The emergence of new technologies regularly involves comparisons with previous innovations. For instance, analogies with asbestos and genetically modified organisms have played a crucial role in the early societal debate about nanotechnology. This article explores the power of analogies in such debates and how they could be effectively and responsibly employed for imagining and governing emerging technologies in general and nanotechnology in particular. First, the concept of analogical imagination is developed to capture the explorative and anticipatory potential of analogies. Yet (...) analogies do not simply stimulate imagination, they also restrict it by framing emerging technologies in specific ways. Thus, second, the article argues that tracing the rhetorical and persuasive power of analogical arguments is essential for understanding how analogies are constructed to legitimise assessments, funding policies, and governance approaches. Third, the article addresses factors that account for the persuasiveness of analogies in debates about emerging technologies. The article concludes with reflections on how analogical imagination and an enhanced analogical sensibility for framing and persuasive effects can foster responsible research and innovation.

Most recent writing linking science and literature has concerned itself with challenges to the epistemological status of scientific knowledge in an attempt to demonstrate its contingency, arguing in the more radical efforts that the structures of science are no more than useful fictions. This essay also includes an epistemological comparison between science and literature, but instead of making grand or meta–statements about the nature of knowing generally in the two fields, mine is a much narrower aim. My exploration entails two (...) tasks. First, I provide a close–up look at a particular type of experiment, called the delayed–choice experiment, which clearly reveals the strangeness of the quantum world. In connection with this experiment, I discuss wave functions—mathematical expressions used by physicists to describe quantum behavior and predict the outcome of experiments involving quanta. Second, I look at Walt Whitman's “Song of Myself” focusing on the meaning of the “self” in the poem. My aim is to treat the object of study in each field as a “text” and to assert and demonstrate a parallel in the strategies of thought and response between physicists (“readers”) pondering the meaning and status of a wave function and poem readers pondering the meaning and status of the poem's self. In Whitman's “Song” we find an attempt to understand complex aspects of human experience that are said to transcend ordinary reality, an effort for which I believe there are parallels in the attempts of modern physicists to understand complex, nonintuitive aspects of the subatomic world. While not making the kind of broad claims eschewed above, I do suggest that this focused study has interesting implications since both the wave function and the poem's self force their respective sets of “readers” to confront questions of ultimacy—to consider, that is, epistemological and ontological issues of more than passing interest to students of science as well as those of metaphysics and theology.

In this paper, I discuss the discovery of the DNA structure by Francis Crick and James Watson, which has provoked a large historical literature but has yet not found entry into philosophical debates. I want to redress this imbalance. In contrast to the available historical literature, a strong emphasis will be placed upon analysing the roles played by theory, model, and evidence and the relationship between them. In particular, I am going to discuss not only Crick and Watson's well-known model (...) and Franklin's x-ray diffraction pictures (the evidence) but also the less well known theory of helical diffraction, which was absolutely crucial to Crick and Watson's discovery. The insights into this groundbreaking historical episode will have consequences for the ‘new’ received view of scientific models and their function and relationship to theory and world. The received view, dominated by works by Cartwright and Morgan and Morrison ([1999]), rather than trying to put forth a ‘theory of models’, is interested in questions to do with (i) the function of models in scientific practice and (ii) the construction of models. In regard to (i), the received view locates the model (as an idealized, simplified version of the real system under investigation) between theory and the world and sees the model as allowing the application of the former to the latter. As to (ii) Cartwright has argued for a phenomenologically driven view and Morgan and Morrison ([1999]) for the ‘autonomy’ of models in the construction process: models are determined neither by theory nor by the world. The present case study of the discovery of the DNA structure strongly challenges both (i) and (ii). In contrast to claim (i) of the received view, it was not Crick and Watson's model but rather the helical diffraction theory which served a mediating purpose between the model and the x-ray diffraction pictures. In particular, Cartwright's take on (ii) is refuted by a comparison of Franklin's bottom-up approach with Crick and Watson's top-down approach in constructing the model. The former led to difficulties, which only a strong confidence in the structure incorporated in the model could circumvent.

