The author argues that the core of Hume’s Academic skepticism lies in his commitment to an external world and objective causal powers that are cognitively opaque to human understanding. Three central topics of Hume’s theory of the understanding are discussed—the existence of absolute space, the existence of a world external to our senses, and the existence of objective causal powers. In each case, Hume draws a Pyrrhonian opposition between judgments based on his “Copy Principle” and the “fictions” or “illusions” formed (...) through association of ideas. While he suspends judgment concerning the existence of absolute space, he argues that the association-based beliefs in an external world and objective causal powers are necessary for human life and indispensible in science. In adopting such beliefs about external reality, while at the same time denying their intelligibility, Hume was following ancient Academic skepticism. (shrink)

By utilizing new information from both clinical and experimental (lesion, electrophysiological, and gene-activation) studies with animals, the anatomy underlying anterograde amnesia has been reformulated. The distinction between temporal lobe and diencephalic amnesia is of limited value in that a common feature of anterograde amnesia is damage to part of an comprising the hippocampus, the fornix, the mamillary bodies, and the anterior thalamic nuclei. This view, which can be traced back to Delay and Brion (1969), differs from other recent models in (...) placing critical importance on the efferents from the hippocampus via the fornix to the diencephalon. These are necessary for the encoding and, hence, the effective subsequent recall of episodic memory. An additional feature of this hippocampalanterior thalamic and the perirhinal–medial dorsal thalamic systems are compromised, leading to severe deficits in both recall and recognition. (shrink)

Scientific authorship has become a contested terrain in contemporary science. Based on a survey of authors across fields, we measure the likelihood of specialist authors : people who only made specialized contributions, such as data, materials, or funding; and “nonauthor collaborators” : those who did significant work on the project but do not appear as authors, across different research contexts, including field, size of the project team, commercial orientation, impact of publication, and organization of the collaboration. We find that guest (...) and ghost authors are common, with about one-third of publications having at least one specialist author and over half having at least one nonauthor collaborator. We see significant cross-field variations in both overall rates and types of specialist authors and nonauthor collaborators. We find there are generally fewer specialist authors among highly cited papers and more graduate student nonauthor collaborators in single location projects. The results suggest authorship practices vary across fields, and by project characteristics, complicating the use of authorship lists as a basis for evaluation. We discuss implications of these findings for interpreting author lists in the context of science policy. (shrink)

Numbers and other mathematical objects are exceptional in having no locations in space or time or relations of cause and effect. This makes it difficult to account for the possibility of the knowledge of such objects, leading many philosophers to embrace nominalism, the doctrine that there are no such objects, and to embark on ambitious projects for interpreting mathematics so as to preserve the subject while eliminating its objects. This book cuts through a host of technicalities that have obscured previous (...) discussions of these projects, and presents clear, concise accounts of a dozen strategies for nominalistic interpretation of mathematics, thus equipping the reader to evaluate each and to compare different ones. The authors also offer critical discussion, rare in the literature, of the aims and claims of nominalistic interpretation, suggesting that it is significant in a very different way from that usually assumed.

The most important distinctively American contribution to philosophy is the pragmatist tradition. In this short, lucid, and completely convincing exposition, Professor John P. Murphy begins by exploring the roots of this tradition as found in the work of Peirce, James, and Dewey, demonstrating its power and originality. Historians of philosophy will appreciate the insight Murphy brings to these figures, but the special value of this book lies in his discussion of how the pragmatist spirit has flowered in contemporary philosophy (...) in the work of Quine, Rorty, and Davidson.Throughout, Murphy emphasizes the logic and structure of the views held by these six philosophers and what it is they have in common that makes their work especially “pragmatist.” There is no better introduction to this historical tradition and perhaps no better way into the philosophies of the contemporaries whom Murphy discusses.Interest in pragmatist ideas is undergoing a revival at present, and this book shows us why. It will be of interest to both historians of philosophy and students of contemporary philosophy. (shrink)

While we are commonly told that the distinctive method of mathematics is rigorous proof, and that the special topic of mathematics is abstract structure, there has been no agreement among mathematicians, logicians, or philosophers as to just what either of these assertions means. John P. Burgess clarifies the nature of mathematical rigor and of mathematical structure, and above all of the relation between the two, taking into account some of the latest developments in mathematics, including the rise of experimental (...) mathematics on the one hand and computerized formal proofs on the other hand. Along the way, a great many historical developments in mathematics, philosophy, and logic are surveyed. Yet very little in the way of background knowledge on the part of the reader is presupposed.

