„An die Stelle des Klischees, Kierkegaard sei Kind seiner Zeit, könnte man deshalb mit Recht die weniger klischeehafte Aussage setzen, dass Kierkegaard durch seine Werke geboren worden ist, geschrieben durch seine Schriften. Aus demselben Grund lassen sich im Fall Kierkegaards Biographie und Bildung nicht trennen. Dass man sie auch nicht aufeinander reduzieren kann, dürfte entsprechend klar sein. Tut man das nämlich, raubt man dem göttlichen Erzähler die Möglichkeit, in dem Leben des Einzelnen zu Wort zu kommen – sowohl im Leben (...) Kierkegaards als auch im Leben eines jeden anderen Menschen.“ Joakim Garff Das Buch beginnt mit dem Themenkomplex Bildung, Biographie und Europa (Joakim Garff und Hartmut Rosenau). Kierkegaards Auseinandersetzungen mit dem Christentum (Jon Stewart fingiert einen möglichen Dialog darüber mit Hegel) und dessen institutionalisierten Formen, von Kierkegaard heftig kritisiert, z.B. in „Einübung im Christentum“ (dargestellt von Markus Pohlmeyer), mündeten in einen Kirchenkampf, der es Theologen und Theologinnen aller Konfessionen schwer macht€, Kierkegaard doch noch als einen der ihren zu akzeptieren, wie Eberhard Harbsmeier darlegt. Das Problem, Kierkegaard zu übersetzen, untersuchen Eberhard Schreiber, Tim Hagemann und Caren Wicka vor allem am Beispiel von Schrempfs geliebt-gehassten Übersetzungen. Klaus Müller und Marcello Neri zeigen, welch wichtige Impulse Kierkegaard dem italienischen Hermeneutiker Luigi Pareyson und dem deutschen Theologen Eugen Drewermann gab. (shrink)

Phronesis is essential for good decision‐making and actions. This literature review shows how phronesis has been discussed and related to elements of the field of administration and organizations. A search in the database systems Scopus, EBSCO, Web of Science, and Scielo, based on eligibility criteria, resulted in 43 theoretical and 14 empirical works. The analysis of these studies showed the most significant empirical contributions, the most cited authors, methods, journals, and central themes addressed in studies on phronesis to understand ethics (...) in business. From a virtue ethics perspective, we discuss the major theoretical and empirical contributions, as well as the implications of a restricted understanding of phronesis when it is treated apart from other elements of the virtue ethics framework. We present a synthesis of the concepts of phronesis, based on dimensions of magnitude and amplitude of the conceptions, ranging from formal to substantive phronesis, and covering individual, organizational, or societal levels of analysis. We argue that a substantive conception of phronesis within virtue ethics may improve our understanding of ethics because it assumes the interdependence of phronesis and moral virtues, integral anthropology, and the common good. We present a future research agenda, considering the study's limitations and findings. (shrink)

This paper analyses the communicative and epistemic value of retweeting (and more generally of reposting content on social media). Against a naïve view, it argues that retweets are not acts of endorsement, motivating this diagnosis with linguistic data. Retweeting is instead modelled as a peculiar form of quotation, in which the reported content is indicated rather than reproduced. A relevance-theoretic account of the communicative import of retweeting is then developed, to spell out the complex mechanisms by which retweets achieve their (...) communicative goals. The last section outlines the epistemic threats posed by the increasing prevalence of retweeting on social media, linking them to the low reputational, cognitive and practical costs linked to this emerging form of communication.

