What is Derrida Saying to Us - Abstract Jacques Derrida is difficult and controversial. This article concentrates on the first part of On Grammatology (1967) as the Rosetta Stone to understanding him. It examines concepts such as the metaphysics of presence, the trace, differance, and deconstruction, aiming to interest readers further in pursuing him in more depth.

"On First Looking into Chapman's Homer" by John Keats, may seem archaic now, especially its language. But it expresses the poet's delight and excitement when he discovers a new literary revelation, hitherto hidden from him. He makes an intellectual discovery. I've had this sense of discovery when reading philosophy. Some new approach, some new idea, has made me see a concept I thought I understood in a different and more rigorous way; made me re- examine what I thought I'd understood (...) perfectly well before. It's not so much that the authors I was reading offered the last word on the subject, more that they offered the first word. Here are four examples. (shrink)

This is an imagined dialogue about this book, which is one of the most influential but difficult works written in the twentieth century.

This essay examines three approaches to the concept of death: an existential approach by Heidegger, a pragmatic evaluation by Nagel, and an experiential account by Philip Gould, who was not a professional philosopher but who wrote a detailed description of the time before his death from cancer. It compares and contrasts the different approaches, and uses Gould's account as a real a life check on the two philosophical analyses.

There are few if any good summaries of this neglected work on the internet, or even in publication generally. The one given here is more extensive than most, and points out the wisdom and erudition of Kant's thinking about freedom of the will. It also paves the way for another article already on this website on Kant’s view of the world in general.

This article consists of notes on Kant’s preparatory work on morality. I am indebted to Paton’s comments in his translation, and these are acknowledged in the text. As with the companion article on the “Critique of Practical Reason”, I am making preparations here for a later summary of Kant’s view of the world in general. .

Of all the great philosophers, Hegel is one of the most difficult to understand, and, at least by some philosophers, one of the most despised. Russell and Schopenhauer thought that his philosophy was devoid of any useful meaning, and Popper blamed him for the rise of totalitarianism. This teaching paper aims to summarise the main points of his work and give a balanced view.

This essay is about the way Kant sees the world rather than about his moral philosophy and his theories of justice. It concentrates on perception of the physical world, and how far this can take us in understanding the world of the mind and how we think and make decisions about our lives. It proposes that Kant can be seen as the founder not just of theories of the problem of knowledge, but also of such modern ideas as existentialism.

There seems to me to be a problem with the interpretation of Jean-Paul Sartre’s use of the words “being” and “nothingness” in his philosophy. Is his idea of being the same as that of Heidegger? While I’m quite sure of the metaphysical aspects of the argument, I’m not sure whether within those aspects Sartre equates nothingness with freedom, or whether the freedom (of action) arises from the nothingness. This short essay attempts to find a solution to the problem.

In an ideal, ordered world, answering metaethical questions (such as “what is goodness?” and “how can we tell the good from the bad”) would lead to statements about morality (principles set out for making decisions, having intentions and taking actions). However, the world is not ideal or ordered, and in life principles for moral action are based on various beliefs, religions and cultures and most of all by the background of the actor him/herself. -/- This corresponds to the view of (...) the great German philosopher Frederik Nietzsche, who Simon Blackburn (Blackburn, 2005) refers to as the “arch debunker”. Blackburn rates Nietzsche as “currently the most influential of the great philosophers” and there is certainly an arguable case for that assessment. Nietzsche is regarded as the bad boy of philosophy, the writer who speaks the unspeakable. But his ideas have been taken up by philosophers who came after him like no other. His views (along with Kierkegaard’s) lead to existentialism. Heidegger based much of his writing on Nietzsche, and the questions Nietzsche raises (but does not necessarily answer) about epistemology, ethics, religion, psychology, and the way we live our lives are profound and still puzzle modern philosophers and social scientists. -/- This article reviews Nietzsche's profound thoughts on these issues. -/- .

Language is what separates us from other animals, and is why we are able to solve complex logical problems, and, as far as we can tell, experience consciousness. Wittgenstein is the philosopher of language par excellence. He asks: what is the role of language in philosophy, and in the wider sphere of thinking in everyday life? This teaching paper gives a summary of his ideas.

