Can a set of musical metaphors in a treatise on ethics reveal something about the nature and source of moral autonomy? This article argues that it can. It shows how metaphorical usage of words like tone, pitch, and concord in Adam Smith's Theory of Moral Sentiments can be understood as elements of an analogical model for morality. What this model tells us about morality depends on how we conceptualise music. In contrast to earlier interpretations of Smith's metaphors that have seen (...) music as an aesthetic object, this article sees music as a practice. Understood in this way, the analogy allows us to see morality too as a practice––as moral tuning. This in turn reveals a novel answer to the intractable problem of conventionalism: moral autonomy consists in the freedom inherent in the constant need to interpret and reinterpret the strictly formal ideal of perfect propriety.

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.

Este trabalho pretende sustentar que o melhor conceito para tratar da relação entre metáfora e linguagem é o da subdeterminação semântica. Entretanto, o modo mais comum de tratar o fenômeno das metáforas relega à pragmática a função de explicar como o significado metafórico de uma frase é um acarretamento gerado pelo contexto. Segundo este quadro, metáforas seriam indeterminadas semanticamente pois acarretamentos pragmáticos são virtualmente infinitos e não precisam remeter à proposição semanticamente expressa. Argumentamos, entretanto, as melhores alternativas para o tratamento (...) da questão nascem do debate entre contextualismo e minimalismo semânticos. Metáforas seriam casos de flexibilidade semântica também presentes em outros fenômenos linguísticos. Para o minimalismo, metáforas podem ser tratadas através da introdução de um operador lexical que garantiria a flexibilidade contextual necessária a termos semânticos contextualmente dependentes. Para o contextualismo, metáforas acontecem quando termos em uma frase funcionam como conceitos ad hoc e são passíveis de enriquecimentos pragmáticos. Apesar de não chegarem a uma única solução, o debate entre minimalismo e contextualismo oferece explicações do fenômeno que corroboram a hipótese da subdeterminação semântica defendida neste trabalho.

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)

The ‘prohibitionist’ idea that slurs have the same linguistic properties as their neutral counterparts hasn’t received much support in the literature. Here I offer a modified version of prohibitionism, according to which the taboo on using slurs is part of their conventional meaning. I conclude with explanations of the behaviour of slurs in embedded constructions.

In 1891 Cambridge biologist William Bateson (1861–1926) announced his idea that the symmetrical segmentation in living organisms resulted from energy peaks of some vibratory force acting on tissues during morphogenesis. He also demonstrated topographically how folding a radially symmetric organism could produce another with bilateral symmetry. Bateson attended many lectures at the Cambridge Philosophical Society and viewed mechanical models prepared by eminent physicists that illustrated how vibrations affected materials. In his subsequent research, Bateson utilized analogies and metaphors based upon his (...) observations of nature to build a thought model on the effects of vibrations on living tissue, because he realized that the chemistry and biology of his day lacked technologies to perform actual experiments on the subject. He concluded the production of organic segmentation was both a chemical and mechanical phenomenon. By the time of his death Bateson had incorporated new ideas about embryonic organizer regions to suggest a center from which a rhythmic force emanated and then produced the observed repetitive segmentation as a common feature in living organisms.

The purpose of this paper is to explore the semantics of metaphoric language in scientific contexts. According to the theory of metaphor advanced below, the benchmark of a metaphoric expression is the implicit transfer of semantic features across incongruous semantic fields. This transfer results in a conceptual variation of "meaning" in the receiving semantic field. Thus, the theory of metaphor rests on semantic field theory. Existing semantic approaches to metaphor are evaluated in Section 1. In Sections 2 and 3 an (...) alternative theory is introduced through an analysis of the mechanics of the feature transfer process followed by a discussion of some methodological cues for deciphering the metaphor's "meaning." As I explore in Section 4, this theory of metaphor explains how all metaphoric expressions are potentially literal depending on the general compliance of the community of speakers. Consequently, concept formation in scientific contexts is, in large measure, metaphoric. Finally, I argue in Section 5 that metaphoric concept formation is an essential aspect of scientific reasoning for the purpose of solving conceptual problems. (shrink)

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)

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)

This essay addresses Jacques Derrida’s theory of metaphor, as it has been handed to literary theory and continental philosophy. Our aim is to reassess the relationship between metaphor and metaphysics, using two distinct critical lenses. We will contrast Derrida’s influential position to an anachronistic author – Giambattista Vico. Vico initiated what is now called the romantic theory of metaphor, but the details of his theory are missing from current discussions. For this reason, Vico’s view is given closer attention. Two new (...) concepts are introduced: mute metaphor and heroic metaphor. These terms help specify precisely how metaphor can be conceived as a process of consciousness rather than a grammatical rule or grammatical exception. Finally, it is suggested that Vico’s theory is preferable to Derrida’s. Vico’s vision of metaphorical language is more fruitful and less problematic than Derrida’s, both methodologically and terminologically. The romanticism espoused by Vico also suggests itself to new modes of contemporary research concerning the purpose and function of metaphor within language. (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 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)

On the occasion of a first conference on Cognitive Science, it seems appropriate to review the basis of common understanding between the various disciplines. In my estimate, the most fundamental contribution so far of artificial intelligence and computer science to the joint enterprise of cognitive science has been the notion of a physical symbol system, i.e., the concept of a broad class of systems capable of having and manipulating symbols, yet realizable in the physical universe. The notion of symbol so (...) defined is internal to this concept, so it becomes a hypothesis that this notion of symbols includes the symbols that we humans use every day of our lives. In this paper we attempt systematically, but plainly, to lay out the nature of physical symbol systems. Such a review is in ways familiar, but not thereby useless. Restatement of fundamentals is an important exercise. (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.