According to an influential view, asserting a proposition involves undertaking some “commitment” to the truth of that proposition. But accounts of what it is for someone to be committed to the truth of a proposition are often vague or imprecise, and are rarely put to work to define assertion. This article aims to fill this gap. It offers a precise characterisation of assertoric commitment, and applies it to define assertion. On the proposed view, acquiring commitment is not sufficient for asserting: (...) To assert, commitment must be acquired by explicitly presenting a proposition as true. (shrink)

Although the controversy between Malthus and Ricardo has long been considered to be an important source for the history of economic thought, it has hardly been the object of a careful study qua controversy, i.e. as a polemical dialogical exchange. We have undertaken to fill this gap, within the framework of a more ambitious project that places controversies at the center of an account of the history of ideas, in science and elsewhere. It is our contention that the dialogical co-text (...) is essential for reconstructing the meaning and the evolution of science. In the present paper we try to substantiate this contention by means of a pragma-rhetorical study of this particular controversy. First, we reconstruct, through an analysis of a chunk of the correspondence, a micro-level of specific moves and countermoves which constitute a sequential structure within which also meta-scientific and meta-controversial considerations play a role. We then move to a macro-level of analysis, looking for recurrent patterns of argumentation. Finally, we draw epistemological conclusions on the nature of rationality and progress as manifested in actual scientific controversies. (shrink)

The genetic code appeared on Earth with the first cells. The codes of cultural evolution arrived almost four billion years later. These are the only codes that are recognized by modern biology. In this book, however, Marcello Barbieri explains that there are many more organic codes in nature, and their appearance not only took place throughout the history of life but marked the major steps of that history. A code establishes a correspondence between two independent 'worlds', and the codemaker (...) is a third party between those 'worlds'. Therefore the cell can be thought of as a trinity of genotype, phenotype and ribotype. The ancestral ribotypes were the agents which gave rise to the first cells. The book goes on to explain how organic codes and organic memories can be used to shed new light on the problems encountered in cell signalling, epigenesis, embryonic development, and the evolution of language.

In this paper, we discuss the conceptual structure of cocktail recipes. This topic involves engaging questions for philosophers and food theorists due to some peculiar characteristics of cocktail recipes, such as the fact that they are standardised by international associations but, nonetheless, vagueness in some elements of the recipes introduces a degree of variability between cocktails of the same type. Our proposal is that a classical theory of concepts is unable to account for such peculiar features. Thus, only a hybrid (...) theoretical approach, combining definitional and prototypical aspects, can capture how cocktail recipes are usually conceptualised among bartenders and mixologists: while the spirit is usually a necessary (though not sufficient) condition for establishing whether an individual cocktail falls under a specific cocktail concept, all the other ingredients and procedures listed in recipes may vary to a certain extent. In order to assess whether variability in prototypical elements of cocktail recipes has any limitations, we exploit the notion of conceptual scheme applied to cocktail recipes and argue that, as long as the quality dimensions of a specific cocktail are respected, its identity remains unchanged regardless of changes in the ingredients or in its preparation.

What is lying? This entry provides a general overview of scholarly attempts to define lying in terms of necessary and sufficient conditions. First, it addresses the distinction between lying and misleading, considering whether only explicit statements can be lies. The second topic is insincerity, and how it can vary in degrees under conditions of uncertainty. Its final part discusses whether lying requires an intent to deceive and genuine assertoric force.

Orthogonality in model theory captures the idea of absence of non-trivial interactions between definable sets. We introduce a somewhat opposite notion of cohesiveness, capturing the idea of interaction among all parts of a given definable set. A cohesive set is indecomposable, in the sense that if it is internal to the product of two orthogonal sets, then it is internal to one of the two. We prove that a definable group in an o-minimal structure is a product of cohesive orthogonal (...) subsets. If the group has dimension one, or it is definably simple, then it is itself cohesive. As an application, we show that an abelian group definable in the disjoint union of finitely many o-minimal structures is a quotient, by a discrete normal subgroup, of a direct product of locally definable groups in the single structures.