Psychologists investigating dreams in non-Western cultures have generally not considered the meanings of dreams within the unique meaning-structure of the person in his or her societal context. The study was concerned with explicating the indigenous system of dream interpretation of the Xhosa-speaking people, as revealed by acknowledged dream experts, and elaborating upon the life-world of the participants. Fifty dreams and their interpretations were collected from participants, who were traditional healers and their clients. A phenomenological methodology was adopted in explicating the (...) data. Themes explicated included : the physiognomy of the dreamer's life-world as revealed by significant dreams, the interpretation of significant dreams as revealed through action, and human bodiliness as revealed in dream interpretations. The participants' approach to dreams is not based upon an explicit theory, but upon an immediate and pathic understanding of the dream phenomenon. The understanding is based upon the interpreter's concrete understanding of the life-world, which includes the possibility of cosmic integration and continuity between personal and trans-personal realms of being.

The correspondence metaphor is useful in developing functional models of memory. However, the storehouse metaphor is still useful in developing structural and process models of memory. Traditional research techniques explore the structure of memory; everyday techniques explore the function of memory. We illustrate this point with two examples: amnesia and metamemory. In each phenomenon, both metaphors are useful.

This paper analyzes three contrasting strategies for modeling intentional agency in contemporary analytic philosophy of mind and action, and draws parallels between them and similar strategies of scientific model-construction. Gricean modeling involves identifying primitive building blocks of intentional agency, and building up from such building blocks to prototypically agential behaviors. Analogical modeling is based on picking out an exemplary type of intentional agency, which is used as a model for other agential types. Theoretical modeling involves reasoning about intentional agency in (...) terms of some domain-general framework of lawlike regularities, which involves no detailed reference to particular building blocks or exemplars of intentional agency. Given the contrasting procedural approaches that they employ and the different types of knowledge that they embody, the three strategies are argued to provide mutually complementary perspectives on intentional agency.

Why did Frege offer only proper names as examples of presupposition triggers? Some scholars claim that Frege simply did not care about the full range of presuppositional phenomena. This paper argues, in contrast, that he had good reasons for employing an extremely narrow notion of ‘Voraussetzung’. On Frege’s view, many devices that are now construed as presupposition triggers either express several thoughts at once or merely ‘illuminate’ a thought in a particular way. Fregean presuppositions, in contrast, are essentially tied to (...) names. (shrink)

Overall, Max Black's defense of the inductive support of inductive rules succeeds. Circularity is best explained in terms of epistemic conditions of inference. When an inference is circular, another inference token of the same type may, because of a difference of surrounding circumstances, not be circular. Black's inductive arguments in support of inductive rules fit this pattern: a token circular in some circumstances may be noncircular in other circumstances.

Philosophy’s adversarial argumentation style is often noted as a factor contributing to the low numbers of women in philosophy. I argue that there is a level of adversariality peculiar to philosophy that merits specific feminist examination, yet doesn’t assume controversial gender differences claims. The dominance of the argument-as-war metaphor is not warranted, since this metaphor misconstrues the epistemic role of good argument as a tool of rational persuasion. This metaphor is entangled with the persisting narrative of embattled reason, which, in (...) turn, is linked to the sexism-informed narrative of the “man of reason” continually warding off or battling “feminine” unreason.

In 1997, five decades after the publication of the landmark Hempel-Oppenheim article "Studies in the Logic of Explanation"([1948], 1970) Wesley Salmon published Causality and Explanation, a book that re-addresses the issue of scientific explanation. He provided an overview of the basic approaches to scientific explanation, stressed their weaknesses, and offered novel insights. However, he failed to mention Mary Hesse's approach to the topic and analyze her standpoint. This essay brings front and center Hesse's approach to scientific explanation formulated in the (...) 1960s and argues that rereading Hesse's account one can overcome the criticisms addressed towards another influential theory of explanation that of Bas van Fraassen's. Furthermore, it could bring the traditional philosophy of science into a fruitful conversation with science and technology studies and gender studies in science, technology and medicine. (shrink)

