Responsible Research and Innovation provides a framework for judging the ethical qualities of innovation processes, however guidance for researchers on how to implement such practices is limited. Exploring RRI in the context of nanotechnology, this paper examines how the dispersed and interdisciplinary nature of the nanotechnology field somewhat hampers the abilities of individual researchers to control the innovation process. The ad-hoc nature of the field of nanotechnology, with its fluid boundaries and elusive membership, has thus far failed to establish a (...) strong collective agent, such as a professional organization, through which researchers could collectively steer technological development in light of social and environmental needs. In this case, individual researchers cannot innovate responsibly purely by themselves, but there is also no structural framework to ensure that responsible development of nanotechnologies takes place. We argue that, in such a case, individual researchers have a duty to collectivize. In short, researchers in situations where it is challenging for individual agents to achieve the goals of RRI are compelled to develop organizations to facilitate RRI. In this paper we establish and discuss the criteria under which individual researchers have this duty to collectivize. (shrink)

This paper explores the implications of conceptual entropy in interdisciplinary collaboration, examining perspectives from philosophy and contemporary social science. Conceptual entropy, the degree of disorder in a conceptual system, is analyzed from the viewpoints of those advocating for reducing ambiguity to achieve scientific precision, as well as those advocating for embracing ambiguity to reflect real-world complexity. We aim to demonstrate the need for conceptual clarity and thereby criticize deliberate conceptual vagueness. Semantic vagueness may arise due to fuzzy ontological mechanisms guarding (...) the relevant object domain. However, vagueness may also result from the unwarranted use of metaphors. We address the risk of precision loss in interdisciplinary teams by proposing a framework for studying conceptual entropy. On this basis, we argue that ‘conceptual entropy’ is useful for reflecting on how unclear, messy, and ambivalent concepts and conceptual systems may lead to an accelerating state of semantic disorder and vagueness.

The theme of the third annual Spring workshop of the HUPO-PSI was proteomics and beyond and its underlying goal was to reach beyond the boundaries of the proteomics community to interact with groups working on the similar issues of developing interchange standards and minimal reporting requirements. Significant developments in many of the HUPO-PSI XML interchange formats, minimal reporting requirements and accompanying controlled vocabularies were reported, with many of these now feeding into the broader efforts of the Functional Genomics Experiment data (...) model and Functional Genomics Ontology ontologies.

Techniques from artificial intelligence (AI) can be used in forensic evidence evaluation and are currently applied in biometric fields. However, it is generally not possible to fully understand how and why these algorithms reach their conclusions. Whether and how we should include such ‘black box’ algorithms in this crucial part of the criminal law system is an open question that has not only scientific but also ethical, legal, and philosophical angles. Ideally, the question should be debated by people with diverse (...) backgrounds. Here, we present a view on the question from the philosophy of science angle: computational reliabilism (CR). CR posits that we are justified in believing the output of an AI system, if we have grounds for believing its reliability. Under CR, these grounds are classified into ‘reliability indicators’ of three types: technical, scientific, and societal. This framework enables debates on the suitability of AI methods for forensic evidence evaluation that take a wider view than explainability and validation. We argue that we are justified in believing the AI’s output for forensic comparison of voices and forensic comparison of faces. Technical indicators include the validation of the AI algorithm in itself, validation of its application in the forensic setting, and case-based validation. Scientific indicators include the simple notion that we know faces and voices contain identifying information along with operationalizing well-established metrics and forensic practices. Societal indicators are the emerging scientific consensus on the use of these methods, as well as their application and interpretation by well-educated and certified practitioners. We expect expert witnesses to rely more on technical indicators to be justified in believing AIsystems, and triers-of-fact to rely more on societal indicators to believe the expert witness supported by the AIsystem.