‘There is no place in the phenomenology of fully absorbed coping’, writes Hubert Dreyfus, ‘for mindfulness. In flow, as Sartre sees, there are only attractive and repulsive forces drawing appropriate activity out of an active body’1. Among the many ways in which history animates dynamical systems at a range of distinctive timescales, the phenomena of embodied human habit, skilful movement, and absorbed coping are among the most pervasive and mundane, and the most philosophically puzzling. In this essay we examine both (...) habitual and skilled movement, sketching the outlines of a multidimensional framework within which the many differences across distinctive cases and domains might be fruitfully understood. Both the range of movement phenomena which can plausibly be seen as instances of habit or skill, and the space of possible theories of such phenomena are richer and more disparate than philosophy easily encompasses. We seek to bring phenomenology into contact with relevant movements in psychological theories of skilful action, in the belief that phenomenological philosophy and cognitive science can be allies rather than antagonists.

Philosophy and Memory Traces defends two theories of autobiographical memory. One is a bewildering historical view of memories as dynamic patterns in fleeting animal spirits, nervous fluids which rummaged through the pores of brain and body. The other is new connectionism, in which memories are 'stored' only superpositionally, and reconstructed rather than reproduced. Both models, argues John Sutton, depart from static archival metaphors by employing distributed representation, which brings interference and confusion between memory traces. Both raise urgent issues about (...) control of the personal past, and about relations between self and body. Sutton demonstrates the role of bizarre body fluids in moral physiology, as philosophers from Descartes and Locke to Coleridge struggled to control their own innards and impose cognitive discipline on 'the phantasmal chaos of association'. Going on to defend connectionism against Fodor and critics of passive mental representations, he shows how problems of the self are implicated in cognitive science. (shrink)

Rather than conserving or ignoring historically burdened heritage, RAAAF intervene. Their responses are striking, sometimes dramatic or destructive. Prompted by Rietveld’s discussion of the Luftschloss project, I compare some other places with difficult pasts which engage our embodied and sensory responses, without such active redirection or disruption. Ross Gibson’s concept of a ‘memoryscope’ helps us identify distinct but complementary ways of focussing the forces of the past. Emotions and imaginings are transmitted over time in many forms. The past is not (...) easily washed, blasted or sliced away. By considering other settings and modes of encounter, we can recognise and applaud the novelty of RAAAF’s interventions while urging further attention to the variable dynamics and rhythms of remembering and of sociomaterial residues.

Open peer commentary on the article “Beyond Individual-Centred 4E Cognition: Systems Biology and Sympoiesis” by Mads Julian Dengsø & Michael David Kirchhoff. Abstract: Dengsø and Kirchhoff offer a revised dynamic conception of the individual in place of the bounded cognitive agent of classical cognitive science. However, this may not be sufficiently robust to ground the enquiries into individual and cultural differences that remain vital in the proposed “deterritorialized cognitive science.” It also needs to make contact with rich traditions of 4E (...) research on socially distributed cognition, which are neglected in Dengsø and Kirchhoff’s critique. It is just because individualization is a fragile process, and because boundaries are hard-won achievements, that anti-individualists who highlight the multiplicity, heterogeneity, and dynamism of cognitive ecologies must reconfigure rather than eliminate or efface the individual.

In Tulving’s initial characterization, episodic memory was one of multiple memory systems. It was postulated, in pursuit of explanatory depth, as displaying proprietary operations, representations, and substrates such as to explain a range of cognitive, behavioural, and experiential phenomena. Yet the subsequent development of this research program has, paradoxically, introduced surprising doubts about the nature, and indeed existence, of episodic memory. On dominant versions of the ‘common system’ view, on which a single simulation system underlies both remembering and imagining, there (...) are no processes unique to memory to support robust generalizations with inductive potential. Eliminativism about episodic memory seems to follow from the claim that it has no dedicated neurocognitive system of its own. After identifying this under-noticed threat, we push back against modern eliminativists by surveying recent evidence that still indicates specialized mechanisms, computations, and representations that are distinctly mnemic in character. We argue that contemporary realists about episodic memory can retain lessons of the common system approach while resisting the further move to eliminativism. (shrink)