The debate over whether brain death is death has focused on whether individuals who have sustained total brain failure have satisfied the biological definition of death as “the irreversible loss of the integration of the organism as a whole.” In this paper, I argue that what it means for an organism to be integrated “as a whole” is undefined and vague in the views of those who attempt to define death as the irreversible loss of the integration of the organism (...) as a whole. I show how what it means for a living thing to be integrated as a whole depends on the sortal concept by which it is identified. Since interests, values, and ontological considerations besides strictly biological ones affect the concepts by which we individuate and identify living things, those non-biological considerations have a bearing on what it means for a particular kind of living thing to exist as a whole and thus what it means for one of us to die. Even if our bodies may remain organically integrated in some sense despite total brain failure, this fact should not lead us to reject brain death as death. Artificially sustained brain-dead human bodies are not human beings, but the remains of them. While such bodies may be alive in some sense, they are not human beings or human persons. They are not one of us. (shrink)

In this paper Sullins argues that in certain circumstances robots can be seen as real moral agents. A distinction is made between persons and moral agents such that, it is not necessary for a robot to have personhood in order to be a moral agent. I detail three requirements for a robot to be seen as a moral agent. The first is achieved when the robot is significantly autonomous from any programmers or operators of the machine. The second is when (...) one can analyze or explain the robot's behavior only by ascribing to it some predisposition or 'intention' to do good or harm. And finally, robot moral agency requires the robot to behave in a way that shows and understanding of responsibility to some other moral agent. Robots with all of these criteria will have moral rights as well as responsibilities regardless of their status as persons. (shrink)

One hundred years ago, in his lecture Science as a Vocation, Max Weber prefigured a transition from science as a calling to science as bureaucratically organized work. He argued that a calling for science is critical for sustaining scientific work. Using Weber’s arguments for science as a vocation as a lens, in this paper, we discuss whether a calling for science may become difficult to maintain in increasingly bureaucratized scientific work—and also whether such a calling is necessary for the advance (...) of science. We present empirical evidence for this bureaucratization of scientific work and further develop Weber’s discussion of science by contrasting it with the views of other theorists of science and innovation. Finally, we discuss the implications of these theories, develop a set of policy recommendations, and outline a research agenda designed to develop science policies and a sociology of science that match this shift from vocation to bureaucracy in scientific work.

This volume attempts to show why ontology matters for a proper grasp of issues in bioethics. -/- Contemporary discussions on bioethics often focus on seeking solutions for a wide range of issues that revolve around persons. The issues in question are multi-layered, involving such diverse aspects as the metaphysical/ontological, personal, medical, moral, legal, cultural, social, political, religious, and environmental. In navigating through such a complex web of issues, it has been said that the central problems philosophers and bioethicists face are (...) ethical in nature. In this regard, biomedical sciences and technological breakthroughs take a leading role in terms of shaping the sorts of questions that give rise to ethical problems. For example, is it ethical to keep terminally ill patients alive on dialysis machines or artificial ventilators? Is it ethical to take someone’s vital organs upon death and transplant them into another person’s body without any prior consent from a deceased person? Reproductive techniques also raise complicated ethical issues involving in vitro fertilization, contraceptives, prenatal testing, abortions, and genetic enhancements. Moreover, biomedical issues raise ethical problems in regards to research on human subjects, stem cell research, and enhancement biotechnology. The beginning and end of life issues bring up their own complicated ethical conundrums involving, among other things, terminating life support and euthanasia. -/- This book approaches such complex bioethical questions by engaging in ground-level debates about the ontology of persons. This is a non-negotiable first step in taking steps forward in seeking a plausible solution(s) for the complex ethical problems in bioethics. Although the contributors in this book advance their arguments in their own ways, they all agree on one crucial methodological point: the importance of taking the ontology of persons for bioethics seriously. This is the spirit that brings the contributors of this book together as they seek to build their case(s) concerning the nature of persons. (shrink)

Philosophical Logic is a clear and concise critical survey of nonclassical logics of philosophical interest written by one of the world's leading authorities on the subject. After giving an overview of classical logic, John Burgess introduces five central branches of nonclassical logic, focusing on the sometimes problematic relationship between formal apparatus and intuitive motivation. Requiring minimal background and arranged to make the more technical material optional, the book offers a choice between an overview and in-depth study, and it balances (...) the philosophical and technical aspects of the subject.The book emphasizes the relationship between models and the traditional goal of logic, the evaluation of arguments, and critically examines apparatus and assumptions that often are taken for granted. Philosophical Logic provides an unusually thorough treatment of conditional logic, unifying probabilistic and model-theoretic approaches. It underscores the variety of approaches that have been taken to relevantistic and related logics, and it stresses the problem of connecting formal systems to the motivating ideas behind intuitionistic mathematics. Each chapter ends with a brief guide to further reading.Philosophical Logic addresses students new to logic, philosophers working in other areas, and specialists in logic, providing both a sophisticated introduction and a new synthesis.

