Rationale: Deep brain stimulation (DBS) of the hippocampus is proposed for enhancement of memory impaired by injury or disease. Many pre-clinical DBS paradigms can be addressed in epilepsy patients undergoing intracranial monitoring for seizure localization, since they already have electrodes implanted in brain areas of interest. Even though epilepsy is usually not a memory disorder targeted by DBS, the studies can nevertheless model other memory-impacting disorders, such as Traumatic Brain Injury (TBI). Methods: Human patients undergoing Phase II invasive monitoring for (...) intractable epilepsy were implanted with depth electrodes capable of recording neurophysiological signals. Subjects performed a delayed-match-to-sample (DMS) memory task while hippocampal ensembles from CA1 and CA3 cell layers were recorded to estimate a multi-input, multi-output (MIMO) model of CA3-to-CA1 neural encoding and a memory decoding model (MDM) to decode memory information from CA3 and CA1 neuronal signals. After model estimation, subjects again performed the DMS task while either MIMO-based or MDM-based patterned stimulation was delivered to CA1 electrode sites during the encoding phase of the DMS trials. Each subject was sorted (post hoc) by prior experience of repeated and/or mild-to-moderate brain injury (RMBI), TBI, or no history (control) and scored for percentage successful delayed recognition (DR) recall on stimulated vs. non-stimulated DMS trials. The subject’s medical history was unknown to the experimenters until after individual subject memory retention results were scored. Results: When examined compared to control subjects, both TBI and RMBI subjects showed increased memory retention in response to both MIMO and MDM-based hippocampal stimulation. Furthermore, effects of stimulation were also greater in subjects who were evaluated as having pre-existing mild-to-moderate memory impairment. Conclusion: These results show that hippocampal stimulation for memory facilitation was more beneficial for subjects who had previously suffered a brain injury (other than epilepsy), compared to control (epilepsy) subjects who had not suffered a brain injury. This study demonstrates that the epilepsy/intracranial recording model can be extended to test the ability of DBS to restore memory function in subjects who previously suffered a brain injury other than epilepsy, and support further investigation into the beneficial effect of DBS in TBI patients.

In Mind and World, John McDowell argues against the view that perceptual representation is non-conceptual. The central worry is that this view cannot offer any reasonable account of how perception bears rationally upon belief. I argue that this worry, though sensible, can be met, if we are clear that perceptual representation is, though non-conceptual, still in some sense 'assertoric': Perception, like belief, represents things as being thus and so.

Many philosophers nowadays believe Frege was right about belief, but wrong about language: The contents of beliefs need to be individuated more finely than in terms of Russellian propositions, but the contents of utterances do not. I argue that this 'hybrid view' cannot offer no reasonable account of how communication transfers knowledge from one speaker to another and that, to do so, we must insist that understanding depends upon more than just getting the references of terms right.

Frege's development of the theory of arithmetic in his Grundgesetze der Arithmetik has long been ignored, since the formal theory of the Grundgesetze is inconsistent. His derivations of the axioms of arithmetic from what is known as Hume's Principle do not, however, depend upon that axiom of the system--Axiom V--which is responsible for the inconsistency. On the contrary, Frege's proofs constitute a derivation of axioms for arithmetic from Hume's Principle, in (axiomatic) second-order logic. Moreover, though Frege does prove each of (...) the now standard Dedekind-Peano axioms, his proofs are devoted primarily to the derivation of his own axioms for arithmetic, which are somewhat different (though of course equivalent). These axioms, which may be yet more intuitive than the Dedekind-Peano axioms, may be taken to be "The Basic Laws of Cardinal Number", as Frege understood them. Though the axioms of arithmetic have been known to be derivable from Hume's Principle for about ten years now, it has not been widely recognized that Frege himself showed them so to be; nor has it been known that Frege made use of any axiomatization for arithmetic whatsoever. Grundgesetze is thus a work of much greater significance than has often been thought. First, Frege's use of the inconsistent Axiom V may invalidate certain of his claims regarding the philosophical significance of his work (viz., the establishment of Logicism), but it should not be allowed to obscure his mathematical accomplishments and his contribution to our understanding of arithmetic. Second, Frege's knowledge that arithmetic is derivable from Hume's Principle raises important sorts of questions about his philosophy of arithmetic. For example, "Why did Frege not simply abandon Axiom V and take Hume's Principle as an axiom?". (shrink)

