ArgumentAn unusual compass, on which east and west are reversed, provides insight into the dynamics guiding our understanding of artifacts. By examining how such compasses were used in Tokugawa Japan (1600–1868), the benefits they brought, and how users knew how to read them, this article uncovers the cognitive factors that shape our interaction with technology. Building on the methodological approach of thedistributed cognitiontheory, the article claims that reverse compasses allowed the user to conserve cognitive effort, which was particularly advantageous to (...) Tokugawa-period mariners. Moreover, the article shows that even non-professional Tokugawa Japanese had a relatively easy time reading reverse compasses due to similarity between the compasses’ orientation and Tokugawa timekeeping practices. Building on the bodily and cognitive habits they had developed through the practices of keeping time, users could identify and interpret cultural cues embedded in the structure of reverse compasses.

According to manipulationist accounts of causal explanation, to explain an event is to show how it could be changed by intervening on its cause. The relevant change must be a ‘serious possibility’ claims Woodward 2003, distinct from mere logical or physical possibility—approximating something I call ‘scientific possibility’. This idea creates significant difficulties: background knowledge is necessary for judgments of possibility. Yet the primary vehicles of explanation in manipulationism are ‘invariant’ generalisations, and these are not well adapted to encoding such knowledge, (...) especially in the social sciences, as some of it is non-causal. Ceteris paribus (CP) laws or generalisations labour under no such difficulty. A survey of research methods such as case and comparative studies, randomised control trials, ethnography, and structural equation modeling, suggests that it would be more difficult and in some instances impossible to try to represent the output of each method in invariant generalisations; and that this is because in each method causal and non-causal background knowledge mesh in a way that cannot easily be accounted for in manipulationist terms. Ceteris paribus-generalisations being superior in this regard, a theory of explanation based on the latter is a better fit for social science. (shrink)

Richard Cytowic has done considerable service to the scientific study of synesthesia, conducting important research and publishing two recent books on the subject. The study of synesthesia raises interesting questions about scientific method, both because of the negative reception it received initially--often being viewed as tainted by a reliance upon introspective reports--and because of the connections Cytowic has found between synesthetic perception and the limbic system, thereby possibly undermining some of the claims to objectivity in perception and scientific method. I (...) dispute some of the more extreme methodological conclusions Cytowic draws from his work and reinforce others by reference to different arguments current within the philosophy of science.

The ArgumentThere can be no doubt about the moral and epistemological significance of what Shapin calls the “physical place” of the scientific laboratory. The physical place is defined by the locales, barriers, ports of entry, and lines of sight that bound the laboratory and separate it from other urban and architectural environments. Shapin's discussion of the emergence of the scientific laboratory in seventeenth-century England provides a convincing demonstration that credible knowledge is situated at an intersection between physical locales and social (...) distinctions. In this paper I take up Shapin's theme of the “siting of knowledge production,” but I give it a different treatment – one based on ethnomethodological studies of work. Without denying all that can be witnessed in the spectacle of the scientist at the bench and of the architectural habitat of the bench, I argue that the “place” of scientific work is defined by locally organizedtopical contextures. The paper describes two examples of such spatial orders – “opticism” and “digitality” – associated with distinct complexes of equipment and practice. These topical spaces might initially be viewed as “ideal” or “symbolic” spaces, but I argue that they are no less material than the “physical setting” of the laboratory; indeed, they are the physical setting.

The ArgumentContemporary natural sciences succeed remarkably well in ensuring a relatively continuous transmission of their cognitively relevant traditions and in creating a widely shared background consensus among their practitioners – hermeneutical ends seemingly achieved without hermeneutical awareness or explicitly acquired hermeneutical skills.It is a historically specific – emerging only in the nineteenth century – cultural organization of the Author-Text-Reader relation which endows them with such an ease of hermeneutical achievements: an institutionally fixed form of textual and intertextual practices, normatively posited (...) ways of adequate reception and criticism, etc. The same organization also explains a number of their often-discussed epistemic and cultural characteristics: their depersonalized objectivity, the social closure of their discourse and their reduced cultural significance, the shallow historical depth of their activated traditions, etc.The cognitive structure and the social function of contemporary natural sciences are intimately interwoven with a set of sui generis cultural relations that are partially fixed in the textual characteristics of their literary objectivations. A comparative hermeneutical analysis of natural sciences as a specifically constituted and institutionalized cultural genre or discourse-type brings into relief those contingent cultural conditions and relations to which some of their fundamental epistemological characteristics are bound, or at least with which they are historically closely associated.