This paper introduces a new, expanded range of relevant cognitive psychological research on collaborative recall and social memory to the philosophical debate on extended and distributed cognition. We start by examining the case for extended cognition based on the complementarity of inner and outer resources, by which neural, bodily, social, and environmental resources with disparate but complementary properties are integrated into hybrid cognitive systems, transforming or augmenting the nature of remembering or decision-making. Adams and Aizawa, noting this distinctive complementarity argument, (...) say that they agree with it completely: but they describe it as “a non-revolutionary approach” which leaves “the cognitive psychology of memory as the study of processes that take place, essentially without exception, within nervous systems.” In response, we carve out, on distinct conceptual and empirical grounds, a rich middle ground between internalist forms of cognitivism and radical anti-cognitivism. Drawing both on extended cognition literature and on Sterelny’s account of the “scaffolded mind” (this issue), we develop a multidimensional framework for understanding varying relations between agents and external resources, both technological and social. On this basis we argue that, independent of any more “revolutionary” metaphysical claims about the partial constitution of cognitive processes by external resources, a thesis of scaffolded or distributed cognition can substantially influence or transform explanatory practice in cognitive science. Critics also cite various empirical results as evidence against the idea that remembering can extend beyond skull and skin. We respond with a more principled, representative survey of the scientific psychology of memory, focussing in particular on robust recent empirical traditions for the study of collaborative recall and transactive social memory. We describe our own empirical research on socially distributed remembering, aimed at identifying conditions for mnemonic emergence in collaborative groups. Philosophical debates about extended, embedded, and distributed cognition can thus make richer, mutually beneficial contact with independently motivated research programs in the cognitive psychology of memory.

Martin and Deutscher’s remarkable 1966 paper ‘Remembering’ still offers great riches to memory researchers across distinctive traditions, both in its methodological ambition (successfully marrying phenomenological and causal discourses) and in its content. In this short discussion, after briefly setting the paper in its context, we hone in on two live and under-explored issues which have gained attention recently under new labels – the extended mind hypothesis, and the constructive nature of memory. We suggest that Martin and Deutscher’s causal analysis of (...) memory is compatible with the idea that activities of remembering may be distributed across heterogeneous social and external resources, focussing in on their neglected example of creatures who ‘remember as we do’ as long as they carry round metal boxes which are given to them at birth. We then argue that the causal analysis is in some tension with the extent to which remembering is a constructive activity, because there may be no clear way to determine the appropriate ‘limits of accuracy’ within which a past event or experience must be represented.

Remembering is one of the most characteristic and most puzzling of human activities. Personal memory, in particular – the ability mentally to travel back into the past, as leading psychologist Endel Tulving puts it – often has intense emotional or moral significance: it is perhaps the most striking manifestation of the peculiar way human beings are embedded in time, and of our limited but genuine freedom from our present environment and our immediate needs. Memory has been significant in the history (...) of philosophy as much in relation to ethics and to epistemology as in theories of psyche, mind, and self. (shrink)

The minimal God exemplifies essential omnipotence, omniscience, and moral perfection, but none of the other properties of the traditional God. I examine the consequences of the minimal God in augmented S5, S4, and Kρσ. The metaphysical consequences for the minimal God in S5 include the impossibility that God—or any other object—might acquire, lose, or exchange an essential property. It is impossible that an essentially divine being might become essentially human, for instance. The epistemological consequences include the impossibility of agnosticism—it is (...) impossible that P(◻︎FG |E) = P(~◻︎FG| E). Indeed, every weaker forms of agnosticism are also impossible—it is impossible that P(◻︎FG |E) = n, n(0 < n < 1). The metaphysical and epistemological consequences for the minimal God in S4 are equally untenable. I show that we can avoid all of these unwelcome epistemological consequences for the minimal God in Kρσ. But Kρσ has some extraordinary metaphysical consequences for the minimal God. All of the problems for the minimal God generalize to the maximal God. (shrink)

The dead donor rule justifies current practice in organ procurement for transplantation and states that organ donors must be dead prior to donation. The majority of organ donors are diagnosed as having suffered brain death and hence are declared dead by neurological criteria. However, a significant amount of unrest in both the philosophical and the medical literature has surfaced since this practice began forty years ago. I argue that, first, declaring death by neurological criteria is both unreliable and unjustified but (...) further, the ethical principles which themselves justify the dead donor rule are better served by abandoning that rule and instead allowing individuals who have suffered severe and irreversible brain damage to become organ donors, even though they are not yet dead and even though the removal of their organs would be the proximal cause of death.