The great logician Gottlob Frege attempted to provide a purely logical foundation for mathematics. His system collapsed when Bertrand Russell discovered a contradiction in it. Thereafter, mathematicians and logicians, beginning with Russell himself, turned in other directions to look for a framework for modern abstract mathematics. Over the past couple of decades, however, logicians and philosophers have discovered that much more is salvageable from the rubble of Frege's system than had previously been assumed. A variety of repaired systems have been (...) proposed, each a consistent theory permitting the development of a significant portion of mathematics. This book surveys the assortment of methods put forth for fixing Frege's system, in an attempt to determine just how much of mathematics can be reconstructed in each. John Burgess considers every proposed fix, each with its distinctive philosophical advantages and drawbacks. These systems range from those barely able to reconstruct the rudiments of arithmetic to those that go well beyond the generally accepted axioms of set theory into the speculative realm of large cardinals. For the most part, Burgess finds that attempts to fix Frege do less than advertised to revive his system. This book will be the benchmark against which future analyses of the revival of Frege will be measured. (shrink)

Critics of organ donation after circulatory death (DCD) argue that, even if donors are past the point of autoresuscitation, they have not satisfied the “irreversibility” requirement in the circulatory and respiratory criteria for determining death, since their circulation and respiration could be artificially restored. Thus, removing their vital organs violates the “dead-donor” rule. I defend DCD donation against this criticism. I argue that practical medical-ethical considerations, including respect for do-not-resuscitate orders, support interpreting “irreversibility” to mean permanent cessation of circulation and (...) respiration. Assuming a consciousness-related formulation of human death, I then argue that the loss of circulation and respiration is significant, because it leads to the permanent loss of consciousness and thus to the death of the human person. The DNR request by an organ donor should thus be interpreted to mean “do not restore to consciousness.” Finally, I respond to an objection that if “irreversibility” has a medical-ethical meaning, it would entail the absurd possibility that one of two individuals in the same physical state could be alive and the other dead—an implication that some think is inconsistent with understanding death as an objective biological state of the organism. I argue that advances in medical technology have created phenomena that challenge the assumption that human death can be understood in strictly biological terms. I argue that ethical and ontological considerations about our nature bear on the definition and determination of death and thus on the permissibility of DCD. (shrink)

Two strategies used to uncover neural systems for episodic-like memory in animals are discussed: (i) an attribute of episodic memory (what? when? where?) is examined in order to reveal the neuronal interactions supporting that component of memory; and (ii) the connections of a structure thought to be central to episodic memory in humans are studied at a level of detail not feasible in humans. By focusing on spatial memory (where?) and the hippocampus, it has proved possible to bring the strategies (...) together. A review of lesion, disconnection and immediate early-gene studies in animals reveals the importance of interactions between the hippocampus and specific nuclei in the diencephalon (most notably the anterior thalamic nuclei) for spatial memory. Other parts of this extended hippocampal system include the mammillary bodies and the posterior cingulate (retrosplenial) cortex. Furthermore, by combining lesion and immediate early-gene studies it is possible to show how the loss of one component structure or tract can influence the remaining regions in this group of structures. The validity of this convergent approach is supported by new findings showing that the same set of regions is implicated in anterograde amnesia in humans. (shrink)

The integrative memory model contains multiple subsystems. In this commentary, the processes within these subsystems are questioned. First, the assumption that familiarity largely reflects perceptual fluency is examined. Next, the distinction between “process” and “representational” models of temporal lobe function is challenged. Finally, the “relational representation core system”, which is central to the model, is especially sketchy. Here, I highlight key questions to be addressed in order to understand this system's role in trace formation.

The goal of our target article was to review a number of emerging facts about the effects of limbic damage on memory in humans and animals, and about divisions within recognition memory in humans. We then argued that this information can be synthesized to produce a new view of the substrates of episodic memory. The key pathway in this system is from the hippocampus to the anterior thalamic nuclei. There seems to be a general agreement that the importance of this (...) pathway has previously been underestimated and that it warrants further study. At the same time, a number of key questions remain. These concern the relationship of this system to another temporal-lobe/diencephalic system that contributes to recognition, and the relationship of these systems to prefrontal cortex activity.