Hamburg: Felix Meiner Verlag, 1998, 2000, 2004.The new critical Jacobi Werke Ausgabe (JWA), accompanied by four volumes of the still incomplete Briefwechsel (in progress at Frommann-Holzboog Publishers since 1981), is a masterpiece of research on Jacobi, early German Idealism and early Romanticism. Now [End Page 491] available are Volumes I, II and III. Volume I (1998) carries the title Schriften zum Spinozastreit and contains Jacobi's Spinozabriefe in the three editions of 1785, 1789, and 1819, Wider Mendelssohns Beschuldigungen of 1786, and the Vorbericht (Preface) of the third edition of the Spinozabriefe of 1819. The running text of all writings contains all editions, variant readings clearly identifiable with page references in the margins, subscripted to identify the various editions. This method enables the identification of various disputes which Jacobi provoked and in which his writings played a role. The Anhang, appendix, to all texts contains a) a list of abbreviations, and b) the editorial principles used and also a description of the circumstances leading to the writing of the texts. But the bulk of the Anhang of each volume is c) the "Kommentar," the commentary. It provides the key to the highly nuanced and, without guidance, the often cryptic allusions and references of Jacobi's texts. This commentary (separately bound in Volumes I and II) really brings Jacobi's work to life. The end of the Anhang contains d) a bibliography of all works mentioned not only by Jacobi himself but also emerging in the literary debate unlocked by the commentary, as well as e) an extensive index of names. Volume II (2004) is Schriften zur Transzendentalphilosophie, and contains David Hume of 1787, the Sendschreiben an Fichte, Ueberflüssiges Taschenbuch, both of 1799, and other essays such as Three Letters to Köppen of 1803. Volume III (2000) is Schriften zum Streit um die Göttlichen Dinge and contains mainly the famous essay Von den Göttlichen Dingen of 1811 plus three other writings. This book deals with the controversy between Schelling and Jacobi while both were at Munich. Other major works of Jacobi, such as the novel Allwill, are to follow in later volumes.This critical edition of Fr. H. Jacobi (1743–1819) definitively revises the standard interpretation of the man and his work. The standard interpretation (advocated by such figures as Fr. Schlegel, Moses Mendelssohn, and H. Heine) views his thought as promoting irrationalism, specifically a religious irrationalism of faith, taking form in "personalism." Heine spoke of Jacobi as a "whiney old biddy." Fr. Schlegel characterized Jacobi's salto mortale as the "leap into the arms of divine mercy," promoting an irrational "philosophical non-philosophy" (KFSA XVIII 13, Nr. 101). Schlegel criticized Jacobi at the very end of in his Woldemar Review of 1796 thus: "So (Jacobi's) Woldemar is really an invitation to meet God..., and (his) theological masterpiece ends, as do all moral excesses, with a salto mortale... into the abyss of divine mercy" (Früher Idealismus und Frühromantik PlS I.1, ed. W. Jaeschke [Hbg: Meiner, 1995], 270). Carl Philipp Moritz credited Jacobi with "fanaticism and superstition."In contrast, Jacobi himself was quite critical of this characterization of his thought, especially in the Sendschreiben of 1799, and earlier in his Briefe. Jacobi already in 1786 thought it was "outrageous" for Mendelssohn to suggest he surrenders a philosophy of reason in favor of the Christian faith, or worse. He addresses this problem, which is still today the dominant view of the "irrationality" of his "leap," with admirable clarity in his letter to Neeb of May 30, 1817: "I do not at all advocate a head-first...

Universalism vs. Communitarianism focuses on the question, raised by recent work in normative philosophy, of whether ethical norms are best derived and justified on the basis of universal or communitarian standards. It is unique in representing both Continental and American points of view and both the older and a younger generation of scholars. The essays introduce the key issues involved in universalism vs. communitarianism and take up ethics in historical perspective, practical reason and ethical responsibility, justification, application and history, and (...) communitarian alternatives. Based on a special issue of the Journal Philosophy and Social Criticism, the book includes two additional essays by Chantal Mouffe and by Hubert and Stuart Dreyfus.

The starting?point for this discussion is Rolf Gruner's ?On the Action of Social Groups? (Inquiry, Vol. 19 [1976]), in which it is argued that assemblies and institutions can be said to perform actions, while classes cannot. It is shown here that teams, which are groups distinct from both assemblies and institutions, can also be said to act. Some of the similarities and differences between teams and assemblies and institutions are noted; and, in particular, it is found that the relation between (...) the action of a team and the actions of its members differs from the corresponding relations in the cases of assemblies and institutions.