Austrian economics starts out from the thesis that the objects of economic science differ from those of the natural sciences because of the centrality of the economic agent. This allows a certain a priori or essentialistic aspect to economic science of a sort which parallels the a priori dimension of psychology defended by Brentano and his student Edmund Husserl. We outline these parallels, and show how the theory of a priori dependence relations outlined in Husserl’s Logical Investigations can throw light (...) on the Austrian account of entrepreneurship.

Este artículo discute varios modos de entender la racionalidad de la ciencia como racionalidad práctica. En primer lugar, rechaza los modelos instrumentalistas de la racionalidad científica, porque no pueden mostrar la independencia y la bondad de fines definidos para la ciencia, en relación con los cuales se establece la fuerza normativa de las razones. La errónea identificación de fines y valores es lo que provoca numerosas confusiones en este terreno. Se critica, en segundo lugar, un modelo de racionalidad práctica basado (...) en el dominio de saberes tácitos y habilidades. Cualquiera de los modelos propuestos ha de acomodarse a tres restricciones sobre lo que puede ser una "buena razón" dentro de la ciencia y que conforman la identidad práctica y el rostro normativo de la ciencia: publicidad, fiabilidad y autoridad reflexiva. This paper discusses some ways of understanding scientific rationality as practical rationality. Firstly, instrumental models of the rationality of science are rejected. The instrumentalist can hardly establish the independence and goodness of certain ends. In the case of science, determinate ends with respect to which the normative force of our reasons is established do not seem to exist. A false identification of ends with values is what causes many of the confusions. Secondly, a model of practical rationality based in the mastery of tacit knowledge and skills is criticized. Any model of scientific rationality should take into account three constraints about what a "good reason" in scientific matters is, constraints that shape the practical identity and the normative face of science: the constraints of publicity, reliability and reflective authority.

A general definition of consciousness that accommodates most views (Vimal, 2010b) is: “ ‘consciousness is a mental aspect of a system or a process, which is a conscious experience, a conscious function, or both depending on the context and particular bias (e.g. metaphysical assumptions)’, where experiences can be conscious experiences and/or non-conscious experiences and functions can be conscious functions and/or non-conscious functions that include qualities of objects. These are a posteriori definitions because they are based on observations and the categorization.” (...) Non-conscious experiences are equivalent to relevant proto-experiences and nonconscious functions are equivalent to related proto-functions at various levels as these terms are precursors of respective conscious subjective experiences and conscious functions aspect of consciousness. The non-conscious experiences and non-conscious functions may be considered as a part of the definition of mind and/or awareness. (shrink)

How engineers know, and act on that knowledge, has a profound impact on society. Consequently, the analysis of engineering knowledge is one of the central challenges for the philosophy of engineering. In this article, we present a thematic multidisciplinary conceptual survey of engineering epistemology and identify key areas of research that are still to be comprehensively investigated. Themes are organized based on a survey of engineering epistemology including research from history, sociology, philosophy, design theory, and engineering itself. Five major interrelated (...) themes are identified: the relationship between scientific and engineering knowledge, engineering knowledge as a distinct field of study, the social epistemology of engineering, the relationship between engineering knowledge and its products, and the cognitive aspects of engineering knowledge. We discuss areas of potential future research that are underdeveloped or “undone.”. (shrink)

Suppose you are on a commercial airplane that is flying at 35,000 feet. Next to you sits a man who appears to be sleeping. In fact, this man has been drugged and put upon the plane without his knowledge or consent. He has never flown on a plane before and, indeed, has no idea what an airplane is. Suddenly the man awakes and looks around him. Terrified by the alien environment in which he finds himself, he searches for a door (...) or window from which to make an escape. As luck would have it, he is seated right next to a window exit and he begins to pull the handle that will open the window. You are aware that opening the window exit at this altitude will cause the cabin to quickly depressurize and that this man, you, and probably several other passengers will be sucked out the window to your deaths. You desperately want to stop him from opening the window. Now assume that for some reason it is impossible to prevent him physically from performing the deadly act. Your only option is to rationally persuade him to leave the window exit alone. You cry out to him and, with both hands on the handles, he turns to face you and waits to hear what you have to say. What sort of argument would you make? (shrink)

The aim of this paper is to show that science, understood as pure research, ought not to be affected by non-epistemic values and thus to defend the traditional ideal of value-free science. First, we will trace the distinction between science and technology, arguing that science should be identified with pure research and that any non-epistemic concern should be di­rected toward technology and technological research. Second, we will examine different kinds of values and the roles they can play in scientific research (...) to argue that science understood as pure research is mostly and in any case ought to be value-free. Third, we will consider and dismiss some widespread arguments that aim to defend, especially at a normative level, the inevitable value-ladenness of science. Finally, we will briefly return to the connections among science, technology, and values. (shrink)

