This paper aims to develop the description of move systems in Systemic Functional Linguistics based on dynamism in knowledge exchanges, that is, the possible move options made available at different points in an exchange concerned with the negotiation of information. Using conversational interactions in Khorchin Mongolian as examples, the paper argues that at different points in a knowledge exchange, both the speaker and the addressee’s knowledge of the information are at stake. The speaker may be (...) positioned either as knowing or as not knowing the information; at the same time the addressee may be positioned either as knowing or as not knowing the information. It is also possible for the interlocutors not to be positioned either way. The move systems developed make it possible to discuss the options preselected and activated at different points in a knowledge exchange and the way interlocutors are dynamically positioned as an exchange unfolds.

An extensive body of literature in sociology and anthropology has shown that different societies have developed different structures for exchange of items such as goods, status and information. The purpose of this paper is to demonstrate how social exchange theory can help illuminate many of the underlying bases of different ethical perspectives in debates about social exchanges. Social exchange theory is applied to three common types of knowledge exchange – R&D joint ventures, commercial intellectual property (...) exchange and academic exchange. Two key factors that underlie different ethical perspectives are shown to be differences in structures for social exchange and differences in views of the alienability of knowledge from its originator.

Despite the intrinsic complexity of integrating individual, social and technologically supported intelligence, the paper proposes a relatively simple ‘connectionist’ framework for conceptualizing distributed cognitive systems. Shared information sources (documents) are represented as nodes connected by links of variable strength, which increases as the documents co-occur in the usage patterns. This learning procedure captures and exploits its users’ implicit knowledge to help them find relevant information, thus supporting an unconscious form of exchange. These principles are applied to a concrete (...) problem domain: architects sharing design knowledge through a database of associatively connected building projects. (shrink)

This paper explores how knowledge is exchanged between agricultural advisors and farmers in the context of sustainable farming practices in England. Specifically the paper examines the nature of the knowledge exchange at the encounters between one group of advisors, agronomists, and farmers. The promotion of best management practices, which are central to the implementation of sustainable agricultural policies in England, provide the empirical context for this study. The paper uses the notion of expert and facilitative approaches as (...) a conceptual framework for analyzing knowledge exchange encounters between agronomists and farmers. Data were derived from semi-structured interviews with 31 agronomists and 17 farmers, in the context of three initiatives promoting a range of best management practices including (a) targeted use of nitrogen (N), (b) use of nutrients within manure, and (c) management practices to improve soil structure. The interviews revealed that, although many agronomist–farmer knowledge exchange encounters are characterized by an imbalance of power, distrust, and the divergence of knowledge, other encounters provide a platform for the facilitation of farmer learning in their transition to more sustainable practices.

The publication presents research results on a multitude of knowledge exchange processes in post-enlightenment Europe. These focus on the question in how far deeply rooted processes of knowledge exchange by transnational intellectual discourses and international expert communities have contributed to a variety of networks of European intellectual identities and research practices. These practices again constitute a fertile framework for de-territorialised and de-nationalised exchange of knowledge that might contribute to contagious processes of emancipation, cooperation as (...) well as problem solving.

Knowledge is considered an essential resource and key to competitiveness. The behavior of sharing knowledge is an essential activity for the prosperity of the organization. For individuals, however, sharing knowledge can present a dilemma by giving up the exclusive right to certain knowledge that they own. This study identifies the psychological well-being as a leading factor in facilitating knowledge-sharing in dilemma situations. The author classified knowledge management behavior into sharing, hiding, and manipulating behavior, and (...) studied them as mediators linking psychological well-being and performance. And to check the influence of the quality of the exchange relationship, leader-member exchange was used as a moderator. For the empirical analysis, 333 members from 12 organizations were surveyed by using different sources and times. Hierarchical regression analysis and bootstrapping analysis were conducted for verification of hypothesis. Results demonstrated that the psychological well-being influence directly on knowledge-sharing, -hiding, and -manipulating behaviors and indirectly on performance. In the multi-mediation test, only knowledge-sharing behavior mediated the relationship between psychological well-being and performance. And the moderating effect of leader-member exchange was significant only in the relationship between psychological well-being and knowledge-sharing behavior. This study contributes to the performance, knowledge management and positive psychology research fields, and suggests practical implications. (shrink)

