagreement about how we should cash out the relationship. In particular, it is unclear whether a rationalist view of autonomy can be compatible with legal judgments that enshrine a patient's right to refuse medical treatment, regardless of whether the reasons underpinning the choice (...) are known and rational, or indeed whether they even exist. Jonathan Pugh brings recent philosophical work on the nature of rationality to bear on the question of how we should understand personal autonomy in contemporary bioethics. In doing so, he develops a new framework for thinking about the concept of autonomy, one that is grounded in an understanding of the different roles that rational beliefs and rational desires have to play in it. Pugh's account allows for a deeper understanding of d the relationship between our freedom to act and our capacity to decide autonomously. His rationalist perspective is contrasted with other prominent accounts of autonomy in bioethics, and the revisionary implications it has for practical questions in biomedicine are also outlined.

Progress in genetic and reproductive technology now offers us the possibility of choosing what kinds of children we do and don't have. Should we welcome this power, or should we fear its implications? There is no ethical question more urgent than this: we may be at a turning-point in the history of humanity. The renowned moral philosopher and best-selling author Jonathan Glover shows us how we might try to answer this question, and other provoking and disturbing questions to which (...) it leads. Surely parents owe it to their children to give them the best life they can? Increasingly we are able to reduce the number of babies born with disabilities and disorders. But there is a powerful new challenge to conventional thinking about the desirability of doing so: this comes from the voices of those who have these conditions. They call into question the very definition of disability. How do we justify trying to avoid bringing people like them into being? In 2002 a deaf couple used sperm donated by a friend with hereditary deafness to have a deaf baby: they took the view that deafness is not a disability, but a difference. Starting with the issues raised by this case, Jonathan Glover examines the emotive idea of 'eugenics', and the ethics of attempting to enhance people, for non-medical reasons, by means of genetic choices. Should parents be free, not only to have children free from disabilities, but to choose, for instance, the colour of their eyes or hair? This is no longer a distant prospect, but an existing power which we cannot wish away. What impact will such interventions have, both on the individuals concerned and on society as a whole? Should we try to make general improvements to the genetic make-up of human beings? Is there a central core of human nature with which we must not interfere? This beautifully clear book is written for anyone who cares about the rights and wrongs of parents' choices for their children, anyone who is concerned about our human future. Glover handles these uncomfortable questions in a controversial but always humane and sympathetic manner. (shrink)

The bootstrapping problem poses a general challenge, afflicting even strongly internalist theories. Even if one must always know that one’s source is reliable to gain knowledge from it, bootstrapping is still possible. I survey some solutions internalists might offer and defend the one I find most plausible: that bootstrapping involves an abuse of inductive reasoning akin to generalizing from a small or biased sample. I also argue that this solution is equally available to the reliabilist. The moral is that the (...) issues raised by bootstrapping are orthogonal to questions about internalism and basic knowledge, having more to do with the nature of good inductive reasoning. (shrink)

Recent proposals that frame norms of action in terms of knowledge have been challenged by Bayesian decision theorists. Bayesians object that knowledge-based norms conflict with the highly successful and established view that rational action is rooted in degrees of belief. I argue that the knowledge-based and Bayesian pictures are not as incompatible as these objectors have made out. Attending to the mechanisms of practical reasoning exposes space for both knowledge and degrees of belief to play their respective roles.

A neurologist presents evidence for locating the unconscious--Freud's concept--within the actual physiology of the brain, in a study that explains current knowledge about perception, memory, sleep, dreams, and Freud's theory of the unconscious.

The Wide-Scope view of instrumental reason holds that you should not intend an end without also intending what you believe to be the necessary means. This, the Wide-Scoper claims, provides the best account of why failing to intend the believed means to your end is a rational failing. But Wide-Scopers have struggled to meet a simple Explanatory Challenge: why shouldn't you intend an end without intending the necessary means? What reason is there not to do so? In the first half (...) of this paper, I argue that the Wide-Scope view struggles to meet this challenge because it takes the principles of instrumental reason to have unlimited application—to apply to all agents, in all circumstances. I then go on to offer a new account of these principles. The new account is very much in the spirit of the Wide-Scope view, and shares its central advantages, but lacks its unlimited application. This view should, therefore, find the Explanatory Challenge more tractable. In the second half of the paper, I argue that this prediction is confirmed. If the requirements of instrumental reason apply only when a means is, or is believed to be, necessary for your end, then plausible independent claims, about reasons, rationality, and intentions, explain why failing to intend the necessary means to your ends is a rational failing.