Traditional explanations of multistable visual phenomena (e.g. ambiguous figures, perceptual rivalry) suggest that the basis for spontaneous reversals in perception lies in antagonistic connectivity within the visual system. In this review, we suggest an alternative, albeit speculative, explanation for visual multistability – that spontaneous alternations reflect responses to active, programmed events initiated by brain areas that integrate sensory and non-sensory information to coordinate a diversity of behaviors. Much evidence suggests that perceptual reversals are themselves more closely related to the expression (...) of a behavior than to passive sensory responses: (1) they are initiated spontaneously, often voluntarily, and are influenced by subjective variables such as attention and mood; (2) the alternation process is greatly facilitated with practice and compromised by lesions in non-visual cortical areas; (3) the alternation process has temporal dynamics similar to those of spontaneously initiated behaviors; (4) functional imaging reveals that brain areas associated with a variety of cognitive behaviors are specifically activated when vision becomes unstable. In this scheme, reorganizations of activity throughout the visual cortex, concurrent with perceptual reversals, are initiated by higher, largely non-sensory brain centers. Such direct intervention in the processing of the sensory input by brain structures associated with planning and motor programming might serve an important role in perceptual organization, particularly in aspects related to selective attention.

We examined Confucian moral philosophy, primarily the Analects, to determine how Confucian ethics could help managers regulate their own behavior (self-regulation) to maintain an ethical standard of practice. We found that some Confucian virtues relevant to self-regulation are common to Western concepts of management ethics such as benevolence, righteousness, wisdom, and trustworthiness. Some are relatively unique, such as ritual propriety and filial piety. We identify seven Confucian principles and discuss how they apply to achieving ethical self-regulation in management. In addition, (...) we examined some of the unique Confucian practices to achieve self-regulation including ritual and music. We balanced the framework by exploring the potential problems in applying Confucian principles to develop ethical self-regulation including whistle blowing. Confucian moral philosophy offers an indigenous Chinese theoretical framework for developing ethical self-regulation in managers. This is relevant for managers and those who relate to managers in Confucian-oriented societies, such as China, Korea, Japan, and Singapore. We recommend further research to examine if the application of the Confucian practices outlined here actually work in regulating the ethical behavior of managers in modern organizations. (shrink)

I propose an analysis of the metaphysically important distinction between intrinsic and extrinsic properties, and, in the process, provide a neglected model for the analysis of recalcitrant distinctions generally. First, I recap some difficulties with Kim's well-known (1982) proposal and its recent descendants. Then I define two independence relations among properties and state a ‘quasi-logical’ analysis of the distinction in terms of them. Unusually, my proposal is holistic, but I argue that it is in a certain kind of equilibrium and (...) so probably pins down the target distinction uniquely. Finally, I suggest diagnoses of the previous failed attempts to analyse the distinction. (shrink)

I present, motivate, and defend a theory of properties. Its novel feature is that it takes entire determinables-together-with-their-determinates as its units of analysis. This, I argue, captures the relations of entailment and exclusion among properties, solves the problem of extensionality, and points the way towards an actualist analysis of modality.

Temporal binding refers to a phenomenon whereby the time interval between a cause and its effect is perceived as shorter than the same interval separating two unrelated events. We examined the developmental profile of this phenomenon by comparing the performance of groups of children (aged 6-7-, 7-8-, and 9-10- years) and adults on a novel interval estimation task. In Experiment 1, participants made judgments about the time interval between i) their button press and a rocket launch, and ii) a non-causal (...) predictive signal and rocket launch. In Experiment 2, an additional causal condition was included in which participants made judgments about the interval between an experimenter’s button press and the launch of a rocket. Temporal binding was demonstrated consistently and did not change in magnitude with age: estimates of delay were shorter in causal contexts for both adults and children. Additionally, the magnitude of the binding effect was greater when participants themselves were the cause of an outcome compared to when they were mere spectators. This suggests that although causality underlies the binding effect, intentional action may modulate its magnitude. Again, this was true of both adults and children. Taken together, these results are the first to suggest that the binding effect is present and developmentally constant from childhood into adulthood. (shrink)

There is a growing interest in assessing how cognitive processes fluidly adjust across trials within a task. Dynamic adjustments of control are typically measured using the congruency sequence effect (CSE), which refers to the reduction in interference following an incongruent trial, relative to a congruent trial. However, it is unclear if this effect stems from a general control mechanism or a distinct process tied to cross-trial reengagement of the task set. We examine the relationship of the CSE with another measure (...) of control referred to as the item-specific proportion congruency effect (ISPC), the finding that frequently occurring congruent items exhibit greater interference than items that are often incongruent. If the two effects reflect the same control mechanism, one should find interactive effects of CSE and ISPC. We report results from three experiments utilizing a vocal Stroop task that manipulated these two effects while controlling for variables that are often confounded in the literature. Across three experiments, we observed large CSE and ISPC effects. Importantly, these effects were robustly additive with one another (Bayes Factor for the null approaching 9). This finding indicates that the CSE and ISPC arise from independent mechanisms and suggests the CSE in Stroop may reflect a more general response adjustment process that is not directly tied to trial-by-trial changes in attentional control.