Professionals and researchers in the literature widely discuss the concept of knowledge sharing. This article aims to provide a theoretical framework for knowledge sharing from the perspective of selected factors such as altruism and social exchange theory (SET) and also discusses an epistemological approach to knowledge management and knowledge sharing. The main aim of this paper is to theoretically and empirically contribute to knowledge sharing in the University context. The paper also discusses the altruism (...) and knowledge sharing of students as individuals who may expect some recognition for sharing their tacit and explicit knowledge. Data confirm that there is often an altruistic approach among students. If they expect recognition, it is mainly on a group level. Groups of student respondents also gave a unique perspective on the influence of the COVID-19 Pandemic on the attitude toward sharing knowledge. (shrink)

A person’s financial well-being is the complete contentment gained from one’s present financial condition. This has a powerful impact on the entire achievement of an employee’s “well-being.” Researchers, financial analysts, financial planners, educationists, and economists have explored the “enablers” to improve employees’ living standards by investigating the possible “FWB” resources for decades. There is no literature available to show the connection between social capital theory, social exchange theory, social cognitive theory, financial literacy and FWB, and employees’ financial knowledge (...) sharing a moderator to expand the complete FWB.

The Exchange of Words is a philosophical exploration of human testimony, specifically as a form of intersubjective understanding in which speakers communicate by making themselves accountable for the truth of what they say. This account weaves together themes from philosophy of language, moral psychology, action theory, and epistemology, for a new approach to this basic human phenomenon.

Given that work teams have been widely used in a variety of organizations to complete critical tasks and that the use of social media in work teams has been growing, investigating whether and how team social media usage affects team creativity is imperative. However, little research has empirically explored how TSMU affects team creativity. This study divides TSMU into two categories, namely, work-related TSMU and relationship-related TSMU. Basing on communication visibility theory and social exchange theory, this study constructs a (...) moderating mediation model to understand how TSMU affects team creativity. In this model, team knowledge sharing is used as mediating role and team-member exchange is used as moderating role. Two-wave research data collected from 641 employees in 102 work teams in Chinese organizations are used for regression analysis. Results show that Work-related TSMU and relationship-related TSMU are positively affect team creativity. Team knowledge sharing plays a partly mediating effect on the relationship between work-related TSMU and team creativity and that between relationship-related TSMU and team creativity. TMX not only positively moderates the indirect effect of work-related TSMU and relationship-related TSMU on team creativity through team knowledge sharing. Theoretical and practical implications are also discussed. (shrink)

In her account of scientific objectivity, feminist philosopher of science Helen Longino shows how scientific objectivity is not so much of individual practice, but rather a social commitment practiced by a scientific community, provided by the necessary accommodations for critical discourse. However, is this conception of scientific objectivity truly capable of living up to the social realities of critical discourse and deliberation within a scientific community? Drawing from Dutilh Novaes’ social epistemological account of argumentation, this paper highlights the challenges Longino’s (...) scientific objectivity faces on a prescriptive and descriptive level, specifically in overcoming the various epistemic injustices Longino’s proposed structural accommodations for objectivity are still sensitive to. Dutilh Novaes’ social epistemological model of argumentation illustrates how the realities of critical debate too often don’t consist of true epistemic or knowledge exchange, even though such exchanges are essential to achieve Longino’s primary goal when redefining scientific objectivity: to wield out and address idiosyncratic background assumptions and individual bigotry that possibly influence a researcher’s scientific conduct.

Based on Kolchinsky and Wolpert’s work on the semantics of autonomous agents, I propose an application of Mathematical Logic and Probability to model cognitive processes. In this work, I will follow Bateson’s insights on the hierarchy of learning in complex organisms and formalize his idea of applying Russell’s Type Theory. Following Weaver’s three levels for the communication problem, I link the Kolchinsky–Wolpert model to Bateson’s insights, and I reach a semantic and conceptual hierarchy in living systems as an explicative model (...) of some adaptive constraints. Due to the generality of Kolchinsky and Wolpert’s hypotheses, I highlight some fundamental gaps between the results in current Artificial Intelligence and the semantic structures in human beings. In light of the consequences of my model, I conclude the paper by proposing a general definition of knowledge in probabilistic terms, overturning de Finetti’s Subjectivist Definition of Probability.