In this paper I propose a type-hierarchy approach to provide an intersubjective framework for the evaluation of evolutionary analogies. This approach develops David Hull’s and others’ attempts to provide full generalisation for selection processes, in order to show that sociocultural development and, particularly, scientific change can be considered as an instance of Darwinian selection. I argue that the recent work by Eileen Cornell Way on type hierarchies can offer the kind of generalisation needed to solve the main problems that still (...) affect Hull’s theory and to show that the evolutionary analogy is, after all, only a particular way of grouping phenomena together. If Hull’s main objective is a unified theory of selection, which supports the idea that science selection and natural selection obey the same laws, I also argue that the type hierarchy approach to models shows that this objective is unsustainable as it stands, and is in need of further development. I will firstly introduce the general outline of the type hierarchy approach to models. Then, after a brief recapitulation of Hull’s main points and difficulties, I will try and construct a hierarchy for a general abstraction of selection processes. Finally I will introduce the main criticisms that Hull’s work has faced from philosophers and scientists, and show how they compare with my proposal. (shrink)

My intention in this paper is to propose a conception of metaphorical meaning on which the meaning of a metaphor includes propositional as well as non-propositional features. I will make two general claims on behalf of the proposed account: first, it is intuitive; second, it is of theoretical value. In claiming that the proposed account is of theoretical value, I mean only that its adoption leads to an increased understanding of the nature of metaphor: of metaphorical thought and ofmetaphorical communication (...) in particular.

Reflection is today a watchword in many learning contexts. Experience is said to be transformed to knowledge when we reflect on it, university students are expected to acquire the ability to reflect critically, and we want practitioners to be reflective practitioners in order to improve their professional practice. If we consider what people mean when they talk about reflection in practice, we will discover that they often mean different things. Moreover, their conceptions of reflection are guided by images rather than (...) by definitions. This paper explores six distinct images of reflection and discusses the consequences of adopting one or more of these images in learning situations: (1) dedoublement, (2) analogical thinking, (3) mirror, (4) experiment, (5) puzzle solving, (6) criss-crossing a landscape. Reflective thinking can be improved if we are sensible of what we are reflecting about and according to which image of reflection we are doing it, since the step between using an image and seeing this image as a model is short. Using models, in turn, implies knowing their limits. (shrink)

According to the quotational theory of meaning ascriptions, sentences like “‘Bruder means brother” are abbreviated synonymy claims, such as “‘Bruder means the same as ‘brother’”. After discussing a problem with Harman’s version of the quotational theory, I present an amended version defended by Field. Then, I address Field’s responses to two arguments against the theory that revolve around translation and the understanding of foreign expressions. Afterwards, I formulate two original arguments against both Harman’s and Field’s versions of the theory. One (...) of them targets the hyperintensionality of quotations and the other raises a problem pertaining to variant spellings of words. (shrink)

We propose a theatrical Aesthetics of liberation understood as one that articulates imaginary, visual, or textual bridges between the opening to the context-world and its impact on subjectivity and that gives rise to a scenic production favorable to the conservation and improvement of life that raises opposition or rejection of those contexts that are not conducive to it. We will observe the productions of the theatrical scene in three moments of the recent Argentine past to visualize both the resistance and (...) denunciation of the decrease or disappearance of rights and the rejection of the necessary control of bodies and actions to impose the liberal/neoliberal model. We will look into scenes produced during the Argentine Revolution, stagings of the end of the 20th century responding to the exacerbation of neoliberalism, and finally, those produced during the last neoliberal restoration.

This work offers a challenge to the orthodox view that descriptive rules are non-normative and passive in their role and usage. It does so by arguing that, although lacking in normativity themselves, descriptive rules can be sources of normativity by way of the normative attitudes that can develop around them. That is, although descriptive rules typically depict how things are, they can also play a role in how things ought to be. In this way, the limited role that this type (...) of rule can play as either a basis for the development of normative reasons, or as explanatory reasons for action is identified and clarified. One desirable outcome of the analysis is a more complete view of what descriptive rules are and how they are utilized by agents. (shrink)