The ArugmentThis essay answers a single question: what was Robert Hooke, the Royal Society's curator of experiments, doing in his well-known 1665 work,Micrographia?Hooke was articulating a “universal cure of the mind” capable of bringing about a “reformation in Philosophy,” a change in philosophy's interpretive practices and organization. The work explicated the interpretive and political foundations for a community of optical instrument users coextensive with the struggling Royal Society. Standard observational practices would overcome the problem of using nonstandard instruments, while inherent (...) inrepresentation– the interpretive practice championed in the text – were important theological and political meanings. Hooke's kind of experimental philosophy undermined the claims made by “atheists” and “enthusiasts” – the enemies of the restored church and state – while also producing useful knowledge. Equally important, Hooke modeled the community described inMicrographiaupon the classicalres publica, but his community made important concessions to Restoration political realities, especially the growing role of commercial or transactional relationships.

ABSTRACT The need to cooperate in countless ways in a democracy raises the fundamental question posed by the prisoner's dilemma: How can self‐interested individuals cooperate? Tocqueville recognized this problem and anticipated the most convincing solution to date: Robert Frank's conception of emotions as “commitment devices.” Tocqueville's analysis of the miscalculations of modern “individualism,” which lead people first into isolation and then into servitude, mirrors the failure of conscious rationality in the prisoner's dilemma. Conversely, Tocqueville emphasizes emotional “habits of the heart” (...) as the key to resisting the blandishments of individualism. (shrink)

In this talk, I want to present a conception that I have been working on for a number of years (Zwick, 1983, 1995) about the use of systems ideas. I start from the negative and proceed to the positive. The negative assertion is that systems ideas by themselves , unsupplemented by more specific and concrete knowledge (e.g., from the various disciplines), are insufficient for practical application, either for obtaining knowledge about the world or for solving problems. The reason for this (...) is the inherent abstractness of these ideas. The positive assertion is that this metaphysics can be a rich source of insights needed to improve the human condition and a component of a new scientific world view. (shrink)

La obra es un estudio de una de las nociones fundamentales en la filosofía de Gadamer, el concepto de aplicación. Se intenta dar cuenta de la manera en que dicho concepto viene a solucionar, o tal vez sería mejor decir, a disolver, en la reflexión del siglo XX, el problema que enfrentaban las ciencias históricas en el siglo XIX para convertirse en conocimiento objetivo. Dicho problema consistía en dos importantes dificultades vinculadas entre sí: la imposibilidad de disponer de un objeto (...) independiente, el pasado “tal cual ocurrió” para confrontar la adecuación de las visiones del mismo constituidas desde el presente, por un lado, y la imposibilidad de erradicar la perspectiva del presente (intereses, ideologías, etc.)en los relatos históricos. Para abordar este problema, Gadamer acomete nada menos que una revisión de las categorías fundamentales en las cuales se inserta esta dificultad, esto es, las nociones de conocimiento, realidad y verdad modeladas, a través de Kant, de acuerdo a la perspectiva de la moderna ciencia de la naturaleza. Un paso fundamental será entonces examinar el problema del valor cognitivo del arte, esto es, elucidar las nociones de realidad y experiencia a partir de la experiencia artística, para extender luego estas conclusiones a la historia y el lenguaje. En el marco de esta revisión se perfila el concepto de aplicación, el cual destaca que nuestra condición de agentes históricos, insertos en una tradición y en una comunidad lingüística, no es un obstáculo, sino justamente la condición que hace posible que podamos comprender lo diferente a lo propio, ya sea en la forma de la alteridad histórica, lingüística o meramente personal. La tesis de la obra que presentamos es que la estructura de la aplicación, con la consecuente historicidad que acarrea, se presenta de manera semejante tanto en las macro-estructuras de la comprensión (comprensión de textos, de la tradición, del arte) como en las estructuras de un nivel inferior o más básico, como la realización de juicios y la comprensión de conceptos, punto que se elabora, en esta obra, a través de una comparación con las ideas del segundo Wittgenstein.

Excerpts from Chapters 1 and 3 of New Maps for Old: Explorations in Science and Religion (Gerhart and Russell 2001) explore the ramifications of metaphoric process for changes in thinking, especially those changes that lead to a new understanding of our world. Examples are provided from science, from religion, and from science and religion together. In excerpts from Chapter 8, a double analogy—theology is to science as science is to mathematics—is proposed for better understanding the contemporary relationship between science and (...) religion. A conservation of epistemological sufficiency is disclosed as one moves from mathematics to empirical science to theology—a move from one discipline to another that involves a sacrifice of one aspect of thought to gain another.