The relation between theoretical models and metaphors has been studied since at least the 1950s. The relation between metaphors and mathematical modelling is less well researched. This article takes the media coverage of the foot and mouth modelling exercise in 2001 as an occasion to examine the metaphors of mathematical modelling that were proposed by the UK press during that time to make sense of this new scientific policy tool. One can detect a gradual change in metaphor use by the (...) newspapers from conceptualizing modellers as detectives and models as mapping tools to modellers as soldiers and heroes, to modellers as liars and models as tools to distort the truth. This seems to indicate a shift in reporting from seeing models as a legitimate and "objective" basis used by decision makers to pursue science-based policies towards seeing models as tools used to legitimize increasingly difficult political decisions.

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)

Meaning in literary texts such as poetry and novel etc., is not determined on the basis of a literal understanding of the words in it, but through a total evaluation of the devices such as metaphors and similes. This paper deals with metaphor to show its significance, to make us aware that metaphoric expressions do give a different kind of knowledge, and to pave the way to disclose a different kind of truth which is perhaps, more valuable than what the (...) literal sense provides. Ordinarily metaphorical use is taken for rhetorical purposes. Literalists of the Western and Indian philosophical traditions believe that it is only the literal or primary meaning that can give us a precise account of language. Metaphors are viewed by them as fuzzy, lies, not corresponding to actual states of affairs, non-propositional in character, not having truth-conditions, and thus not providing us with any knowledge or truth. However, this paper tries to work out the fundamentality of metaphor, how metaphor widens our experience of the world, and how it has the power to take us to an alternative world to introduce with some new truth by exploring certain notions of the Indian aestheticians.

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.

The value of accuracy and quantity as memory measures is assessed. It is argued that (1) accuracy does not measure correspondence (monitoring) because it ignores omissions and correct rejections, (2) quantity is confounded with monitoring in recall, and (3) in recognition, if targets and foils are unequal, both measures, even together, still ignore correct rejections.

Over the last few decades, theoretical discussions about metaphors have appeared with increasing frequency in the literature and, during the last fifteen years or so, such discussions have become more and more common in the methodology of economics. But what exactly is a metaphor? According to a tradition which dates back to Aristotle, a metaphor is the attribution to one object, A, of the name of another object, B, while this name or these qualities do not properly or normally belong (...) to A. Thus, a metaphor is present when a term used to describe A is a term which is already commonly used to name B. Defined in such a way, one must admit that metaphors are frequently found in economics as well as in other sciences. Let us consider, for example, a term like ‘elasticity’ which is extensively used by economists. According to the ordinary dictionary definition, this word designates a property of bodies by which they recover their initial form after having been submitted to a pressure; in a less technical sense, it refers to the flexibility of some bodies or to their responsiveness to pressures.

My basic argument is that a computer cannot distinguish between metaphor and nonsense. This would be my new “Turing Test.” I was very fond of a particular Italian poem, but I was told by an Italian friend that it was a hackneyed poem of little worth. I then taught myself to experience the poem alternately, as real poetry and as the silly nonsense that my friend claimed it really was. Having done so, I realized that I could do the same (...) with any metaphor, such as “having a green thumb.” Thinking about the nature of this switch, from the literal to the metaphorical, I also realized that it was the sort of change that could not be prescribed or even described: this, the basic aesthetic gesture, remains beyond the boundary of logical definition. It then dawned on me that it might provide a test for the validity of a “Turing Test,” by any definition. Can a computer track a mind as it goes through this transformation? I could not envisage such a possibility. This would be a “Turing Test” based on the discipline of aesthetics rather than on technology. It may even be argued that the ability to experience metaphor is the very definition of the human. (shrink)

Metaphorical meaning can be analyzed as triggered by an apparent communicative breach, an incongruity that leads to a default of the presumptive interpretation of a vehicle. This breach can be solved through contextual renegotiations of meaning guided by the communicative intention, or rather the presumed purpose of the metaphorical utterance. This paper addresses the problem of analyzing the complex process of reasoning underlying the reconstruction of metaphorical meaning. This process will be described as a type of abductive argument, aimed at (...) explaining how the vehicle can best contribute to the purpose of the utterance. This type of reasoning involves the analysis of the possible predicates that can be and usually are attributed to the vehicle, and the selection of the one that can support the implicit conclusion constituting the communicative goal of the metaphorical utterance. Metaphorical meaning, in this perspective, becomes the outcome of a complex process of meaning reconstruction aimed at providing the best explanation of the function of the vehicle within a discourse move.

Presuppositions are at the same time a crucial and almost neglected dimension of arguments and fallacies. Arguments involve different types of presuppositions, which can be used for manipulative purposes in distinct ways. However, what are presuppositions? What is their dialectical function? Why and how can they be dangerous? This paper intends to address these questions by developing the pragmatic approaches to presupposition from a dialectical perspective. The use of presuppositions will be analyzed in terms of presumptive conclusions concerning the interlocutor’s (...) acceptance of a proposition, which can be assessed as reasonable or unacceptable. Their dialectical function is described in terms of dark side commitments attributed to a collective "voice" representing what is commonly shared. For this reason, they count as attempts to include the presupposed contents into the hearer’s commitment store, which in some circumstances can reverse the burden of proof. The different manipulative strategies grounded on controversial presuppositions will be examined by showing the distinct roles that the latter play and the relationship between the degrees of presuppositional implicitness and the speaker’s burden of retraction.