Lloyd Jones’s *The Book of Fame*, a novel about the stunningly successful 1905 British tour of the New Zealand rugby team, represents both skilled group action and the difficulty of capturing it in words. The novel’s form is as fluid and deceptive, as adaptable and integrated, as the sweetly shaped play of the team that became known during this tour for the first time as the All Blacks. It treats sport on its own terms as a rich world, a set (...) of bodily skills, and an honest profession in itself. A reading of *The Book of Fame* can contribute to the interdisciplinary study of literature and cognition, exemplifying two-way ‘exchange values’. On the one hand, we gain insights into the nature of skilful group agency, of distinct forms and at distinct timescales, by focussing on the precise forms taken by the All Blacks’ creation of space. Here, we treat The Book of Fame as a brilliant evocation of features of collective thought, movement, and emotion that both everyday and scientific inquiry can easily miss. On the other hand, we also read back into the novel a subtle, fascinated interrogation of the mechanisms by which small groups form, evolve, and act. In this more ambitious mode of analysis, we use independently motivated theoretical concerns to help us see real features of the literary work that might otherwise remain invisible. We focus on the relationship between skilful performance and collective action. These topics fall outside the ambit of much current work by literary theorists using cognitive research, who tend to focus on theory of mind and modularity, metaphor and blending, emotion and empathy, consciousness and concepts, representation and so on. But skilled performance and collective action comprise surprisingly lively research fields across the sciences, from neuropsychology to philosophy of mind and cognitive anthropology. These areas of inquiry may provide even more productive avenues for future work in the interfield of literary and cultural theory and the cognitive sciences. (shrink)

Sutton's review of Renaissance Magic and the Return of the Golden Age.

The paper aims to show that, if S5 is the logic of metaphysical necessity, then no state of affairs in any possible world constitutes any non-trivial evidence for or against the existence of the traditional God. There might well be states of affairs in some worlds describing extraordinary goods and extraordinary evils, but it is false that these states of affairs constitute any (non-trivial) evidence for or against the existence of God. The epistemological and metaphysical consequences for philosophical theology of (...) assuming that S4 or Kσρ is the logic of metaphysical necessity are equally untenable. S4 guarantees that God does not exist if there is the slightest evidence against the existence of God. And Kσρ guarantees that God might survive the loss or acquisition of any essential property at all. (shrink)

Synthesizing the domains of investigation highlighted in current research in distributed cognition and related fields, this paper offers an initial taxonomy of the overlapping types of resources which typically contribute to distributed or extended cognitive systems. It then outlines a number of key dimensions on which to analyse both the resulting integrated systems and the components which coalesce into more or less tightly coupled interaction over the course of their formation and renegotiation.

According to Paul Draper and Ryan Nichols the practice of philosophy of religion—and especially its theistically committed practitioners—regularly violate norms of rationality, objectivity, and impartiality in the review, assessment, and weighing of evidence. (Draper and Nichols, 2013). We consider the charge of epistemic partisanship and show that the observational data does not illustrate a norm-violating form of inquiry. The major oversight in the charge of epistemic partiality is the epistemically central role of prior probabilities in determining the significance of incongruent (...) evidence. We argue that reasonably divergent views on the likelihood of theism on incongruent evidence can also account for differences in significance. We conclude that it is an epistemic requirement that committed theists regard incongruent evils as much less significant evidence against theism than do lukewarm theists, agnostics, or atheists. Differences in the significance of evidence quite properly reflect differences in commitments to theism. (shrink)

Through a selective historical, theoretical, and critical survey of the uses of the concept of scaffolding over the past 30 years, this chapter traces the development of the concept across developmental psychology, educational theory, and cognitive anthropology, and its place in the interdisciplinary field of distributed cognition from the 1990s. Offering a big-picture overview of the uses of the notion of scaffolding, it suggests three ways to taxonomise forms of scaffolding, and addresses the possible criticism that the metaphor of scaffolding (...) retains an overly individualist vision of cognition. The chapter is aimed at a broad interdisciplinary audience interested in processes of learning, teaching, and apprenticeship as they apply to the study of memory. (shrink)