Aristotle's claim that natural slaves do not possess autonomous rationality (Pol. 1.5, 1254b20-23) cannot plausibly be interpreted in an unrestricted sense, since this would conflict with what Aristotle knew about non-Greek societies. Aristotle's argument requires only a lack of autonomous practical rationality. An impairment of the capacity for integrated practical deliberation, resulting from an environmentally induced excess or deficiency in thumos (Pol. 7.7, 1327b18-31), would be sufficient to make natural slaves incapable of eudaimonia without being obtrusively implausible relative to what (...) Aristotle is likely to have believed about non-Greeks. Since Aristotle seems to have believed that the existence of people who can be enslaved without injustice is a hypothetical necessity, if those capable oí eudaimonia are to achieve it, the existence of natural slaves has implications for our understanding of Aristotle's natural teleology.

The paper shows epistemological, methodological and ontological peculiarities of chemistry taken as a classificatory science of materials using experimental methods. Without succumbing to standard interpretations of physical science, chemical methods of experimental investigation, classification, reference, theorizing, prediction and production of new entities are developed one by one as first steps towards a philosophy of chemistry. Chemistry challenges traditional concepts of empirical object, empirical predicate, reference frame and theory, but also the distinction commonly drawn between natural science and technology. Due to (...) its many peculiarities, I propose to treat chemistry philosophically as a special type of science, apart from other sciences. (shrink)

If education is to make a difference it is widely acknowledged that we must aim to educate for understanding, but this means being clear about what we mean by understanding. This paper argues for a concept of personal understanding, recognising both the commonality and individuality of each pupil's understandings, and the relationship between understanding and interpretation, analysis and synopsis, and the quest for meaning. In supporting this view, the paper advocates an emergentist notion of person‐hood, and considers the neurophysiological reasons (...) for asserting the individuality of human minds, brains, and the creation of personal meanings. The notion of personal meanings would, however, seem to run counter to the post‐modern denial of the autonomous self, and the tradition in philosophy, most recently stemming from Wittgenstein, that insists that meanings and understandings are essentially social, and not personal—a view also advocated by John White in regard to education. In contrast, this paper argues that meanings and understandings are both social and personal. Once we reinstate the notion of personal minds and personal understandings, alongside the social, we may see more clearly what it means to educate for understanding, and why this might begin to make a difference.

Imre Lakatos gained fame in the English-speaking world as a follower and critic of philosopher of science Karl Popper. However, Lakatos’ background involved other philosophical and scientific sources from his native Hungary. Lakatos surreptitiously used Hegelian Marxism in his works on philosophy of science and mathematics, disguising it with the rhetoric of the Popper school. He also less surreptitiously incorporated, particularly in his treatment of mathematics, work of the strong tradition of heuristics in twentieth century Hungary. Both his Marxism and (...) his emphasis on heuristics contained a view of science and mathematics that contrasted with the mainstream of Anglo-American philosophy of science. Both involved a dynamic view of science, whether historical or psychological, and an emphasis on practice as opposed to static, formal representations of scientific theories. (shrink)

Despite the exceptional growth of interest in the Capability Approach in specific fields of application, the approach has yet to clarify certain basic concepts, such as freedom, functioning, and, in particular, its key concept of capability. Taking two basic tenets of CA as my starting point, I would first of all like to contribute to the clarification of these central concepts. It thereby becomes apparent that “capability” is, on the one hand, an essentially hybrid concept with both an internal and (...) external aspect. On the other hand, it addresses the freedom of choice between various lifestyles as a second-order competency. Against this background, this paper offers a suggestion to correct the terminology used by Martha C. Nussbaum in her concept of capability, and subsequently it will outline a basic model of the transformation of resources into forms of being and activities with reference to Ingrid Robeyns. In conclusion I will couple this rather static perspective with two critical points: First of all, a more dynamic view reveals hitherto barely considered aspects of freedom in everyday human lives. Secondly, the idea of capabilities opposes the attempt at a separation of capabilities from functions in order to avoid paternalism, as suggested by Nussbaum. (shrink)

In this discussion, we consider the unity of knowledge, and deliberate a contrary perspective from current knowledge transfer practitioners, in a business context. We consider why, if knowledge is key for business success and competitive advantage, the transfer of knowledge remains for the most part a problematic event. Further, ifthe creation of knowledge before transfer is recognised within literature as a significant factor in determining a starting point for analogous scrutiny, then why is this focal point difficult to establish and (...) measure.