This paper explores the intricate relationship between the concept of “savage knowledge,” its significance during the ninteenth and twentieth centuries, and the emerging field of ethnoscience. It specifically focuses on the Amazon region as a pivotal area in the development of ethnoscience, examining the contributions of renowned naturalists Carl von Martius, Richard Spruce, and Richard Schultes, who each conducted scientific expeditions to the Amazon during this era. Their works are crucial in reevaluating the dynamic interplay between the Western perception (...) of the “savage,” the scientific principles that underpin it, and the geopolitics of knowledge exchange between countries in the global north and south. I argue that the contextual conditions which made possible the emergence of ethnoscience, including imperial assimilation, extraction, and coloniality, continue to exert influence on twentieth century political discourses concerning the integration of indigenous cultures into global politics. This influence is evident through the analysis of a UNESCO document in the second part of the paper. The study concludes that the incorporation of indigenous knowledge, systematised by ethnoscience, has often served as a pretext for controlling geographical areas historically regarded as “natural resources,” ultimately transforming them into reservoirs of indigenous epistemologies.

Standard philosophical explanations of the concept of knowledge invoke a personal goal of having true beliefs, and explain the other requirements for knowledge as indicating the best way to achieve that goal. In this highly original book, Steven L. Reynolds argues instead that the concept of knowledge functions to express a naturally developing kind of social control, a complex social norm, and that the main purpose of our practice of saying and thinking that people 'know' is to (...) improve our system for exchanging information, which is testimony. He makes illuminating comparisons of the knowledge norm of testimony with other complex social norms - such as those requiring proper clothing, respectful conversation, and the complementary virtues of tact and frankness - and shows how this account fits with our concept of knowledge as studied in recent analytic epistemology. His book will interest a range of readers in epistemology, psychology, and sociology. (shrink)

The paper provides a deeper insight into institutionally given opportunities for and limitations to reflexive, dialogue-centered, and risk-sensitive knowledge exchange between scientific experts and agro-political decision makers, especially under the conditions of a significant degree of complexity, far-reaching uncertainties and potential impacts. It focuses on the practical orientations, guiding expectations and selection criteria shaping expertise in processes of science policy consulting. In doing so, two perspectives will be discussed: first the orientation of the knowledge production process by (...) different concepts of ‘‘usable knowledge.’’ Second, the influence of specific constellations on different stages of the political process, which shape the institutional conditions for the transfer and the use of scientific knowledge within the policy consulting process. Both perspectives help to come to a closer understanding of the demanding and very heterogeneous process of science policy consulting, which - if successful - leads to the interactive production of a very special form of ‘‘orientational knowledge.’’.

In social systems or spaces, distance between the centre and the periphery breeds epistemic injustice. There are growing accounts of epistemic injustice in health-related fields, as in the article by Pratt and de Vries.1 The title of the article asks: ‘Where is knowledge from the global South?’ Like me, you may answer by saying: ‘Knowledge from the global South is in the global South’. That answer says a lot about how we right epistemic injustice done to actors in (...) the global South or the periphery, including in health ethics. Pratt and de Vries identified four sets of actors (individuals, institutions, journals and funders) responsible for righting epistemic injustice. For three of the four sets of actors, they recognised the need for—or the possibility of—symmetry between global North and global South. Except journals. They did not seriously consider that journals are either present in or could belong to the global South; to the periphery. Platforms for knowledge exchange, circulation, cultivation and curation—such as journals, conferences, publishers, blogs, archives, seminars, books and the media, social or traditional—are neither physically nor epistemically neutral. They are situated. The BBC cannot do for Nigeria or Australia what it does for Britain; neither can the BMJ. Many of us take our position at the centre or periphery as neutral, natural, necessary or permanent. But the African American writer Toni Morrison proved the opposite with her career: ‘I stood at the border, stood at the edge and claimed it as central. l claimed it as central, and let the rest of the world move over to where I was.’2 Although physically in the USA, Toni Morrison was writing ….