The contribution that may come from the general science of signs, semiotics, to the planning and development of education and learning at all levels, from early schooling through to university education and learning should not be neglected. As Umberto Eco claims in the “Introduction” to the Italian edition of his book Semiotica and Philosophy of Language (1984: xii, my trans.), “[general semiotics] is philosophical in nature, because it does not study a particular system, but posits the general categories in light (...) of which different systems can be compared. And for general semiotics philosophical discourse is neither advisable nor urgent: it is simply constitutive.” To the title of their book Semiotic Theory of Learning, at the centre of our attention in the present text, Andrew Stables, Winfried Nöth, Alin Olteanu, Sébastien Pesce, and Eetu Pikkarainen, rightly add the subtitle New Perspectives in the Philosophy of Education. This multivoiced contribution to research in learning and education in a semiotic framework has a unifying reference in the semiotics of Charles S. Peirce, but without disregarding an array of other distinguished exponents of the teaching and education sciences from different disciplines, semioticians and philosophers alike. This book, a polyphonic effort, with its appeal to “act otherwise,” and to do so investing in learning and education, no doubt makes a significant contribution in such a direction: education for transformation, for humanizing social change. Beyond evidencing what to us are particularly interesting aspects of the topics under discussion in Semiotic Theory of Learning, we also propose to continue and amplify this multivoiced dialogue. While highlighting still other aspects and contributions made by the same semioticians and philosophers presented by the authors of this book, involving such figures as Charles Peirce, Charles Morris, Thomas Sebeok, John Deely, etc., we have further introduced other voices made to resound throughout, whether directly or indirectly, like that of Victoria Welby, Mikhail Bakhtin, Emmanuel Levinas, Adam Schaff, Ferruccio Rossi-Landi, Marcel Danesi, Augusto Ponzio, and Genevieve Vaughan.

The aim of this paper is to use a frame-based account to explain some empirical findings regarding the accessibility of synaesthetic metaphors. Therefore, some results of empirical studies will be discussed with regard to the question of how much it matters whether the concept of the source domain in a synaesthetic metaphor is a scalar or a quality concept. Furthermore, typed frames are introduced, and it is explained how the notion of a minimal upper attribute can be used in the (...) analysis of adjective-noun compounds. Finally, frames are used to analyze synaesthetic metaphors; it turns out that they offer an adequate basis for the explanation of different accessibility rates found in empirical studies. (shrink)

The research guided by the correspondence metaphor is lauded for its emphasis on functional analysis, but the term “correspondence” itself needs clarification. Of the two terms in the relationship, only one is well defined. It is suggested that behavior at acquisition needs to be analyzed and that molecular principles from the learning laboratory might be useful in doing so.

Patina is the word used for the green or brown film formed on the surface of old bronze, an excess of which can mask the true characteristics of the original masterpiece. Filippo Baldinucci used the word patina in a modern sense for first time in his book “Tuscan Vocabulary of the Art of Design”. Metaphors have been part of philosophical speech since the time of Plato. This figure of speech is used to attempt to provide a sensitive presence of an (...) idea to improve understanding and to make a more vivid perception of that concept. On analysing the creative process of contemporary re-search on health topics and its further dissemination, we defend the epistemological thesis that there is always some degree of patina on an original article and this may obscure the underlying scientific work. Conclusion: We consider that patina in scientific papers is very different from the concept of epidemiological bias. We think that any researcher who reads an original article acts as a restorer of knowledge. If a reader is aware of the existence of scientific patina, that reader will know how to look through it and see the masterpiece hidden underneath. (shrink)

‘‘Adaptive radiation’’ is an evocative metaphor for explosive evolutionary divergence, which for over 100 years has given a powerful heuristic to countless scientists working on all types of organisms at all phylogenetic levels. However, success has come at the price of making ‘‘adaptive radiation’’ so vague that it can no longer reflect the detailed results yielded by powerful new phylogeny-based techniques that quantify continuous adaptive radiation variables such as speciation rate, phylogenetic tree shape, and morphological diversity. Attempts to shoehorn the (...) results of these techniques into categorical ‘‘adaptive radiation: yes/no’’ schemes lead to reification, in which arbitrary quantitative thresholds are regarded as real. Our account of the life cycle of metaphors in science suggests that it is time to exchange the spent metaphor for new concepts that better represent the full range of diversity, disparity, and speciation rate across all of life.