The increasing availability of brain data within and outside the biomedical field, combined with the application of artificial intelligence (AI) to brain data analysis, poses a challenge for ethics and governance. We identify distinctive ethical implications of brain data acquisition and processing, and outline a multi-level governance framework. This framework is aimed at maximizing the benefits of facilitated brain data collection and further processing for science and medicine whilst minimizing risks and preventing harmful use. The framework consists of four primary (...) areas of regulatory intervention: binding regulation, ethics and soft law, responsible innovation, and human rights. (shrink)

The use of Intelligent Assistive Technology in dementia care opens the prospects of reducing the global burden of dementia and enabling novel opportunities to improve the lives of dementia patients. However, with current adoption rates being reportedly low, the potential of IATs might remain under-expressed as long as the reasons for suboptimal adoption remain unaddressed. Among these, ethical and social considerations are critical. This article reviews the spectrum of IATs for dementia and investigates the prevalence of ethical considerations in the (...) design of current IATs. Our screening shows that a significant portion of current IATs is designed in the absence of explicit ethical considerations. These results suggest that the lack of ethical consideration might be a codeterminant of current structural limitations in the translation of IATs from designing labs to bedside. Based on these data, we call for a coordinated effort to proactively incorporate ethical considerations early in the design and development of new products. (shrink)

It is shown that information and meaning can be defined by operative procedures, and that we need to recognize them as new types of natural entities. They are not quantities (neither fundamental nor derived) because they cannot be measured, and they are not qualities because they are not subjective features. Here it is proposed to call them nominable entities, i.e., entities which can be specified only by naming their components in their natural order.

Secondo la definizione “standard”, la menzogna è definita da quattro condizioni necessarie, congiuntamente sufficienti. La prima (condizione dell’asserto) richiede che il parlante proferisca un asserto in una frase dichiarativa dotata di senso compiuto. La seconda (condizione dell’insincerità), stabilisce che il parlante debba credere falso il contenuto proposizionale (p) del suo asserto, e la terza (condizione dell’interlocutore) richiede che l’asserto sia rivolto a un interlocutore. Secondo l’ultima condizione (condizione dell’intenzione di ingannare), il parlante deve avere l’intenzione di far credere all’interlocutore che (...) p è vero. Nei primi 5 capitoli di questa tesi discuto pregi e difetti di ognuna di queste condizioni. Nell’ultimo capitolo propongo una lettura pragmatica della menzogna, intesa come asserzione insincera, toccando questioni legate alla teoria degli atti linguistici e delle implicature conversazionali.

Not every speech act can be a lie. A good definition of lying should be able to draw the right distinctions between speech acts that can be lies and speech acts that under no circumstances are lies. This paper shows that no extant account of lying is able to draw the required distinctions. It argues that a definition of lying based on the notion of ‘assertoric commitment’ can succeed where other accounts have failed. Assertoric commitment is analysed in terms of (...) two normative components: ‘accountability’ and ‘discursive responsibility’. The resulting definition of lying draws all the desired distinctions, providing an intensionally adequate analysis of the concept of lying. (shrink)

A new definition of lying is gaining traction, according to which you lie only if you say what you know to be false. Drawing inspiration from “New Evil Demon” scenarios, I present a battery of counterexamples against this “Knowledge Account” of lying. Along the way, I comment upon the methodology of conceptual analysis, the moral implications of the Knowledge Account, and its ties with knowledge-first epistemology.

In a recent book (_Lying and insincerity_, Oxford University Press, 2018), Andreas Stokke argues that one lies iff one says something one believes to be false, thereby proposing that it becomes common ground. This paper shows that Stokke’s proposal is unable to draw the right distinctions about insincere performative utterances. The objection also has repercussions on theories of assertion, because it poses a novel challenge to any attempt to define assertion as a proposal to update the common ground.