A satisfactory theory of linguistic communication must explain how it is that, through the interpersonal exchange of auditory, visual, and tactile stimuli, the communicative preconditions for the acquisition of testimonial knowledge regularly come to be satisfied. Without an account of knowledge-yielding communication this success condition for linguistic theorizing is left opaque, and we are left with an incomplete understanding of testimony, and communication more generally, as a source of knowledge. This paper argues that knowledge-yielding communication (...) should be modelled on knowledge itself. It is argued that knowledge-yielding communication occurs iff interlocutors coordinate on truth values in a non-lucky and non-deviant way. This account is able to do significant explanatory work: it sheds light on the nature of referential communication, and it allows us to capture, in an informative way, the sense in which interlocutors must entertain similar propositions in order to communicate successfully.

Assertions are the centre of gravity in social epistemology. They are the vehicles we use to exchange information within scientific groups and society as a whole. It is therefore essential to determine under which conditions we are permitted to make an assertion. In this paper we argue and provide empirical evidence for the view that the norm of assertion is justified belief: truth or even knowledge are not required. Our results challenge the knowledge account advocated by, e.g. (...) Williamson (1996), in general, and more specifically, put into question several studies conducted by Turri (2013, 2016) that support a knowledge norm of assertion. Instead, the justified belief account championed by, e.g. Douven (2006), seems to prevail. (shrink)

The paper discusses the publications of the Royal Swedish Academy of Sciences (RSAS) as part of a wider network of publication exchange, linking learned societies, libraries, and archives. The periodicals of the RSAS went through several reorganisations between 1813 and 1903, all to some extent related to their role in publication exchange. Although subject to many of the same deliberations of commercial value and institutional prestige as the expanding book trade, publication exchange offered a means of communication (...) for institutions with widely differing financial, linguistic and scientific status, and a forum for articulating a wide range of values significant in scientific publication. In the context of publication exchange, the roles of producers and consumers, and of publishers and repositories of scientific knowledge overlap, and librarians emerge alongside editors as central actors in scientific communication. Scientific editorship should be viewed not only as a means of disseminating scientific findings to wider audiences, but as designing a product that could be used to forge institutional connections, to acquire publications, and to build collections. The case of the RSAS periodicals highlights the importance of publication, not only for the distribution of scientific knowledge, but for its acquisition. (shrink)

In this paper we address the question of how it can be possible for a non-expert to acquire justified true belief from expert testimony. We discuss reductionism and epistemic trust as theoretical approaches to answer this question and present a novel solution that avoids major problems of both theoretical options: Performative Expert Testimony. PET draws on a functional account of expertise insofar as it takes the expert’s visibility as a good informant capable to satisfy informational needs as equally important as (...) her specific skills and knowledge. We explain how PET generates justification for testimonial belief, which is at once assessable for non-experts and maintains the division of epistemic labor between them and the experts. Thereafter we defend PET against two objections. First, we point out that the non-expert’s interest in acquiring widely assertable true beliefs and the expert’s interest in maintaining her status as a good informant counterbalances the relativist account of justification at work in PET. Second, we show that with regard to the interests at work in testimonial exchanges between experts and non-experts, PET yields a better explanation of knowledge-acquisition from expert testimony than externalist accounts of justification such as reliabilism. As our arguments ground in a conception of knowledge, which conceives of belief-justification as a declarative speech act, throughout the rearmost sections of this paper we also indicate to how such a conception is operationalized in PET.