I here investigate the sense in which diagonalization allows one to construct sentences that are self-referential. Truly self-referential sentences cannot be constructed in the standard language of arithmetic: There is a simple theory of truth that is intuitively inconsistent but is consistent with Peano arithmetic, as standardly formulated. True self-reference is possible only if we expand the language to include function-symbols for all primitive recursive functions. This language is therefore the natural setting for investigations of self-reference.

Frege, famously, held that there is a close connection between our concept of cardinal number and the notion of one-one correspondence, a connection enshrined in Hume's Principle. Husserl, and later Parsons, objected that there is no such close connection, that our most primitive conception of cardinality arises from our grasp of the practice of counting. Some empirical work on children's development of a concept of number has sometimes been thought to point in the same direction. I argue, however, that Frege (...) was close to right, that our concept of cardinal number is closely connected with a notion like that of one-one correspondence, a more primitive notion we might call just as many.

One of the earliest discussions of the so-called 'bad company' objection to Neo-Fregeanism, I show that the consistency of an arbitrary second-order 'contextual definition' (nowadays known as an 'abstraction principle' is recursively undecidable. I go on to suggest that an acceptable such principle should satisfy a condition nowadays known as 'stablity'.

Syntactic Reductionism, as understood here, is the view that the ‘logical forms’ of sentences in which reference to abstract objects appears to be made are misleading so that, on analysis, we can see that no expressions which even purport to refer to abstract objects are present in such sentences. After exploring the motivation for such a view, and arguing that no previous argument against it succeeds, sentences involving generalized quantifiers, such as ‘most’, are examined. It is then argued, on this (...) basis, that Syntactic Reductionism is untenable. (shrink)

This article offers an overview of the various formulations of "jihad" during the first six Islamic centuries (7th-13th CE), showing them to be embedded in particular socio-historical contexts. If the essential significance of "jihad" as righteous cause (i.e., action for the sake of a moral order) is shown to have been variously altered according to the needs and conditions of the Muslim community, significant possibilities arise for a contemporary understanding of "jihad" that is relevant to the needs and circumstances of (...) the Muslim community today. Some features of the "jihad" tradition, although specific to a particular period and with little relevance today, continue to inform the current discussion on "jihad." Discussion of the "jihad" tradition, then, should take care to distinguish the historically incidental features of the tradition from those with an enduring relevancy. By doing so, the "jihad" tradition will be able to contribute to discussions on the relation of religion to the public order and political organization, even those not limited to Islam. (shrink)

This paper dates from about 1994: I rediscovered it on my hard drive in the spring of 2002. It represents an early attempt to explore the connections between the Julius Caesar problem and Frege's attitude towards Basic Law V. Most of the issues discussed here are ones treated rather differently in my more recent papers "The Julius Caesar Objection" and "Grundgesetze der Arithmetik I 10". But the treatment here is more accessible, in many ways, providing more context and a better (...) sense of how this issue relates to broader issues in Frege's philosophy. (shrink)

Frege's intention in section 31 of Grundgesetze is to show that every well-formed expression in his formal system denotes. But it has been obscure why he wants to do this and how he intends to do it. It is argued here that, in large part, Frege's purpose is to show that the smooth breathing, from which names of value-ranges are formed, denotes; that his proof that his other primitive expressions denote is sound and anticipates Tarski's theory of truth; and that (...) the proof that the smooth breathing denotes, while flawed, rests upon an idea now familiar from the completeness proof for first-order logic. The main work of the paper consists in defending a new understanding of the semantics Frege offers for the quantifiers: one which is objectual, but which does not make use of the notion of an assignment to a free variable. (shrink)