Language's intentional nature has been highlighted as a crucial feature distinguishing it from other communication systems. Specifically, language is often thought to depend on highly structured intentional action and mutual mindreading by a communicator and recipient. Whilst similar abilities in animals can shed light on the evolution of intentionality, they remain challenging to detect unambiguously. We revisit animal intentional communication and suggest that progress in identifying analogous capacities has been complicated by (i) the assumption that intentional (that is, voluntary) production (...) of communicative acts requires mental-state attribution, and (ii) variation in approaches investigating communication across sensory modalities. To move forward, we argue that a framework fusing research across modalities and species is required. We structure intentional communication into a series of requirements, each of which can be operationalised, investigated empirically, and must be met for purposive, intentionally communicative acts to be demonstrated. Our unified approach helps elucidate the distribution of animal intentional communication and subsequently serves to clarify what is meant by attributions of intentional communication in animals and humans.

This article makes the case that place-based and environmental education theory and practice must be responsive to, while attempting to transform, the institutional dynamics of schooling. In the present climate of education in the USA two dynamics of schooling deserve particular attention with respect to the possibilities for place-based and environmental education: the discourse of accountability and the discourse of collaboration. Drawing especially on Foucault's analyses of disciplinary power and governmentality, I show how practices associated with accountability and collaboration limit (...) or preclude the deepening and spreading of place-based and environmental education. However, I also argue that even given the serious limitations imposed by current trends of collaboration and accountability, these trends offer place-based and environmental educators powerful entry points through which to initiate change within the formal school setting. The conclusion of the paper outlines three models of collaboration for place-conscious education through which accountability is redefined in the interest of places. (shrink)

Professor Kenneth J. Arrow is one of the most distinguished economic theorists. He has played a major role in shaping the subject and is honoured by the publication of three volumes of essays on economic theory. Each volume deals with a different area of economic theory. The books include contributions by some of the best economic theorists from the United States, Japan, Israel and Europe.

In light of the foregoing, we conclude that hospital attorneys, risk managers, and other advocates despite the immense contribution which they may make to the process and deliberations of ethics committees—have a unique role in the bioethical decision-making process, but one that neither requires nor precludes membership on such committees. This is not to deny in any way appropriate access to committees or their deliberations by such advocates. Indeed, we would argue strongly that hospital attorneys and risk managers, where there (...) are reasons for including them in committee discussions, should be invited as consultants and participant-observers. Furthermore, we concur wit Gibson, who suggests that hospital attorneys have a teaching role which enhances the committee's understanding of relevant legal issues, cases, and decisions. this is especially true in individual case consultation. Ethics committees and institutional advocates both have important roles within health care institutions, but patients and hospitals are best served when these two agents collaborate without weakening or undermining their mutually distinct functions and priorities. This conclusion is based primarily on the widely acknowledged concern about conflict of interest as well as the more peripheral concern about loss of attorney/client privilege. However, we would argue that in all aspects of committee work, including self-education, policymaking and case review and consultation, these specialists in health law may often give expert advice and counsel to persons regarding a vast arrays of subjects. These include but are hardly limited to the following: Durable Power of Attorney for Health Care, Living Will Legislation, Malpractice Law, Orders Not to Resuscitate, Forgoing Life-Sustaining Treatment, Withholding Nutrition and Hydration, Treatment for Incompetent Patients, Proportionate vs. Disproportionate Treatment, and Suicide and the Law. HECs need to know how attorneys think and especially how hospital attorneys frame bioethical issues, just as they need to know how physicians and nurses think and respond. Even if hospital attorneys are not formally seated on HECs, they should participate in charting the currents in bioethics. Gibson feels that we need to re-examine the roles of the hospital attorney. Perhaps these advocates should be encouraged to wear more than just one “hat,” and for the rest of us to generalize about institutional advocates is both premature and prejudicial. When we stereotype attorneys with a generic label such as “institutional advocates,” we open ourselves to the dangers of an even narrower kind of “reflex advocacy” (11).To achieve open and honest dialogue, all voices and viewpoints must be heard. HECs that arbitrarily and totally exclude hospital attorneys from participation may exhibit the very close-mindedness they are seeking to eliminate. Yet this situation is at its core a paradoxical one: We cannot proscribe the advocate's role without constraining his or her effectiveness. Yet for the sake of their effectiveness we need to protect them from conflict-of-interest situations. Moreover, we also need to be certain that all points of view, including those that derive from the law, are given an adequate hearing by HECs. (shrink)