Military metaphors are pervasive in biomedicine, including HIV research. Rooted in the mind set that regards pathogens as enemies to be defeated, terms such as “shock and kill” have become widely accepted idioms within HIV cure research. Such language and symbolism must be critically examined as they may be especially problematic when used to express scientific ideas within emerging health-related fields. In this article, philosophical analysis and an interdisciplinary literature review utilizing key texts from sociology, anthropology, history, and Chinese and (...) African studies were conducted to investigate the current proliferation of military metaphors. We found the use of these metaphors to be ironic, unfortunate, and unnecessary. To overcome military metaphors we propose to give them less aggressive meanings, and/or replace them with more peaceful metaphors. Building on previous authors' work, we argue for the increased use of “journey” metaphors as meaningful, cross-culturally app... (shrink)

Koriat & Goldsmith propose that the correspondence metaphor captures the essence of everyday memory research. We suggest that correspondence is often not at issue because objective assessments of everyday events are frequently lacking. In these cases, other questions arise, such as how individuals evaluate the validity of memories and the significance they attach to those evaluations.

Investigations of metacognition – and also the application of the storehouse and correspondence metaphors – seem as appropriate for laboratory research as for naturalistic research. In terms of measurement, the only quantitative difference between the “input-bound percent correct” and “output-bound percent correct” is the inclusion versus exclusion (respectively) of omission errors in the denominator of the percentages.

How is it that metaphors are meaningful, yet we have so much trouble saying exactly what they mean? I argue that metaphoric thought is an act of imagination, mediated by the contingent form of human embodiment. Metaphoric cognition is an example of the productive interplay between intentional imagery and the body scheme, a process of imaginal modeling. The case of metaphor marks the intersection of linguistic and psychological processes and demonstrates the need for a multi-disciplinary approach not only in philosophy (...) of language, but in cognitive science and consciousness studies as well.

Koriat & Goldsmith are right in their claim that the “ecological” and “traditional” approaches to memory rely on different metaphors. But the underlying ecological metaphor is notcorrespondence(which in any case is not a metaphorical notion): it isaction. Remembering is a kind of doing; like most other forms of action it is purposive, personal, and particular.

This paper aims to show how medical scientists may use metaphor in ways closely parallel to poets. Those who believe metaphor has any role at all in science may describe its use in various ways. Associationists think metaphors are based upon likenesses, and collapse the notions of model and metaphor together. But, as an example from the work of Louis Pasteur suggests, metaphor need not be based upon likenesses. Rather it may play a role in making possible a model'sexplanatory significance. (...) Models may presuppose metaphors. The Pasteur example also suggests metaphor may play a part in creating likenesses through its role in classification and reclassification. It is in these ways that the use of metaphor in medical science most closely parallels that in poetry. (shrink)

This article discusses how the study of metaphoric and more generally, figurative language use contributes to critical discourse analysis. It shows how cognitive linguists’ recognition of metaphor as a fundamental means of concept- and argument-building can add to CDA's account of meaning constitution in the social context. It then discusses discrepancies between the early model of conceptual metaphor theory and empirical data and argues that discursive-pragmatic factors as well as sociolinguistic variation have to be taken into account in order to (...) make cognitive analyses more empirically and socially relevant. In conclusion, we sketch a modified cognitive approach informed by Relevance Theory within CDA. (shrink)

A recent perspective proposed by cognitive linguistics allows overcoming the traditional trend by confronting the special rhetorical strength of metaphor with its evident argumentative nature. In such a direction the psycho-semiotic approach frames each human event of sense making within the notion of diatext, underlining the dialogical tension between “text” and “context” of enunciation. Metaphor is a relevant resource of diatextual analysis since it opens unexpected views on the mysterious procedures that translate claims of meaning into discursive modes suitable to (...) specific situations. A corpus of empirical evidences, collected within the organizational context through narrative interviews, allows better understanding of the creative power of metaphors. (shrink)

Koriat & Goldsmith's thesis is provocative but has three problems: First, quantity and accuracy are not simply related, they are complementary. Second, the storehouse metaphor is not the driving force behind contemporary theories of memory and may not be viable. Third, the taxonomy is incomplete, leaving unclassified several extremely influential methods and measures, such as priming and response latency.

This commentary deals with criteria for assigning truth values to memory contents. A parallel with perception shows how truth values can be assigned by considering subjects' beliefs about the truth state of the memory content. This topic is also relevant to the study of processes of control over retrieval.