Traces of many past events are often layered or superposed, in brain, body, and world alike. This often poses challenges for individuals and groups, both in accessing specific past events and in regulating or managing coexisting emotions or attitudes. We sometimes struggle, for example, to find appropriate modes of engagement with places with complex and difficult pasts. More generally, there can appear to be a tension between what we know about the highly constructive nature of remembering, whether it is drawing (...) on neural or worldly resources or both, and the ways that we need and use memory to make claims on the past, and to maintain some appropriate causal connections to past events. I assess the current state of work on situated affect and distributed memory, and the recent criticisms of the ‘dogma of harmony’ in these fields. I then deploy these frameworks to examine some affective dimensions of place memory, sketching a strongly distributed conception of places as sometimes partly constituting the processes and activities of feeling and remembering. These approaches also offer useful perspectives on the problems of how to engage – politically and aesthetically – with difficult pasts and historically burdened heritage. In assessing artistic interventions in troubled places, we can seek responsibly to do justice to the past while fully embracing the dynamic and contested constructedness of our present emotions, memories, and activities.

This paper addresses relations between memory and imagery in expert sport in relation to visual or visuospatial perspective. Imagining, remembering, and moving potentially interact via related forms of episodic simulation, whether future- or past-directed. Sometimes I see myself engaged in action: many experts report switching between such external visual perspectives and an internal, 'own-eyes', or field perspective on their past or possible performance. Perspective in retrieval and in imagery may be flexible and multiple. I raise a range of topics for (...) empirical research on perspective and visualization. (shrink)

As a topic in the philosophy of psychology, dreaming is a fascinating, diverse, and severely underdeveloped area of study. The topic excites intense public interest in its own right, while also challenging our confidence that we know what the words “conscious” and “consciousness” mean. So dreaming should be at the forefront of our interdisciplinary investigations: theories of mind which fail to address the topic are incomplete. This chapter illustrates the tight links between conceptual and empirical issues by highlighting surprisingly deep (...) disagreements among leading dream scientists over what might seem basic aspects of their topic.

Perhaps the greatest impediment to a viable libertarianism is the provision of a satisfactory explanation of how actions that are undetermined by an agent's character can still be under the control of, or ‘up to’, the agent. The ‘luck problem’ has been most assiduously examined by Robert Kane who supplies a detailed account of how this problem can be resolved. Although Kane's theory is innovative, insightful, and more resourceful than most of his critics believe, it ultimately cannot account for the (...) type of control that moral responsibility and (ultimate) agency legitimately require.

This rich book, the best I’ve read in consciousness studies, offers more at each encounter. It was a brilliant idea to evaluate Hurlburt’s Descriptive Experience Sampling method through concrete sceptical enquiry by Schwitzgebel, whose role as open-minded but hard-nosed interlocutor makes the debate an intriguing, even gripping read. The radically different views about introspective reports held by the two authors are put to the test in the concrete context of ‘an examination, in unprecedented detail, of random moments of one person’s (...) experience ’.1 In addition to the ongoing central pursuit of the general question ‘Can we believe people’s reports about their inner experience?’, a raft of more specific issues are addressed as they arise in the sampling interviews. The book’s excellent organization, using in-text boxes linked by detailed crossreferencing into indexed threads, reinforces the thrilling sense that our access to the inner life of one person, ‘Melanie’, is bringing real progress on a number of fronts at once. Eric’s robust scepticism remains, but is tempered somewhat by being forced to confront the real constraints and opportunities of gathering information from a live subject. By the end of the project, he accepts that Russ’s ‘beep-andinterview methods’ deserve a central role in introspective science (p. (shrink)

A woman is listening to Sinatra before work. As she later describes it, ‘suddenly from nowhere I could hear my mother singing along to it … I was there again home again, hearing my mother … God knows why I should choose to remember that … then, to actually hear her and I had this image in my head … of being at home … with her singing away … like being transported back you know I got one of those (...) … like shivery feelings really suddenly’ (Anderson 2004, 9-10). An older couple, discussing their honeymoon forty years ago, each say that they can’t remember the show they saw, until through iterative, puzzled cross-cuing they finally get there – ‘Desert Song, that’s it’ (Harris et al 2011, 292). An elderly English veteran of a prisoner of war camp in Japan, finishing up morning tea with a young Japanese social scientist interested in reconciliation, suddenly calls out loudly - in Japanese - ‘stand to attention’. He stands to attention in front of her: like many of the men she interviews, he physically re-enacts fragments of that long-past world of the camp, bringing that absent past into this new present context with a visceral shock (Murakami 2001, 2012; Middleton & Brown 2005, 133-136).