This essay pushes the history of a scientific discipline, morphology, toward a broader philosophically informed and cross-disciplinarily engaged history of knowledge. It shows that by looking at how knowledge and practices circulated between scientific disciplines (such as biology) and technoscientific ones (like architecture and design) we can better understand how (morphological) knowledge was produced. By doing so, the analysis contributes to the study of the mechanisms of knowledge exchange between the organic and the technical worlds (...) and, more broadly, to the study of the dynamics of knowledge circulation. First, the essay analyzes the engineering studies of organic form conducted by the Austro-Hungarian botanist Raoul Heinrich Francé (1874–1943) and the Scottish polymath D’Arcy Wentworth Thompson (1860–1948). Subsequently, the essay moves to twenty-first-century morphogenesis. It examines the transfer of the notion of morphospace, a paleontological practice of data visualization, into biology-inspired architectural design. The conclusion deals with the broader features of knowledge transfer and circulation. Twentieth- and twenty-first-century morphologists successfully translate and transfer morphogenetic processes from nature into technical artifacts to achieve technical solutions to given problems. In the translation of organic morphogenesis into a technical process, evolution’s intrinsic historical contingency was deliberately left behind. (shrink)

Although both philosophers and scientists are interested in how to obtain reliable knowledge in the face of error, there is a gap between their perspectives that has been an obstacle to progress. By means of a series of exchanges between the editors and leaders from the philosophy of science, statistics and economics, this volume offers a cumulative introduction connecting problems of traditional philosophy of science to problems of inference in statistical and empirical modelling practice. Philosophers of science and scientific (...) practitioners are challenged to reevaluate the assumptions of their own theories - philosophical or methodological. Practitioners may better appreciate the foundational issues around which their questions revolve and thereby become better 'applied philosophers'. Conversely, new avenues emerge for finally solving recalcitrant philosophical problems of induction, explanation and theory testing. (shrink)

Originally published in 2004 in the Common Knowledge symposium “Talking Peace with Gods,” this article elaborates the nature and consequences of the perspectivist cosmologies of Amerindian societies. Contemporary Western cosmologies regard humans as ex-animals who became differentiated from other nonhuman species through the acquisition of advanced cognitive capacities. Amerindian cultures, by contrast, regard animals as ex-humans who became differentiated from both modern humans and other animal species via a series of physical adaptations. Underneath these physical differences, both humans and (...) nonhumans retain a shared human soul; what is more, each species perceives its own kind as human and all other kinds—including humans—as animals. Viveiros de Castro distinguishes this “perspectivism” from relativism: whereas Western relativism assumes multiple valid cultural models, Amerindian perspectivism holds that human and nonhuman species possess a common values system and cultural framework. While this commonality is ordinarily obscured by biologically grounded, perceptual differences, the gap in perspective may be bridged by shamans, whose gift of adopting nonhuman subjectivities enables them to see other species as they see themselves—namely, as humans partaking in human culture. Perspectivism influences both the practices that Amerindian peoples adopt toward nonhuman species and their attitudes toward other human groups, especially in the context of warfare. The Amerindian warrior’s capacity to overcome an enemy ultimately depends on a shaman-like entry into the subjectivity of another: rather than denying the personhood of his enemy, the Amerindian warrior must acknowledge the affinity between them.

Research using economic decision-making tasks has established that direct reciprocity plays a role in prosocial decision-making: people are more likely to help those who have helped them in the past. However, less is known about how considerations of mutual exchange influence decisions even when the other party’s actions are unknown and direct reciprocity is therefore not possible. Using a two-party economic task in which the other’s actions are unknown, study 1 shows that prosociality critically depends on the potential for (...) mutual exchange; when the other person has no opportunity to help the participant, prosocial behavior is drastically reduced. In study 2, we find that theories regarding the other person’s intentions influence the degree of prosociality that participants exhibit, even when no opportunity for direct reciprocity exists. Further, beliefs about the other’s intentions are closely related to one’s own motivations in the task. Together, the results support a model in which prosociality depends on both the social conditions for mutual exchange and a mental model of how others will behave within these conditions, which is closely related to knowledge of the self.

This paper gives a detailed analysis of four seed lists in the journals of John Locke. These lists provide a window into a fascinating open network of botanical exchange in the early 1680s which included two of the leading botanists of the day. Pierre Magnol of Montpellier and Jacob Bobart the Younger of Oxford. The provenance and significance of the lists are assessed in relation to the relevant extant herbaria and plant catalogues from the period. The lists and associated (...) correspondence provide the main evidence for Locke's own important, through modest contribution to early modern botany, a contribution which he would have regarded as a small part of the broader project of constructing a natural history of plants. They also provide a detailed case study of the sort of open and informal network of knowledge exchange in the early modern period that is widely recognised by historians of science, but all too rarely illustrated.