This paper consists in the Spanish translation of a manuscript by Franz Brentano, where he deals with “The Method of Study of Aristotle and, More Generally, the Method of Historical Research in Philosophical Field”. In these pages, Brentano challenges the Aristotelian studies of his time by criticizing the approach followed by E. Zeller and other scholars. Meanwhile, he suggests some hermeneutical rules in order to interpret Aristotle in the right way. The core of his proposal is the use of philosophical (...) hermeneutics, that is, the interpreter should philosophize following the Aristotelian arguments, like the Peripatetics used to do. In his introduction to the text by Brentano, the Spanish translator also recommends a new chronology for the manuscript, i.e. not much later than 1883.

Poverty, inequality, violence, environmental degradation, and tyranny continue to afflict the world. Ethics of Global Development offers a moral reflection on the ends and means of local, national, and global efforts to overcome these five scourges. After emphasizing the role of ethics in development studies, policy-making, and practice, David A. Crocker analyzes and evaluates Amartya Sen's philosophy of development in relation to alternative ethical outlooks. He argues that Sen's turn to robust ideals of human agency and democracy improves on (...) both Sen's earlier emphasis on 'capabilities and functionings' and Martha Nussbaum's version of the capability orientation. This agency-focused capability approach is then extended and strengthened by applying it to the challenges of consumerism and hunger, the development responsibilities of affluent individuals and nations, and the dilemmas of globalization. Throughout the book the author argues for the importance of more inclusive and deliberative democratic institutions. (shrink)

The editors of the invaluable "Philosophische Bibliothek" perceived the need of providing readers of German with translations of both the Prior and the Posterior Analytics, two volumes in their edition of the Organon that had been out of print for some time. Having lost hope—so they tell us in the Vorwort—of obtaining fresh versions of them in the near future, they decided to reprint the old Rolfes translation of the Posteriora which had appeared in the series for the first time (...) in 1922. In spite of Rolfes’s undeniable merits as a translator of Aristotle, the solution seems to be unsatisfactory. On the one hand, the quality of the Greek text and our understanding of Aristotelian idioms and terminology in this treatise have been improved considerably in the last fifty years. A landmark in this type of studies is doubtless the edition with an extensive and valuable commentary by Sir David Ross. On the other hand, contemporary developments in logic and philosophy of science have led to new and sometimes more accurate assessments of Aristotelian ideas on demonstrative science. There is in fact an excellent English translation with notes by Jonathan Barnes conceived along these lines. One token example of the disadvantages of a translation that cannot take into account scholarly work done after 1922 can be seen at 89b25-26 where Aristotle speaks about "putting into number" a certain type of question. Both Ross and Barnes warn us that the phrase is curious, that it is bizarre, and we may easily infer that not much weight should be put on it in interpreting the passage. Rolfes, on the contrary, has an uncritical attitude towards the expression. He translates it literally and then goes on to comment on it as if it were normal Aristotelian usage. Needless to say, this can easily mislead the unexperienced student of Aristotle to pursue a chain of false problems. But the tendency to translate as literally as possible has its advantages, and it is fair to say that Rolfes’s translation is sufficiently accurate to be of considerable help in many difficult passages.

This is a collection of essays on themes of legal philosophy which have all been generated or affected by Hart's work. The topics covered include legal theory, responsibility, and enforcement of morals, with contributions from Ronald Dworkin, Rolf Sartorius, Neil MacCormach, David Lyons, Kent Greenawalt, Michael Moore, Joseph Raz, and C.L. Ten, among others.