Forty years ago, Bayesian philosophers were just catching a new wave of technical innovation, ushering in an era of scoring rules, imprecise credences, and infinitesimal probabilities. Meanwhile, down the hall, Gettier’s 1963 paper [28] was shaping a literature with little obvious interest in the formal programs of Reichenbach, Hempel, and Carnap, or their successors like Jeffrey, Levi, Skyrms, van Fraassen, and Lewis. And how Bayesians might accommodate the discourses of full belief and knowledge was but a glimmer in the eye (...) of Isaac Levi. Forty years later, scoring rules, imprecise credences, and infinitesimal probabilities are all the rage. And the formal and “informal” traditions are increasingly coming together as Bayesian arguments spill over into debates about the foundations of empirical knowledge, skepticism, and more. Relatedly, Bayesian interest in full belief and knowledge has never been greater. Much more besides has happened in the last forty years of Bayesian philosophy, .. (shrink)

Current accounts suggest that self-referential thought serves a pivotal function in the human ability to simulate the future during mind-wandering. Using experience sampling, this hypothesis was tested in two studies that explored the extent to which self-reflection impacts both retrospection and prospection during mind-wandering. Study 1 demonstrated that a brief period of self-reflection yielded a prospective bias during mind-wandering such that participants’ engaged more frequently in spontaneous future than past thought. In Study 2, individual differences in the strength of self-referential (...) thought — as indexed by the memorial advantage for self rather than other-encoded items — was shown to vary with future thinking during mind-wandering. Together these results confirm that self-reflection is a core component of future thinking during mind-wandering and provide novel evidence that a key function of the autobiographical memory system may be to mentally simulate events in the future.

Task unrelated thought (TUT) refers to thought directed away from the current situation, for example a daydream. Three experiments were conducted on healthy participants, with two broad aims. First, to contrast distributed and encapsulated views of cognition by comparing the encoding of categorical and random lists of words (Experiments One and Two). Second, to examine the consequences of experiencing TUT during study on the subsequent retrieval of information (Experiments One, Two, and Three). Experiments One and Two demonstrated lower levels of (...) TUT and higher levels of word-fragment completion whilst encoding categorical relative to random stimuli, supporting the role of a distributed resource in the maintenance of TUT. In addition the results of all three experiments suggested that experiencing TUT during study had a measurable effect on subsequent retrieval. TUT was associated with increased frequency of false alarms at retrieval (Experiment One). In the subsequent experiments TUT was associated with no advantage to retrieval based on recollection, by manipulating instructions at encoding (Experiment Two), and/or at retrieval (Experiment Three). The implications of the results of all three experiments are discussed in terms of recent accounts of memory retrieval and conscious awareness. (shrink)

'If' is one of the most important words in the English language, being used to express hypothetical thought. The use of conditional terms such as 'if' distinguishes human intelligence from that of all other animals. In this volume, Jonathan Evans and David Over present a new theoretical approach to understanding conditionals. The book draws on studies from the psychology of judgement and decision making, as well as philosophical logic.

When is it morally permissible to engage in self-defense or the defense of others? Jonathan Quong gives an original philosophical account of the central moral principles that should regulate the use of defensive force. The morality of defensive force needs to be understood in the context of a more general account of justice and moral rights.