In section 10 of Grundgesetze, Frege confronts an indeterm inacy left by his stipulations regarding his ‘smooth breathing’, from which names of valueranges are formed. Though there has been much discussion of his arguments, it remains unclear what this indeterminacy is; why it bothers Frege; and how he proposes to respond to it. The present paper attempts to answer these questions by reading section 10 as preparatory for the (fallacious) proof, given in section 31, that every expression of Frege's formal (...) language denotes.

John MacFarlane has made relativism popular again. Focusing just on his original discussion, I argue that the data he uses to motivate the position do not, in fact, motivatie it at all. Many of the points made here have since been made, independently, by Hermann Cappelen and John Hawthorne, in their book Relativism and Monadic Truth.

This paper offers a historical analysis of contemporary practices of shopping for vegetables in the highly dynamic context of urban Hanoi during the period from 1975 to 2014. Focusing on everyday shopping practices from a food safety perspective, we assess the extent to which the policy-enforced process of supermarketization has proven to be an engine of change in daily vegetable purchasing while improving food safety. In depicting transitions in shopping practices, we combine a social practices approach with historical analysis. Providing (...) a historical analysis of a broad and complex spectrum of everyday practices of purchasing fresh vegetables, we identify the key drivers of change. We discuss different modalities of shopping and demonstrate that no single retail modernization format can be said to exist. Rather than contrasting an idealized supermarket model with the traditional modalities of food shopping, we offer a varied, more diverse set of shopping practices that displays different strategies for coping with food safety issues. When discussed from a historical perspective, food practices are shown to be highly dynamic, being constantly reinvented and reconfigured by consumers who use their established skills, routines, and social networks to sometimes resist top-down enforced supermarketization while developing the coping strategies that best suit their local circumstances.

Sufism - spiritual practice, intellectual discipline, literary tradition, and social institutionhas played an integral role in the moral formation of Muslim society. Its aspiration toward a universal kindness to all creatures beyond the requirements of Islamic law has added a distinctly hypernomian dimension to the moral vision of Islam, as evidenced in a wide range of Sufi literature. The universal perspective of Sufism, fully rooted in Islamic revelation, yields a lived (and not just studied) ethics with the potential to view (...) and embrace all creatures through a single ethical vision, regardless of religious or other affiliation. This side of Islam, both acknowledging and surpassing the outlook of the legal heritage, offers important insight into understanding the nature of Muslim society as both Islamic and metaIslamic in religious orientation. Sufism, still significant in today's Islamic world, thus offers important material for locating Islam as part of an international order with principles and standards that resonate deeply with the moral vision of Islam itself.

A reply to Byrne and Thau's criticisms of "The Sense of Communiction".

Respiratory rhythms sustain biological life, governing the homeostatic exchange of oxygen and carbon dioxide. Until recently, however, the influence of breathing on the brain has largely been overlooked. Yet new evidence demonstrates that the act of breathing exerts a substantive, rhythmic influence on perception, emotion, and cognition, largely through the direct modulation of neural oscillations. Here, we synthesize these findings to motivate a new predictive coding model of respiratory brain coupling, in which breathing rhythmically modulates both local and global neural (...) gain, to optimize cognitive and affective processing. Our model further explains how respiratory rhythms interact with the topology of the functional connectome, and we highlight key implications for the computational psychiatry of disordered respiratory and interoceptive inference.

This book is a defense of political liberalism as a feminist liberalism. A novel and restrictive account of public reason is defended. Then it is argued that political liberalism's core commitments restrict reasonable conceptions of justice to those that secure genuine, substantive equality for women and other marginalized groups.

Zeitgeist Literature is offered here as a term with great potential as a conceptual tool for analyzing literature that responds to the moment in which it was written. Such literature chronicles the social and political life of the current moment, its trends and moods, and the mysterious forces that dictate tastes, manners, feelings, and actions of the collective.