In this much-anticipated revision and translation of Scienza e Retorica, Marcello Pera argues that rhetoric is central to the making of scientific knowledge. Pera begins with an attack of what he calls the "Cartesian syndrome"--the fixation on method common to both defenders of traditional philosophy of science and its detractors. He argues that in assuming the primacy of methodological rules, both sides get it wrong. Scientific knowledge is neither the simple mirror of nature nor a cultural construct imposed by (...) contingent interests, thus we must replace the idea of the scientific method with that of scientific rhetoric. Pera proposes a new dialectics of science to overcome the tension between normative and descriptive philosophies of science by focusing on the rhetoric in the proposition, defense, and argumentation of theories. Examining the uses of rhetoric in debates drawn from Galileo’s Dialogues, Darwin’s Origins, and the Big Bang-Steady State controversy in cosmology, Pera shows how the conduct of science involves not just nature and the inquiring mind, but nature, the inquiring mind, and a questioning community which, through the process of attack, defense, and dispute, determines what is science. Rhetoric, then, is an essential element in the constitution of science as the practice of persuasive argumentation through which results gain acceptance. (shrink)

Metzinger’s claim that there are no such things as selves has given rise to a lot of discussions. By examining the notion of self used by Metzinger, I want to clarify what he means when saying that nobody ever was or had a self. Furthermore, I want to examine if there could be a notion of ‘self’ which is compatible with the Self- Model Theory of Subjectivity (SMT). I will argue that there is a notion of self which is not (...) only compatible with the SMT, but that the SMT also provides the theoretical framework for developing such a notion. (shrink)

Is truth the rule or the aim of assertion? Philosophers disagree. After reviewing the available evidence, the hypothesis that truth is the aim of assertion is defended against recent attempts to prove that truth is rather a rule of assertion.

There is a fundamental disagreement about which norm regulates assertion. Proponents of factive accounts argue that only true propositions are assertable, whereas proponents of non-factive accounts insist that at least some false propositions are. Puzzlingly, both views are supported by equally plausible (but apparently incompatible) linguistic data. This paper delineates an alternative solution: to understand truth as the aim of assertion, and pair this view with a non-factive rule. The resulting account is able to explain all the relevant linguistic data, (...) and finds independent support from general considerations about the differences between rules and aims. (shrink)

All’interno del dibattito sulla definizione filosofica della menzogna, alcuni autori hanno sostenuto che mentire è sempre sbagliato. Margolis, in particolare, ha espresso la tesi radicale secondo cui “mentire è moralmente sbagliato” è una tautologia. Nella prima parte dell’articolo introduco la tesi di Margolis, e ne difendo la plausibilità contro le semplificazioni che ha subito all’interno del dibattito filosofico, mostrando che l’applicazione condizionale del predicato “sbagliato” consente di trattare in modo adeguato alcune menzogne intuitivamente giustificabili. Nella seconda parte argomento che, nonostante (...) questo stratagemma, non è possibile difendere la tesi che “mentire è moralmente sbagliato” sia una tautologia, perché bisognerebbe assumere che “mentire è moralmente sbagliato” sia una condizione necessaria fra quelle che definiscono il concetto stesso di menzogna. Questo non è desiderabile perché, come dimostro nella parte finale del mio articolo, ogni definizione di menzogna che incorpori requisiti morali nelle sue condizioni necessarie é destinata a contraddire le intuizioni del senso comune su che cos’é una menzogna. La conclusione è che la tesi che “mentire è moralmente è sbagliato” è una tautologia non può essere difesa, se non al prezzo, troppo alto, di ridefinire in modo controintuitivo il significato del termine “menzogna”.