In order for Herman Cappelen to argue in his Philosophy Without Intuitions that philosophers have been on the whole mistaken in thinking that we actually use intuitions much at all in our first-order philosophizing, he must attempt the task of characterizing what something must be, in order to be an intuition.My discussion here is focused on the latter half of the book concerning the “argument from philosophical practice. I am in wholehearted agreement with the first half’s thesis that the usage (...) of the term “intuition” is highly motley and of no methodological use. I truly sympathize with the frustration he evidently feels at wrangling with that task, because I’ve felt the same in my own project critiquing what I do take to be a fairly common practice in contemporary philosophy that we often gesture at when we speak of intuitions. For the literature on intuitions can be a total mess on even the most basic questions about what intuitions are: beliefs, or sui generis seemings? Special in .. (shrink)

Enkratic reasoning—reasoning from believing that you ought to do something to an intention to do that thing—seems good. But there is a puzzle about how it could be. Good reasoning preserves correctness, other things equal. But enkratic reasoning does not preserve correctness. This is because what you ought to do depends on your epistemic position, but what it is correct to intend does not. In this paper, I motivate these claims and thus show that there is a puzzle. I then (...) argue that the best solution is to deny that correctness is always independent of your epistemic position. As I explain, a notable upshot is that a central epistemic norm directs us to believe, not simply what is true, but what we are in a position to know. (shrink)

We have made huge progress in understanding the biology of mental illnesses, but comparatively little in interpreting them at the psychological level. The eminent philosopher Jonathan Glover believes that there is real hope of progress in the human interpretation of disordered minds. -/- The challenge is that the inner worlds of people with psychiatric disorders can seem strange, like alien landscapes, and this strangeness can deter attempts at understanding. Do people with disorders share enough psychology with other people to (...) make interpretation possible? To explore this question, Glover tackles the hard cases—the inner worlds of hospitalized violent criminals, of people with delusions, and of those diagnosed with autism or schizophrenia. Their first-person accounts offer glimpses of inner worlds behind apparently bizarre psychiatric conditions and allow us to begin to learn the “language” used to express psychiatric disturbance. Art by psychiatric patients, or by such complex figures as van Gogh and William Blake, give insight when interpreted from Glover’s unique perspective. He also draws on dark chapters in psychiatry’s past to show the importance of not medicalizing behavior that merely transgresses social norms. And finally, Glover suggests values, especially those linked with agency and identity, to guide how the boundaries of psychiatry should be drawn. -/- Seamlessly blending philosophy, science, literature, and art, Alien Landscapes? is both a sustained defense of humanistic psychological interpretation and a compelling example of the rich and generous approach to mental life for which it argues.

The capacity to self-generate mental content that is unrelated to the current environment is a fundamental characteristic of the mind, and the current experiment explored how this experience is related to the decisions that people make in daily life. We examined how task-unrelated thought varies with the length of time participants are willing to wait for an economic reward, as measured using an inter-temporal discounting task. When participants performed a task requiring minimal attention, the greater the amount of time spent (...) engaged in TUT the longer the individual was prepared to wait for an economic reward. These data indicate that self-generated thought engages processes associated with the successful management of long-term goals. Although immersion in the here and now is undeniably advantageous, under appropriate conditions the capacity to let go of the present and consider more pertinent personal goals may have its own rewards.

This book provides readers with an introduction to epistemology within the Buddhist intellectual tradition. It is designed to be accessible to those whose primary background is in the “Western” tradition of philosophy and who have little or no previous exposure to Buddhist philosophical writings. The book examines many of the most important topics in the field of epistemology, topics that are central both to contemporary discussions of epistemology and to the classical Buddhist tradition of epistemology in India and Tibet. Among (...) the topics discussed are Buddhist accounts of: the nature of knowledge episodes, the defining conditions of perceptual knowledge and of inferential knowledge, the status of testimonial knowledge, and skeptical criticisms of the entire project of epistemology. The book seeks to put the field of Buddhist epistemology in conversation with contemporary debates in philosophy. It shows that many of the arguments and debates occurring within classical Buddhist epistemological treatises coincide with the arguments and disagreements found in contemporary epistemology. The book shows, for example, how Buddhist epistemologists developed an anti-luck epistemology—one that is linked to a sensitivity requirement for knowledge. Likewise, the book explores the question of how the study of Buddhist epistemology can be of relevance to contemporary debates about the value of contributions from experimental epistemology, and to broader debates concerning the use of philosophical intuitions about knowledge.