In his contribution to the first issue of Memory Studies, Jeffrey Olick notes that despite “the mutual affirmations of psychologists who want more emphasis on the social and sociologists who want more emphasis on the cognitive”, in fact “actual crossdisciplinary research … has been much rarer than affirmations about its necessity and desirability” (2008: 27). The peculiar, contingent disciplinary divisions which structure our academic institutions create and enable many powerful intellectual cultures: but memory researchers are unusually aware that uneasy faultlines (...) and glaring gulfs lie in the uncertain zones between them. The processes of memory are simultaneously natural and cultural. But our difficulties in imagining even fragments of a genuinely integrated framework for understanding diverse memory-related phenomena do not arise from a simple ‘two-cultures’ problem: it’s not as if there are substantially unified visions of memory within either ‘the sciences’ or ‘the humanities’.

In the history of external information systems, the World Wide Web presents a significant change in terms of the accessibility and amount of available information. Constant access to various kinds of online information has consequences for the way we think, act and remember. Philosophers and cognitive scientists have recently started to examine the interactions between the human mind and the Web, mainly focussing on the way online information influences our biological memory systems. In this article, we use concepts from the (...) extended cognition and distributed cognition frameworks and from transactive memory theory to analyse the cognitive relations between humans and the Web. We first argue that while neither of these approaches neatly capture the nature of human-Web interactions, both offer useful concepts to describe aspects of such interactions. We then conceptualize relations between the Web and its users in terms of cognitive integration, arguing that most current Web applications are not deeply integrated and are better seen as a scaffold for memory and cognition. Some highly personalised applications accessed on wearable computing devices, however, may already have the capacity for deep integration. Finally, we draw out some of the epistemic implications of our cognitive analysis. (shrink)

Persons think. Bodies, time-slices of persons, and brains might also think. They have the necessary neural equipment. Thus, there seems to be more than one thinker in your chair. Critics assert that this is too many thinkers and that we should reject ontologies that allow more than one thinker in your chair. I argue that cases of multiple thinkers are innocuous and that there is not too much thinking. Rather, the thinking shared between, for example, persons and their bodies is (...) exactly what we should expect at the intersection of part sharing and the supervenience of the mental on the physical. I end by responding to the overcrowding objection, the personhood objection, the personal-pronoun reference problem and the epistemic objection. (shrink)

In ‘Evil is Still Evidence: Comments on Almeida’ Robert Bass presents three objections to the central argument (ENE) in my ‘Evil is Not Evidence’. The first objection is that ENE is invalid. According to the second objection, it is a consequence of ENE that there can be no evidence for or against a posteriori necessities. The third objection is that, contrary to ENE, the likelihood of certain necessary identities varies with the evidence we have for them. In this reply I (...) explain why ENE has exactly none of the implications described by Bass. I argue in the concluding section that there is a modal solution to the epistemological problems presented by ENE. (shrink)

I start with a brief assessment of the implications of Sterelny’s anti-individualist, anti-internalist apprentice learning model for a more historical and interdisciplinary cognitive science. In a selective response I then focus on two core features of his constructive account: collaboration and skill. While affirming the centrality of joint action and decision making, I raise some concerns about the fragility of the conditions under which collaborative cognition brings benefits. I then assess Sterelny’s view of skill acquisition and performance, which runs counter (...) to dominant theories that stress the automaticity of skill. I suggest that it may still overestimate the need for and ability of experts to decompose and represent the elements of their own practical knowledge. (shrink)

A case study in historical cognitive science, this paper addresses two claims made by radical proponents of new dynamical approaches. It queries their historical narrative, which sees embodied, situated cognition as correcting an individualist, atemporal framework originating in Descartes. In fact, new Descartes scholarship shows that 17th-century animal spirits neurophysiology realized a recognizably distributed model of memory; explicit representations are patterns of spirit flow, and memory traces are changes left by experience in connections between brain pores. This historical sketch supports (...) the second dynamicist claim, that connectionists' stress on the cognitive importance of pattern-recreation needs supplementing by dynamicists' real-time focus and attention to the active roles of body and environment. Animal spirits theory exhibits just the 'continuous reciprocal causation' between brain, body, and environment which Andy Clark sees as dynamicism's central contribution, and allows for the embedding of brains in culture as well as the physical world.