: If we were asked to draw a graph to represent the distribution of consciousness in the world around us based on objective criteria, we would definitely be in trouble. The two objective parameters that have been traditionally considered as a guide – the complexity of behavior and brain size – lead to paradoxical conclusions and turn out to be unsatisfactory, to say the least. We need to find novel, reliable metrics. However, these can be identified, validated and calibrated only (...) if we first tackle seriously the problem of recognizing consciousness in our fellow humans, a task which is far from being obvious. Keywords: Consciousness; Animal; Brain; Behaviour; Coma La distribuzione della coscienza: un difficile diagramma cartesiano Riassunto: Se ci chiedessero di tracciare un grafico per rappresentare la distribuzione della coscienza nel mondo che ci circonda su una base oggettiva, ci troveremmo sicuramente in difficoltà. I due criteri oggettivi che sono stati tradizionalmente presi in considerazione come guida – la complessità del comportamento e la dimensione del cervello – conducono a conclusioni paradossali rivelandosi, come minimo, insoddisfacenti. È necessario individuare altre misure. Ma queste potranno essere individuate, validate e calibrate soltanto se prima affronteremo seriamente il problema di riconoscere la coscienza nell’uomo, un compito tutt’altro che scontato.

An alternative approach to analyze the nonrelativistic quantum dynamics of a rigid and extended charged particle taking into account the radiation reaction is discussed with detail. Interpretation of the field operators as annihilation and creation ones, theory of perturbations and renormalization are not used. The analysis is carried out in the Heisenberg picture with the electromagnetic field expanded in a complete orthogonal basis set of functions which allows the electromagnetic field to satisfy arbitrary boundary conditions. The corresponding coefficients are the (...) field operators which satisfy the usual commutation relations. A nonlinear equation of motion for the charged particle is obtained. A careful consideration of the quantum effects allows the derivation of a linear equation of motion which is free of both runaway solutions and preacceleration, even for a point charge. Also, the electromagnetic mass, which is defined as the coefficient of the acceleration operator, vanishes for a point particle. However, this does not mean that the results are free of ambiguities which are exhibited and discussed. (shrink)

The essays in this book will be an invaluable source of inspiration for economists interested in economic theory and in the evolution of economic thought. They will also be of interest to postgraduate and research students specialising in economic theory and in the history of economic thought. (shrink)

Assertions are our standard communicative tool for sharing and acquiring information. Recent empirical studies seemingly provide converging evidence that assertions are subject to a factive norm: you are entitled to assert a proposition p only if p is true. All these studies, however, assume that we can treat participants' judgments about what an agent 'should say' as evidence of their intuitions about assertability. This paper argues that this assumption is incorrect, so that the conclusions drawn in these studies are unwarranted. (...) It shows that most people do not interpret statements about what an agent 'should say' as statements about assertability, but rather as statements about what is in the agent's interest to do. It identifies some effective measures to force the intended reading of statements about what an agent 'should say', and shows that when these measures are implemented, people's judgments consistently and overwhelmingly align with non-factive accounts of assertion.

Can fictions make genuine assertions about the actual world? Proponents of the ‘Assertion View’ answer the question affirmatively: they hold that authors can assert, by means of explicit statements that are part of the work of fiction, that something is actually the case in the real world. The ‘Nonassertion’ View firmly denies this possibility. In this paper, I defend a nuanced version of the Nonassertion View. I argue that even if fictions cannot assert, they can indirectly communicate that what is (...) recounted as fictional is actually true. I show that this view is supported by independent linguistic data, and that it is able to defuse the objections that are typically raised against the Nonassertion View. I conclude by showing that this position has some interesting implications for testimonial cognitivism about fiction. (shrink)

How can we capture the intuitive distinction between lying and misleading? According to a traditional view, the difference boils down to whether the speaker is saying (as opposed to implying) something that they believe to be false. This view is subject to known objections; to overcome them, an alternative view has emerged. For the alternative view, what matters is whether the speaker can consistently deny that they are committed to knowing the relevant proposition. We point out serious flaws for this (...) alternative view, and sketch a simpler alternative that incorporates key insights of the traditional view. (shrink)