In this clear and reasoned discussion of self- knowledge and the self, the author asks whether it is really possible to know ourselves as we really are. He illuminates issues about the nature of self-identity which are of fundamental importance in moral psychology, epistemology and literary criticism. Jopling focuses on the accounts of Stuart Hampshire, Jean-Paul Sartre and Richard Rorty, and dialogical philosophical psychology and illustrates his argument with examples from literature, drama and psychology.

In "Does the Basic Color Terms discussion suffer from the Stimulus Error?" Rolf Kuehni describes a research stumbling block known as the "stimulus error," and hints at the difficulties it causes for mainstream color naming research. Among the issues intrinsic to Kuehni's "stimulus error" description is the important question of what can generally be inferred from color naming behaviors based on bounded samples of empirical stimuli. Here we examine some specifics of the color naming research issues that Kuehni raises. While (...) we share Kuehni's view regarding potential problems caused by the "stimulus error" and his concern regarding its prevalence, Kuehni's commentary seems primarily aimed at stimulating a general discussion of color naming research implications, because the articles he critiques do not actually commit the "stimulus error" in any serious sense. Based on Kuehni's comments, we further examine some of the relevant empirical and theoretical implications for cross-cultural color naming research. (shrink)

Philosophers and theologians from around the world and throughout history have grappled with such fundamental issues as the nature of the world and man's relation to it, as well as the optimal forms of human perception, language and behaviour. Yet it has always been difficult to compare the works of thinkers from different eras and cultures. In this work of systematic philosophy, David Dilworth places the major texts of ancient and modern, and Western and Oriental philosphy and religion into (...) one comparative framework. His study reveals affinities between thinkers who lived centuries and continents apart and produces numerous insights by bringing together the greatest philosophical texts into a single scheme.

Monogenesis of language is widely accepted, but the conventional argument seems to be mistaken; a simple probabilistic model shows that polygenesis is likely. Other prehistoric inventions are discussed, as are problems in tracing linguistic lineages. Language is a system of representations; within such a system, words can evoke complex and systematic responses. Along with its social functions, language is important to humans as a mental instrument. Indeed, the invention of language,that is the accumulation of symbols to represent emotions, objects, and (...) acts may be the most important event in human evolution, because so many developments follow from it. For example, Edward Sapir speculated that some embryonic form of language must have been available to early man to help him fashion tools from stone (Sapir,1921). Sophisticated biface stone tools date to early Homo erectus some 1.5 million years ago, suggesting a similar age for language. This paper considers whether the invention of language occurred at only one pre-historic site or at several sites. In other words, did language emerge by monogenesis or polygenesis? Early thinkers believed in monogenesis, against a background of divine creation. Perhaps the best known account is the biblical story of Adam giving names to plants and animals in the Garden of Eden. Similar legends are found among many peoples. Modern linguists too assume monogenesis, but on probabilistic grounds (see, for instance, Southworth and Daswani, 1974, p.314). The argument seems to be that the invention of language is an extremely unlikely event, because symbolization involves abstraction and requires synchronized insight by several individuals; therefore, the probability of occurrence at more than one site must be vanishingly small. We have found no explicit quantitative treatment of this question in the literature, but the underlying logic has to be the multiplication of probabilities. If p is small at one site,then p.p for two sites is smaller still, and so on. This reasoning is false, as we show here. The fallacy lies in the focus on two particular sites rather than consideration of all pairs of sites. (shrink)

Understanding how activity in the brain leads to a subjective percept is of great interest to philosophers and neuroscientists alike. In the last years, neurophysiological experiments have approached this problem directly by measuring neural signals in animals as they experience well-defined visual percepts. Stimuli in these studies are often inherently ambiguous, and thus rely upon the subjective report, generally from trained monkeys, to provide a measure of perception. By correlating activity levels in the brain to this report, one can speculate (...) on the role of individual neurons and groups of neurons in the formation and maintenance of a particular percept. However, in order to draw valid conclusions from such experiments, it is critical that the responses accurately and reliably reflect what is perceived. For this reason, a number of behavioural paradigms have been developed to control and evaluate the truthfulness of responses from behaving animals. Here we describe several approaches to optimizing the reliability of a monkey's perceptual report, and argue that their combination provides an invaluable approach in the study of subjective visual perception.