Many philosophers argue that the right of self-determination confers to states a right to exclude would-be migrants. Drawing on the case of anti-colonial struggles of the 20th century, I argue that self-determination should be thought of as fundamentally a claim against intergroup hierarchy. This means that self-determination only grants a right to exclude in cases where immigration poses a genuine oppressive threat. Cases involving immigration into wealthy and powerful states rarely meet this criterion, and so talk of self-determination as grounding (...) a right to exclude in such cases is misguided. (shrink)

We argue that Maclaurin and Dyke's recent critique of non-naturalistic metaphysics suffers from difficulties analogous to those that caused trouble for earlier positivist critiques of metaphysics. Maclaurin and Dyke say that a theory is naturalistic iff it has observable consequences. Depending on the details of this criterion, either no theory counts as naturalistic or every theory does.

English instrument-maker, experimentalist, and natural philosopher who made key contributions in a wide range of areas including physiology, geology, and mechanics. Born on the Isle of Wight, Hooke showed early aptitude with the design of mechanical toys. At Westminster School he learnt mathematics and geometry, and at Christ Church, Oxford, he joined a remarkable group of natural philosophers working before the Restoration on physiological and physical topics (Frank 1980). Much of Hooke’s career was driven by financial uncertainty. As an employee, (...) working firstly with Robert Boyle and then as curator of experiments at the new Royal Society from 1662 to 1677, Hooke’s status as a professional in a society of gentlemen natural philosophers was problematic. He was continually concerned to establish his credibility, and his defences of ownership of his ideas were often vitriolic. (shrink)

Assuming divine command theory is true, there are no moral limits on the commands God can issue. Nevertheless there are no possible worlds in which divine command theory is true and God commands cruelty for its own sake or the sacrifice of ten-year-olds in a gruesome ritual, or anything of the kind. The main conclusion of the argument is that God cannot command the morally horrible not because of God's moral perfection or God's lack of power, of God's kindness, etc., (...) but because commanding the morally horrible entails a contradiction. I show that the argument is an instance of a valid and uncontroversial counterfactual sequent. Divine command theory entails that there are commands that even an omnipotent and morally unconstrained being cannot issue. (shrink)

Descartes was born in La Haye (now Descartes) in Touraine and educated at the Jesuit college of La Fleche` in Anjou. Descartes’modern reputation as a rationalistic armchair philosopher, whose mind–body dualism is the source of damaging divisions between psychology and the life sciences, is almost entirely undeserved. Some 90% of his surviving correspondence is on mathematics and scientific matters, from acoustics and hydrostatics to chemistry and the practical problems of constructing scientific instruments. Descartes was just as interested in the motions (...) of matter as in the supernatural soul, and he advised against spending too much time on metaphysical inquiries which neglect imagination and the senses. After meeting the Dutch engineer Isaac Beeckman in 1618, Descartes became committed to a systematically ‘mechanical’account of nature. This involved explaining all natural processes in terms of interactions between microscopic material bodies in motion. Descartes modelled his physics and cosmology on the behaviour of fluids, which also have a distinctive and central role in his physiology: the key processes for natural philosophical investigation are the circulation and mutual displacement of constrained bodies, rather than the isolated collisions of atoms in a void. Descartes settled in Holland in 1628, and commenced an ambitious programme of physiological research. In 1630 he was ‘studying chemistry and anatomy simultaneously’, and in late 1632 he was ‘dissecting the heads of various animals’, in order to ‘explain what imagination, memory, etc. consist in’. By late 1633 Descartes had almost completed L’homme, the Treatise on Man; but he abandoned plans to publish it along with a work on matter theory and optics which relied on Copernican cosmology, after he heard of the condemnation of Galileo. L’homme was published posthumously in 1662 (Latin) and 1664 (French); not until 1972 was it fully translated into English. L’homme draws on many (mostly unnamed) Renaissance medical writers, and covers, firstly, a range of traditional physiological topics, such as digestion and respiration.. (shrink)

Memory is a set of cognitive capacities by which humans and other animals retain information and reconstruct past experiences, usually for present purposes. Philosophical investigation into memory is in part continuous with the development of cognitive scientific theories, but includes related inquiries into metaphysics and personal identity.