When subjects view stimulation of a rubber hand while feeling congruent stimulation of their own hand, they may come to feel that the rubber hand is part of their own body. This illusion of body ownership is termed ‘Rubber Hand Illusion’ . We investigated sensitivity of RHI to spatial mismatches between visual and somatic experience. We compared the effects of spatial mismatch between the stimulation of the two hands, and equivalent mismatches between the postures of the two hands. We created (...) the mismatch either by adjusting stimulation or posture of the subject’s hand, or, in a separate group of subjects, by adjusting stimulation or posture of the rubber hand. The matching processes underlying body ownership were asymmetrical. The illusion survived small changes in the subject’s hand posture, but disappeared when the same posture transformations were applied to the rubber hand. Mismatch between the stimulation delivered to the subject’s hand and the rubber hand abolished the illusion. The combination of these two situations is of particular interest. When the subject’s hand posture was slightly different from the rubber hand posture, the RHI remained as long as stimulation of the two hands was congruent in a hand-centred spatial reference frame, even though the altered posture of the subject’s hand meant that stimulation was incongruent in external space. Conversely, the RHI was reduced when the stimulation was incongruent in hand-centred space but congruent in external space. We conclude that the visual–tactile correlation that causes the RHI is computed within a hand-centred frame of reference, which is updated with changes in body posture. Current sensory evidence about what is ‘me’ is interpreted with respect to a prior mental body representation. (shrink)

[1] Contributi -- [2] Rassegne bibliografiche.

In a recent article, Krauss (2017) raises some fundamental questions concerning (i) what the desiderata of a definition of lying are, and (ii) how definitions of lying can account for partial beliefs. This paper aims to provide an adequate answer to both questions. Regarding (i), it shows that there can be a tension between two desiderata for a definition of lying: 'descriptive accuracy' (meeting intuitions about our ordinary concept of lying), and 'moral import' (meeting intuitions about what is wrong with (...) lying), vindicating the primacy of the former desideratum. Regarding (ii), it shows that Krauss' proposed 'worse-off requirement' meets neither of these desiderata, whereas the 'comparative insincerity condition' (Marsili 2014) can meet both. The conclusion is that lies are assertions that the speaker takes to be more likely to be false than true, and their distinctive blameworthiness is a function of the extent to which they violate a sincerity norm.

In a series of articles (Pagin, 2004, 2009), Peter Pagin has argued that assertion is not a social speech act, introducing a method (which we baptize ‘the P-test’) designed to refute any account that defines assertion in terms of its social effects. This paper contends that Pagin's method fails to rebut the thesis that assertion is social. We show that the P-test is both unreliable (because it overgenerates counterexamples) and counterproductive (because it ultimately provides evidence in favor of some social (...) accounts). Nonetheless, we contend that assertion is not fully social. We defend an intermediate view according to which assertion is only a partly social speech act: assertions both commit the speaker to a proposition (a social component) and present their propositional content as true (a non-social component). The upshot is that assertion is in some important respect social, although it cannot be defined solely in terms of its social effects. (shrink)

‘Particularism’ and ‘generalism’ refer to families of positions in the philosophy of moral reasoning, with the former playing down the importance of principles, rules or standards, and the latter stressing their importance. Part of the debate has taken an empirical turn, and this turn has implications for AI research and the philosophy of cognitive modeling. In this paper, Jonathan Dancy’s approach to particularism (arguably one of the best known and most radical approaches) is questioned both on logical and empirical grounds. (...) Doubts are raised over whether Dancy’s brand of particularism can adequately explain the graded nature of similarity assessments in analogical arguments. Also, simple recurrent neural network models of moral case classification are presented and discussed. This is done to raise concerns about Dancy’s suggestion that neural networks can help us to understand how we could classify situations in a way that is compatible with his particularism. Throughout, the idea of a surveyable standard—one with restricted length and complexity—plays a key role. Analogical arguments are taken to involve multidimensional similarity assessments, and surveyable contributory standards are taken to be attempts to articulate the dimensions of similarity that may exist between cases. This work will be of relevance both to those who have interests in computationally modeling human moral cognition and to those who are interested in how such models may or may not improve our philosophical understanding of such cognition.