Embodied cognition has attracted significant attention within cognitive science and related fields in recent years. It is most noteworthy for its emphasis on the inextricable connection between mental functioning and embodied activity and thus for its departure from standard cognitive science's implicit commitment to the unembodied mind. This article offers a review of embodied cognition's recent empirical and theoretical contributions and suggests how this movement has moved beyond standard cognitive science. The article then clarifies important respects in which embodied cognition (...) has not departed fundamentally from the standard view. A shared commitment to representationalism, and ultimately, mechanism, suggest that the standard and embodied cognition movements are more closely related than is commonly acknowledged. Arguments against representationalism and mechanism are reviewed and an alternative position that does not entail these conceptual undergirdings is offered. (shrink)

Webber argues for a new interpretation of Sartrean existentialism. On this reading, Sartre is arguing that each person’s character consists in the projects they choose to pursue and that we are all already aware of this but prefer not to face it. Careful consideration of his existentialist writings shows this to be the unifying theme of his theories of consciousness, freedom, the self, bad faith, personal relationships, existential psychoanalysis, and the possibility of authenticity. Developing this account affords many insights into (...) various aspects of his philosophy, not least concerning the origins, structure, and effects of bad faith and the resulting ethic of authenticity. This discussion makes clear the contributions that Sartre’s work can make to current debates over the objectivity of ethics and the psychology of agency, character, and selfhood. Written in an accessible style and illustrated with reference to Sartre’s fiction, this book should appeal to general readers and students as well as to specialists. (shrink)

The practice of appealing to esoteric intuitions, long standard in analytic philosophy, has recently fallen on hard times. Various recent empirical results have suggested that philosophers are not currently able to distinguish good intuitions from bad. This paper evaluates one possible type of approach to this problematic methodological situation: calibration. Both critiquing and building on an argument from Robert Cummins, the paper explores what possible avenues may exist for the calibration of philosophical intuitions. It is argued that no good options (...) are currently available, but leaves open the real possibility of such a calibration in the future. (shrink)

How do our engagements with fictions and other products of the imagination compare to our experiences of the real world? Are the feelings we have about a novel's characters modelled on our thoughts about actual people? If it is wrong to feel pleasure over certain situations in real life, can it nonetheless be right to take pleasure in analogous scenarios represented in a fantasy or film? Should the desires we have for what goes on in a make-believe story cohere with (...) what we want to happen in the actual world? In Apt Imaginings, Jonathan Gilmore develops a new framework to pursue these questions, marshalling a wide range of research in aesthetics, the science of the emotions, moral philosophy, neuroscience, cognitive psychology, and film and literary theory. Gilmore argues that, while there is a substantial empirical continuity in our feelings across art and life, the norms that govern the appropriateness of those responses across the divide are discontinuous. In this view, the evaluative criteria that determine the fit, correctness, or rationality of our emotions and desires for what is internal to a fiction can be contrary to those that govern our affective attitudes toward analogous things in the real world. In short, it can be right to embrace within a story what one would condemn in real life. The theory Gilmore defends in this volume helps to explain our complex and sometimes conflicted attitudes toward works of the imagination; challenges the popular view that fictions serve to refine our moral sensibilities; and exposes a kind of autonomy of the imagination that can render our responses to art immune to standard real-world epistemic, practical, and affective kinds of criticism.

Contemporary political theory has made the question of the “people” a topic of sustained analysis. This article identifies two broad approaches taken—norm-based and contestation-based—and, noting some problems left outstanding, goes on to advance a complementary account centred on partisan practice. It suggests the definition of “the people” is closely bound up in the analysis of political conflict, and that partisans engaged in such conflict play an essential role in constructing and contesting different principled conceptions. The article goes on to show (...) how such an account does not lead to a normatively hollow, purely historical conception of “the people,” but rather highlights the normative importance of practices that, at the minimum, de-naturalise undesirable conceptions of the people and, at their best, give political legitimacy and a representative basis to those one might wish to see prosper.