This chapter reviews a number of related problems in the epistemology of testimony, and suggests some dilemmas for any theory of knowledge that tries to solve them. Here a common theme emerges: It can seem that any theory must make testimonial knowledge either too hard or too easy, and that therefore no adequate account of testimonial knowledge is possible. The chapter then puts forward a proposal for making progress. Specifically, an important function of the concept of (...) class='Hi'>knowledge is to govern the acquisition and distribution of quality information within an epistemic community. Testimonial exchanges paradigmatically serve in the distribution role, but sometimes serve in the acquisition role. The resulting position, it is argued, explains why testimonial knowledge is sometimes easy to get, and sometimes much harder. (shrink)

In 1766 Jean-Jacques Rousseau, in exile from France and Switzerland, came to England, where he made the acquaintance of Margaret Cavendish Harley Bentinck, Duchess of Portland. The two began to botanise together and to exchange letters about botany. These letters contain salient statements about Rousseau's views on natural theology, gardens, botanical texts and exotic botany. This exchange entailed not only discussions about plant identifications and other botanical matters, but most important, reciprocal gifts of books and specimens in the (...) manner of gentlemanly scientific correspondence of the period. Rousseau volunteered his services as the Duchess's ‘herborist’ or plant collector, and collected specimens and seeds in her behalf; these were destined for her own extensive herbaria and other natural history collections. Rousseau, who elsewhere denied female talent for science, admired the Duchess's knowledge of natural history, acknowledging his own as inferior. Their correspondence ended when the Duchess sent him the Herbarium amboinense of Georg Rumpf (Rumphius), an important work of exotic botany. Rousseau considered exotic botany to be the antithesis of the domination-free nature from which he derived solace and inspiration. (shrink)

This article argues that the (epi)genetic, cultural, symbolic, and environmental transmission channels are insufficient to explain the structure of modern human societies. Economic exchange of knowledge embodied in goods and services constitutes an additional transmission channel that makes more efficient use of limited human cognitive capacity. Economic exchange results in a gradual shift in societies from task-based division of labor to cognitive specialization. This shifts scarce cognitive resources away from production and into learning. It accelerates learning and (...) reinforces the drive towards specialization. Cognitive specialization may constitute another “major transition” towards a higher level of aggregation in human societies, with properties that differ from symbolic transmission. Collective control of individual market-based exchange is ensured by means of economic institutions that put a constraint on individual behavior. (shrink)

One of the most influential thinkers of the 20th century, Sir Karl Popper here examines the problems connected with human freedom, creativity, rationality and the relationship between human beings and their actions. In this illuminating series of papers, Popper suggests a theory of mind-body interaction that relates to evolutionary emergence, human language and what he calls "the three worlds." Rene; Descartes first posited the existence of two worlds--the world of physical bodies and the world of mental states. Popper argues for (...) the existence of "world 3" which comprises the products of our human minds. He examines the interaction between mental states--hopes, needs, plans, ideologies or hypotheses--and the physical states of our brain. Popper forcefully argues against the materialism forwarded by many philosophers which denies the existence of mental states. Instead, he demonstrates that the problem of the interaction between mental and physical states remains unresolved. Knowledge and the Body-Mind Problem is based on Popper's never-before published lectures at Emory University in 1969. Popper has extensively revised the lectures but has retained their accessible format. He has also incorporated some of the discussions which followed the lectures, providing an engaging exchange between the philosopher and his audience. (shrink)

Ethnobiology has become increasingly concerned with applied and normative issues such as climate change adaptation, forest management, and sustainable agriculture. Applied ethnobiology emphasizes the practical importance of local and traditional knowledge in tackling these issues but thereby also raises complex theoretical questions about the integration of heterogeneous knowledge systems. The aim of this article is to develop a framework for addressing questions of integration through four core domains of philosophy - epistemology, ontology, value theory, and political theory. In (...) each of these dimensions, we argue for a model of “partial overlaps” that acknowledges both substantial similarities and differences between knowledge systems. While overlaps can ground successful collaboration, their partiality requires reflectivity about the limitations of collaboration and co-creation. By outlining such a general and programmatic framework, the article aims to contribute to developing “philosophy of ethnobiology” as a field of interdisciplinary exchange that provides new resources for addressing foundational issues in ethnobiology and also expands the agenda of philosophy of biology.