Highlighting previously neglected democratic strains in Machiavelli's major writings, McCormick excavates institutions through which the common people of ancient, medieval, and Renaissance republics constrained the power of wealthy citizens and public magistrates, and he imagines how such institutions might be revived today.

Darwinism, Democracy, and Race examines the development and defence of an argument that arose at the boundary between anthropology and evolutionary biology in twentieth-century America. In its fully articulated form, this argument simultaneously discredited scientific racism and defended free human agency in Darwinian terms. The volume is timely because it gives readers a key to assessing contemporary debates about the biology of race. By working across disciplinary lines, the book's focal figures--the anthropologist Franz Boas, the cultural anthropologist Alfred Kroeber, the (...) geneticist Theodosius Dobzhansky, and the physical anthropologist Sherwood Washburn--found increasingly persuasive ways of cutting between genetic determinist and social constructionist views of race by grounding Boas's racially egalitarian, culturally relativistic, and democratically pluralistic ethic in a distinctive version of the genetic theory of natural selection. Collaborators in making and defending this argument included Ashley Montagu, Stephen Jay Gould, and Richard Lewontin. Darwinism, Democracy, and Race will appeal to advanced undergraduates, graduate students, and academics interested in subjects including Philosophy, Critical Race Theory, Sociology of Race, History of Biology and Anthropology, and Rhetoric of Science.

This volume reprints a dozen of the author’s papers, most with substantial postscripts, and adds one new one. The bulk of the material is on topics in philosophy of language, but there are also two papers on philosophy of mathematics written after the appearance of the author’s collected papers on that subject, and one on epistemology. As to the substance of Field’s contributions, limitations of space preclude doing much more below than indicating the range of issues addressed, and the general (...) orientation taken towards them. As to the style of his writing, it well exhibits the first of the two virtues, clarity and conciseness, that one looks for in philosophical prose. (shrink)

The source, status, and significance of the derivation of the necessity of identity at the beginning of Kripke’s lecture “Identity and Necessity” is discussed from a logical, philosophical, and historical point of view.

The complexity of the set of truths of arithmetic is determined for various theories of truth deriving from Kripke and from Gupta and Herzberger.

Mathematics tells us there exist infinitely many prime numbers. Nominalist philosophy, introduced by Goodman and Quine, tells us there exist no numbers at all, and so no prime numbers. Nominalists are aware that the assertion of the existence of prime numbers is warranted by the standards of mathematical science; they simply reject scientific standards of warrant.

In 1956 Jacques Lacan proposed as interpretation of Edgar Allan Poe's "Purloined Letter" that at once challenged literary theorists and revealed a radically new conception of psychoanalysis. Lacan's far-reaching claims about language and truth provoked a vigorous critique by Jacques Derrida, whose essay in turn has spawned further responses from Barbara Johnson, Jane Gallop, Irene Harvey, Norman Holland, and others. The Purloined Poe brings Poe's story together with these readings to provide, in the words of the editors, "a structured exercuse (...) in the elaboration of textual interpretation. The Purloined Poe reprints the full text of Poe's story, followed by Lacan's "Seminar on 'The Purloined Letter,'" along with extensive commentary by the editors. Marie Bonaparte's and Shoshana Felman's discussions of traditional and contemporary approaches to "psychoanalysing" texts precede Alan Bass's new translation of Derrida's "Purveyor of Truth." The subsequent essays join the Lacan-Derrida debate and offer alternative readings by literary theorists, philosophers, psychologists, and psychoanalysts. The Purloined Poe convenes much of the most important current scholarship on "The Purloined Letter" and presents a rich sampling of poststructuralist discourse. (shrink)

The form of nominalism known as 'mathematical fictionalism' is examined and found wanting, mainly on grounds that go back to an early antinominalist work of Rudolf Carnap that has unfortunately not been paid sufficient attention by more recent writers.