This paper articulates a new understanding of Sartre’s philosophical methodology in his early publications up to and including Being and Nothingness. Through his critique of Husserl across these works, Sartre develops an original and sophisticated variety of transcendental phenomenology. He was attracted to Husserl’s philosophy for its promise to establish the foundations of empirical psychology but ultimately concluded that it could not fulfil this promise. Through the analyses that led him to this conclusion, Sartre formulated a new kind of phenomenological (...) reduction and a distinctive kind of transcendental argument to draw conclusions about mind-independent reality from phenomenological premises. His aims were to dissolve the traditional distinction between mind and world, to establish that the mind is accessible to empirical study, and to formulate the conceptual framework required to study the mind systematically. Sartre’s philosophy of psychology, therefore, drove the philosophical development of the methodological foundation of his philosophical project. (shrink)

Geoffrey Scarre has recently argued that the version of qualitative hedonism which I attribute to Mill is unsatisfactory for various reasons. In his view, even if it is formally compatible with value monism, involves non-hedonistic elements and offers an implausible account of the relationship between and pleasures. In this paper, I show that his objections, which are similar in spirit to those pressed earlier by Bradley, Moore and others against Mill, are unfounded where not confused. The Mill/Riley line does not (...) rely on non-hedonistic standards and has sufficient flexibility to account for many different kinds of pleasures and pleasing activities. It remains a coherent version of qualitative hedonism, worthy of further consideration and study. (shrink)

We have known for a long time that there is complex, intelligent life. More recently we have discovered that the physics of our universe is fine-tuned so as to allow for the existence of such life. Call these two observations the Old Datum and the New Datum, respectively. Our question here is: once we know the Old Datum, does the New Datum provide additional evidence for the design hypothesis? I argue that it does not. Thus, there is an important sense (...) in which the much-touted fine-tuning of physics is irrelevant to debates about design. (shrink)

A number of recent accounts of our first-person knowledge of our attitudes give a central role to transparency - our capacity to answer the question of whether we have an attitude by answering the question of whether to have it.

Resurgent interest in both mechanistic and counterfactual theories of explanation has led to a fair amount of discussion regarding the relative merits of these two approaches. James Woodward is currently the pre-eminent counterfactual theorist, and he criticizes the mechanists on the following grounds: Unless mechanists about explanation invoke counterfactuals, they cannot make sense of claims about causal interactions between mechanism parts or of causal explanations put forward absent knowledge of productive mechanisms. He claims that these shortfalls can be offset if (...) mechanists will just borrow key tenets of his counterfactual theory of causal claims. What mechanists must bear in mind, however, is that by pursuing this course they risk both the assimilation of the mechanistic theories of explanation into Woodward’s own favored counterfactual theory, and they risk the marginalization of mechanistic explanations to a proper subset of all explanations. An outcome more favorable to mechanists might be had by pursuing an actualist-mechanist theory of the contents of causal claims. While it may not seem obvious at first blush that such an approach is workable, even in principle, recent empirical research into causal perception, causal belief, and mechanical reasoning provides some grounds for optimism.

John Gray, much influenced by Isaiah Berlin and building on work by the late John Rees and the late Fred Berger, has recently stated three ‘fatal’ objections which virtually all analysts seem to find persuasive against John Stuart Mill's classic doctrine of liberty. First, Gray thinks it ‘an obvious objection to Mill's project that conceptions of harm vary with competing moral outlooks, so that no Principle of Liberty whose application turns on judgements about harm can expect to resolve disputes between (...) exponents of opposed moral perspectives’. Even if we overlook Mill's strange silence in the matter and supply him with a reasonable definition of harm, it remains clear that the liberty principle ‘is not, and cannot be, the very simple principle Mill sought’. For ‘Mill's principle is in its very nature radically incomplete. It tells us what we may not do, but not what we ought to do.’ To know when liberty should in fact be restrained, ‘we must look to other principles—chiefly the Principle of Utility itself’. But if general utility alone can ‘tell us how much liberty may be given up for how much harm-prevention’, then ‘there can be no question of adherence to [an] exceptionless principle such as Mill's Principle of Liberty’. Thus, even if we believe that Mill's version of utilitarianism is coherent, his judgements about the regulation of conduct must depend on a highly complex and controversial moral doctrine. (shrink)