This discussion surrounds the dialectical methodology, underpinning the unity of knowledge, and discusses a differing perspective to knowledge and knowledge value from knowledge transfer practitioners, in a business context. It asks why, if knowledge is vital for business success and competitive advantage, the transfer of knowledge is rarely a simple unproblematic event (Argote et al. 2000). Further, that the creation of knowledge before transfer is recognised within literature as a significant factor in determining a starting point for analogous scrutiny. Under (...) a premise of doxastic attitude, this discussion looks to synthesise from current literature and research the epistemic principal of ‘knowledge’, which underpins understanding congruent knowledge transfer theories and perspectives principals.

To allow a pragmatic approach to understanding value of knowledge as a ‘thing’ to be transferred, the axiological foundationalism significance of the human perception of knowledge continues to be a significant contributing factor. Similarly the construct of our knowledge is parallel to doxastic attitudes and perspectives. Thus, through reconciliation of foundational and doxastic positions, one can view knowledge and knowledge value as a singular construct. This can be characterised through a multitude definition but not as a singular epistemic principal. This (...) interpretation of current and historical literature offers an outline and assessment of current and historical knowledge philosophy, theory and positioning, but at the same time, tries to place it within the realms of a business context.

Learning about ‘nature’ has particular significance for education because the idea of nature is an important source of inspiring meaning‐rich experience and creation. In order to have meaningful experiences in learning and living, this paper argues for a personal subject‐related lifeworld approach to the learning of ‘nature’. Many authors claim that the lifeworld‐led learning approach helps to enrich educational experience. However, there can be various interpretations of the lifeworld approach, as the concept of lifeworld is diversely understood. This paper proposes (...) a personal, subject‐related lifeworld approach from a Husserlian‐Merleau‐Pontian perspective. I suggest that it holds great potential for improving our current curriculum which suffers from meaning‐impoverishment. This paper comprises the following parts: the elucidation of the lifeworld approach to learning, a demonstration of the flaws of current curricula by discussing and analysing the Taiwanese curriculum guidelines, and an exposition of the contribution of the Husserlian‐Merleau‐Pontian lifeworld approach towards improving our current curriculum.

A more reflexive account of phronesis, it is suggested, needs to clarify the potentiality of phronesis for co‐ordination as it promotes patterns of unity in difference and difference in unity.

In this article, I discuss the contribution of theoretical resources to the transformation in my thinking about professional development and accountability, within an action research self-study of practice as a civil servant, in the context of participation on the Doctor in Education programme at Dublin City University in the period 2008-2012. It is at the intersection of these subject positions, between theory and practice, that professional development was explored through the ‘leadership problem’ of encouraging trainer colleagues to investigate the educational (...) potential of information and communications technologies for the development of their practice. Ultimately, this constituted a critical space for sustained dialogue between the self and the social in exploring professional subjectivity. The resources discussed supported the interrogation of social, cultural and historical conditions influencing self-understanding and narrative reasoning and movement from strategic to communicative reasoning. It is claimed that this has significance for the development of a more educational training practice, which expresses a concern for subjectivity and agency in the face of a growing ‘performativity’ in professional life.

This second article is divided into two sections.

The thesis presented in the final section is that powers can only come to completion by taking a “religious turn”. The notion of “assent” as a basic ingredient of human action is what connects the first to the second part of the essay. (shrink)

Working in he 1930s, Albert Lautman described with extraordinary clarity the new understanding of mathematics of that time. He delighted in the multiple manifestations of a common idea in different mathematical fields. However, he took the common idea to belong not to mathematics itself, but to an 'ideal reality' sitting above mathematics. I argue in this paper that now that we have a mathematical language which can characterize these common ideas, we need not follow Lautman to adopt his form of (...) Platonism. On the other hand, Lautman should be much better known than he is for pointing philosophy towards this most important feature of mathematics. (shrink)

According to the instrumentalism of Friedman and Machlup it is irrelevant whether the explanatory principles or “assumptions” of a theory satisfy any criterion of “plausibility,” “realism,” “credibility,” or “soundness.” In this view the main or only criterion for selecting theories is whether a theory yields empirically testable implications that turn out to be consistent with observations. All we should require or expect from a theory is that it is a useful instrument for the purpose of prediction. Considerations of the “efficiency” (...) of a theory for the purpose of ordering our experiences are permitted, but considerations of “plausibility” are not. “Explanatory assumptions” are not really explanatory in the sense that they claim to represent underlying causal processes in reality; they only serve to generate, by deduction, implications that are in accordance with as many observations as possible.