Roots are good to think with indeed most of us use them as a metaphor every day. A root can signify the hiddenness of our beginnings, or, in its bifurcating structure, the various possibilities in the life of an individual or a collective. This book looks at rootedness as a metaphor for the genealogical origins of people and their attachment to place and how this metaphor transformed so rapidly in twentieth-century Europe. Christy Wampole s case study is France, with its (...) contradictory legacies of Enlightenment universalism, anti-Semitism, and colonialism. At one time, French nationalist rhetoric portrayed the Jews as unrooted and thus unrighteous people. After the two world wars, the root metaphor figured in the new French philosophy (notably Deleuze and Guattari). And recently, Caribbean thinkers in Haiti, Guadeloupe, and Martinique have debated whether their roots were in Africa, France, the Caribbean, or in some pan-national network that could not be identified on a map. Walpole argues that while the metaphor was perhaps once useful in the establishment of communities and identities, that usefulness has expired. The longer we remain attached to the figure of rootedness, the more discord it sows. Giving up on the metaphor of rootedness, Wampole urges, allows us to see at last that we are in fact unbound by the land we inhabit.". (shrink)

While Christian Democratic parties in several Western European countries are often said to be in crisis, the European People's Party holds the largest parliamentary group in the European Parliament since 1999. This paradox relies on the specificity of the different 'national' electoral logics on the one hand and the realisation of a long-term 'European' majority strategy on the other hand. The alliance with Conservatives and Conservative parties has to overcome an absolute electoral decline in 'old' EU countries and a relative (...) decline through the accession of 'new' member states without Christian Democratic parties. The EPP majority strategy is realised through various ways : the key position of the transnational party and party group, the role of political leadership, the way of decision making, the co-operation with side-organisations, the problem-solving of ideological conflicts, etc. Our analysis proves how the majority strategy of the European Christian Democrats realises its ultimate 'survival strategy' despite several nationalparty crises.

"To what extent can legal decisions be objective and fair, and how far does government depend on the law for its legitimacy? This concise analytical book examines the theory of both individual and political justice, concluding that many modern legal philosophers have undermined the prestige of the law by exaggerated claims in its defence. This is a basic book in jurisprudence"--Jacket.

''Biodiversity'' is all to often used as a buzz-word, with no clearly defined meaning, let alone a strict procedure to measure it. This article proposes a logical procedure, based on a similar approach in socio-economics (to measure income inequality). Every element in our logical procedure is known. Bringing it all together as presented is new, as far as we know.

This groundbreaking book is the first to provide a critical overview of the relationship between contemporary ceramics and curatorial practice in museum culture. Ceramic objects form a major part of museum collections, with connections to anthropology, archaeology and other disciplines that engage with the cultural and social history of humankind. In recent years museums have provided the impetus for cutting-edge artistic practice, either as a response to particular collections, or as part of exhibitions. But the question of how museums have (...) staged contemporary ceramics and how ceramic artists respond to museum collections has not been the subject of published research to date. This book examines how ceramic artists have, over the last decade, begun to animate museum collections in new ways, and reflects on the impact that these new initiatives have had in the broad context of visual culture. Ceramics in the Expanded Field is the culmination of a three-year AHRC funded project, and reflects its major findings. It brings together leading international voices in the field of ceramics, research undertaken throughout the project and papers delivered at the concluding conference. By examining the benefits and constraints of interventions and the dialogue between ceramics and museological practice, this book will bring focus to an area of museology that has not yet been theorized, and will contribute to policy debates and art practice.