The Metaphysics of Knowledge presents the thesis that knowledge is an absolutely fundamental relation, with an indispensable role to play in metaphysics, philosophical logic, and philosophy of mind and language. Knowledge has been generally assumed to be a propositional attitude like belief. But Keith Hossack argues that knowledge is not a relation to a content; rather, it a relation to a fact. This point of view allows us to explain many of the concepts of philosophical logic (...) in terms of knowledge. Hossack provides a theory of facts as structured combinations of particulars and universals, and presents a theory of content as the property of a mental act that determines its value for getting knowledge. He also defends a theory of representation in which the conceptual structure of a content is taken to picture the fact it represents. This permits definitions to be given of reference, truth, and necessity in terms of knowledge. Turning to the metaphysics of mind and language, Hossack argues that a conscious state is one that is identical with knowledge of its own occurrence. This allows us to characterize subjectivity, and, by illuminating the "I"-concept, allows us to gain a better understanding of the concept of a person. Language is then explained in terms of knowledge, as a device used by a community of persons for exchanging knowledge by testimony. The Metaphysics of Knowledge concludes that knowledge is too fundamental to be constituted by something else, such as one's functional or physical state; other things may cause knowledge, but do not constitute it.

Drawing on Vilm Flusser's view of the relationship between humans and the computer (machines), I explore a new ontological framework for our beingin-the-world. I begin by raising critical questions regarding our endeavours and efforts to create endlessly expanding semiotic knowledge spaces based on technological innovation (e.g. Wikipedia or the Universal Electronic Library) in order to reflect on this development from a Flusserian perspective, i.e. as an anthropological challenge to designing interhuman relations. By searching for new ontological conditions for humans, (...) technology and knowledge, I want to probe into responses and new perspectives/models of knowledge sharing. How would we have to rethink the relation between semiotic telematic knowledge spaces and their structure/architecture, and the concrete given (our relationships, intersubjectivity, etc.)? What are the consequences of these findings for the macrosocial structures of encounter where knowledge exchange is a key element? Which are the epistemic models most suited to articulating a productive interdisciplinary knowledge exchange? My approach intends to weave knowledge and space, memory, technology and lived experience into an ontological fabric, and, in so doing, place humans and their communicative needs at the centre of my considerations.

Ras proteins function as critical relay switches that regulate diverse signaling pathways between cell surface receptors and the nucleus. Over the past 2‐3 years researchers have identified many components of these pathways that mediate Ras activation and effector function. Among these proteins are several guanine nucleotide exchange factors (GEFs), which are responsible for directly interacting with and activating Ras in response to extracellular stimuli. Analogous GEFs regulate Ras‐related proteins that serve other diverse cellular functions. In particular, a growing family (...) of proteins (Dbl homology proteins) has recently been identified, which may function as GEFs for the Rho family of Ras‐related proteins. This review summarizes our current knowledge of the structure, biochemistry and biology of Ras and Rho family GEFs. Additionally, we describe mechanisms of GEF activation of Ras in signal transduction and address the potential that deregulated GEFs might contribute to malignant transformation through chronic Ras protein activation.