It is correctly asserted that the intensity of the current debate over the use of animals in biomedical research is unprecedented. The extent of expressed animosity and distrust has stunned many researchers. In response, researchers have tended to take a strategic defensive posture, which involves the assertion of several abstract positions that serve to obstruct resolution of the debate. Those abstractions include the notions that the animal protection movement is trivial and purely anti-intellectual in scope, that all science is good (...) (and some especially so), and the belief that an ethical consensus can never really be reached between the parties. (shrink)

A new axiomatization of set theory, to be called Bernays-Boolos set theory, is introduced. Its background logic is the plural logic of Boolos, and its only positive set-theoretic existence axiom is a reflection principle of Bernays. It is a very simple system of axioms sufficient to obtain the usual axioms of ZFC, plus some large cardinals, and to reduce every question of plural logic to a question of set theory.

There has been growing concern about whether individuals who satisfy neurological criteria for death or who become non-heart-beating organ donors are really dead. This concern has focused on the issue of the potential for recovery that these individuals may still have and whether their conditions are irreversible. In this article I examine the concepts of potentiality and irreversibility that have been invoked in the discussions of the definition of death and non-heart-beating organ donation. I initially focus on the recent challenge (...) by D. Alan Shewmon to accepting any neurological criterion of death. I argue that Shewmon relies on a problematic and unrealistic concept of potentiality, and that a better, more realistic concept of potentiality is consistent with accepting a neurological criterion for death. I then turn to an analysis of how the concept of irreversibility has been used in discussion of non-heart-beating organ donation. Similarly, I argue that some participants in this discussion have invoked a problematic and unrealistic concept of irreversibility. I then propose an alternative, more realistic account of irreversibility that explains how "irreversibility" should be understood in the definition and criteria of death. (shrink)

What role do moment‐to‐moment comprehension processes play in visual attentional selection in picture stories? The current work uniquely tested the role of bridging inference generation processes on eye movements while participants viewed picture stories. Specific components of the Scene Perception and Event Comprehension Theory (SPECT) were tested. Bridging inference generation was induced by manipulating the presence of highly inferable actions embedded in picture stories. When inferable actions are missing, participants have increased viewing times for the immediately following critical image (Magliano, (...) Larson, Higgs, & Loschky, ). This study used eye‐tracking to test competing hypotheses about the increased viewing time: (a) Computational Load: inference generation processes increase overall computational load, producing longer fixation durations; (b) Visual Search: inference generation processes guide eye‐movements to pick up inference‐relevant information, producing more fixations. Participants had similar fixation durations, but they made more fixations while generating inferences, with that process starting from the fifth fixation. A follow‐up hypothesis predicted that when generating inferences, participants fixate scene regions important for generating the inference. A separate group of participants rated the inferential‐relevance of regions in the critical images, and results showed that these inferentially relevant regions predicted differences in other viewers’ eye movements. Thus, viewers’ event models in working memory affect visual attentional selection while viewing visual narratives. (shrink)

This paper challenges the recommendation of 1981 President's Commission for the Study of Ethical Problems in Medicine and Biomedical and Behavioral Research that all jurisdictions in the United States should adopt the Uniform Determination of Death Act, which endorses a whole-brain, rather than a higher-brain, definition of death. I argue that the Commission was wrong to reject the "personhood argument" for the higher-brain definition on the grounds that there is no consensus among philosophers or the general population as to what (...) constitutes "personhood". I claim that philosophers agree that some potential for cognitive function is necessary for personhood and that, when this is absent in cases of anencephaly and persistent vegetative state (PVS), the individual should be considered dead. I further argue that the lack of consensus among the general population is due in large measure to misunderstandings about the medical reality of PVS and beliefs influenced by feelings for a specific individual in PVS. I also examine and reject two tutiorist arguments which have been used to support the Commission's position: that the higher-brain definition would threaten the severely senile and severely retarded, and that there are not currently adequate medical techniques for determining when all higher-brain activities have ceased.

Crowdfunding platforms have revolutionized entrepreneurial finance, with 200 billion dollars expected to be dispersed annually to entrepreneurs and small business owners by 2020.

We use a social responsibility lens to examine whether crowdfunders on a lending-based prosocial platform lend their money based on altruistic or strategic motives. Our results indicate that the dynamics of (...) prosocial lending-based crowdfunding are somewhat consistent with traditional forms of financing. Specifically, despite a prosocial setting in nature, crowdfunders tend to act strategically, positively responding to signals of quality and low risk. Notably, we also find that projects that are high on both financial and social appeal receive the highest average amount of funding. Furthermore, language on the lender’s profile indicating ability to pay is positively related to both funding success and funding amount. Our study contributes to filling the gap in the business ethics literature about the dynamics of lending-based prosocial crowdfunding, and the strategic and altruistic ethical motives that drive lenders in such endeavors.