In The Varieties of Reference, Gareth Evans argues that the content of perceptual experience is nonconceptual, in a sense I shall explain momentarily. More recently, in his book Mind and World, John McDowell has argued that the reasons Evans gives for this claim are not compelling and, moreover, that Evans’s view is a version of “the Myth of the Given”: More precisely, Evans’s view is alleged to suffer from the same sorts of problems that plague sense-datum theories of perception. In (...) particular, McDowell argues that perceptual experience must be within “the space of reasons,” that perception must be able to give us reasons for, that is, to justify, our beliefs about the world: And, according to him, no state that does not have conceptual content can be a reason for a belief. Now, there are many ways in which Evans’s basic idea, that perceptual content is nonconceptual, might be developed; some of these, I shall argue, would be vulnerable to the objections McDowell brings against him. But I shall also argue that there is a way of developing it that is not vulnerable to these objections. (shrink)

Philosopher Kings? The Adjudication of Conflicting Human Rights and Social Values, by George C. Christie, examines the attempts by courts to sort out conflicts involving freedom of expression, including religious expression, on the one hand, and rights to privacy and other important social values on the other. It approaches the subject from a comparative perspective, using principally cases decided by European and United States courts. A significant part of this book analyzes conflicts between freedom of expression and the right to (...) privacy. In a world in which, freedom of expression and privacy are said to be of equal value, the book explores whether it is possible to develop, through case-by-case adjudication, a legal regime which can give clear direction as to what expression is or is not permitted. Otherwise, if such a regime proves impossible, in the guise of recognizing the equal value of expression and privacy, privacy may become de facto the preferred value. (shrink)

It is common to distinguish between “holist” and “reductionist” views of brain function, where the former envisions the brain as functioning as an indivisible unit and the latter as a collection of distinct units that serve different functions. Opposing reductionism, a number of researchers have pointed out that cortical network architecture does not respect functional boundaries, and the neuroanatomist V. Braitenberg proposed to understand the cerebral cortex as a “great mixing machine” of neuronal activity from sensory inputs, motor commands, and (...) intrinsically generated processes. In this paper, we offer a contextualization of Braitenberg’s point, and we review evidence for the interactions of neuronal activity from multiple sensory inputs and intrinsic neuronal processes in the cerebral cortex. We focus on new insights from studies on audiovisual interactions and on the influence of respiration on brain functions, which do not seem to align well with “reductionist” views of areal functional boundaries. Instead, they indicate that functional boundaries are fuzzy and context dependent. In addition, we discuss the relevance of the influence of sensory, proprioceptive, and interoceptive signals on cortical activity for understanding brain-body interactions, highlight some of the consequences of these new insights for debates on embodied cognition, and offer some suggestions for future studies.

John Etchemendy has argued that it is but "a fortuitous accident" that Tarski's work on truth has any signifance at all for semantics. I argue, in response, that Etchemendy and others, such as Scott Soames and Hilary Putnam, have been misled by Tarski's emphasis on definitions of truth rather than theories of truth and that, once we appreciate how Tarski understood the relation between these, we can answer Etchemendy's implicit and explicit criticisms of neo-Davidsonian semantics.

A close look at Frege's proof in "Foundations of Arithmetic" that every number has a successor. The examination reveals a surprising gap in the proof, one that Frege would later fill in "Basic Laws of Arithmetic".

Is a feminist political liberalism possible? Political liberalism’s regard for a wide range of comprehensive doctrines as reasonable makes some feminists skeptical of its ability to address sex inequality. Indeed, some feminists claim that political liberalism maintains its position as a political liberalism at the expense of securing substantive equality for women. We claim that political liberalism’s core commitments actually restrict all reasonable political conceptions of justice to those that secure genuine substantive equality for all, including women and other marginalized (...) groups. In particular, we argue that political liberalism’s criterion of reciprocity limits reasonable political conceptions of justice to those that eliminate social conditions of domination and subordination relevant to reasonable democratic deliberation among equal citizens and that the criterion of reciprocity requires the social conditions necessary for recognition respect among persons as equal citizens. As a result, we maintain that the criterion of reciprocity limits reasonable political conceptions of justice to those that provide genuine equality for women along various dimensions of social life central to equal citizenship.