This paper explores the meaning of interpretation in the works of Hans-Georg Gadamer and Glenn Gould, the Canadian pianist and intellectual. As a performing art, music illustrates the cognitive and practical dimensions of interpretation. While emphasizing the pre-interpreted character of musical reception and performance, both authors point to the fact that difference, alterity, and negativity lie at the heart of creative interpretation, cultivation and self-knowledge. The notion of ecstasy, understood as a type of self-forgetfulness that represents a radical form (...) of encounter with alterity, provides the basis for a conception of subjectivity as grounded on linguistic, historical and cultural conditions, albeit not reducible to them. I maintain that the notion of ecstatic subjects is a powerful alternative to both the self-centred notion of subjectivity and its anti-humanistic counterpart in accounting for human agency. (shrink)

Most work in the epistemology of testimony is built upon a simple model of communication according to which, when the speaker asserts that p, the hearer must recover this very content, p. In this paper, I argue that this ‘Content Preservation Model’ of communication cannot bear the weight placed on it by contemporary work on testimony. It is popularly thought that testimonial exchanges are often successful such that we gain a great deal of knowledge through testimony. In addition, the (...) testimonial knowledge so gained is thought to be informative: it closes off epistemic possibilities for the agent. However, in the literature on truth-conditional content, there is no theory of content that can underpin both of these commitments simultaneously if the Content Preservation Model is true. There is a minimal notion of content, which is commonly preserved in communication, but which is typically uninformative; there is a maximal notion of content, which is often informative, but which is not often preserved in communication; and, although there are moderate positions between these two extremes, these views cannot strike the right balance between informativeness and shareability. Thus, an epistemology of testimony that endorses the Content Preservation Model faces a dilemma: on the first horn, testimonial exchanges are rarely successful; on the second horn, testimonial content is rarely informative. I suggest that this dilemma motivates further exploration of alternative communicative foundations for the epistemology of testimony. (shrink)

The German–American physiologist Jacques Loeb (1859–1924) and the Polish embryologist Emil Godlewski, jr. (1875–1944) contributed many valuable works to the body of developmental biology. Jacques Loeb was world famous at the beginning of the twentieth century for his development and demonstration of artificial parthenogenesis in 1899 and his experiments on regeneration. He served as a role model for the younger Polish experimenter Emil Godlewski, who began his career as a researcher like Loeb at the Zoological Station in Naples. Following Godlewski’s (...) first visit to Naples in 1901 a close relationship between the two scientists developed. Until Loeb’s death in 1924 the two exchanged ideas via correspondence that was only interrupted during the First World War. The aim of the paper is to examine the transatlantic transfer of knowledge in the field of biological experimentation that was fostered by these two protagonists. Using a modification of Bruno Latour’s model of the ‘Circulatory System of Science’ as a heuristic tool, different mechanisms of scientific exchange are displayed. With the help of Loeb’s and Godlewski’s correspondence the role of scientific communities, methods, allies, the public and institutions in the process of knowledge transfer are analysed. Preconditions for success and failure in transferring science are examined. (shrink)

This essay looks at early‐modern Venice hydroculture as a case of episteme from below. The forms of water knowledge it developed were multilayered and collective in their essence and solidly rested on a social experiential basis that was rooted in labour (especially fishing) and practices (especially water surveying and engineering). In accordance with the city's republican esprit (and correspondent political values), its episteme emerged as the encounter and negotiation between various institutions and groups: the fishermen of San Niccolò in (...) Venice, the practitioners of the water magistrature and political authorities. This essay explores the institutional settings of this water culture, seen as an instance of bottom‐up epistemic construction. It especially addresses three historical instances: firstly, a seventeenth century program to map public waters in order to block their alienation for private fish farming; secondly, water officers’ interviews with fishermen aimed to assess the state of the lagoon hydromorphology and, thirdly, fishing regulations. Venice communitarian and circular forms of knowledge production are here contrasted to an opposite paradigm, which was embodied by the Galileian mathematician and Rome courtier, Benedetto Castelli. His interactions with the Republic of Venice on water management and his approach to hydraulic problems are revealing of an elitist and abstract understanding of scientific knowledge that guided political decisions from above without taking in any consideration the opinions of the ‘vulgar’. While his science was the expression of a top‐down political epistemology, Venetian water knowledge was more egalitarian. It left room for exchange, inclusiveness and bottom‐up codification; it valued the gathering of different experiences (including the fishermen's practical knowledge of their waters) and rested on a concrete and systemic (organicist) understanding of natural‐anthropic processes.