According to an influential hypothesis, the speech act of assertion is subject to a single 'constitutive' rule, that takes the form: "One must: assert that p only if p has C". Scholars working on assertion interpret the assumption that this rule is 'constitutive' in different ways. This disagreement, often unacknowledged, threatens the foundations of the philosophical debate on assertion. This paper reviews different interpretations of the claim that assertion is governed by a constitutive rule. It argues that once we understand (...) the full import of assuming that assertion is governed by a constitutive rule, it becomes clear that some fundamental assumptions of the current debate are mistaken, and others unwarranted.

A simple recurrent artificial neural network is used to classify situations as permissible or impermissible. The trained ANN can be understood as having set up a similarity space of cases at the level of its internal or hidden units. An analysis of the network’s internal representations is undertaken using a new visualization technique for state space approaches to understanding similarity. Insights from the literature on moral philosophy pertaining to contributory standards will be used to interpret the state space set up (...) by the ANN as being structured by implicit reasons. The ANN, on its own, is not capable of explicitly representing or offering reasons to itself or others. That said, the low level similarity space set up by the network could be made available to higher order processes that exploit it for case-based reasoning. It is argued that for normative purposes, similarity could be seen as a contributor to procedural coherence in case-based reasoning and local forms of substantive coherence, but not to global forms of coherence given the computational complexity of managing those more ambitious forms of coherence.

Biosemiotics is the synthesis of biology and semiotics, and its main purpose is to show that semiosis is a fundamental component of life, i.e., that signs and meaning exist in all living systems. This idea started circulating in the 1960s and was proposed independently from enquires taking place at both ends of the Scala Naturae. At the molecular end it was expressed by Howard Pattee’s analysis of the genetic code, whereas at the human end it took the form of Thomas (...) Sebeok’s investigation into the biological roots of culture. Other proposals appeared in the years that followed and gave origin to different theoretical frameworks, or different schools, of biosemiotics. They are: (1) the physical biosemiotics of Howard Pattee and its extension in Darwinian biosemiotics by Howard Pattee and by Terrence Deacon, (2) the zoosemiotics proposed by Thomas Sebeok and its extension in sign biosemiotics developed by Thomas Sebeok and by Jesper Hoffmeyer, (3) the code biosemiotics of Marcello Barbieri and (4) the hermeneutic biosemiotics of Anton Markoš. The differences that exist between the schools are a consequence of their different models of semiosis, but that is only the tip of the iceberg. In reality they go much deeper and concern the very nature of the new discipline. Is biosemiotics only a new way of looking at the known facts of biology or does it predict new facts? Does biosemiotics consist of testable hypotheses? Does it add anything to the history of life and to our understanding of evolution? These are the major issues of the young discipline, and the purpose of the present paper is to illustrate them by describing the origin and the historical development of its main schools. (shrink)

David Bohm's interpretation of quantum mechanics yields a quantum potential, Q. In his early work, the effects of Q are understood in causal terms as acting through a real (quantum) field which pushes particles around. In his later work (with Basil Hiley), the causal understanding of Q appears to have been abandoned. The purpose of this paper is to understand how the use of certain metaphors leads Bohm away from a causal treatment of Q, and to evaluate the use of (...) those metaphors. (shrink)

Groups, like individuals, can communicate. They can issue statements, make promises, give advice. Sometimes, in doing so, they lie and deceive. The goal of this paper is to offer a precise characterisation of what it means for a group to make an assertion and to lie. I begin by showing that Lackey’s influential account of group assertion is unable to distinguish assertions from other speech acts, explicit statements from implicatures, and lying from misleading. I propose an alternative view, according to (...) which a group asserts a proposition only if it explicitly presents that proposition as true, thereby committing to its truth. This proposal is then put to work to define group lying. While scholars typically assume that group lying requires (i) a deceptive intent and (ii) a belief in the falsity of the asserted proposition, I offer a definition that drops condition (i) and significantly broadens condition (ii).
